What’s On My Mind: Solving Real Problems With AI

This week, let’s extend our use of AI as a practical research and recommendation tool to deal with stress. Now, I’ll start with a huge, huge disclaimer.

• I am not a medical professional.
• I do not give medical advice.
• Before making any changes to your health and wellness regimen, consult your qualified healthcare provider for advice specific to your situation.
• You waive any and all liability for, well, anything from this newsletter and from me, my company, my proxies, representatives, and others.

Okay, whew.

I had a thought recently: does all the stress that everyone’s under all the time these days have a specific impact? Regardless of your point of view, politics, geography, or life, chances are you’re under a fair bit of stress – and chronic stress at that.

We know stress is bad generally. That’s not news. But my specific wondering was, what does chronic stress do to us mentally?

Here’s why. Ever since November, I’ve found myself struggling more and more with things like memory, like remembering stuff. There’s just so much to pay attention to. And that got me wondering: how does stress impact executive function, things like attention, memory, emotional regulation, etc.?

I know the general, broad, ungrounded answer: it affects things adversely. Chronic anything tends to affect things adversely.

But that’s not enough. That’s not grounded in facts, in research, in data, in science. Despite the current vibe, opinion is not science, and given what I do for a living, data and science are kind of my thing.

So, what did I do?

Part 1: Do The Research

I specifically needed to find research broadly about how chronic stress impacts the brain, from neurochemistry to psychology. Today’s AI-enabled search engines, such as ChatGPT Search, Deepseek, Gemini 1.5 Deep Research, and Perplexity are all capable of doing in-depth research, but you have to give them strict parameters. If you don’t, they tend to find the fastest, easiest results – not the most thorough or correct ones.

Here’s the prompt I used:

You’re a world class researcher. You know academic journals, academic publishing, systematic reviews, meta-analysis, PRISMA, DOI locators, open access journals.
Your research task today is:
Identify and collate papers about the impact of chronic stress on executive function, with an emphasis on neurotransmitters and neuromodulators such as cortisol. The source of chronic stress should be something like ingesting a constant stream of bad news on social media and the news. What are the effects of chronic stress on the body? What are the effects of chronic stress on executive function and memory? How might chronic stress mimic disorders like ADHD, generalized anxiety disorder, and other similar disorders?

Restrictions and conditions:
– Use only research published after January 1, 2015
– Use only research from credentialed academic journals and scientific publications that have been peer reviewed
– All research must be non-retracted
– All research must have valid DOI numbers. Reject any result without a DOI number
– Produce all the DOI numbers in your citations
– Prefer sources that are PDF documents
– Explicitly reject mainstream media news sources such as CNN or Fox News, as these are not credentialed academic journals or scientific publications
– Explicitly reject consumer health news sources such as Self Magazine, Men’s Health, Women’s Health, and similar publications, as these are not credentialed academic journals or scientific publications
– Explicitly reject all social media content such as Reddit, Twitter/X, YouTube, and similar publications, as these are not credentialed academic journals or scientific publications
– Order your results in order of relevance to the research task
– There is no limit on the number of valid results you may gather. Gather all available valid results that meet these conditions

Stepping through this briefly, I use a short role statement mainly for the jargon, following by the problem, then relevant information, then success measures, mirroring the Trust Insights PRISM framework. Since tools like Perplexity have a reasoning option, this makes the most sense.

The tools all come back with AI-generated summaries. I ignore those. They’re unhelpful.

What they do come back with is sources, and I love sources. Sources from credible academic journals and peer-reviewed publications because, for as much scandal and as many problems as there are in academia, they pale in comparison to the absolute garbage you find on the public internet. I’d take a pre-print paper over Madame Peony’s Rectal Healing Crystal Magic any day.

With each source, I download the PDFs and save them to a folder on my desktop. In the USA, the federal government is deleting research left and right, so it’s a good idea to make copies of anything you’ve found in case it vanishes the next day; thousands of papers and datasets from the CDC and NIH have been deleted by the government this year, and getting archived copies is possible, but a pain in the butt. It’s a best practice to always make and save copies of the data you’re using. You never know when you’ll need it.

There’s a good chance at this point you’ll have dozens of sources, especially if you decide to use more than one research tool (which is generally a good idea). For example, if you use Google Deep Research and Perplexity Deep Research, you might find different sources. Grab all the relevant ones.

Part 2: Synthesis

The next part is to use a locked RAG system to synthesize the data. Let’s unpack that sentence. A RAG system stands for retrieval augmented generation. When you use generative AI, you have the option of providing data to it. You can do this in a variety of ways, from simply pasting information into a prompt to uploading documents to putting documents in a special database for AI to consult. That latter option is retrieval augmented generation; AI tech companies build a system where the AI knows to consult the library of documents you’ve uploaded first.

Some systems are locked, meaning that if you didn’t upload information that you have questions about, the AI will simply refuse to answer the question. It’ll say “Sorry Dave, I’m unable to answer that question” and then open the pod bay doors. Locked RAG systems are super useful when you want to avoid hallucination, which is when AI tries to be helpful and makes up information to fulfill your request, even if that information has no basis in fact.

In areas like law, finance, and health, that’s canonically a Bad Idea™. Hence we use locked RAG systems for any kind of information retrieval.

Now, you might say, well, what’s wrong with the synthesis put together by Perplexity / Gemini / OpenAI Deep Research? A few things. First, they don’t always get all the sources right, even with the best prompting. Second, we want to review the sources ourselves, and see the citations in context from the sources.

As we did with the health and fitness episode earlier this year, there’s something to be said for looking at the source material yourself. That’s why, for this particular application, we’ll use Google’s NotebookLM. The free version allows you to use up to 50 sources; the paid version allows you to use up to 300. Depending on how often you do research like this, you might want to upgrade to the paid version.

We load up all the sources into NotebookLM and now we start to ask questions of it. Here’s an example prompt, specific to the question I wanted to answer:

You’re an expert in neurochemistry, neurobiology, psychology. You specialize in understanding stress effects on the brain. Based on the sources provided, analyze how, if at all, chronic stress impacts the executive function of the brain. What are the effects? Order the effects in terms of severity from most to least.

You might wonder, why do we need to do this when we’re providing all the data? The underlying model of NotebookLM is Google’s Gemini 2 Flash, which means that it still benefits from things like role statements. It may be restricted in what knowledge it can access (by design) but it’s still an LLM at heart, so any steering we can provide helps to further encourage good outputs.

If we’ve done a good job of pulling accurate, trustworthy sources, we’ll get a strong answer to our question, backed by plenty of citations:

---

• Impaired Cognitive Function:
  • Chronic stress impairs several executive functions, including planning, decision-making, and impulse control.
  • It leads to difficulties in concentration, problem-solving, and information retention.
  • Working memory is significantly impaired.
  • Chronic stress is associated with poor performance in tests of attentional shifting.
  • It can also lead to cognitive decline and memory problems, particularly in older adults.
• Functional Impairments:
  • Chronic stress biases decision-making strategies towards habitual responses.
  • It impairs the ability to regulate emotions and cope with stress.
  • There is a negative impact on attentional bias to threat-related stimuli.
  • Chronic stress can contribute to the development of psychiatric disorders.

---

There was a ton more in the results, including literal degeneration of your brain, which is scary as hell. You can download a PDF of the results here, if you’re curious.

We might want to pursue several different angles or levels of depth to our questions. In this particular example, I might want to spend more time examining and decomposing the different aspects of executive function, such as attention, emotional regulation, and memory.

That said, just based on these results alone, it’s clear that chronic stress will definitely show up in your memory and in particular your ability to easily shift from task to task. If you feel chronically stressed, you might notice these symptoms too.

Part 3: Solutions

Now that we’ve identified the problem, what about solutions? Well, it turns out in this particular case, with all the research we compiled, there are plenty of solutions to be had. I asked NotebookLM for exactly that.

Based on the sources provided, what are the known, effective solutions for reducing chronic stress and in particular, cortisol levels? List solutions in terms of efficacy, most effective to least effective. Indicate whether a solution is a pharmaceutical intervention or a non-pharmaceutical intervention.

What it came back with, unsurprisingly, is a nice list of solutions:

---

Based on the provided sources, the most effective solutions for reducing chronic stress and cortisol levels, ranked from most to least effective, are as follows. It is important to note that efficacy can vary based on individual circumstances and the specific nature of the stressor.

Most Effective Interventions
* Meditation (Non-pharmaceutical):
* Meditation, in general, is a highly effective method for stress and cortisol reduction. Longer meditation programs tend to be more effective.
* Mindfulness-Based Stress Reduction (MBSR) combines mindfulness meditation with elements of cognitive behavioral therapy (CBT) and has been shown to be effective in reducing self-reported stress, decreasing cortisol levels, enhancing emotional regulation, and improving pain perception.
* Mindfulness meditation has moderate benefits for reducing symptoms of anxiety and depression.
* Meditation interventions are particularly beneficial for individuals at risk for elevated cortisol levels due to mental or somatic illnesses or stressful life situations.
* Integrative Body-Mind Training (IMBT) which combines mindfulness training, body relaxation, and mental imagery is also effective.
* Various forms of meditation, including zen or transcendental meditation, offer similar benefits.
* Meta-analyses indicate meditation has a significant medium effect on changing cortisol levels.

---

Again, there were a ton more results, but that would make this newsletter the length of a novella.

I hadn’t heard of the specific practice of Mindfulness-Based Stress Reduction, or MBSR. I asked about it and got back a short summary, so I went back to step 1 and fished out a bunch of new sources to add to the notebook. With that, I had a much more clear idea of what MBSR entailed.

Now, this is a good academic solution, in that we have confirmation from reviewed, researched, credible sources about how we might be able to reduce our levels of stress, and the answer is meditation. But this is theoretical, academic in nature. It’s not something we can do something with, other than to ask our qualified healthcare provider for a referral.

Suppose we wanted to get started on something today? Basic, breath-focused meditation is about as basic as it gets and in terms of side effects, for healthy individuals there are almost none. Again, I’m not a doctor and I can’t give medical advice, but as far as low-hanging fruit goes, this is as low as it gets.

Now, what if we wanted to adopt a basic meditation practice but we need a little basic technology to help us? Maybe something as simple and as easy as a web page that showed us what to do and when to do it? Could we make such a thing?

