In today’s episode, are you relying too heavily on no-code solutions or expecting AI to solve every problem? You might be surprised to learn that sometimes the most efficient and powerful answer is writing code. You’ll discover why coding remains essential for deterministic tasks and how even non-coders can leverage AI to generate code for them. Tune in to understand when coding is the superior choice and how it can dramatically increase your problem-solving capabilities.
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
In today’s episode, sometimes you just have to code.
One of the questions that comes up more often, I would say, than almost any other question when we’re talking about generative AI is, what is the low code or no code way to do any given task?
Of course, there are no shortage of vendors that would say, “Our no code platform does this,” and only for an egregiously large amount of money per month. You know, you can do anything with our platform without having to code, which I understand. I understand that not everyone has an aptitude for coding. Not everyone has the knowledge of how to code. Not everyone even has the capability to run code on their computers. If you work at a large enterprise, your computer may be locked down from being able to execute code because code is very powerful. And if you get the wrong code, you can execute it, and it can do bad things.
But sometimes you just have to code. Sometimes there isn’t a good substitute for coding because, in the same way that writing is thinking, coding is thinking, too. Coding is a form of writing. It’s a form of writing where you’re writing to a machine instead of a human. And in the same way that good writing elicits things like responses and emotions and visualizations, code does exactly the same thing. It’s just that it’s not a human reading the writing; it is a machine. When you write Python code or R or PHP or Ruby or any of the dozens of coding languages that exist, you are writing to a machine.
The difference is when you or I, as humans, get an ambiguous, kind of confusing letter or email or a direct message from another human, we can generally parse out maybe what was going on. When we write code to a machine that doesn’t follow its conventions, its syntax, the machine’s like, “Nope, not going to run it. Can’t do anything with it. Sorry.” And yet, there are many problems that are better off solved with code than without.
In particular, any time that you need a deterministic outcome, here’s what I mean. Language models, like the ones of Power Chat GPT, are probabilistic. They will never—they’re never guaranteed to generate the same result twice. You’ve experienced that. And you give it a prompt, and it answers it thematically similar each time, but each response is different because it’s invoking different probabilities and different ways of answering the same question that are all similar but not identical.
When you run code, you open up a Python script and run that code, you are doing something that is deterministic, which means that there is a right and wrong answer. The right answer is that the code runs. The wrong answer is that the code does not run. It gives you errors, it just does nothing, and so on and so forth.
The other day in our Analytics for Market, a Slack group, a colleague said, “Hey, I’ve got this Word document filled with JSON, JSON markup. How do I process this? How do, you know, does anyone have a tool to do this?” The process for doing that—there are a gazillion and a half different JSON to plain text converters, or you could write the necessary code, or you can have generative AI write the code for you and to say, “I want you to make a piece of code that converts JSON to plain text.”
But this person’s like, “I don’t code. I can’t code. Um, I don’t know how to run code.” And so they used Google Gemini to try and do it for them, and they got a—they said they got a good enough result, but the task that they were giving, that they were presenting, was a deterministic task to change from one format to another. There’s a right and a wrong answer, not a probabilistic task. AI was the wrong tool for the job there. When you’re doing math, AI is almost certainly always the wrong answer because, again, probabilistic tools do not know how to count. Chat GPT can’t fundamentally strip away all the extras and all the fanciness. It can’t count. It’s guessing the answer to equations, things based on previous examples that it’s seen. That’s not how mathematics works. Mathematics is a computational language. It’s a symbolic language, and so code is would be the way to solve that. You’re not going to do it with AI.
So the point of this is to say sometimes you just have to code. Yes, you can use a vendor to do to offer low code and no code options, and you will pay handsomely for that privilege, or you can take a step outside your comfort zone and say, “How do I run this code? How do I get set up to even run Python on my computer?” Because once you take that step, it opens up a whole universe of things that you can do. Maybe there’s a report you run at the end of the month, and you spend hours and hours in Excel cleaning it up every month, and it’s the same every month, and you’re like, oh, there’s got to be a way to do this.
There is. You describe exactly what you’re doing. Maybe you take a screencast of what you’re doing. You go to a tool like Chat GPT or Gemini and upload the video, and you say, “How do I do this with Python code?” And if you’re set up to do that, and you can run it locally on your machine, then suddenly you go from hours and hours to maybe minutes, maybe even less than minutes, to do the exact same task using code that you didn’t have to write yourself because a machine wrote it for you. But it solves that problem. It makes that problem much less of a problem.
