Mind Readings: DeepSeek Week Part 2 – Understanding the Different DeepSeek Versions
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
Welcome to Part 2 of Deep Seek Week, if you will, on the channel here and on the blog. In the first part, we talked about why Deep Seek is such a big deal, why everyone’s paying so much attention to it. Today, we’re going to talk about the different versions that are available to you and me and the kind of results that we get out of them. So there’s going to be three different flavors of the Deep Seek technology. There is V3, which is their chat model, which is the equivalent of Chat GPT’s GPT-4. All you talk to it, you know how to use it, you’ve used Chat GPT forever, it’s the same exact thing. There is R1, their reasoning model, which is the advanced thinking model, and then they have these distilled models that they’ve made of other high-performing AI models they tuned with their processes. These three sort of, I guess, categories are what’s available to us, and we can run them in a bunch of different ways.
This is something that makes Deep Seek very different than Chat GPT or Google’s Gemini or Anthropic Claude. With those companies, you have to use their services. You cannot run Google Gemini on your own computer. You cannot download Open AI’s 01. With Deep Seek, you can use their services, which are provided through their company’s website and stuff like that. And we’ll talk in the next part about whether that’s a good idea or not. But you can, if you have the hardware, you can download and run these things yourself. So let’s briefly take a look at the way it performs, and we’re going to use their interface to start. Now I do want to emphasize, read the privacy policy because it is very permissive for them, which means that your data is going to be going to be used. So just being aware of that, that is, that’s what’s going on here. Let’s start with aβlet’s start with a standard prompt.
I’m going to have Deep Seek, the straight, the straight chat version, compose some song lyrics. I’ve got a very long prompt here that says we’re going to write a song about social media, X threads, and Blue Sky, and so on and so forth. Actually, I’m going to make a quick modification to this. So we’ve got our long, our guidance for lyrics. Let’s see how Deep Seek itself performs. This is going to be the V3 chat. So it’s got, it’s no different than GPT-4, which means that you’re prompting. I’m using a fairly naive prompt because I just want to see if we can make a fun song about Blue Sky. And I came up with decent, pretty decent scrolling through the cast, it’s a little fight. Elon’s got the Nazis and Zucker’s got the right. Threads is just an echo where the same thoughts repeat, Blue Sky’s got the vibe. It’s a retro tweet treat. That’d be a tough to say. But it did a pretty credible job there.
Now, let’s take that exact same prompt, start in your chat. I’m going to turn on reasoning mode. So this turns, switches it from V3 to R1, their reasoning model. Let’s see what happens with this. We give it that. And now it starts to do chain of thought aloud. So it’s saying, hey, I think I need to start doing this. I need to be, it needs to be this. I’ll break down the key elements. This is what this means. These are the jabs. And it comes out with, just quickly eyeballing this, a better result. Elon’s X marks a spot where brain cells decay, a rocket man tweeting, I don’t know, mean display while Tony Stark cosplay runs. Oh, man. It did a decent job. I can scroll clearly now. The trash is rinsed out. That’s, that’s, okay, that’s pretty darn good. So this is R1.
You can see that what R1 did was it took some time to basically sort of have a meeting with itself to come up with some options before spitting out its output. This is, this is pretty darn good. Now, the third model that we’d want to use is we’re going to use one of the Meta-Llama models, but we’re going to use the one that Deep Seek tuned. So this is one that runs on your computer if your computer has enough memory. So I’m running a MacBook M4 with 120 gigabytes of RAM. This model occupies about 50 gigabytes of memory for the model itself. Plus, it requires five or six gigabytes for the context window. So we can see already just on what’s doing. It’s got its own chain of thought. So it’s saying, here’s what I think I need to do. And now I’m going to start doing the thing.
This is obviously, you can see also considerably slower, but because this is locally hosted, it is completely private. So if I put this to the side here, we can actually see the Llama, the Deep Seek version of Llama churning away, trying to figure out what words, what probabilities to do. So it’s going through this chain of thought first and then we’ll assemble the lyrics. So it’s not much different procedurally from this version of Deep Seek, where you could see the chain of thought. This version, because it’s a much larger model, is capable of more advanced thought, more thorough thought. But this is still not bad. So let’s wait for this to finish up. So what you’re seeing here from the Llama version that Deep Seek tuned is not bad.
I would rate its performance roughly on par with maybe GPT-4 or maybe the previous version, GPT-4V. It’s not as good. You can tell just from a purely qualitative perspective, it’s not quite as good as the more advanced model, but that’s expected from a model that you can run on your laptop as opposed to a model that requires a data center. So these are the versions of Deep Seek that are available to us. Again, if you have the hardware, and for running V3 or R1, you need a lot of hardware. When Nvidia’s project digits come up, the 3,000 computer that has 120 gig of shared memory, you’re going to need three of them tied together, which it can do to run Deep Seek R1 locally.
However, that would give you state-of-the-art high-speed output for under 10 grand, which for a small to mid-sized business is reasonable. It’s not great, but it’s reasonable for a large enterprise. It’s terrific. And for anyone who wanted state-of-the-art performance, I mean, that’s a lot cheaper than buying in an H-200 at50,000. So those are the versions that are available to you. Now, you’ll note that the web version doesn’t require anything other than for you to create an account and log in. The downloadable versions do require extra effort to put together, but the trade-off is that a downloadable version that you’re running is completely private. You can do whatever you want. And there’s no difference between that and any other app that’s on your computer that doesn’t call home. So I think that’s a great place to stop because we want to transition into part three, which is, is Deep Seek safe, especially given some of the hype that’s being discussed right now. So we’ll come back and talk about that in the next part, until see you then.