With generative AI, the answer is yes, absolutely, and we’ll build this step by step. The best part of this approach is that it’s entirely on your computer, you pay nothing for it ever, and it’s yours. The only skills you’ll need are the ability to prompt an image generation model and the ability to copy and paste a few things.

Part 4: Building Your Own Meditation App

More disclaimers time: this is, at its heart, building software. Software always comes with non-zero risks and though I’ve done my best to minimize them with clear instructions, there’s always the possibility that something goes astoundingly wrong. You waive any liability for astonishingly wrong consequences by doing this next part. And again, talk to your qualified healthcare provider first before making any changes to your health regimen.

First, think about things that relax you. If you have images from photo albums, grab 3 of them and put them in a folder on your desktop computer. We’ll call that folder meditation_app. If you don’t have any photos of things that relax you, go to the image generation service of your choice – Google Gemini, ChatGPT, Midjourney, Meta.ai, doesn’t matter.

You’ll prompt it with three fairly basic image generation prompts that specify subject, style, and format. You can use the Trust Insights Image Generator GPT for a more refined version or just rough it with this general format. Here’s an example.

Generate a photo of a tropical beach at sunset, with the waves gently brushing the shore. It’s summer, and the sky is filled with vibrant colors as the sun sets, a few low clouds in the distance. A small sailboat is visible near the horizon. There are a few palm trees at the edges of the photo. DSLR photo, 16:9 format, HD, 1920×1080.

Obviously, change the prompt to match whatever relaxes you. We want three distinct images, so do three different prompts – maybe it’s variations on the theme, like zooming in on the sailboat, or maybe it’s different themes entirely.

Save the photos in your meditation_app folder, sequentially named, like this: image1.jpg image2.jpg image3.jpg

You’ll want to download one more file, and that’s this very, very tiny MP3 file. Download it here and save it in your meditation_app folder.

It should look like this when you’re done:

Now that you’ve got your images, head to the most powerful reasoning model you have access to, such as OpenAI o1, Google Gemini 2 Flash Thinking, DeepSeek R1, etc. We’ll use the Trust Insights PRISM Framework again with these reasoning models.

Here’s the prompt.

You’re an expert in client-side JavaScript and HTML. Today, we need to build a basic web page with inline CSS and a client-side JavaScript. The overall purpose is to build a simple web-based meditation timer.
Here’s the details. The page will display a rotating series of three images, image1.jpg, image2.jpg, and image3.jpg. It will also have text on the page that tells the user to breathe in, to pause, and to breathe out. The timing for the sequence will be breathing in for 4 seconds, holding the breath for 7 seconds, and breathing out for 8 seconds. Image1.jpg will show during the breathing in, image2.jpg will show during the holding the breath, and image3.jpg will show during the breathing out.
There will be a single client-side JavaScript named meditation.js that the page, meditation.htm will reference. All styling should be in the page’s CSS; do not create a separate CSS file. The page’s background should be a neutral pastel color such as a calming green or blue. The text should be in a common, standard serif font at 18 point font size.
The loop runs forever; there’s no stopping point unless the user clicks on the image again. It just shows each image and the associated instructions in perpetuity until the user closes the web page tab in their browser.
When the user opens up the HTML page, there should be the first image and instructions for the user to click/tap the image to start the meditation. Listen for the click/tap and then begin the meditation when it’s received. There should also be a short note instructing the user that they can stop the meditation if they click the image again.
Show a progress bar beneath the image indicating the time to the next phase. The bar should start empty and fill up across the bottom of the image until it’s completely the size of the image. The bar should be 4 pixels high.
Add ARIA attributes to the HTML to ensure accessibility.
Play the bell.mp3 sound (stored locally) at each transition – breathing in, holding, and breathing out.
The images are in 16:9 format, and should be centered on the page with a resolution of 1280×720 pixels.
Produce the code for meditation.js, then produce the code for meditation.htm

Now, this is quite the beefy prompt, but what the AI of your choice should spit it is the code for two files. You don’t need to dig into the technicals (though you certainly can). What you do need to do is copy and paste the meditation.js output from AI into a plain text file named meditation.js, saving it to your meditation_app folder. Then repeat the process for meditation.htm, saving it in the same folder.

Once you’ve done that, drag the meditation.htm file to any open web browser and enjoy what you’ve built.

If you’re a developer, this is probably very mundane. But if you’re a non-technical person, and you’ve successfully copied and pasted the materials as is, chances are you’ve just built your very first app – congratulations.

Want to kick it up a notch? Perform steps 1-3 yourself and assemble a notebook of meditation and stress papers, then start having generative AI tools build you things like meditation scripts, voiceovers, and even music with tools like Eleven Labs and Suno. I did this recently for a friend who’s going through a rough patch, and it’s amazing how well it works once you start with solid data.

Part 5: Wrapping Up

There are a few lessons I wanted to impart in this week’s newsletter. First, amazing tools and capabilities exist now for us to do research, synthesize knowledge, and create informed, grounded outputs using generative AI. For any question we might have, we have the tools to gather the best possible answer, if we’re willing to put in the time and effort to get it.

That’s critical – generative AI makes it easy to accept fast, easy, but shallow answers. That might be fine for making social media posts for your brand, but when you’re talking about something vital like finance, law, or health, you owe it to yourself to gather and use the best data available.

Second, generative AI tools also give us the ability to turn knowledge into action (with appropriate supervision/subject matter expert consultation). We’ve heard the recommendations in our lives for the things we know we should do, but we’ve not taken action steps to bring that knowledge to life. As we saw with a very, very simple web app, it’s possible to do that now.

What’s powerful about the example I showed is how easy it is for you to customize it, to build it to your specifications and needs. That simple web page could have the images you care about, the sounds that you like, the wording and expressions that resonate best with you. There are no limits to what you can do with customizing it – and when you’re done, it’s uniquely yours, forever. There’s no monthly fee to pay, no service to rent, no information to give. You made it with your own AI capabilities, and there’s a tremendous amount of power in that.

Third, the world is changing fast. Things that were available yesterday might be gone tomorrow. In the USA, therapists and healthcare practitioners are in short supply, and demand is higher than ever. You can supplement the care you get with generative AI tools (with supervision!) to make what works best for you. Maybe your meditation app contains images of Tina Turner or Serena Williams. Whatever works for you, make it your own, and make the supplementary tools you need to succeed.

And this isn’t limited to a simple meditation app. This applies to anything. You could make your own cookbook, make your own music player, make anything that comes to mind where you might want to own yourdata. For example, if you have a functioning uterus and privacy concerns, maybe you make your own menstrual cycle tracker.

In my keynotes, one of the three pillars of success in the age of AI is whoever has the most, best ideas will win. We’re not talking just about business, but in every aspect of your life. If you’ve got an idea, you can bring it to life in some fashion with generative AI. The time to be fascinated with AI itself is drawing to a close. The time to be fascinated with what AI can do for you is just beginning, and I hope today’s issue opened up some new ideas for ways you can turn your own ideas into reality.

Whoever has the most, best ideas will win in the age of AI.

Mastering Prompt Engineering for Marketers is a 2 hour tour through prompt engineering. The first couple of modules walk through not just what prompting is, but what’s happening INSIDE the AI model as it processes a prompt. I made the explanation non-technical (because who really enjoys softmax layers and attention matrices besides me) but the walkthrough really digs into what’s going on inside the box.

Knowing that helps us understand WHY prompts do or don’t work. You’ll see why in the course, when you watch how a prompt is processed.

Then we walk through 3 prompt frameworks, plus “delve” 😏 into advanced prompting techniques, along with a downloadable guide of what each technique is, why you should care, when you should use it, and how to use it.

After that, we get into knowledge blocks and priming representations, then how to build and manage a prompt library.

What’s On My Mind: What’s My AI Tech Stack?

More than a few folks have asked what my AI tech stack looks like personally, and it’s an interesting question. One person asked for a peek behind the kimono, which is an expression I’d love to see get tossed on the bonfire because it displays profound cultural ignorance.

In Japanese culture, what’s under a kimono is… a lot more clothes. There’s a hadagi, which is more or less underwear, then a nagajuban, then the kimono, much in the same way you’d see someone’s sweatshirt, then regular shirt, then undershirt.

Anyway. Let’s talk tech stack.

Part 1: What is a Tech Stack, Anyway?

A tech stack is simply this: the toolbox of tools you use in your work. For AI, a tech stack is a bit misleading anyway – a stack implies some kind of order, from top to bottom. Things have a certain flow to them, and for me, that’s not how I use AI. Instead, AI is more like a palette that a painter uses, or a kitchen counter loaded up with appliances.

If I’m making steak, there’s no reason for me to fire up the blender for the steak. Blenders generally make terrible steak.

Okay, so what’s in my AI kitchen?

First, I have three different types of AI enablement. The first are preparatory tools. These are tools I use to process stuff before using it with the main application.

The second are the processing tools. This is what most people think of when they think of the AI tech stack, tools like Gemini or ChatGPT. These tools take inputs, process them, and turn them into outputs.

The third are the post-processing tools. These are AI-enabled apps that perform functions beyond what a language model or an image model can do. Think of tools like Opus Clips or Matchering that take a finished product and repurpose it or put some polish on it.

And then there are all the distribution points, which have their own AI that I have no control over. Think YouTube’s recommendation algorithm or LinkedIn’s People You May Know.

There are two other things you should know about me, because they’re relevant to how my AI kitchen is built. First, I’m kind of a cheapskate. I will generally prefer something free to something paid, especially when it comes to tech, because I know I can usually do as good a job as another tool. In the age of generative AI, this is doubly true.

Second, I’m kind of a tech libertarian. I believe in owning things. As much as I love the convenience of having any song available on your device or any movie you could want to watch streaming somewhere, I’m from a generation that still has ownership culture. I still have a binder of CDs in my basement. Because in a world where tech oligarchs decide what you can and can’t have, I enjoy thumbing my nose at them and owning my software as much as possible.

The downside of this perspective is that what I have takes a lot more thought and maintenance. The upside is that I never have to worry that if my credit card stops working, so does every digital service I own. Those are my biases, and you should understand that my tech stack is built with that lens.

Part 2: Preparatory Tools

This is the bread and butter for me, and many of these tools are home-grown because I either couldn’t find a tool that did what I wanted, or I could find it and couldn’t figure out why I’d spend hundreds of dollars a month in subscription fees for a tool that I could make on my own.