One of the things that we do at Trust Insights all the time is write code—write code to solve where we know we’re going to see this problem again. Every time someone says, “Hey, can you just run a report on this?” I know our clients—I love our clients—our clients are wonderful people. When I get a request to report, almost always I’m going to see that request again. I just know it. Even if they say it’s ad hoc, it’s never ad hoc because a week later, a month later, a year later, someone will come back to say, “Oh, yeah, that report, can I—can I get another version of that? Can’t get an updated version of that?” And approaching it with the mindset of code means turn the report, the code on, run the report again, client is happy, I’m happy, and I didn’t have to reinvent the wheel again.
Sometimes you just have to code, and if you can become comfortable with that, if you can become skilled at that, there’s a whole universe of solutions to problems that you didn’t even know you could solve, but your value as an employee or as a contractor or as an entrepreneur is dramatically higher.

In today’s episode, are you still thinking of generative AI as just a smart intern? You’ll discover that new reasoning AI models are more like having a brand new manager on your team, capable but needing the right direction. You’ll learn how to shift your approach to delegation and prompting to get the best results from these powerful tools. Tune in to understand how to effectively manage these AI “managers” for maximum impact.
Mind Readings: Treat Reasoning AI Models Like New Managers
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
In today’s episode, welcome to the new manager.
Now, I have said in the past in my keynotes that regular generative AI language models, like the ones at PowerClaude or Chat GPT or Gemini, are like the world’s smartest, most forgetful interns, right? They’re the intern that’s got 255 PhDs. They have a PhD in everything, but it’s day 1 for them. And they’re like, where’s the restroom? Where’s the coffee machine? I don’t know my way around. They’re so capable, but you have to delegate to them like it’s day 1 on the job in perpetuity.
They have no memory. They are what’s called stateless. All AI models are stateless, right? They can’t remember everything. Every time you start a new chat, it’s like the intern’s first day again, which admittedly is a little bit frustrating, but that’s the nature of the technology. Language models today are stateless and have no memory.
Now, there are some technologies that allow them to remember, but they’re not open to the public and they’re not something that you would ever want open to the public because of the risk of the model just being corrupted. Microsoft found this out the hard way when they released Tay, their Twitter chatbot that could learn from people’s responses to it. Yeah, you can—if you don’t remember what happened, you know exactly what happened. It was turned into a racist porn bot in about 24 hours. Thanks, Internet. That’s why, among other things, today’s generative AI tools do not do that.
Now, there’s a whole new crop of models called reasoning models, like OpenAI’s 01 or O3 or Deep Seeks R1 or Gemini 2 Flash Thinking. And these reasoning models are not interns anymore, but they’re like a brand new manager, a junior manager, equally brilliant, equally forgetful, can’t remember anything still, but it needs less handholding. You don’t need to tell a reasoning model to think step by step or to take a step back or to make a checklist or any of the general process-oriented prompts that we use with regular models. They do that automatically. And in fact, both Open AI and Deep Seeks expressly tell you not to use things like that in their prompts because you may give conflicting instructions that degrade the model’s performance because it’s got its own built in. It’s called chain of thought, and specifying chain of thought can—it’s basically confusing.
But you absolutely must do, which we encapsulate in the Trust Insights Prism framework, which you can get at trustinsights.ai/prism, is basic good management. It’s basic delegation, right? You tell the model what the problem is. You give the model a ton of relevant information. Here’s all the information you need to solve this problem in the same way that you give a brand new junior manager the necessary background information. And you give it success measures. How does the model know what success looks like?
You would do the exact same thing for any brand new junior manager, freshly promoted, freshly hired, right? They have the skills from—they remember from being an individual contributor, and they understand the basics of thinking through a process, but they still don’t know what the problem is or what you want them to solve.
In the same way that we treat regular models like interns and we delegate to them like interns, we need to treat reasoning models like fresh managers, brand new, the most junior manager on your team. Tell them why they’re doing something. Tell them what they should to be solving for, let them figure out how to do it, but be very clear, this is what success looks like. If you do that, you will be very, very successful with reasoning models and how they work.

In today’s episode, are you feeling stuck in your routine, wondering if there’s a better way to do things? You’re not alone! Generative AI has a vast knowledge base and can offer insights you might be missing. Tune in to discover how simply asking AI “what would you improve?” about your work can unlock faster, more efficient methods and save you countless headaches.
