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.