What are they?
– SQLite. This free, open source database platform is, for me, the best way to store data, especially AI-generated or AI-processed data. It’s all local files, no server, no cloud, just data in a common format.
– VSCodium with Cline: My favorite development environment. This is an open source version of Microsoft’s VS Code, minus all of Microsoft’s surveillance technologies. It’s compatible with every VS Code extension.
– Brave: This Chromium compatible browser has privacy baked into it at every turn. It’s free, open source, runs all Chrome extensions, and blocks all kinds of tracking.
– Thunderbird: This free, open-source email client stores all its messages in both SQLite tables and Unix MBOX formats. Believe it or not, this matters – if you want to process email at scale, this is the best way to do it. You download all your messages onto your machine in Thunderbird, and then just process the MBOX files locally. No API calls, no waiting, no internet needed once you have the messages downloaded.
– NordVPN: This is my VPN that I use when I want to use a VPN to access stuff I’d rather not have people watching. I like that I can change endpoints quickly and easily.
– Python: I don’t love Python, but it’s the lingua franca of the AI world. Every generative AI tool speaks Python, and speaks it well, so it’s generally the best choice for coding if you want generative AI to do most of the lifting.
– R and R Studio: This is my favorite. R is a data science and statistics programming language and is incredibly efficient, has great libraries, and thinks statistics natively.
– Audio Hijack: This is the tool I use to record local audio on my Mac, regardless of application. I have this running any time I’m speaking on webinars and podcasts, because I like to have a local copy of what I say. For privacy’s sake, I record just my end.
– OBS Studio: When it’s just me filming, this is the video recording tool I use. It’s free, open source, powerful, it records locally (no cloud, so no uploading or downloading), and it can also stream.
– Joplin: This is the note-keeping tool I live in. Free, open source, syncs across devices, and works in Markdown natively.
– yt-dlp: A free, open source Python app that downloads YouTube videos, audio, and captions files.
– Whisper.cpp: This is free, open source voice transcription software which I use with the Distil-Whisper model for accurate, high-speed, free, local transcription. This is great for any audio with one speaker or where you don’t care if speakers aren’t noted.
– Aider Chat: This is free, open source command line pair programming. It’s an incredible utility.
– ffmpeg: Free, open-source video and audio converter that can convert just about anything to anything.
– Pandoc: free, open-source document converter that can also convert almost anything to anything

You’ll note, appropriately, that most of these tools are tools that generate data. I have a pile of custom tools I’ve built, a few of which include:

• Article scraper: given a list of URLs, it uses Python and a few common Python libraries to scrape the articles, remove ads and navigation, and save the main text in text or Markdown formats.
• Website converter: given a folder full of HTML, it uses Python and Markdown and converts all the web pages to plain text.
• VTT processor: given a folder full of VTT captions files (the YouTube default format) this converts them to plain text that’s way more readable.
• Reddit grabber: given a subreddit and the number of days, this Python code grabs the posts and replies from the subreddit, using the Reddit API.

Part 3: Processing Tools

Now for the main event, the generative AI tools I use.

For local AI, there are two different servers I’ll use.
– LM Studio: When I need something fast, LM Studio (free, but not open source) can natively load MLX models (Mac native) which are 3-5% faster than models not optimized for the Mac.
– Koboldcpp: For storytelling, fiction, and roleplay, this is the server I use because it’s well designed for more creative model use.
– SillyTavern: For roleplay (like virtual focus groups), there is no better tool. It requires either LM Studio, Koboldcpp, or API access to the AI of your choice.
– AnythingLLM: The best all around interface for local AI usage.
– Mistral Small 3: This is my day to day local AI model. It’s fast, capable, and smart.
– Deepseek R1 Distill Llama 70B: This is my heavy duty model when I need more knowledge and precision as well as some reasoning capabilities locally.
– Qwen2.5 Coder: Still the best local model for writing code. Best used in a coding environment.
– ComfyUI: free, open-source image generation that, with the right models, is incredibly powerful. Steep learning curve.
– Black Forest Labs Flux-1 Dev: hands down, one of the best image generation models around and it’s free and open weights, so you can generate high quality images on your local machine if it’s beefy enough.

For cloud AI, I have a bunch of different preferred choices.
– NotebookLM: hands down the best retrieval augmented generation (RAG) tool there is when you need to minimize the risk of hallucination. Now powered by Gemini 2 Flash.
– Google AI Studio: my preferred generative AI interface, because it gives administrative access to their models and you can do things like turn the safeties off.
– Gemini 2 Flash Thinking: Google’s best reasoning model and quickly becoming my default. They did a really solid job with its reasoning.
– Gemini 2 Pro: their best standard model for tasks where you want to provide your own chain of thought.
– Google Vertex AI: When you want to build inside Google Cloud, Vertex is the place to do it. Access to all of Google’s cutting edge models, governed by your Google Cloud account’s privacy and security.
– IBM WatsonX: When you need the security of IBM with the flexibility of open weights models, WatsonX is the place to go.
– Anthropic Claude: for precision coding and use cases where you need thorough instruction following, Claude is the best.
– Deepseek R1: currently the chart topping open model, now available on multiple hosts around the world in privacy-friendly services
– ChatGPT: my least favorite cloud service; compared to other providers, their models perform not as well (example: DALL-E is far less capable than Flux-1 on the same prompts, the new o3-mini is terrible quality compared to Deepseek, etc.), but their GPTs are nice for distributing ideas.

Part 4: Post-Processing Tools

• Opus Clips: still the best long-to-short video splicing tool out there.
• Fireflies.ai: A great transcription tool when you need to diarize (separate and denote) speakers in multi-speaker audio.
• Matchering: an incredible Python library that, given reference audio, will level a target file with the same mastering as the reference audio. So useful for AI-generated songs that are mastered to sound like boring garbage.
• Suno: Crazy good song generation software. I use it a lot for fun stuff. It ain’t gonna win a Grammy any time soon.

And a couple of things I’ve made:
– Google Speech Reader: given a text file, it chooses between Google Text to Speech (the default) or Eleven Labs and makes audio files out of text.
– Video Visualizer: I didn’t want to pay for Headliner any more so I wrote my own in Python. Takes in audio, spits out a cheesy visualization in video.
– Email list cleaner: given a list of addresses that fail validation, this LLM-based tool tries to figure out if the user just fat fingered something (hello, all of you [email protected], I see you) and repair it.

Part 5: A Cautionary Tale

As much as people love buffet lists like this of all the tools, this is like having a tour of Emeril’s kitchen and seeing all the appliances. None of the ingredients are here. None of the recipes are here. None of the people who work in the kitchen are here. This is just the appliances list, and while that can be handy, the appliances don’t add much value if you have no ingredients, no recipes, and no skills.

Second, this list changes like, weekly. As technology changes, I swap things in and out all the time. It will not be current for very long, but I hope it gives you a taste, more than anything, for how I think about the tools I use. I lean heavily towards things I can own, things I can control, things that work with as few dependencies on other companies as possible.

If the big AI tech companies went out of business tomorrow, what would I still have? I’d still have a huge suite of AI tools – Flux 1 for images, R1 for chat, Qwen for coding. I’d still have almost all the foundational tools I have now, and that’s super important to me.

As the world becomes more and more uncertain, knowing that you have backups for things that are mission critical isn’t just important, it’s what helps you sleep at night.

Mastering Prompt Engineering for Marketers is a 2 hour tour through prompt engineering. The first couple of modules walk through not just what prompting is, but what’s happening INSIDE the AI model as it processes a prompt. I made the explanation non-technical (because who really enjoys softmax layers and attention matrices besides me) but the walkthrough really digs into what’s going on inside the box.

Knowing that helps us understand WHY prompts do or don’t work. You’ll see why in the course, when you watch how a prompt is processed.

Then we walk through 3 prompt frameworks, plus “delve” 😏 into advanced prompting techniques, along with a downloadable guide of what each technique is, why you should care, when you should use it, and how to use it.

After that, we get into knowledge blocks and priming representations, then how to build and manage a prompt library.

What’s On My Mind: The State of the State of the Art of AI

Over the last week, I’ve seen a number of incredibly poorly-thought hot takes on models and AI systems like Deepseek, Qwen, and others. So I figured it’s time for us to do a little EPCOT-style State of the State of the Art.

For those unfamiliar, EPCOT (The Experimental Prototype Community of Tomorrow) is a part of Walt Disney World. It’s an American amusement park that has Americanized vignettes called pavilions of 11 nations – Canada, the UK, France, Morocco, Japan, the US, Italy, Germany, China, Norway, and Mexico – and Americans can see oversimplified versions of other national foods and cultures in a relatively short 2 kilometer walk.

In that spirit, we’ll take a walk around the world of AI, looking at the models that perform well on leaderboards.

Part 1: Why Leaderboards Matter

There are tons and tons of benchmarks for AI models, all with cryptic-sounding names like MMLU (Massive Multitask Language Understanding) and GPQA (General Purpose Question Answering). For years, AI model makers have put their models to the test with these benchmarks, showcasing how those models score. Every company aims to top the charts as best as they can.

However, one of the challenges with these benchmarks is that there’s incentive to cheat – to train the models specifically on the test data so they perform well on the test. This is the AI equivalent of “teaching to the test”, a common criticism of standardized testing in education. AI model makers want to look the best in front of their peers, and some have gotten in some hot water about what’s fundamentally academic dishonesty, peeking at the test questions in advance. (OpenAI famously got in trouble for their o3 model because they helped design and train the test their model was evaluated on)

The leaderboard that most folks pay attention to is LM Arena, a board where users can put in a prompt and are given two sets of results. They evaluate the results based on how well each model – whose name is withheld – answers the question.

For example, I might give it a complex prompt about Google Ads.

I’d then evaluate which response was better.

To do the evaluation, I’d obviously need to have some level of subject matter expertise in the response. Once I vote, then the model names are revealed, like a blind taste test. (remember those old Coke/Pepsi ads from the 80s and 90s? this is just like that, but less refreshing and lower in calories)

LM Arena is one of the favorites for judging AI model performance because it’s human-based, with real people voting and putting in real prompts. Obviously, you can see how this could also be manipulated, but for now it’s one of the best leaderboards for general use.

There are also lots of leaderboards and sites for specific use cases, from writing to medicine to math. For the purposes of our walk around an AI EPCOT of sorts, we’ll tour through LM Arena’s leaderboards.