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
In today’s episode, let’s talk about what you would improve.
What would you improve? No matter what you’re doing, there’s probably other ways to do it. Some of those ways might even be better, but you don’t know them. You can’t see them. You’re locked into the way you’ve always done it because that’s what you know, and that’s okay. That’s human. That’s the way you and I are. I’m 100% that way.
AI is not. Generative AI models have seen most ways to do most things, and their knowledge in aggregate is greater than any human could ever hope to know — even for a tiny sliver of a specialization. So, whatever you’re doing, whatever your current standard operating procedure is, chances are there’s a better way to do it, and all you have to do is ask.
I was editing some video the other day in Adobe Premiere, which is a very, very powerful tool. I don’t know Premiere all that well. It’s not something that I have spent a lot of time with. As a result, I do things kind of inefficiently in Premiere. So, what do you do?
Well, what I did was I went into Google’s Gemini real-time, and I said, am I doing this right? The other day, I was looking at some Python code that we used to generate the Trust Insights newsletter. I was looking at thinking the HTML and CSS it generates is good, but it feels like we’re missing something. It could be better.
So, I asked generative AI, here’s my code and what would you improve? And it’s like, wow, dude, you’re not using media queries at all. Media queries are essential for adapting layouts and styles based on screen size. Without it, your email’s going to look like crap on mobile screens.
Like, well, clearly I’m not a designer. So, I asked it to tell me what the better way is. And it said, by the way, your string replacement and your reg-based HTML, brittle and error-prone — not good. Use beautiful soup to modify the HTML instead. It will be the single most robust improvement you can make to the code itself. And then I said, okay, cool, make the changes, and it did. It did a great job.
The lesson here is to ask the tools that we use to watch us do our work, to say, what would you improve? How could we do this better? And it will do a great job. They will do a phenomenal job with that.
If you find any task to be time-consuming, turn on an AI tool that can watch your screen and tell you, here’s some ways you could do this better. You will save so much time. You will save so many headaches, and you will find ways of doing things that you didn’t think about before because that’s the way these models work. They have a much bigger, wide perspective than you and I do.

In today’s episode, you might be hearing that AI is the answer to everything, but is it really? You’ll be surprised to learn that sometimes the latest AI tech is just a fancy way to do things we’ve already solved efficiently. We’ll dive into an example that highlights when AI is overkill and when good old-fashioned tools are still the best choice. You’ll gain a fresh perspective on when to embrace AI and when to stick with what works.
Mind Readings: Sometimes Generative AI Is Not The Answer
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
In today’s episode, oh, you don’t need AI for that.
Liza Adams shared something with me earlier, a demo (not hers) of an AI agent that someone had built that was using the browser-use/computer-use capabilities where AI takes control of your computer to crawl a website and do SEO analysis right in the browser.
The demo was saying, “Oh, check out this awesome agentic AI that is capable of optimizing your website in real-time.”
I took one look at this thing. They just reinvented Semrush and H-Refs and Maws and all of the other SEO tools that have existed for decades now in the least efficient, most computationally expensive, most error-prone, most resource-intensive way possible. This is really, really stupid. Whoever made it (and I’m not naming names because I don’t actually remember the name—I remember the name of the tool, but I’m not going to give it any daylight) is almost certainly one of the AI agent hype bros who clearly has an agentic framework or something to sell, but it’s completely utterly unnecessary. SEO and page optimization, even with generative AI, was solved a while ago, right? Page optimization, in general, was solved, I don’t know, 10 years ago, and using things like a Chrome web driver or a selenium in headless mode or any of the things to look at a page and understand how to optimize the content. Yeah, that’s been done. It’s been done and it’s proven. There are really great tools that do that now. This approach, using an AI agent/computer use, isn’t better in any way. It’s slower. It is more error-prone. It is more expensive. It was built clearly with the intent to show off AI agents, and it was also built by someone who doesn’t know a thing about SEO, pretty clearly. Otherwise, if you did, you would know that you don’t have to do most of the tasks that the agent was trying to do on page. You can do all that just with the HTML because you don’t need to see the interface to do SEO.