Mind Readings: DeepSeek Week Part 1 – Why Is Everyone Talking About DeepSeek?
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
This week, we’re going to talk about DeepSeek. We can go deep on DeepSeek, the parts, the puns, and why everyone’s talking about it. What makes it good and specifically which versions, if any, you should be using, and whether it’s safeβall the questions that you have about this very, very interesting family of models that has been around for some time, but people are just figuring out now that it exists.
So, let’s dig in. In today’s episode, we’re going to talk about why is everyone talking about DeepSeek? What is this thing? DeepSeek is a Chinese companyβa Chinese technology companyβthat, like many other companies from the world, makes artificial intelligence models, AI models. They make language models. So, their versions, they currently have two major flagship versions: V3, which is their regular chat version. The equivalent in OpenAI would be OpenAI, uh, GPT 4.0, which is the stock model that people use, ChatGPT. Another equivalent would be something like Google’s Gemini Pro. And then they have R1. R1 is their reasoning model that thinks things through and is great for complex tasks.
Again, in the Western branded AI models, OpenAI’s O1 model is a reasoning model. Google’s Gemini 2 Flash thinking is a reasoning model. These are some of the bigger, better-known reasoning models. Why is this particular model, in particular R1, getting everyone’s attention? It comes down to two things: quality and price. In the released versions of DeepSeek V3 and R1, the quality is almost as good as or better than Western counterparts.
So, let me bring upβI need to reset my screen here. Let’s go ahead and do that. There we go. We see here the quality versus price analysis. This is from artificial analysis.a.i. And we see here, there’s OpenAI’s 01. The quality scoreβthe average quality score to choose on most benchmarksβis 90.3. And the cost per million tokens is 26 per million tokens. Then over here is 0.1 mini. Its quality is 83.6, and its cost is5.25. Claude Sonnet 3.5, the most current version of Claude, has a quality score of 80 and a cost of 6 per set of tokens.
I think I need to turn on Google’s Gemini. I don’t have Gemini. Let’s turn on Gemini Pro and Flash so we can see them. We see Gemini Pro here at 80.4; it’s neck and neck with Claude, and it’s a cost of2.19 for Pro. For Gemini Flash, that is 13 cents per million tokens. Quality is 74. Meta’s Lama 3.3, a score of 74 in quality, 67 cents per million tokens. OpenAI’s GPT40, the stock model, a quality score of 73.1, and a cost of 4.38. Then we get to DeepSeek. DeepSeek reasoning model, R1,2.88 centsβno, I’m sorry, 2 per million tokens, 88.8 score. So it is on par with 01, but look at that cost difference:26, 2,2.2. So, this is more than 10 times more expensive than R1 for about the same quality.
If you look at DeepSeek V3, 90 cents per million tokens, a quality score of 7.9.1. Compare that to OpenAI’s 4.38. So, we’re talking, what, almost five times more expensive for higher quality. This is why everyone was talking about DeepSeek, because its models are incredibly powerful and stupid cheap in their API. And, rightfully, a lot of people saying, what happened there? Well, the folks at DeepSeek essentially told everyone, they said, “Here’s what we did.” And there’s a paper out called “DeepSeek R1” that explains the process that they used to make these models, and you can download this on their website.
It is a fair technical paper. The secret sauce for DeepSeek is twofold. Number one, they’re using an architecture that’s very efficient. The architecture is called Mixture of Experts. Google’s Gemini is also a mixture of expert model, which is different than what’s called a dense model, like ChatGPT’s GP4. So, it is a very, very, very sprightly and efficient model. And the way that they built this is wildly different than the way other model makers have made models in the past. And it comes down to two things: reinforcement learning and what’s called GRPO. According to the paper, GRPO is group relative policy optimization, which is a reinforcement learning algorithm that does not have a separate model for the reinforcement learning that’s built right into the main model. So, this dramatically cuts down training costs.
Here’s a way to think about how these two thingsβthese two modelsβare different. Like, OpenAI’s and the Western models versus what DeepSeek did. If we think of them as kitchens, in O1 or Gemini or Claude, think of the trainingβthe chefs thereβin very classical fashion. You go through culinary school, and you spend years on, you know, being an apprentice and then a sous chef and chopping up things for and fetching coffee for the executive chef. And eventually, after a lot of time and a lot of money and a lot of effort, you end up with a Michelin-starred chef, right? That would be the way that traditional models work. DeepSeek used reinforcement learning from the beginning rather than supervised fine tuning. When they’re in the restaurant analogy, they gave the chefs basic skills and then said, “Guess what? You’re going to learn how toβhow to cook the hard way.” Well, we would think of it the hard way. You’re just going to do stuff, and we’re going to correct you along the way. And so, it’s a much moreβI guess you would call itβintuitive way to learn how to cook, whereas you’re not, you know, digesting huge textbooks of how to cook. Instead, you’re learning through experience how to cook. What they did, in terms of producing the model, this creates a much more capable model because it spends all of its time learning what to do and what not to do through experience rather than sets of rules. So, this approach is very, very different, and that’s what makes it so good and what makes it so cheap.