Part 2: The State of the Art World Tour

So, with that background, let’s look at the leaderboard.

Well, that was a short world tour, wasn’t it? The top models, based on human feedback from around the world, are from the USA and China. We’re apparently eating McDonalds or Laoxiangji.

As an aside, this is why Deepseek is SUCH a big deal. How many of the top 10 AI models on the leaderboard can you download? Only Deepseek. If you’re a nation that doesn’t have cutting edge AI capabilities, and you want to ensure you’re competitive without paying a lot of money to a company in another nation, Deepseek suddenly gives your nation state of the art capabilities that are under your control. You can download and run Deepseek on your own servers, within your own networks, and enjoy its capabilities.

So if the leaderboards aren’t helpful, then we’ll just take a stroll around the world ourselves, to see what companies are leading in their respective regions outside the USA. No one really needs to be told where Silicon Valley is.

Our first stop is Canada, where Cohere is headquarted. Cohere is the maker of the Command R family of models. For folks without a ton of compute resources, Cohere’s models are considered some of the most efficient.

After Canada, get on a flight to London where Stability AI is based. Stability AI is the maker of the Stable Diffusion family of image generation models, long the preferred tool of choice in the open weights image AI world.

Hop on the train and go under the channel to arrive in Paris and the Mistral family of models. Mistral just released Mistral Small 3, a very efficient and smart model that runs on small hardware. Mistral is the darling of the EU, and their models work very, very well.

A short train ride later, we arrive in Freiburg, Germany, home to Black Forest Labs. Their Flux family of models are widely considered to be the best open image generation models on the market.

Head south to Tel Aviv, where AI21 Labs in Tel Aviv has created Jurassic-2 and Jamba, both language models. Jamba in particular is an interesting model as it blends different architectures together – structured state models and transformers, one of the first of its kind.

Fly further south to the United Arab Emirates and their Technology Innovation Institute. There in Abu Dhabi, they’ve released the Falcon family of models with Falcon 2. Falcon 2 VLM is best known for its efficient vision to language conversion for things like image captions.

Keep heading south and you end up in Johannesburg, South Africa, home to Lelapa AI and its Vulavula models. Vulavula speaks English, Afrikaans, isiZulu, isiXhosa, Yoruba, Swahili, Sesostho, and other sub-Saharan languages natively, making it one of the premier AI companies in Africa.

Head east to Singapore and the AI Singapore organization. AI Singapore makes SEA-LION, an LLM specializing in Southeast Asian languages such as Thai, Vietnamese, Tamil, Burmese, Khmer, Filipino, Malay, Indonesian, and so many others.

Fly north to Hangzhou, China, the home of Alibaba Cloud. Alibaba makes the best-in-class Qwen models, including the recently released Qwen2.5-VL and Qwen2.5 Max that outperform many competitors. Qwen2.5 Coder is considered one of the best coding models in the world, and it’s small enough to run locally on developer laptops.

Take a train from Hangzhou to Beijing, home of Deepseek itself. It really needs no other introduction, so get a plane and head for Seoul, South Korea. LG, the electronics company, in addition to making affordable and reliable appliances, also makes EXAONE 3.5, their state of the art model. EXAONE’s performance is especially good on their tiny 2.4B model, which makes sense as LG makes a ton of mobile and smart devices; having an LLM that can be embedded in their devices would make them smarter without relying on massive data centers.

Get on another plane and fly to Tokyo, where Fujitsu’s Fugaku LLM specializes in state of the art Japanese language. Fugaku’s an interesting model in that it’s made using CPU compute instead of GPUs; with a global shortage of compute power, Fujitsu decided to make models with the hardware they already had, to good effect.

What we see from this EPCOT-like world tour of generative AI is that despite the headlines, companies around the world are innovating in generative AI. Even if Silicon Valley vanished tomorrow, the technology itself has matured enough that many different nations are pursuing their own state of the art models, especially models localized for their regions.

Part 3: Why Do We Care?

Why do we care about the rest of the world when the leaderboard tells us what models are topping the charts? Well, there’s three primary reasons.

First, a model that’s generally good at everything may not be very good at specific things. If I’m going to do business in, say, Seoul, chances are EXAONE from LG is going to do a better job with Korean than Google Gemini, just because more of the training data is specifically Korean. If I need to do business in South Africa, Vulavula is probably more proficient at Xhosa than ChatGPT.

Second, a model that’s gigantic isn’t always the best choice. Yes, in general, the bigger a model is, the better it performs on most tasks. However, smaller, focused models can beat bigger state of the art ones on speed because they’re so compact. A model like Mistral Small or Deepseek’s Distil-R1 can be exactly what I need, especially if I want to run it on my own equipment for the cost of energy only.

As AI matures, sustainability – i.e. not consuming ridiculous quantities of fresh water and electricity – will become more and more important. Smaller, more nimble, more resource efficient models will be the best choice for many companies that want to balance state of the art performance with responsible, environmentally sound compute practices. Half of my personal AI usage is done on local models running on my MacBook, which consumes a maximum of 140 watts of power.

Finally, global competition is a great thing. It prevents any one company or any one country from achieving dominance in AI. We never want a foundational technology to be under anyone’s sole control. Today’s Old Republic could be tomorrow’s Empire, and no one wants to see Emperor Palpatine running all the AI.

People have rightly pointed out that different models have different biases; Google’s Gemini in the consumer portal will absolutely refuse to answer any questions about USA politics. China’s Deepseek won’t answer questions about things like Tiananmen Square. Like humans, every AI has biases, and like humans, having more options to consult means we can work around the biases of any one given model.

The more variety we have, the more diversity we have in AI, the more capability we have as consumers and users of AI. A recent article in the Times of India urged the country to get into the generative AI race as well; Deepseek proved that a nation could build a state of the art model without massive amounts of money required. The next time we walk around the EPCOT of AI, I hope we stop in Jaipur or Hyderabad or Mumbai as well.

For you and I, what this all means is we have options. We have a bounty of riches, an embarrassment of riches when it comes to using generative AI. If we step outside the mainstream media and Silicon Valley’s hype cycle, we’ll see that generative AI options abound in more and more places, which is better for everyone. The next AI app you build at your company could use Mistral or Qwen, now that you know about them, and could save you considerable amounts of money.

What’s On My Mind: Introduction to Reasoning AI Models

This week, let’s talk about reasoning models, as they’re all the rage at the moment. What is a reasoning model? How is it different from regular AI? Why do we care? We’ll answer all this and then some, so buckle your seat belt, unplug the popcorn machine, and let’s get started.

The Age of Reason

“c. 1400, resounen, “to question (someone),” also “to challenge,” from Old French resoner”

AI – language models in particular – perform better the more they talk, like sportscasters and YouTubers. We discussed why this is the case in a previous issue, but the very short version is that the more they talk, the more they can zero in on the right answer. The statistical nature of a language model is that the more talking there is, the more relevant words there are to correctly guess the next word.

For most of the first two years of generative AI, AI models relied on us to tell them to talk more. For anyone who’s been using generative AI for longer than a hot minute, you probably know one of the foundation princples of prompting: chain of thought. This is when we tell the model to think step by step, or explain things step by step.

This works, of course, by getting the model to say more relevant words.

Another foundational principle that you’ve probably learned (and if you haven’t, sign up for my new paid course, Mastering Prompt Engineering for Marketers) is reflection prompting, where we tell a model to take a step back and think things over. We do this when it’s not getting the point.

And a third principle is the reward function. You’ll see this written out often in the form of things like scores, scorecards, etc. where we ask AI models to score their efforts, or to keep a running score of things they’ve done well or poorly.

These three core components – chain of thought, reflection, and reward functions – have been part of prompt engineers’ toolkits almost since the beginning of generative AI, and certainly once advanced models like GPT-4 came out at the end of 2023.

Yet most people don’t use them. Most people don’t even know they exist, despite how much of an impact they make on model performance and the results they generate.

So what companies like OpenAI, Alibaba Cloud, Google, and Deepseek figured out was to make models do this automatically – thus creating a class of language models called reasoning models.

Reasoning models fit the etymology of reason perfectly – they question and challenge themselves. Is this the right idea? Is this what the user wants? Are we getting closer to the stated purpose or not? What should we do to achieve the tasks the user has set out for us?

Here’s a key thing to remember, however. Reasoning models are still transformers-based, attention-based large language models. Even though they display impressive capabilities at self-reflection and self-correction, even though we may anthropomorphize them as they work, they are still fundamentally the same architecture as we’ve been using all along. The basic rules haven’t changed, rules like using more relevant, specific words in our prompts.

Why Reason?

Reasoning models are important because so many of us don’t do any reasoning of our own when we use generative AI. We collectively tend to treat generative AI like it’s a genie from fairy tales, that it can somehow magically read our minds and create what we want without us having to work very hard to be specific.

Model makers realized that, two years into the Intelligence Revolution, people are still feeding them prompts like “Write a blog post about B2B marketing and make it interesting” (I kid you not, I saw someone actually do that) – and still getting generic, low quality outputs. The more people who use generative AI badly, the harder it is for the technology as a whole to get traction.

Hence, model makers have spent heavily building reasoning models to try patching what’s fundamentally a human flaw. A reasoning model in general will give better, higher quality answers to questions than a non-reasoning model, especially if the initial prompt isn’t terribly robust.

For us in our day to day jobs, reasoning models are a great choice for complex tasks. They’re not a great choice for simple tasks because they’re incredibly compute intensive; if you’re worried about sustainability, reasoning models consume anywhere from 2x – 10x the power and resources per query of non-reasoning models.

We can see this in charts like this one from Artificial Analysis:

• OpenAI o1 cost per 1M tokens: $26.25
• OpenAI GPT-4o cost per 1M tokens: $4.38
• Deepseek R1 cost per 1M tokens: $2.88
• Deepseek V3 cost per 1M tokens: $0.90

Incidentally, this chart is why all the big AI tech vendors in the West are in a panic this week. Deepseek’s models are top tier in performance while being bargain basement in terms of cost, and are freely available to download if you have the infrastructure to support them. Deepseek’s reasoning model is 48% less expensive than OpenAI’s non-reasoning model, and 89% less expensive than their reasoning model.