You need to see the code because that’s what Google sees. That’s what Bing sees. That’s what every search engine sees. They look at the code, and they don’t even look at the full code. They look at a slimmed down, trimmed version of the code. So, clearly, this was built by someone who knows agentic AI to some degree but has no subject matter expertise in the problem they’re trying to solve, and this reflects poorly on generative AI, on the AI community, and agentic frameworks because it comes across as really desperate and showing solutions in search of problems, right? It’s a hammer in search of a nail when the technology itself—there’s a legitimate use case for using that kind of agentic approach.
If you wanted to use a vision model, like Quinn, Quen’s VLM, that agentic framework would actually be really useful for UI testing to render the page fully as a person would see it and then run some usability tests that way. That would actually be really helpful. That’s not what this person built.
It would be even more helpful if you were to have a vision language model or any kind of language model doing computer use, you know, imitate someone with some kind of impairment or disability to test: Is your site actually compliant with, say, the Accessibility Canada Act or the EU’s Accessibility Act or the Americans with Disability Act? You know, pick a legislation of choice. There’s a lot of ways that that technology would actually be useful. This isn’t it. This is someone building an AI solution that nobody asked for, that does everything worse than the current market solutions.
Here’s the reality: Not every problem needs AI.
I say this as someone who is in love with the technology and has been for 12 years now. I started work with classical AI, what we call machine learning. I love this stuff. I do. Not every problem needs AI. Not every problem is suited for AI, like predictive analytics, for example. Most AI solutions, most modern, high-powered deep learning solutions, offer little to no improvement over classical statistical methods. That’s just a fact, right? Tools like seasonal arima still are within 1–2 percentage points of the most expensive, elaborate deep learning methods. And definitely not every problem needs agentic AI, which is incredibly resource intensive.
A lot of people make a good point that a single prompt to a tool like chat GPT costs like the equivalent of like an hour of electricity from a standard household and a bottle of water in terms of how much resources it uses. If you know anything about agentic AI, you know that everything that it’s doing is sending queries back and forth to some kind of language model, and if you’re not using a model locally on your computer, it’s going to a big data center. Now you’re sending dozens, if not hundreds of queries in a few minutes, and, you know, the electricity meter is spinning like this because you’re using so many resources to do something that you don’t even need AI for. This problem was a solved problem.
What I would love for people in the AI space to be doing is to say, what are the unsolved problems? One of the problems that AI could be used for that we can’t solve with today’s technology—that’s where we’re going to find value. That’s where we’re going to add value. This is something that my business partner and CEO, Katie Robbert, talks about all the time. When you lead with the technology, very often you end up with a hammer in search of nail-shaped problems. Finding none, you just start hitting things with the hammer and hope somebody finds it useful rather than annoying or injurious.
Start with your purpose. Start with the problem. Start with the outcome that you’re after. Start with the problems you can’t solve any other way, and think through what’s the best way to solve it, not the best way to use AI. AI is a set of tools and nothing more. It is not a magic wand. It is not an Oracle. It is not some wish-fulfilling jewel. It’s a prediction engine, and not every problem can be solved with it.
So that would be my caution today. Beware of the hype bros and the tech bros who are saying, “AI for everything.” It’s like seeing blenders for everything. Now, if I’m making steak, I don’t want to have a blender anywhere near my steak, no matter how good the blender is.

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.
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.

In this episode, a quick and dirty prompting hack: What, if anything, did I miss?
One of the superpowers of generative AI language models is that they’ve pretty much seen it all in one form or another. As we often like to say, history may not repeat, but it sure does rhyme, which means that AI models are spectacularly good at identifying your blind spots, my blind spots.
When we’re analyzing the latest news, like I did recently, I have no idea what the scope or scale of a big USA federal department like OPM and GSA is. I don’t even know what these organizations do. AI does. It’s read the information, and it can provide summaries very quickly and reasonably accurately.
Maybe you’re doing a competitive analysis of your sector, your products or services, your competitors. If there’s a dark horse in the race that’s within AI’s model or knowledge or grounded in search, you might not know who that dark horse is. AI does.
Maybe you’re doing a SWOT or Porter’s Five Forces or any of the things you learn in business school, and you’ve forgotten how to do it. AI knows, or AI remembers, and you could have it help you with that process.
Maybe you’re doing a content gap analysis, and you think you’ve done content on your focus topic to death. Like, “Oh, if I have to do one more SEO article about how SEO works,” you think to yourself, “There’s nothing new to cover.” There is. You might not know it. You might not see it because you’re so in the weeds in your own content. AI does. It can say, “Here’s all your content. Where are my blind spots? What haven’t I talked about yet that my customer would care about?”