By doing it this way, they dramatically cut down on the compute costs, which is important because one of the things that the government of China, the People’s Republic of China, has against it is export restrictions. A lot of the top-tier AI chips that are produced in countries like America and other places in the world that are super technical economies, like Taiwan, for example, China can’t buy them. China can’t get a hold of them. And as a result, Chinese AI labs have to figure out how to make the most of the hardware that they have. And so, through using this group resource policy optimization, they’re essentially saying, “We’re going to figure out how to make this model incredibly inexpensive to operate and lightweight because we don’t have a choice. We don’t have the biggest, beefiest, nicest hardware.”
It’s again, imagine back to the kitchens. You have one kitchen that is all Viking appliances, and it’s super high-end. And then you have one kitchen that is maybe not the high-end appliances. The appliances in the kitchen still work. They’re still good. It’s not like you’re cooking, you know, with stuff made of random parts found on the side of the road. It’s still good. It’s just, it’s like Hamilton Beach, right? It’s the cheaper equipment. When you learn to cook in an environment like that, you learn to make the most of what you have. And that’s why DeepSeek is so efficient and effective.
The other thing that has talking quite a bit is that DeepSeek just gave away the model. They put it up on Hugging Face, which is where pretty much everyone who’s a model maker puts their stuff when they want to give it away. And the rest of the world can take it and run with it, which is pretty amazing that they can do that. It has caused such a stir in Silicon Valley. If you go into apps like Blind, which is sort of the tech water cooler gossip, pretty much all of Silicon Valley is losing their craft because DeepSeek has come out with a high-performance model that meets state of the art that is way cheaper, and they get it in a way. So, if you wanted to, if you had the hardware to support it, you could run it yourself, and it would do well.
They also demonstrated their techniques, which I thought was very clever, on existing models. So, if you were to go into their repository on Hugging Face, you’ll find not only do they have their model up there, but then they’ve taken other models like Quinn and Lama and tuned them using their processes to create these distilled models that, in the case of Lama 70B, have chart-topping scores. So, they took an already good model and turned it into a world-class model with very, very little resources. So, that’s pretty darn amazing. And, again, everyone in the Western tech community is kind of losing it because it kind of invalidates a lot of the hype and the tech bros and the tech oligarchs talking about how about they need all this energy and all this money, and they need a500 billion project. And this Chinese firm was like, “No, you don’t. Here, state of the art, we did it on the equivalent of driving a Volvo, and you’re saying you need a Bugatti. You don’t need a Bugatti to get world-class performance. You can do it in a Volvo.” And that’s what’s happened.
So, this is part one on why everyone is talking about this thing. In the next part, we’re going to look at the different versions and see what’s available. So, stay tuned for that.

What’s On My Mind: Introduction to Reasoning AI Models
This week, let’s talk about reasoning models, as they’re all the rage at the moment. What is a reasoning model? How is it different from regular AI? Why do we care? We’ll answer all this and then some, so buckle your seat belt, unplug the popcorn machine, and let’s get started.
The Age of Reason
“c. 1400, resounen, “to question (someone),” also “to challenge,” from Old French resoner”
AI – language models in particular – perform better the more they talk, like sportscasters and YouTubers. We discussed why this is the case in a previous issue, but the very short version is that the more they talk, the more they can zero in on the right answer. The statistical nature of a language model is that the more talking there is, the more relevant words there are to correctly guess the next word.
For most of the first two years of generative AI, AI models relied on us to tell them to talk more. For anyone who’s been using generative AI for longer than a hot minute, you probably know one of the foundation princples of prompting: chain of thought. This is when we tell the model to think step by step, or explain things step by step.
This works, of course, by getting the model to say more relevant words.
Another foundational principle that you’ve probably learned (and if you haven’t, sign up for my new paid course, Mastering Prompt Engineering for Marketers) is reflection prompting, where we tell a model to take a step back and think things over. We do this when it’s not getting the point.
And a third principle is the reward function. You’ll see this written out often in the form of things like scores, scorecards, etc. where we ask AI models to score their efforts, or to keep a running score of things they’ve done well or poorly.
These three core components – chain of thought, reflection, and reward functions – have been part of prompt engineers’ toolkits almost since the beginning of generative AI, and certainly once advanced models like GPT-4 came out at the end of 2023.
Yet most people don’t use them. Most people don’t even know they exist, despite how much of an impact they make on model performance and the results they generate.
So what companies like OpenAI, Alibaba Cloud, Google, and Deepseek figured out was to make models do this automatically – thus creating a class of language models called reasoning models.
Reasoning models fit the etymology of reason perfectly – they question and challenge themselves. Is this the right idea? Is this what the user wants? Are we getting closer to the stated purpose or not? What should we do to achieve the tasks the user has set out for us?
Here’s a key thing to remember, however. Reasoning models are still transformers-based, attention-based large language models. Even though they display impressive capabilities at self-reflection and self-correction, even though we may anthropomorphize them as they work, they are still fundamentally the same architecture as we’ve been using all along. The basic rules haven’t changed, rules like using more relevant, specific words in our prompts.
Why Reason?
Reasoning models are important because so many of us don’t do any reasoning of our own when we use generative AI. We collectively tend to treat generative AI like it’s a genie from fairy tales, that it can somehow magically read our minds and create what we want without us having to work very hard to be specific.