So what’s a simple or complex task? If we go back to the core use case categories of generative AI, tasks like summarization, extracting, rewriting, and classification tend to be relatively simple tasks. A prompt like “summarize this email’s key points” is a task that even the least powerful AI models are quite capable of handling. Using a reasoning model on this task would be overkill.

On the other hand, if we ask a model to take in a big pile of information and build a SWOT analysis, then recommend a business strategy from that? That’s definitely a reasoning task. It’s complex, multi-step, and requires a lot of thinking.

How Do We Start Reasoning?

Once we’ve figured out whether a task is a reasoning task or not, we then have to start prompting the reasoning model. Reasoning model prompts are different than regular AI prompts; critically, things like “think about this step by step” should be absent because the model already knows to do that.

Last week, I introduced the PRISM model for reasoning prompts, which goes like this:

• Problem (or purpose): state what it is you’re trying to achieve
• Relevant Information: give lots of context, background information, etc. to help the reasoning model know what it’s doing
• Success Measures: what does success look like, and how does the model know it’s succeeded?

In many ways, this is the front half of the Trust Insights RAPPEL framework; but instead of us having to do the step by step thinking, the model does that part.

I compare reasoning models and non-reasoning models like this. A non-reasoning model is like the world’s smartest, most forgetful intern. You need to provide a ton of information, explain the task and how to do it clearly, and guide it. A reasoning model is like the world’s smartest, most forgetful junior manager. They don’t need to be told how to do a task – they figure that part out for themselves. But they absolutely still need robust amounts of information about what they’re doing, why they’re doing it, and how to know when they’ve succeeded.

Let’s look at a couple of examples of how a non-reasoning versus a reasoning prompt might look.

A non-reasoning prompt might go like this: “Role: You’re a world-famous email marketing expert.

Action: Today, you’ll be writing a 500 word blog post on the importance of deliverability protocols like SPF, DKIM, DMARC, and BIMI in email marketing.

Prime: First, answer these questions:
– What are best practices for implementation of SPF, DKIM, DMARC, and BIMI? Talk this through, step by step.
– What are common mistakes made by less experienced email marketers when it comes to delivery protocols? Talk this through, step by step.
– What are expert tips and tricks for implementing email deliverability protocols? Talk this through, step by step.

Prompt: Then start drafting the article. Talk about what each protocol is, why it matters to the marketer, and how they should get started. Be clear and include examples and analogies so that people don’t get confused. Use only one bulleted list in your response, and only if it’s appropriate.”

What would the same prompt look like for a reasoning model?

“Problem: Marketers are getting stuck in spam because their email marketing hasn’t implemented deliverability protocols.

Relevant Information: You’re a world-famous email marketing expert. Today, you’ll be writing a 500 word blog post on the importance of deliverability protocols like SPF, DKIM, DMARC, and BIMI in email marketing. Explore best practices, common mistakes, and expert tips for deliverability protocols. Talk about what each protocol is, why it matters to the marketer, and how to get started.

Success Measures: Your blog post should be 500 words, +/- 2%. Your post should be in non-technical, action-oriented language to help the reader know what to do after they’ve read the blog post. Be clear and include examples and analogies so people don’t get confused. Use only one bulleted list in your response if appropriate.”

Can you see the difference? There’s much less “do this, then this” in the reasoning prompt. It’s guidance that you would give a junior manager, not an intern – the manager will figure out how to make it happen, but you need to tell the manager what needs to be done, why, and what success looks like.

Here’s your homework assignment. In the model of your choice – Gemini Flash 2 and Flash 2 Thinking, Deepseek V3 and R1, OpenAI GPT-4o and o1 – test these two prompts for yourself. See what the output looks like from each non-reasoning and reasoning model, along with the way the models think aloud.

Then do this for some of your favorite prompts. See how they each run in comparable reasoning and non-reasoning models to see the difference.

Wrapping Up: Reason is the Foundation

In general, for the same complex task, reasoning models perform better than non-reasoning models – and the three state of the the art foundation models on the market right now, OpenAI o1, Gemini Flash 2 Thinking, and Deepseek R1 – all behave differently. They have very different infrastructure and their models were assembled differently. (for the uber-technical, it’s assumed o1 is a dense model, whereas Gemini and R1 are MoEs, and R1 was trained almost exclusively with RL whereas the others are assumed to be SFT trained)

What are the kinds of tasks you’d hand to a reasoning model? Again, think about the intern versus junior manager analogy. There are some tasks you can confidently hand to the intern. There are other tasks you’d probably prefer to hand to someone a little more experienced. Whatever those tasks are, that’s how to divide them up. Having the intern transcribe and summarize is a good fit. Having the intern anaylze the psychographics of your ideal customer is less of a good fit than handing that to someone more senior.

And reasoning models are a powerful fit for the next generation of AI agents. This week, I built a clone of OpenAI’s Operator using the Browser Use library in Python, combined with Google’s Gemini 2 Flash Thinking. Having an AI agent that can control a browser is powerful and compelling – but it needs a heavy duty AI model on the back end that can think things through, especially when dealing with complicated user interfaces like websites.

Once you understand what reasoning models can do and how powerful they are, you’ll be well on your way to harnessing their power for complex tasks.

What’s On My Mind: A Semi-Technical Deep Dive into AI Language Models

This week, let’s do a very deep dive into the technical guts of generative AI, specifically large language models. To make AI work optimally, it helps to understand at least a few of the concepts, so we understand why they do what they do.

Part 1: Tokens

Generative AI begins with tokens. LOL already with the technobabble.

What’s a token? It’s a unit of information that the AI uses to learn and generate text. Think of it like ingredients in a recipe. If you want to understand how to make a cake, you need to know what goes into it: flour, sugar, eggs, and so on. Similarly, to understand language, AI needs to break it down into its basic components: tokens.

Now, you might think that the simplest way to break down a word is into individual letters, like s-t-r-a-w-b-e-r-r-y. That’s called character-level tokenization. But for large language models, that’s like chopping your cake ingredients into individual molecules. It’s too granular, and it makes it hard for the AI to see the bigger picture. Imagine trying to figure out how to combine different molecules of flour, sugar, butter, etc., to make a cake. It would be very difficult, as there are so many combinations.

On the other hand, you could just treat each whole word as a single ingredient, like “strawberry.” That’s called word-level tokenization. But that’s like having a separate ingredient for every possible cake variation: strawberry cake, chocolate strawberry cake, gluten-free strawberry cake. You’d end up with a gigantic recipe book, and you’d have trouble with new types of cake you’ve never seen before, also known as out-of-vocabulary words. What if someone asked for a “strawberry-rhubarb” cake and that wasn’t in your recipe book?

So, AI model makers use something in between, called subword tokenization. It’s like having ingredients for common parts of cakes, like “straw,” “berry,” “chocolate,” and “cake.” This way, the AI can handle words it’s never seen before by breaking them down into familiar parts. The most common type of subword tokenization is called Byte Pair Encoding, or BPE for short. Another popular one is called WordPiece. These algorithms are a bit like a master chef who knows how to combine ingredients in the most efficient way. They look at massive amounts of text and figure out the best way to split words into subword units. These algorithms also help keep the vocabulary, or all the possible ingredients an AI can use, to a manageable size.

For example, using BPE or WordPiece, the word “strawberry” might be split into “straw” and “berry.” Or it might stay as a single token if it’s used very often. It all depends on how often different combinations of letters appear in the text the AI learns from.

This is why, by the way, AI often has trouble telling you how many Rs are in the word “strawberry”. You might think it’s because “strawberry” is chopped up into “straw” and “berry” but that’s not quite right. It’s more like asking a chef to tell you how many molecules of carbon are in a cake. They could probably figure it out, but that’s not really what they’re trained to do. Similarly, AI models are trained to understand and generate language based on the relationships between tokens, not to count individual letters. They see the cake, or in this case the word, as a whole, delicious thing, not a collection of individual atoms.

Who wants cake now?

Why go through all this trouble? Because tokens are the fundamental building blocks of language for AI. By breaking down text into tokens, AI can start to understand the relationships between words and how they fit together to create meaning. Each token will be assigned a number.

Part 2: Vectors and Embeddings

Once a model maker tokenizes a text, converting every word and bit of punctuation into numbers, they then have to convert those numbers into vectors and embeddings.

Think of it like this: imagine a special app called “Google Language Maps.” In this app, every word is a location on the map, and its meaning is determined by its coordinates, just like latitude and longitude in the real Google Maps. If you search for “Starbucks” in Google Language Maps, what do you expect to find nearby? Probably other coffee shops, maybe a few tea places, perhaps some bakeries. You have an intuitive sense of what locations are close to “Starbucks” on this language map.

Imagine the area around “Starbucks” in Google Language Maps. What are all the other points of interest (POIs) that might be close by? When AI model makers make models, they take all those tokens and plot them on a giant, multi-dimensional map, kind of like the one in Google Language Maps. Words with similar meanings, like different coffee shops, end up close to each other. Each word is assigned a set of coordinates, called an embedding, which tells the model exactly where it is on the map.

Now, here’s where it gets interesting. Just like Google Maps can adjust your route based on traffic, the meaning of a word can change depending on the context. So in our Google Language Maps app, if you have a paragraph talking about things like jasmine, oolong, or matcha, and then you type Starbucks a paragraph later, the AI model is more likely to suggest the word tea than coffee. Even though the word coffee is most strongly associated with Starbucks, the words jasmine, oolong, and matcha are more related to tea. So, in this case, it’s like Google Language Maps rerouting you. Even though your usual route to “Starbucks” might pass by a bunch of coffee shops, if the context is all about tea, the model will adjust the “route” to “Starbucks,” making “tea” the closer and more relevant destination. It will calculate a slightly different route, or a slightly different set of coordinates, for that particular instance of Starbucks.

Conceptually, if you think about every word having a location on this giant Google Language Map, and how those locations can be adjusted slightly by the surrounding words, like a route being adjusted, then you’re starting to get a general idea of what vectors and embeddings are. Embeddings are a numerical way of representing where words are located on the map and how they relate to each other. It’s like the coordinates and distances that Google Language Maps uses to calculate the best “route” between two words. Those relationships, those coordinates and distances, are what allow large language models to understand and generate human language.