Maybe you’re looking at your marketing plan for this quarter, doing scenario planning, and you have no idea what the second or third order effects of a big governmental change could be. Have things like tariffs happened before in history? Yes, plenty of times, by the way. What happened to the economy then? Do you know? You may not. Maybe you’re not a student of history. AI sure does. And yeah, we’re not going to touch that, but ask AI.
AI models are imperfect oracles to be sure. They are probabilistic, not deterministic, which means that everything they do is guessing. Sometimes they guess well, and if they’re prompted poorly, they guess poorly. But as models improve and as training datasets get larger and cleaner, their accuracy is improving to the point where they’re useful for these kinds of exercises, seeing what we can—to finding our blind spots because we’re so close to our stuff.
If we can give it our stuff and say, “Why are we missing something? What have we forgotten?” At the end of your prompts, anytime you’re doing any kind of analysis, ask this simple question: “What, if anything, did I miss?” You will be surprised at the answer a good amount of the time—potentially a little embarrassed, like, “Oh, I can’t believe I forgot that.” But you’ll be surprised at just how useful AI is for that.

In today’s episode, are you lost in the sea of 1.39 million AI models? You’ll gain clarity as Christopher Penn reveals his expert recommendations for the best AI models across platforms like Claude, OpenAI, and Gemini. You’ll learn which models excel in different areas, from general use to complex reasoning. Watch now to simplify your AI choices and make the right decision for your needs.
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
— START OF EDITED TRANSCRIPT —
In today’s episode, the big question everyone has: which model should I use? What AI should I use?
There are 1.39 million different AI models you could use, and that’s not an exaggeration. It’s the actual number from the Hugging Face repository. If you go to huggingface.com, you can see the number of models. At the time of recording, it is 1.39 million, soon to be 1.4 million.
Even in your favorite consumer interfaces, like Chat GPT or Gemini, or Claude, there are now half a dozen different choices. And as many people have pointed out, they’re not particularly well named. The choices are not intuitive. Like, should I use GPT4o or 01 or O3 Mini or O3 Mini High? You look at it and go, “But what’s the difference?” It is not clear. Clearly, marketers have not been naming these things.
So let’s simplify these things as best as we can. But before we begin, disclosure: no one, unfortunately, has paid me anything for these recommendations, so they are untainted by commercialism. If you’d like to pay me for recommendations, please reply in the comments.
First, if you had to pick just one AI tool for the non-technical user, like if my dad said, “Hey, which AI should I use?” my answer today remains Anthropic’s Claude Sonnet 3.5, the current version of Claude. It is the best all-around model. And while it lacks some of the really fancy features that you see in OpenAI stuff—things a lot of people don’t need—a lot of people are still prompting like it’s 2023. Claude is incredibly accurate, following instructions, it generates great code, it generates great diagrams, it’s super smart, and your data is always private. Use the paid version, $20 a month. That would be my recommendation.
Now, if you are in the OpenAI/Chat GPT ecosystem, there are two primary models that you should care about. The first is GPT-4o. This is their best multimodal general purpose model. It will do most of what you want. It can generate images from prompts and stuff like that. It’s a reasonably smart model. It’s a decent writer. It does have a lot of Chat GPT-isms, so you have to be very specific and thorough in your prompting.
For reasoning, use 01. This is their best reasoning model. It’s great for thinking things through, like judging the unintended consequences of a piece of legislation or similar exercise where you need a lot of thinking things out loud.
In general, for OpenAI’s ecosystem, for the average non-technical user, any model that ends in the word “Mini,” like O3 Mini or O1 May, is not worth your time. They’re not particularly good, and the new O3 model—the current ones that are available as of the time of this recording, the O3 Minis—they’re dumb compared to 01. Use 01.
If you are in the Google Gemini ecosystem, there are two primary models you should care about. 2.0 Pro: this is their best all-around model. Despite its labeling in the interface, it’s very smart, very thorough, good general purpose model. 2.0 Flash Thinking: this is Google’s best reasoning model. Again, for complex questions where you have a lot of background information and it’s a thing you really want to think things through, it’s very good.
They do have another model called Flash—regular Flash—and nothing to do with the TV show, sadly. I feel like that’s a missed opportunity. Flash isn’t as fast and nice; it’s not as smart as Pro.