Model makers realized that, two years into the Intelligence Revolution, people are still feeding them prompts like “Write a blog post about B2B marketing and make it interesting” (I kid you not, I saw someone actually do that) – and still getting generic, low quality outputs. The more people who use generative AI badly, the harder it is for the technology as a whole to get traction.
Hence, model makers have spent heavily building reasoning models to try patching what’s fundamentally a human flaw. A reasoning model in general will give better, higher quality answers to questions than a non-reasoning model, especially if the initial prompt isn’t terribly robust.
For us in our day to day jobs, reasoning models are a great choice for complex tasks. They’re not a great choice for simple tasks because they’re incredibly compute intensive; if you’re worried about sustainability, reasoning models consume anywhere from 2x – 10x the power and resources per query of non-reasoning models.
We can see this in charts like this one from Artificial Analysis:
OpenAI o1 cost per 1M tokens: $26.25
OpenAI GPT-4o cost per 1M tokens: $4.38
Deepseek R1 cost per 1M tokens: $2.88
Deepseek V3 cost per 1M tokens: $0.90
Incidentally, this chart is why all the big AI tech vendors in the West are in a panic this week. Deepseek’s models are top tier in performance while being bargain basement in terms of cost, and are freely available to download if you have the infrastructure to support them. Deepseek’s reasoning model is 48% less expensive than OpenAI’s non-reasoning model, and 89% less expensive than their reasoning model.
So what’s a simple or complex task? If we go back to the core use case categories of generative AI, tasks like summarization, extracting, rewriting, and classification tend to be relatively simple tasks. A prompt like “summarize this email’s key points” is a task that even the least powerful AI models are quite capable of handling. Using a reasoning model on this task would be overkill.
On the other hand, if we ask a model to take in a big pile of information and build a SWOT analysis, then recommend a business strategy from that? That’s definitely a reasoning task. It’s complex, multi-step, and requires a lot of thinking.
How Do We Start Reasoning?
Once we’ve figured out whether a task is a reasoning task or not, we then have to start prompting the reasoning model. Reasoning model prompts are different than regular AI prompts; critically, things like “think about this step by step” should be absent because the model already knows to do that.
Problem (or purpose): state what it is you’re trying to achieve
Relevant Information: give lots of context, background information, etc. to help the reasoning model know what it’s doing
Success Measures: what does success look like, and how does the model know it’s succeeded?
In many ways, this is the front half of the Trust Insights RAPPEL framework; but instead of us having to do the step by step thinking, the model does that part.
I compare reasoning models and non-reasoning models like this. A non-reasoning model is like the world’s smartest, most forgetful intern. You need to provide a ton of information, explain the task and how to do it clearly, and guide it. A reasoning model is like the world’s smartest, most forgetful junior manager. They don’t need to be told how to do a task – they figure that part out for themselves. But they absolutely still need robust amounts of information about what they’re doing, why they’re doing it, and how to know when they’ve succeeded.
Let’s look at a couple of examples of how a non-reasoning versus a reasoning prompt might look.
A non-reasoning prompt might go like this: “Role: You’re a world-famous email marketing expert.
Action: Today, you’ll be writing a 500 word blog post on the importance of deliverability protocols like SPF, DKIM, DMARC, and BIMI in email marketing.
Prime: First, answer these questions:
– What are best practices for implementation of SPF, DKIM, DMARC, and BIMI? Talk this through, step by step.
– What are common mistakes made by less experienced email marketers when it comes to delivery protocols? Talk this through, step by step.
– What are expert tips and tricks for implementing email deliverability protocols? Talk this through, step by step.
Prompt: Then start drafting the article. Talk about what each protocol is, why it matters to the marketer, and how they should get started. Be clear and include examples and analogies so that people don’t get confused. Use only one bulleted list in your response, and only if it’s appropriate.”
What would the same prompt look like for a reasoning model?
“Problem: Marketers are getting stuck in spam because their email marketing hasn’t implemented deliverability protocols.
Relevant Information: You’re a world-famous email marketing expert. Today, you’ll be writing a 500 word blog post on the importance of deliverability protocols like SPF, DKIM, DMARC, and BIMI in email marketing. Explore best practices, common mistakes, and expert tips for deliverability protocols. Talk about what each protocol is, why it matters to the marketer, and how to get started.
Success Measures: Your blog post should be 500 words, +/- 2%. Your post should be in non-technical, action-oriented language to help the reader know what to do after they’ve read the blog post. Be clear and include examples and analogies so people don’t get confused. Use only one bulleted list in your response if appropriate.”
Can you see the difference? There’s much less “do this, then this” in the reasoning prompt. It’s guidance that you would give a junior manager, not an intern – the manager will figure out how to make it happen, but you need to tell the manager what needs to be done, why, and what success looks like.
Here’s your homework assignment. In the model of your choice – Gemini Flash 2 and Flash 2 Thinking, Deepseek V3 and R1, OpenAI GPT-4o and o1 – test these two prompts for yourself. See what the output looks like from each non-reasoning and reasoning model, along with the way the models think aloud.
Then do this for some of your favorite prompts. See how they each run in comparable reasoning and non-reasoning models to see the difference.