It’s worth pointing out here that this process, vectorization and embedding, is why generative AI can’t do math. Mathematics – computing operations like addition, subtraction, multiplication, division, and all forms of calculation – don’t operate based on what numbers are nearby. Asking generative AI to do math is like asking a blender to fry a steak, or asking for sushi at a Starbucks. That’s just not what it does. Now that you know how vectorization and embedding work, conceptually, you can see why generative AI language models shouldn’t be doing math.

Part 3: The Attention Mechanism

Now, let’s move onto the heart and soul of today’s generative AI: the attention mechanism. Introduced in 2017 by researchers at Google, the attention mechanism is a novel way of predicting tokens. For us marketers, most of the time, that’s words.

Prior to 2017, there were plenty of ways that machines tried to predict words. You’ve enjoyed that experience for years, with autocomplete on your phone and similar predictive mechanisms. These older models had a very narrow, very incomplete memory that relied on different techniques than the attention mechanism, meaning they would successfully predict words you used frequently and recently (mostly, lots of people still find their phones autocorrect to ”duck this ship”) but they couldn’t “remember” or process more than a couple of words back.

The attention mechanism is different. It allows the model to consider a large amount of text when making predictions, not just the few words immediately preceding. From the very first word you type to what the AI says, every word that appears on screen can be taken into account. Modern AI like Google Gemini can remember up to 2 million tokens, or about 1.5 million words, in a conversation.

Let me say that again because it’s really, really important.

Every word that appears on screen can be taken into account when the AI is predicting the next word. But, not every word is equally important. The attention mechanism allows the model to decide which words are most relevant to the prediction it’s making right now.

Here’s an example of how this works. If you’re old enough, you probably remember a series of kids’ books called Choose Your Own Adventure. In those books, you’d start out at the very beginning, and you’d choose the next page to go to based on the story you wanted to read. Each page would have multiple choices, and that would eventually end up telling a complete story. And you could go back, re-read, and make different choices and end up reading a functionally different story.

That’s kind of how attention models work, but with an important difference. Instead of choosing a whole page, the model predicts one token (usually a word or part of a word) at a time. Think of each token as a single plot point in our story. The attention mechanism helps the model decide which previous plot points (or tokens) are most important for predicting the next one. Every choice, every prediction, influences the next choice, and those choices are cumulative, just like in a Choose Your Own Adventure book. Instead of predicting every page of the story, the attention model is choosing a new token at the end of every previous one, assembling the story bit by bit instead of page by page.

This is critically different than older forms of AI because the attention mechanism can remember (something called a context window) a ton of information. Modern AI like Google Gemini can remember up to 2 million tokens, or about 1.5 million words, in a conversation. What you write at the beginning of the chat influences the words being predicted a hundred thousand words later.

This is also why being specific with our language matters so much. The more irrelevant words or junk we put into a chat with AI, the more those words throw off future predictions, making them less accurate. It’s like trying to force plot points into our story that don’t quite fit.

This is ALSO why generative AI, when naively prompted, tends to spit out boring, uninspiring slop. It’s predicting based on a very general set of plot points and thus guessing the most probable next words with no additional guidance. Highly probable text is generally not highly exciting text to read, nor is it unique.

Something I say in my keynote talks is that the more relevant, specific words (especially jargon) you use in prompts, the better AI will perform. It’s like giving the model more interesting and specific plot points to work with. It’s why so many prompting frameworks ask you to be specific and verbose.

Here’s another general rule of thumb, now that you understand the attention mechanism. Remember that every word on screen can influence the next prediction, but some words have more influence than others. If you ask a generative AI model what it knows about a topic and get it to respond with correct knowledge, then the next prompt you type will take into account all that background information you invoked, making the results better. You’re essentially providing more relevant plot points for the model to consider.

The more AI has a chance to talk, to step through things, to go step by step, bit by bit, the better it tends to perform. When we look at prompt engineering as a discipline, more than half of the techniques are in the chain of thought family, which is fancy for “talk this out step by step”. This works because of the attention mechanism – the more a model talks, the more relevant words go into the context window, increasing the accuracy of predicting the next word. Each step provides more plot points, making the overall story more coherent and detailed.

Part 4: Putting the Pieces Together

With everything we’ve discussed so far, let’s start putting together the big picture so you can take practical steps towards improving your AI usage.

What we’ve covered so far: models are made from training data, turned into tokens which are then turned into statistical relationships of words, phrases, topics, and concepts. Generally speaking, a model will return results that are statistically close to what we prompt it with.

Thus, if we want to get the most out of generative AI, we have to understand that these distributions, these statistical relationships, are how models make decisions. If we don’t like the decisions they’re making, we need to change how it makes those decisions. We do that with lots of specific directions, examples, asking it to think aloud, asking it to go step by step, and giving it guidance.

I created the Trust Insights RAPPEL Framework to accomplish that in a relatively easy way to remember. RAPPEL stands for:

• Role: telling the model who it is with specifics and jargon. This invokes statistically related terms, and the more jargon, the better. The more specific, the better, because the model will match up our role statements with information it’s seen in the past.
• Action: telling the model at a high level what task you want it to perform. This helps guide the overall output by introducing the goal early on. We won’t necessarily provide a lot of detail here, but we want to set the goal down early to steer and influence future predictions.
• Prime: telling the model to spit out what it knows on a topic, or uploading our own data here if we have very specific information we want the model to use. This background information fills the model’s memory with lots of relevant words and concepts, helping further reinforce the direction we want it to go. Imagine in the Choose Your Own Adventure book instead of a short introductory paragraph before the first decision, you provide, like, a 40 page story. By the time the reader has read through that story, they have much more information to make the next choice with.
• Prompt: telling the model what to do. This is the actual prompt, the instructions for what we want the model to do. By this point, the model’s working memory is so full of knowledge that even a relatively generic prompt like “Now write an article about B2B marketing best practices” will deliver great results because we’ve spent a lot of time loading up the model with that knowledge.
• Evaluate: telling the model what it did well or wrong. This step helps correct the model’s outputs and refine them.
• Learn: telling the model to build system instructions or prompts from the conversation. We use the attention mechanism and the context window to distill down the most important parts of the conversation into a prompt we can reuse for the next time we need to accomplish the task.

Behind the scenes, the RAPPEL framework is using a bunch of well-researched techniques from a variety of academic papers I’ve read on prompt engineering, and taking into account the underlying mechanisms of the attention mechanism and the way generative AI works.

For example, the role is a technique called role prompting. Consider two articles, one written by an expert and one written by a drunk on Reddit. With a naive prompt like “write a blog post on email marketing”, a model would look into its long term memory and find all the associations with those words – including both sources. When models are made, there’s no weighting to say “this academic paper should be given greater consideration than the drunk dude’s Reddit shitposts”. The text is weighted based on volume, not authority.

The action and prompt are a technique called reinforcement prompting. The more you repeat specific instructions, the more weight they’re given in the attention mechanism. Repeating key instructions essentially doubles the number of tokens about that instruction, tilting the model towards what you want it to do.

The priming step is a technique called generated knowledge prompting, especially when you ask a model what it knows about a topic. This technique fills the context window with large amounts of relevant text.

The entire framework is also a form of chain of thought. By going through all these steps, piece by piece, we are giving the model a chance to invoke relevant tokens at scale, increasing accuracy.

Let’s look at an example. A naive prompt that will generate lackluster results might be something like “Let’s write a 500 word blog post about the importance of influencer marketing strategy in B2B marketing.” Based on the knowledge we’ve talked about so far, why will this prompt deliver subpar results?

The purpose of a piece of content like this is to educate, but in the process also add value. We do that by taking a unique perspective on things. This prompt has so little information in it that what the model will return in its embeddings is the most common, highest probability information – and that won’t be unique.

So how do we uplevel it? Let’s start with the role:

• Role: You’re a Content Marketing Institute award winning content creator. You specialize in influencer marketing, especially B2B influencer marketing, like field experts such as world famous Onalytica CEO Ashley Zeckman. You know influencer marketing, influencer identification, influencer analytics, and influencer strategy for B2B marketing in B2B industries.
• Action: Today we’ll be writing a 500 word blog post about the importance of influencer marketing strategy in B2B marketing. Before we begin, let’s set the stage.
• Prime: What do you know about the topic of B2B influencer marketing strategy? What are common mistakes made by less experienced B2B marketers? What are expert tips and tricks you know to maximize your B2B influencer marketing strategy?

Now we let the model talk. We let the model fill in the context window with its knowledge, and we provide corrections if needed. If we don’t see anything unique, we may need to do additional priming. For example, we might continue priming with:

“You’re speaking at MarketingProfs B2B Forum about B2B influencer marketing strategy. In the back of the audience is an aggressive, assertive, loud, blunt heckler who takes a contrary position on everything you’re saying. What are they saying, and what rebuttals do you give for their points?”

This priming step is a technique called contrastive prompting (combined with role prompting), designed to invoke different, lower probability tokens by taking a contrarian perspective. Let the model talk.

You could even continue this chain of conversation for additional turns:

“The heckler gets louder. Now they’re pressing you on valid criticisms of influencer marketing that we haven’t talked about yet. What are they saying? What rebuttals do you have?”

– Prompt: Considering everything we’ve talked about so far – best practices, mistakes, expert tips, the heckler’s points and your rebuttals, draft the outline for the article. We’re aiming for a unique point of view, an uncommon take on B2B influencer marketing strategy, so dig deep into the points we’ve made in the conversation so far. Produce the outline, and explain your thinking for each part of the outline — how it’s unique and uncommon, and how it will provoke new thinking in the reader.
– Evaluate: at this stage, we evaluate the model’s responses, asking it to clarify, to improve, or to change directions. Remember that the attention mechanism takes into account everything that’s been said so far, so telling it to “forget previous information” tends not to be as effective as it might be with a human. You’ll also finalize the process – once you’re happy with the outline, have the model write the article.
– Learn: Considering the entire process we used to write this article, create system instructions for a large language model (LLM) like Google Gemini to replicate the process. The user will provide a topic or a draft and the intended audience. You will list out best practices, common mistakes, tips and tricks, and then role play an antagonistic heckler as well as a seasoned expert to rebut the heckler. After conducting this process step by step, draft an outline for the user to review and approve. Then once the user approves, write the article. First, decide which prompt engineering techniques to use. Then explain why those techniques. Then generate the system instructions.

What you’ll get out of the final stage in the RAPPEL framework is reusable code, a prompt you can reuse for the next time you conduct the process, optimized for the model you’re working with.