If you are self-hosting models and you have big hardware—we’re talking tens of thousands of dollars in hardware—there are two primary models. DeepSeek V3: this is their best open model on the market. And remember that we’re talking not their website, we’re talking something you download and run on your hardware. And then DeepSeek R1 is the best reasoning model on the market, hands down. As with V3, this is one that you download and run, or you run through a service provider that’s in your country. It is not—do not use the ones that are hosted by DeepSeek itself.
Now, people ask, “What do I use in my day-to-day go-to?” Because I’m a more technical user who uses models to code, and I need a lot of working memory for these models. I use Google’s Gemini 2.0 Flash Thinking the most, followed by Google Gemini 2.0 Pro. Google’s models are fantastic for my specific use cases, which are not the average use cases for most marketers.
So that’s my suggestions for what AI you should use. Use the ones I’ve mentioned for now, and again, that list is going to be subject to change, just be aware of that.

In today’s episode, are you concerned about the hidden energy costs of AI? You’ll be surprised to learn just how much power generative AI consumes, potentially rivaling a significant portion of US household energy use. You’ll gain critical insights into the massive energy footprint of AI and why efficiency is the key to its sustainable future. Tune in now to understand the challenges and the innovative solutions being developed for greener AI.
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
— START OF EDITED TRANSCRIPT —
In this episode, Jason asked a very interesting question: How much energy does generative AI consume?
We don’t know. We don’t know the exact answer because there are a lot of things that go into it, but we can at least get a ballpark, kind of general idea. Nvidia, the company, owns 98% of the GPU market, the graphics processing units. These are the high density hardware that big companies in their data centers need to run and provide AI services.
Your average GPU costs between 30,000 and50,000 for this massive unit. And Nvidia is the king of the hill on this. There are other companies like Apple, but almost every data center is Nvidia.
So if you go by the public estimates of how many GPUs Nvidia has sold per year for the last three years from their earnings calls, it goes like this. Remember, these are data center GPUs, not gaming cards, because Nvidia does make video game cards, but we’re not talking about that. We’re talking industrial stuff sold to big data centers.
In 2021, they sold 1.58 million of these things. In 2022, 2.64 million. In 2023, 3.76 million. And last year, estimated 4.8 million. Now, all of these—the 2021s are going to be Nvidia A100 cards, big monstrous cards. The 2022 onward are H-100s.
We’re going to add all these up, and here’s why. They’re expensive. You don’t just throw them away when something new comes out. They all stay in operation in some form or fashion. All these are going to be A100s or H-100s. So that’s 12.78 million GPUs sold to industrial data centers.
With export restrictions, especially to China, China and Taiwan make up about half of Nvidia sales. Export restrictions started in 2022 and have ramped up over the years. Nvidia in their earnings say around 40% of Nvidia sales are U.S. data sales. So say maybe half of those GPUs are in U.S. data centers—make it an even 6 million GPUs, a little less than half.
Every Nvidia GPU, when we talk about a GPU, is actually a big server appliance. It’s like the size of a desk, and inside are eight cores. These are processing cores, like your phone has a number of cores. Your laptop has a number of cores. These are the actual CPUs—well, GPUs. Every Nvidia GPU is actually an eight core blade. And if you look at the product specs, they’ve had eight cores in every GPU since the A100.
That means with 6 million GPUs, multiple times eight, 48 million cores. Here’s why this is important: every core uses 700 watts of electricity. That is just the core of the GPU. So an eight core GPU, one of those big table size things, consumes 5,600 watts of electricity. For comparison, your MacBook Pro consumes 140 watts. So that is an order of magnitude and then some on one of these things.
So just on cores alone, if you add that up—6 million GPUs, eight cores each, 700 watts per core—that’s 33.6 billion watts of electricity that mostly generative AI is using. But we add a twist to this: we don’t use GPU cores, we use GPUs. They all need cooling. They all have heat waste.
Nvidia sells a big appliance called the DGX H100. It’s a pod. It has eight H100 cores in it, and the huge box appliance thing has a peak usage of 10,200 watts. So there’s an overhead power consumption of all the cooling and all the infrastructure of 4,600 watts above and beyond the cores themselves. So 6 million GPUs times 4,600 watts, because we’ve accounted for the cores already, that’s another 27 billion watts.
So the total draw, if these are all on, all being used at 100% usage all the time, is 61.2 billion watts solely for the GPUs. Now, that doesn’t count running the actual data center itself. It doesn’t count HVAC and air conditioning and cooling systems and lights and the coffee machine for the staff. All that is not in here. It’s just the GPUs.