Wrapping Up: Reason is the Foundation
In general, for the same complex task, reasoning models perform better than non-reasoning models – and the three state of the the art foundation models on the market right now, OpenAI o1, Gemini Flash 2 Thinking, and Deepseek R1 – all behave differently. They have very different infrastructure and their models were assembled differently. (for the uber-technical, it’s assumed o1 is a dense model, whereas Gemini and R1 are MoEs, and R1 was trained almost exclusively with RL whereas the others are assumed to be SFT trained)
What are the kinds of tasks you’d hand to a reasoning model? Again, think about the intern versus junior manager analogy. There are some tasks you can confidently hand to the intern. There are other tasks you’d probably prefer to hand to someone a little more experienced. Whatever those tasks are, that’s how to divide them up. Having the intern transcribe and summarize is a good fit. Having the intern anaylze the psychographics of your ideal customer is less of a good fit than handing that to someone more senior.
And reasoning models are a powerful fit for the next generation of AI agents. This week, I built a clone of OpenAI’s Operator using the Browser Use library in Python, combined with Google’s Gemini 2 Flash Thinking. Having an AI agent that can control a browser is powerful and compelling – but it needs a heavy duty AI model on the back end that can think things through, especially when dealing with complicated user interfaces like websites.
Once you understand what reasoning models can do and how powerful they are, you’ll be well on your way to harnessing their power for complex tasks.

Mind Readings: How Generative AI Models Work Inside, Part 5
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
In this fifth and final part, we’re going to take a look at the lessons we have learned from this crazy visualization of what happens inside generative AI, from the moment we give it a prompt, all through the process of tokenization and the embeddings, which you can see here, how the model works, turning words into numbers, turning numbers into statistics, and then doing massive computation on those statistics at every single layer, trying to figure out what the next word in a sequence is going to be. This is what happens under the hood of chat GPT and similar tools. If you were to open up those models and see what was going on inside, this is exactly what would be happening. You can see the output at the very bottom there.
The first four parts, we looked at this like it was a newspaper room, where the editor-in-chief of our newspaper comes into the writer’s room with a story. So, scroll all the way back to the top of this model here. The editor comes in and says, “I’ve got a story.” Then the reporters all figure out, βOkay, we got to figure out who’s doing what and in what order.β Then the reporters go and hit their beats. They come back with all their information. They put it on a big whiteboard with all the red yarn connecting everything, and they make a first draft. That first draft goes to the editors. The editors tune it up, say, “Get rid of the unimportant stuff. Try to figure out what the most important stuff is.” They show it to the editor-in-chief. He loves it, and he says, “But I want more. Go back out and hit your beats.” This process goes on for many, many, many times in a row until you get to the very bottom. We have a final draft, and then the model assembles the final draft and spits that out. The newspaper room spits out the story. That’s conceptually what’s going on here.
Now, we’ve talked about all these stages and what they mean in a very loose analogy, a very rough analogy. What does this tell us, though? How do we make use of this information? Because it’s cool. It’s cool to understand how prompts, how AI models work. What do we learn from it? So at the very, very top, the first thing we need to remember is that instructions matter. The editor-in-chief needs to provide very clear guidance to say, you know, not just, “I want you guys to write a story,” but to say, “I want to do a story on corruption at the docks in the Port of Long Beach. Daew Industries is a shell company for the Busan Mafia out of South Korea, and I want a story about what the bad things they’re all shipping in.” This is all fictional, by the way. That is a lot more clear. The reporters will be able to figure out who they need to go talk to, what questions they need to ask, what information they need to come back with. So the more relevant, specific information that the editor-in-chief can provideβand the editor-in-chief is us in this analogyβthe better results we’re going to get.
The second part is in the writer’s room, when they’re going out to the reporters who are going to get information. Again, if we provide more information up front, the reporters have to go out and get less, right? So the more context we can provide, the less the reporters have to go hunting. That’s why prompts like summarization can be two sentences long. Prompts like writing in our style could be 20 pages long if we want the AI to do what our desired output is. The more context we provide, the less work the reporters have to do.
When we choose, when we talk about how to get these things to obey, we want to set things like style and tone and all the instructions that the multi-layer perceptron model uses to refine. So we want to give examples of, “Here’s exactly how to write. Here’s the length. Here’s the number of words. The words you should use. The words you shouldn’t use.” All of those instructions help the model to understand, “I know what I’m supposed to be doing,” which is really, really important because if you don’t do that, it’s like the newspaper, just sitting there going, “I don’t know what to write. I’m kind of confused.”
That’s why when we do prompt frameworks, I’ll bring up the Trust Insights REPEL framework, which you get at Trust Insights dot AI slash rappel, R-A-P-P-E-L. First thing up is role. Tell the model who it is. “You’re an award-winning journalist.” Those words that we use in the role are kind of like the editor-in-chief, telling which writers are on deck. The action: what are you going to do? This is, again, helping the reporters understand who is on deck, what they’re going to be doing. Priming is all that context, all that information that we want the reporters to have, so they have to do less grunt work out in the field, less footwork. The prompt is the instructions. Evaluation is us determining if the model output is good, and then learning is encoding it into a task so that we can repeat it in the future. This prompt framework, and there are many prompt frameworks, but this one we developed because it embeds a lot of advanced knowledge of how the AI system works under the hood into the prompt structure, so that you don’t have to know every step of the way what’s going on inside the model and why it’s making the choices it’s making.