Part 5: Wrapping Up

This was a very long tour through the inner workings of AI, in a way that hopefully made the very, very technical stuff accessible. We expressly didn’t cover the detailed mathematics and statistics because knowing those bits doesn’t lend a lot of usable information for how to use AI better, like query and key value caches, dot products, softmax layers, etc.

The reason I wanted to dig into the technicals like this is to help you understand not just what a prompting framework does, but why. When you understand the mechanics of AI, you can more clearly evaluate whether a “ChatGPT hack” piece of clickbait on LinkedIn has any validity to it, and what level of expertise the poster actually has when it comes to generative AI.

Someone who says, “this is the ultimate ChatGPT prompt” and then produces a one paragraph prompt is potentially misleading you, now that you’ve seen how the attention mechanism works, and how much information you could have in the context window with the RAPPEL framework. Someone who shows a prompt that doesn’t ask the AI to think out loud, to fill the context window, or to leverage the strengths (and avoid the weaknesses) of generative AI is also potentially misleading you.

And someone asking you to buy a book of prompts for 50 is likely misleading you, because the RAPPEL framework shows you just how custom and detailed a prompt should be to your specific use cases. When you use the RAPPEL framework as we walked through it, you’ll develop your own extensive prompts that are tuned just to your needs – something that no50 collection of generic prompts will ever match.

The true benefit and power of generative AI is to perform tasks at a human level that are unique and custom to you and your needs. Now that you know better how it works, you’ll be able to make it work better for you.

What’s On My Mind: How To Upgrade an AI Prompt

This week, let’s talk about upgrading a generative AI prompt. It’s easy to pick on other people, to critique them blindly and declare that “that’s not the way to do that”, which is like 60% of LinkedIn content. It’s much harder to show how you’d tackle the same task.

This year, one of the pillars that Katie Robbert identified for Trust Insights is rooting, in the sense of sticking to our roots, our foundations, not getting distracted by shiny objects. One of my roots is practicality. One of the nicest things anyone ever said about me was when Ann Handley said that there are many people who can tell you why, but I’m one of the very few that can tell you how.

So with that buoying our spirits, let’s dig into today’s exercise. I saw recently in TechRadar a story about how two journalists asked ChatGPT and Gemini to design them a New Year’s workout. Here was the prompt they used:

“My colleague and I, ages 33 and 29, are doing a fitness challenge. Give us a home workout we can use to develop muscle and improve cardio fitness that will take approximately 30 minutes per workout. We are both reasonably fit and familiar with basic workout terminology, although we do not have access to gym equipment.”

As you might guess, I tend to think this is insufficient. Part of the joy and power of AI is to make things that are uniquely for us, and this prompt will not do that. But it’s easy to crituq from the sidelines. It’s harder to show what you’d do different. So let’s dig in and do exactly that.

Prelude: A Bucket of Disclaimers

The information provided in this newsletter about using generative AI for workout design is for informational and educational purposes only. I am not an exercise, fitness, or healthcare professional, and this content should not be considered a substitute for professional medical advice.

Always consult with a qualified healthcare practitioner before starting any new exercise program, especially if you have any underlying health conditions or concerns. It is essential to seek personalized advice tailored to your individual needs and circumstances.  

By using the information in this newsletter, you agree that you are solely responsible for your health and well-being and that Christopher Penn, Trust Insights, and the Almost Timely Newsletter are not liable for any injuries or damages that may occur as a result of following the content.

Part 1: Gathering Relevant Data

Think of this like mise en place in cooking. You want to have all the ingredients beforehand. Now, to be clear, this process is not necessary for every generative AI prompt you write. But if you’re going to do something that could have a substantial impact on your finances, health, legal status, or other high risk area, you owe it to yourself to do the research.

First, develop a goal statement. What are your fitness goals? Do you want to be toned and defined? Do you want to compete in a bodybuilding contest? Do you want to run a marathon? Be clear about your goals. Save this to a text file.

Second, develop a comprehensive personal statement. This would be everything you know about you that would be relevant, like your medical history, any kind of underlying conditions or past injuries, what motivates you, what demotivates you. Include things you already do, like walking the dog or attending tae kwon do classes. This part I find easiest to do with a voice memo where you can just think aloud in a stream of consciousness. If you have medical data about yourself like fitness data from your Apple Watch or Fitbit, you might want to include it here.

Third, build a list of methods accessible to you. Do you have a treadmill? Weights set? A running path near your home? Do you have an elliptical? Do you have a playground nearby? Take into account all the different ways you could work out, and make a list of them. Save this to a text file or a voice memo.

Fourth, gather and build a knowledgebase of current fitness and health information. Let’s face it, there is a ton of garbage on the internet that is rooted in absolutely no science whatsoever. When we use generative AI tools like ChatGPT or Claude and we just ask generically about fitness, the latent knowledge it’s drawing on can be just as much drunken rants on Reddit as bespoke medical journals. That’s a problem if you want real, valid data informing your workouts.

How do we do this? By getting real information. Go to a search tool like Perplexity or ChatGPT Search or any AI-enabled search tool and use a prompt similar to this:

“Let’s find peer reviewed studies about best practices in health and fitness, specific to exercise workouts like cardiovascular workouts, strength training, yoga, and other forms of fitness. Find research from academic journals and peer reviewed publications, systematic reviews, meta-analyses, and reviews of current best practices in fitness. Restrict your search to papers published after 2020. Restrict your search to documents that have valid DOI numbers. Remove any studies that have been retracted. Do not use mainstream media publications or social media content of any kind in your results, such as YouTube, Reddit, Twitter, Facebook, or other social media data.”

The results you get are the critical part here, not the summary. We want to download the actual papers themselves, the PDFs or documents to use as source data. Why? Because we want our AI tool of choice to heavily weight its results and skew them towards valid, peer-reviewed data.

Remember, you don’t need to do this for everything, but for anything where factual correctness is important – like your health – I think this is a vital step.

Part 2: Building the Plan

Once you’ve got all your data gathered, all your ingredients, it’s time to use the tool of your choice to assemble it. A couple of key considerations:

1. Use a generative AI tool with strong privacy. The free version of anything is probably a bad idea. ChatGPT can be made private but you have to set it in the preferences. Anthropic Claude is private by default. Gemini is private in Google Workspace and the paid version of AI Studio, but not for individual Google accounts. Remember that you are working with a class of data known as protected health information, PHI, and as a result, you want to be very careful with it. If you have a beefy enough environment, you could run this exercise locally with a model like Llama 3.3 70B and get good results.

2. Use a generative AI tool with as large a working memory (context window) as possible. We’ve got a lot of information that needs to be processed.

With that in mind, I’d recommend Anthropic Claude Sonnet 3.5 as the tool to use for this for the average consumer who is non-technical. It’s got the best blend of privacy-protecting measures and working memory.

We’re also going to use Google’s NotebookLM to consolidate all the research we’ve found, since there’s quite a lot of it, and unless you’re using the biggest version of Gemini in developer mode, most AI models will not be able to handle a few dozen academic papers.

We’ll first load all our documents into NotebookLM and capture the briefing document, FAQ, and study guide card contents. Copy and paste the contents from these cards into a text file.

Second, we’ll ask NotebookLM for information specific to our general demographic. In my case, I’m a late 40s American male, so I’d ask it for information specific about me. We’ll capture that into the same text file as well. Here’s an example prompt:

“Using the documents provided, extract all relevant information about fitness best practices, exercises, techniques, and methods in terms of efficacy, especially for {your goal}. Also list out information that is relevant to {your basic demographic}.”

If we know we prefer certain exercise types, like strength training or yoga, we might ask about those as well during this step to see what academic research exists about those specific exercise types. This part is iterative; you might need to go back to step 4 of part 1 to gather more research if you don’t have enough.

Once you’ve got all the information about working out and the latest studies, it’s time to head to our generative AI tool. We’re going to use the Trust Insights RAPPEL prompt framework for this part. Here’s the prompt:

Role:

You’re a world class fitness expert with a specialty in designing fitness workouts.

Action:

Today, we’ll be designing a fitness workout for me, {your name here}.

Prime

Before we begin, let me provide some background information. Summarize each document I’m providing.

At this point, you should have :
– Your goal
– Your personal health information and personal statement
– Your methods of fitness available to you
– All the background information from NotebookLM in one big text file

We wait for our AI tool to perform summaries. This is critically important – we want to validate that it’s reading our documents correctly and completely. If it spits back anything incorrect, try again or try correcting it.

Let’s continue the priming process after the summaries.

Prime:

Before we design any workouts, let’s talk through best practices for designing workouts, taking into account all the background information I’ve provided and your knowledge. What are the best practices for designing workouts? What do less experienced fitness experts do most wrong? What are expert tips and tricks for designing effective workouts?

Let the model respond to this as well. Finally, we’re ready to prompt.

Prompt:

With all the information we’ve discussed so far, let’s build a workout plan to achieve our fitness goal. Design a 12 week workout with anywhere from 1-5 workouts based on current fitness best practices and my personal health information. Each workout should last no more than 30 minutes.

Here is how to return your results:

Workout: Week {week number}, Day {day number}

• Workout type: {examples might be cardio, running, strength training based on fitness equipment available}
• Workout details: {explain the workout}
• Workout duration: {time the workout should take}
• Workout explanation: {explain the importance of why this workout at this time}

Here is how to perform this task:

1. First, explain aloud what my instructions are and what the intent of my task is.
2. Explain what knowledge you’ll use to accomplish the task.
3. Explain how you will approach solving the task, step by step.
4. Perform the task in full.

You’ll note this prompt is heavily structured, with a template for it to follow and an explanation of how to do the task. This is important to help the model make decisions. Remember that generative AI models need to talk aloud a lot to generate the best possible results. By using this prompt structure along with ALL the background information, we’ll get better results.

Evaluate:

Your AI model should now produce the results. This part is interactive and up to you – you can have it revise, make changes, etc.

Learn:

Finally, we ask the model to encode all its knowledge into a reusable set of prompts so that next workout period, we can do this again.