If we convert the watts to kilowatt hours, 61.2 billion watts is 61.2 million kilowatts. And then times the number of hours you care about is kilowatt hours. So if we’re talking energy use per year, there are 8,760 hours per year. So the CPU usage is 536 billion kilowatt hours per year, if you ran them at full tilt all the time, going 100% of the time.
That’s not typically what happens. We don’t know what percentage of GPUs are set aside for regular use, like when you use Chat GPT, and what percent are set aside for training, for making new models. Those GPUs that are focused on training, they will be going full tilt all the time, just running and consuming electricity because they’re under heavy usage.
Those that are being used for inference, aka regular usage—you and me using Chat GPT or whatever—are going to fluctuate throughout the day. They’ll run hard during the workday and less hard when we’re all asleep, assuming that the GPUs in that locale are running.
So if you were to then add up the 142 million households and residential places to live, that amount of electricity is 1.54 trillion kilowatt hours in the USA. By the way, I should have prefaced this is all USA numbers. Your local will vary.
So if you wanted to know how much energy AI could be using at full, go all the way, pedal to the metal, 100% in usage all the time, it could be as much as one-third of U.S. household electricity usage. So it’s using as much energy potentially as one-third of houses in the U.S., which would be one-ninth of all electricity usage. That’s a lot. That’s 11% of all electricity usage. That is not a small number.
Why do we care? Because we care about sustainability. We care about things like having smaller electric bills. We care about not burning enormous amounts of carbon, generating a lot of nuclear waste, or needing to put windmills up on every flat surface possible and solar panels on every flat surface possible to generate power to feed this stuff.
The way forward is with things like the research being done by groups like Meta’s lab, DeepSeek, and Alibaba Cloud, and all the AI labs around the world that are working on making smarter, faster, but more efficient models, particularly the ones coming out of China. Because China has such export restrictions on what GPUs they’re allowed to have, they have much lower power ones than companies in the USA.
That means that they have to come up with novel techniques to squeeze all the power out of the GPUs that they have, and so they make more efficient models. The nice thing is that, as we talked about in the previous video, when the Chinese folks put out DeepSeek, what they did was they gave it away, and they gave away the mathematics and the techniques that they used to make all models more efficient and all models more capable. And hopefully in the spirit of science, other labs will do the same. Western companies tend not to do that a whole lot, with some exceptions, but the big tech companies generally don’t really do that stuff, with the exception being Meta.
But that’s why this matters. There’s an enormous amount of energy at stake, and if we can make AI that is efficient and small and fast, we will consume less power doing it.

In today’s episode, are you wondering what GRPO is and why it’s a game-changer in the world of AI? You’ll discover the revolutionary Group Relative Policy Optimization technique that’s making AI reasoning smarter and more efficient. Learn how this open-source innovation, pioneered by DeepSeek, is leveling the playing field and challenging big tech’s dominance in AI. Tune in to understand why a flexible AI strategy is now more critical than ever.
Mind Readings: Why GRPO Is a Big Deal in Generative AI
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
In this episode, let’s talk about GRPO—group relative policy optimization. It’s a big deal, but what the heck even is it?
GRPO is something that was invented by the folks who made DeepSeek, the DeepSeek reasoning model R1. One of the key findings from the release of DeepSeek was how well and thoroughly it reasoned, thought things through, as you can even watch, just talking it out as you’re running it. The DeepSeek Group achieved this with a mathematical formula and a process called Group Relative Policy Optimization—GRPO—which is just a mouthful.
What is this? Well, in the academic paper they made, they went through all the math, and it’s pretty cool. We’re not going to go through the math because I didn’t do so well in calculus and linear algebra, so I don’t find the mathematical expression particularly helpful.
But here’s an analogy. Imagine you are a chef in the old way of doing things. What you would have done is you would have made a pizza and then sent it to people in the restaurant or wherever, to critics and say, “Hey, judge this. Do you like it? Do you not like it?” And so people will say, “Yeah, I like it” or “No, I don’t like it.” And you go back and try it again. And you do this process a lot back and forth.
Well, most models are reasonably smart. So what DeepSeek did was they said, “You know what, let’s stop asking people. Instead, let’s use the intelligence that we know the chef has.” So imagine now, the same chef wants to make the tastiest pizza possible, but instead of making a pizza and sending it out for reviews, the chef is like, “You know what? I want to taste it myself.”