That’s, by the way, is one of the things that kind of drives me nuts about some of what I see on places like LinkedIn, people saying, “Oh, nobody knows what’s going on inside AI. It’s a big black box.” Not really. We know what’s going on inside. We know how the mechanisms work. The fact is that it’s so technical and so filled with mathematics that, for a lot of people, that is opaque, right? If we talk about dot products between query, key, value vectors, yeah, that is, that may as well be a black box because a lot of people don’t have the mathematical background to know what that means. But it doesn’t mean we are ignorant of what’s happening inside the model. We just can’t convert that technical knowledge into practical knowledge we can use to make our products better.
The whole dot product and query key value multiplication thing, that, for example, tells us, “Avoid junk in our prompts. Don’t include bad data. Don’t include irrelevant data.” If you’re doing conversation mining, for example, maybe you want to mine Reddit for some insights, the more junk you can get rid of, you know, the more LOL and the posts that say, “First,” you know, that one guy, it’s almost always a guy, who just comments first or, you know, “Nice try, ditty” on every post, you want to get rid of that stuff because that’s not helping. That adds more junk in that writer’s room portion of the model, and as a result, the reporters have to work harder. Then the editors have to work harder to get rid of it to go, “Well, why? Who brought this sticky note even into the room? Like, this should not have been brought into the room.” So the more cleaning we can do of our data up front when we provide context, the better results we’re going to get out of AI.
So I hope this tour of the blood and guts of a generative AI model is useful to you now in helping understand what’s happening behind the scenes. If you were to open up chat GPT and look inside, this is the mechanics of what would be happening, albeit at a much larger scale and much, much faster. Taking this knowledge then and turning it into things like more specifics, more context, more relevant stuff, cleaning your data to get rid of junk before you put it in, all of those things help make the model work better. We talked about where in the model each of these things happens. The more clean and clear you can be going in, the better the results you’re going to get coming out. The more specific the instructions are that you give, the easier it is for the editor’s room, the multi-layer perceptron, to refine and choose the data that it’s going to output into the subsequent stages in the model.
You don’t need to know the mechanics to use AI well. But when AI does something that you don’t expect or that you don’t want, knowing the mechanics can help to go, βOkay, well, maybe I’ve got bad data or wrong data or irrelevant data. Maybe I’ve got conflicting instructions in my prompts.β You might say, βBe verbose,β in one section, and another section, βBe concise,β and the model’s like, “I don’t know which you want me to be.” All of that conditions the responses. Knowing how it works will help you be more thoughtful and more intentional in your use of AI. Thanks for tuning in. Talk to you next time.

In today’s episode, I bring you part four of my series, revealing the intricate process of how generative AI models produce coherent text, one word at a time. You’ll learn how the final stages, from the refined draft to the actual output you see, involve a computationally intensive process similar to printing a newspaper one word at a time. You’ll gain insights into why specificity in your prompts is crucial and how this understanding can dramatically improve your interaction with AI. This knowledge helps you understand why generative AI is so powerful and resource-intensive!
Mind Readings: How Generative AI Models Work Inside, Part 4
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
Welcome back. This is part four in our series of how generative AI models workβthe bloody guts, the highly technical deep dive into these thingsβinspired by some comments in the CMI Slack group. In part one, we talked about tokenization, embedding, and vectors. This is, in our analogy of a newspaper, the editor-in-chief runs in with a story, hands out assignments to all the reporters, and the reporters figure out who’s going to do what and in what order. Then they come up with a project plan, which is the input embedding here.
So we’re at the very top of the story here. The editor comes in, reporters go figure out who’s doing what, they figure out what order, and they come with a project plan. Then the reporters go out, and they hit their beats. They make a list of all the questions they need to ask. They make a list of who they need to talk to, and they make a list of what information they get from their sources. Then those reporters get together in an editing room, in a writing room, and they put all of their Post-it notes and stuff on a big board and get out the red yarn and start making all these connections. That is sort of the attention layer.
Then the rough draft of that is handed off to the editing room. The editor’s room has their style guide and looks at all of what the reporters submitted. They go through it, and they tune it. They say, βLike, this is relevant, this is relevant, this is okay.β Then they end up with a refined version of the story. The editor-in-chief takes a look so far and goes, βI love this, I love this is, I love this is going, but I need more.β Go back out and hit the beat, and get me more data. So the reporters and the editors do this over and over again through this long process to keep refining this story until we get to a final draft.
That’s where we are today. This layer norm is sort of the final draft of the story, where the reporters, the writers, the editors, and the editor-in-chief all have reviewed all the different drafts that the story has been through, and they end up with a final draft here. Then what ends up happening after this step is the typesetters and the printers put the actual ink on the paper. At the newspaper, in this case, in our analogy, in a generative AI model like chat GPT, this is the phase at which you start seeing output on the screen. When words start appearing on the screen, this layer of the logits and the logit soft max is the final draft, right? It’s word by word the final draft. Our story is appearing now.
What emerges is not a random collection of words, right? It is now a full-on result of whatever we prompted. So if we start with a prompt of, “Write me a blog post about B2B marketing,” what comes out here is a blog post about B2B marketing. As a result, you end up with good output. However, what isn’t really explained in this animation is that this comes out one word at a time, and then the whole story, one word at a time, gets fed back into the very top, and it flows through the whole system over and over again until you get to a final story. This is why generative AI is so computationally expensive, why it is so energy-intensive, because we are essentially predicting a story one word at a time and going through that whole process like a crazy Rube Goldberg machine, one word at a time.