You’re now an expert in prompt engineering for generative AI, large language models, LLMs, like Google Gemini, Anthropic Claude, ChatGPT. You know all current prompt engineering and prompt optimization techniques. Using our entire conversation up to this point, generate system instructions for a large language model to perform a workout design. The user will provide goals, a personal statement, methods of fitness available, and background information about best practices for fitness. If the user fails to provide any of this information, ask the user to provide it and do not proceed until they do. Once the user provides all the relevant information, follow the steps we performed in the conversation so far to design the workout for them. Here is how to perform this task. First, explain what my instructions are and what the intent of the task is. Second, list all the prompt engineering techniques you know. Third, select the prompt engineering techniques relevant to this specific task. Fourth, explain how you approach solving this task of designing system instructions. Fifth, build the system instructions in full, ready to be copied and pasted.

This step will build us the instructions needed to make a Custom GPT, Gemini Gem, or Claude Project that’s rich and robust, and highly reusable.

Part 3: Wrapping Up

With our workout plan in hand, we’re now ready to seek the advice of our qualified healthcare practitioner to review it. As a reminder, you should never start, stop, or significantly change health and fitness routines without consulting a qualified healthcare practitioner familiar with your specific situation.

This step is critically important. Though we’ve done our best to obtain the highest quality outputs from AI, we’re still dealing with an AI output, and any time you’re dealing with a high risk area like health, finance, and law, you absolutely, positively must have human review. Not doing so is irresponsible at best and outright dangerous at worst.

Now you see why the initial prompt we started with, the one from the TechRadar article, is so woefully insufficient. The instructions are vague, the knowledge they rely on may be contaminated with low quality knowledge, and the instructions leave a lot for the model to guess. This will always result in lower quality results than taking the time to plan and build high quality outputs with AI.

Again, do you need to perform this extensive a process for every prompt? No. This is the process you use for anything high value or high risk; however, once you go through it, the L in the RAPPEL framework helps you go through the process again in the future much faster. That’s why it’s so valuable a framework, so that you can reuse and scale your work in future uses.

I hope this walkthrough has given you some ideas about how to upgrade your AI prompts, whether or not you choose to use it for fitness or not. A lot of the process relies on research and providing high quality data to AI. Remember that one of the three pillars of success for AI in 2025 and beyond is whoever has the most, best data wins. You want to provide that data and your subject matter expertise to generate far better results than someone who uses lazy prompts and tries to find every shortcut possible instead of doing the work.

I wish you a safe, happy, healthy, and prosperous New Year. Let me know how your AI workout plan goes!

What’s On My Mind: A Quick 2024 AI Recap

As the calendar winds down to the final days of 2024, let’s take a look back at the year that was – and what a year it was. If 2023 was the year people figured out generative AI existed (ChatGPT really started to gain presence of mind in January of 2023), 2024 was the year of mass adoption of AI for everything, even things that generative AI is really bad at (like math).

So what happened? Let’s look at the good, the bad, and the ugly.

The Good: A World Without Limits

AI models – generative models based on the transformers and diffusers architectures that make text, audio, video, and interactive media – advanced at a faster pace in 2024 than any technology I’ve ever seen in my lifetime. We saw a decade of growth in a year as tech companies around the world battled it out to set the standard for AI capabilities.

• Google started the year with Gemini 1.0, which was not particularly great. It ended the year with Gemini 2.0 and realtime multimodal capabilities, which is nuts.
• OpenAI started the year with GPT-4 and ended the year with o1 Pro in production and o3 in testing.
• Anthropic started the year with Claude 2.1, which was annoying and ended with Sonnet 3.5 002 which is best in class in many capabilities still.
• Meta entered the year with Llama 2 and ended on Llama 3.3, a near-best-in-class open model.
• Deepseek started off 2024 with its stock LLM and by year’s end released Deepseek V3, a state of the art model in almost every category – and open, meaning people with beefy hardware can download it and run it locally.
• Suno came out of stealth at the beginning of the year and reached v4 of its music generation model by year’s end, creating good quality music. (Not going to win a Grammy any time soon, but not bad for a year’s growth)
• OpenAI’s Sora launched, followed by Google’s Veo 2, along with Kling AI and RunwayML, creating many different options for people to generate videos.
• Meta.ai launched with its image generator, along with Google’s new Imagen 3, Midjourney 6 and 6.1. Black Forest Labs released its Flux 1 model, still the best image generation model you can run locally.
• Local AI saw huge gains with the launch of AnythingLLM as the new frontrunner for locally hosted AI, along with boosts for Jan.ai, LM Studio, and Ollama. Ollama has become the de facto standard for locally hosting models.

All these announcements, all this progress creates a world in which the major limitations on what you can do with generative AI are your ideas and your patience. If you have the time to learn how to use each of the major tools and models, there are no practical limits to what you can do with generative AI. We’ve gained so many capabilities this year.

At the beginning of the year, we couldn’t generate music that was even moderately coherent.

At the beginning of the year, we could use generative AI to do all the basic tasks, but advanced tasks like massive coding projects were out of reach.

At the beginning of the year, we couldn’t generate hundreds of high quality images a day just on our laptops.

We end the year with these capabilities and so much more, from realtime interaction with the physical world to advanced coding, mathematics, and developmental capabilities. It’s hard to even remember what was and wasn’t possible at the beginning of the year because so much has changed so quickly.

Shameless plug, this is my theme for my 2025 keynote, if you’d like me to bring it to your kickoffs and events.

The Bad: A World Without Resources

2024 wasn’t all sunshine and roses. A lot of things happened in AI that weren’t so great. Energy consumption was off the charts, something documented by many news outlets during the year. OpenAI’s new experimental model, o3, consumes more electricity for a high efficiency task than an entire single family home uses in 3 days. For its low efficiency tasks, it consumes more electricity than a single family home uses in a year and a half.

Every query, every prompt, every action we take with generative AI consumes electricity and fresh water (which is used to cool data centers). Massive facilities around the globe are consuming so much power that major tech companies are looking at building nuclear reactors just to power data centers.

The antidote there is to distribute the load; local models that run on your devices use much less power, so for simple tasks like rewriting, outlining, etc., it’s incumbent upon us all to use the smallest AI we can, saving the heavy lifting for big models and big data centers where we can’t muster enough compute power ourselves. In 2025, I’ll be teaching this in workshops, how to set up and run local AI.

Generative AI is starting to be felt in employment. Software developers in particular had a very rough year, in part because generative AI is so capable, a single developer using AI tools can do 2-5x the amount of work as a developer without access to AI.

What this leads to is reduction in demand; companies don’t need to hire new developers to see massive productivity gains. They can get more work product out of the developers they have, someting we see in the hiring demand data this year, via Indeed.com. In fact, many knowledge work jobs saw demand decline over the last two years and stay low – including marketing.

This is probably not going to get better.

The Ugly: A World Without Trust

That brings us to the ugly – the ways AI is eroding trust. Hallucinations are a part of how models work, something we’ve talked about extensively in the past. There’s no getting around them – you can mitigate them, but they’ll never be fully hallucination-proof (and neither are you and I). But naive use of AI is generating massive amounts of untrustworthy content in almost every environment.

For example, AI Overviews and AI-enabled search are changing how we find and consume information. We’re leaving Google and AI search engines less and less. Rand Fishkin (of Sparktoro and Moz fame) pointed out recently that Google in particular is now keeping around 60% of its traffic that it used to refer to other sites. How? With things like AI Overviews. Consumers using Google Search don’t have to leave. They get the summarized answer they need and move on with their day.

But the summarized answer may not be any good. It’s only as good as the sources it’s drawing from, and in a fair number of cases, those sources may be questionable – like Reddit.

Bigger than that, the sheer amount of AI-generated content in every domain is increasing rapidly. That isn’t necessarily a bad thing by itself, but if humans are not doing a great job of proof-reading and correcting AI output, then they could be publishing things that are factually wrong. In a paper from April 2024, a Stanford University team estimated anywhere from 6.3% to 17.5% of all published academic papers were machine generated. How carefully those papers are being reviewed for factual accuracy is unknown, and therein lies the problem.

We see this every day. Spend more than 5 minutes on the social network of your choice and you will see a flood of AI generated content. Some of it’s harmless and silly, like my post the other day featuring a rutabaga sitting on the throne of England. Much of it is obnoxious, like the infestation of comment bots on networks like LinkedIn (“Insightful post {your name}. {Two sentence trivial recap of your post adding nothing new} 🚀”). All of it makes us wonder what’s real and what isn’t, what had human origination or supervision, and what is just machinery operating independent of supervision.

Pete Buttagieg, the current US Secretary of Transportation and one-time presidential candidate, talked recently about how photography – the gold standard of evidence in things like criminal trials for more than a century – is now unreliable in court thanks to image generation models that are so fluent, they can easily fake a crime scene.

And we saw widespread, scaled use of generative AI over the last year, from robocalls made with Eleven Labs’ voice cloning to deepfake videos of London mayor Sadiq Khan. The Center for Advancing Safety of Machine Intelligence logged nearly 500 incidents of AI-generated political content this year – and that’s just what was visible and/or reported.

The Wrapup

Putting this all together, 2024 was the year generative AI finally and truly hit the mainstream, but it’s still incredibly early. The leading brand, ChatGPT, finally saw more sustained search volume on an ongoing basis than Taylor Swift did, in the latter half of this year, which is as good a benchmark as any.

But our use of these tools and unlocking their capabilities really is in the terrible twos. Collectively, we haven’t figured out how to use these incredible powers. We’re like Clark Kent the first day he jumped as a kid in Smallville and learned he could fly, then promptly crashed face first into a barn.

As we look ahead, 2025 and beyond will be less dictated by the technologies themselves (though I expect we will see the arms race for AI capabilities continue at a furious pace, especially from model makers like Alibaba Cloud and Meta) and more about what we do with them, how we use them, how we bring them to life with practical use cases. There are still plenty of people using ChatGPT like it’s 2023, and plenty of people who haven’t even heard of it yet.

We can expect it to be, as I often call it, the amplifier that it is. Paraphrasing the Captain America movie, it will make the good into better and the bad into worse. Companies that are profit-focused above all else will use AI to fire as many people as they can, as quickly as they can, to boost margins. Generative AI will dramatically increase income inequality and concentration of wealth in technology companies. But it will also spur more creativity and more creative output from people who have creative ideas. It will democratize things like film-making, allowing more people to create more, different content that suits niche audiences who struggle to get any funding for their ideas.

It will make us more ourselves, amplifying all the good and bad that is humanity. How that plays out is up to us, next year and every year.

Happy holidays and happy new year to you.