In fact, I’m not even going to make one. I’m going to make a bunch of pizzas—ten pizzas, different toppings, different dough, and stuff—and see which one I like. And then I’m going to throw away the ones I don’t like, and then I’m going to make revisions and new versions of the ones I really like. And because the chef is pretty smart, the chef understands what they’re doing, the chef knows, “Yeah, that pizza didn’t turn out well. Hey, using a crust made entirely of sand didn’t work out that well.”
And so what GRPO does is it behaves like that chef. In the training for the model, and how the model is made, it’s doing its own taste tests. It’s doing its own preference checks. And critically, instead of sending it out every single time, it only sends it out at the end. It’s like, “I’ve made the right pizza. This is the pizza for you.” And then you, the user, taste it and go, “That actually was really good pizza.” Or you’re like, “No, not really.”
But because you’ve cut down the feedback loop so much, GRPO is much more efficient and way more effective for models to do reasoning, to talk through what it is that they’re doing.
Now, here’s where this gets interesting. Because they released all the math, labs around the world have been trying out GRPO and finding great success with it. In the open models community, the community of people who can download these models for free, groups like Unslauth, which is a fun name, have found that they can tune any open model with GRPO with very small amounts of computational power.
What does this mean? It means the power of what makes DeepSeek special can be brought to nearly any AI model out there, the ones that already exist in any form, and there are 1.39 million of them as of the time of this recording.
I would not be surprised if the big tech companies were scrambling to implement it into their future models, but the tech to refine your own models is available for free today. That’s the power of open models. When a company comes up with something, they release it openly to the public. Everybody benefits.
So what? Why do we care? DeepSeek’s reveal of GRPO and giving away the methodology makes better AI for everybody. Unlike certain big tech companies, like, “Oh, our model is superior. We’re not going to tell you about it.” No. Everybody benefits from this mathematical formula. It makes models that are much smarter at a very low cost, which means that reasoning models are no longer the domain of big tech. Instead, it dramatically accelerates the usefulness of AI by reducing hallucinations and errors from models of any size, even tiny ones.
This is good for us, right? The users of AI, the people who use AI. It’s really bad for the big tech companies that were hoping reasoning models would be a competitive advantage to lock in customers. Now, any gamer with a decent rig in their basement can make a great reasoning model at home for just the cost of electricity and not being able to play Call of Duty for a few days.
This is why you hear so much in Silicon Valley press and the media about why people are trying to create as much fear as possible about DeepSeek. Now, to be clear, the Chinese hosted version, deepseek.com, and the app, which you can get in the app stores, absolutely sends your data overseas to China. Let’s be clear about that. Your data is not private. It says so in the terms of service. It says so in the privacy policy. We are using your data. That part is 100% true. They tell you that. We’re using your data. Absolutely never use their hosted version for sensitive data.
But all the people trying to trash the overall reputation or dissuade people from using it or exploring it, they have a vested financial interest in not seeing the crown jewels be given away for free to everybody. So there’s a little bit of selfishness in some of the fear, uncertainty, and doubt that big tech companies in the West are spreading.
That doesn’t mean you should just go use the Chinese hosted one if you are talking sensitive data, but it does mean, for example, the hosted version that you download and host in your company’s servers or rent from a service provider in your country, that is safe to use, and it’s state of the art.
Increasingly, AI is beginning to look like the open source world, where software like Apache, MySQL, Linux, and other major open source projects will be freely available. Companies that derive value from the ecosystem will be doing so with services to administer the software, but the software itself won’t be any kind of competitive advantage.
AI will not be a competitive advantage when you have such great models available for free on pretty much any hardware. That’s a good thing, and there’s still plenty of room for people to make plenty of money. The company Red Hat made billions of dollars on Linux hosting. They didn’t control Linux. They contributed to it, but it’s a free operating system that anyone can download. But a lot of companies say, “Hey, we want someone to take the blame if things don’t work well.” And that’s what Red Hat did, and that’s why they were so successful that IBM bought them for billions of dollars.
So this means for you and me, our AI strategy should be incredibly flexible. Do not lock into any one vendor or any one technology. Lock instead into a strategy and swap vendors and models as needed for the best results available at any given time. When big labs like DeepSeek release their stuff, their models, great. Be ready to switch immediately to something new. Don’t have loyalty to the technology, have loyalty to your process, your purpose, and your goals.