Each word that comes out the bottom gets fed back in, along with everything else it’s been written, to turn it into a story. Imagine a newspaper that had to print one word at a time and then hand that version of paper back to the editor and then keep going, right? How many thousands of pages of paper would you go through just to assemble one story if a newspaper had to work like that? That’s what’s happening behind the scenes in a generative AI model. That’s why they are so expensive, why they take so much more energy and power and computers than any previous form of AI. But that is also why their performance is so much better than previous forms of AI for tasks like writing, because they can see the entirety of the story one word at a time. They can make coherent outputs.
So this walkthrough of what’s happening in the bloody guts of a machine informs a lot of how we should be doing our prompt engineering, how we should be talking to our models. If we go back to the model, I’m going to hit continue here. Let’s go back to the very, very top, and we just sort of play through from that very first step, the tokenization, going to the coming words into numbers, and then doing the embeddings, and turning those words into vectors, and then going through the whole process of the computations to just make a prediction for the next word. You can see how much computer power this requires just to figure out what the next word in a sequence is going to be. In today’s computers, this is still a relatively fast process, but you can see how much more intensive it is.
So some of the lessons that we can learn from this: one, specificity matters. Just like in our story, if the editor-in-chief, if he gives out a bad story, a bad story idea, like, βHey, let’s write an article today, folks,β all the reporters are going to be like, βUh, what should we do?β and the writers are like, βI have no idea.β Everyone comes up with random stuff, and that goes to the big whiteboard, and the editor is like, βUh, I guess we’re going to try and write a story about something.β What comes out is bad. If the editor-in-chief says, βWe are doing a story on corruption at the, in the ports, at Long Beach. We’re specifically going to be looking at Daew Industries, and how the Busan mafia from Korea is smuggling bad things into the port of Long Beach,β that assignment is so much more specific. The reporters are like, “Got it. I know where to go for that information. I know who to talk to. I know who to buy lunch for.” What comes back is a better story.
Knowing that is how the models work, stage by stage, means that we can prompt better. We know that we should be doing some pretty basic things. Actually, you know, let’s say that for the next episode. So we’ll wrap up with how each part of the model interacts with our prompts. So stay tuned for that.

Mind Readings: How Generative AI Models Work Inside, Part 3
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
This is part three in our series of the blood and guts, the inner workings of a language model, of a generative AI model. Let’s recap where we have been so far using the Bycroft visualization. We have covered, in part one, tokenization and embedding. In part two, we talked about query key value weights and the attention window. This is part three, where we’re going to be talking about multi-layer perceptrons. The analogy, the framework that we are using, is that of a newspaper room.
So in part one, the editor-in-chief runs in with a big assignment. We’re investigating corruption at the docks in Long Beach, and the editor hands out assignments to all the different writers and reporters. They all go out. They figure out who’s doing what and how it relates to the overall story. Then they all hit their beats, and they come back. They have a list of questions they need answers to. They know who to talk to. They go and get the information. They come back. Then all of the reporters and writers get together, big whiteboard, and they start assembling all the Post-it notes from all the notes. What they end up with at the end of this process is that rough draft. The attention residual is sort of the rough draft of the story.
Now, what happens next? What happens next is the rough draft of the story needs to be put through a multi-layer perceptron, which is a very family piece of machine learning technology, but what it really does in the context of a story is it’s editors. So the writers put together a great first draft, and the editors are like, βBoy, there’s a whole bunch of stuff. It’s poorly written. That doesn’t make sense. That’s grammatically not correct. We need to fix this up.β So the first thing that we start with is that multi-layer perceptron bias. The bias is sort of the style, right? So if you’re the New York Times, you have a writing style. You have a style guide. If you are the LA Times, you have a different style guide. If you are some influencer on YouTube, you have your own style. So you start with that.
Then what happens is the editors then take that style, and they look at all of that huge first draft that the reporters and writers put together, and they start making decisions. They start saying, βWell, this is an interesting part of the story. This is not an interesting part. This is salacious. Let’s make sure we include that. This is boring. No one wants to see accounting, you know, shipping manifests in our story.β They go through this process of refining the story over and over again. The activation layer here is the editor saying, βLet’s change synonyms, improve the flow. Let’s move things around. Let’s continue edit.β Then we get to the projection weights here. The projection weights are sort of like a last pass: clarity, consistency, trying to make sure that the story makes a whole lot of sense.
At this point, it then gets tossed into, it becomes a layer norm, which is like a draft of the story. Then in our model example here, the process starts again, right? So you’ve gone, and you’ve done this first draft of the story, and the editors have cleaned up, and it went so well that the editor, too, is like, βMore. I want more of this.β Of course, you repeat the process over and over again. This is what’s happening behind the scenes when you give an AI model a prompt. It’s going through, it’s figuring out what the prompt is, what it means, figuring out what knowledge it needs to look for, where in its own internal database it has that knowledge, and then what that knowledge is. Then it brings it all back, puts it on a big old conceptual whiteboard, and then it sort of self-assesses which of this knowledge is relevant to what the person was prompting me for.
So in part one, we talked about the importance of making sure that we’re using relevant, specific words in our prompts. In part two, we talked about making sure that we’re keeping bad data out of our prompts, you know, irrelevant facts, things that would make the reporter’s job harder. If you give a reporter an irrelevant task to the story you’re writing, they’re going to come back with stuff. It’s a waste of time. In part three, in this editing part, where we see these multilayer perceptrons with the bias, the weights, and the activation layers, this is like being specific in our prompts to say, βHere’s what I want you to do. Here’s how to do it. Here’s your style guide.β If we’re writing, if we’re doing creative writing as a prompt, βHere’s what my writing style is.β If we’re doing strategy, you know, βHere’s the tone of voice you should use.β The multi-layer perceptron’s role as the editor essentially inside the machine is to help condition the output.
If we don’t give it instructions like, “Write in a professional tone of voice,” “Write in a casual tone of voice,” “Write in a hostile tone of voice,” it’s going to try to just do what’s high probability. Again, we’re looking at data in the back end. You’re going to get bland, boring stuff. Why? Because we didn’t give it any guidelines. The part of the model that is the sort of the editor, if you will, doesn’t know what the style is. So it’s going to pick the most common one from its knowledge. It goes and looks at what the reports all submitted and says, “Well, no one gave me a style guide here, so I’m just going to put together an average of what every reporter came back with.” Of course, that sense that you end up with a boring story.
So that’s what we learn from this section of the model, is to understand, “Oh, I need to provide lots of guidance about how the editors should refine what the reporters and the writers came up with,” within our fictional newspaper example of an AI model. If we follow those steps, this, by the way, is why we have things like the Trust Insights RACE framework and PAIR framework and REPEL frameworkβrole, action, prime, prompt, evaluate, learnβbecause knowing the inner workings of the technology guides how we should prompt. The more we have aligned with the way the technology works, the better the results we’re going to get.
So that’s going to do it for this episode. In the next episode, we’re going to talk about putting it all together and what happens next. So stay tuned for that.

In today’s episode, I continue my explanation of how generative AI models function, focusing on the crucial steps following tokenization and embedding. You’ll discover how these models use a process analogous to a team of writers researching and connecting their findings with Post-it notes and red yarn. This is similar to the attention matrix mechanism. You’ll benefit from understanding how this impacts your AI interactions and learn why providing relevant and specific information in your prompts is essential for achieving the best outcomes.
Mind Readings: How Generative AI Models Work Inside, Part 2
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
Welcome back to part two in our series of how the bloody guts of a language model work in AI. In part one, we walked through the whole visualization. We got through this section here of tokenization and embedding, where we talked about the analogy of a newspaper. The editor-in-chief rushes into the writer’s room with an assignment, and the writers all break the assignment up into little pieces. Then they start asking what they know about their piece, and then how does it relate to the rest of the assignment. The priority of the order and that embedding is sort of the project plan for the writers to say, βOkay, now we got to work on the story.β
So from there, let’s go ahead and move into what happens next. So what happens next is the writers have to go and spend some time thinking. What we see in the diagram here is query weights, key weights, and value weights. We have a query bias, key bias, value bias, and then you have the associated vectors and a layer norm. That’s probably a whole bunch of words that mean nothing.
The QKV, query key, and valueβimagine you’re one of the writers in this writer’s room, and you get a small part of this assignment. Maybe you have toβin the previous episode, we were talking about how maybe the editor-in-chief wants an investigation of corruption at the shipping docks in Long Beachβand you are given the part of the assignment that says, βGo to Daew Industries dock and check out what’s coming in on their cargo ships.β
So the writer, you, would sit down and go, βHuh, what do I know about this?β Maybe get out some Post-it notes, and you first write down, βWhat do you know about Daew Industries? What do you know about shipping containers? What do you know about docks?β What do you know about this topic? That’s the query. That is something that gets turned into kind of a set of Post-it notes, if you will.
Then you’ll look at your Post-it notes, and you look at the portion of the assignment you got, and you say, βOkay, well, where might I find information about this?β Then the value part is where you get more Post-it notes out, and you start saying, βWell, I would know, I know where the address of the docks is. I know who runs these docks.β Maybe you do some Googling, and you end up with this big old pile of Post-it notes, right? This huge pile of Post-it notes of all the questions you have, all the places you might go to look for those answers, and then the answers themselves.
What’s happening in the AI model as this is that this whole team of writers is repeating this process over and over again. Everybody is getting out their Post-it notes. They’ve got different colored Post-it notes for different kinds of things. Then in the model itself, when we get to this section hereβthe attention matrix, right, and the projection weights, the attention outputβwhat is happening here is that the writer’s room gets together. Everybody puts their Post-it notes on, you know, a huge wall. Remember that scene from It’s Always Sunny in Philadelphia or the similar scene in Sherlock, where you’ve got the wall of notes and stuff, and there’s red yarn string connecting everything, and all the people are ranting on about the conspiracy? That’s kind of what’s happening here.
So, the editor has given the assignment. The writers have broken up the assignment of the pieces. They’ve all written down what the question is they want to ask, where they might find the information, and then the answers to that. Then everybody gets together and says, βOkay, well, what do we got? Let’s compare notes. What questions are you asking? Where are you going? I’m going to go to the docks. I’m going to go to this company here. I’m going to go to the LAPD.β Then the values of all that information and polling all this information together. What you do then is as everyone’s putting all their notes on the board, you’re getting out the red yarn, right? You’re saying, βWell, okay, I’ve got my sticky notes here. Whose sticky notes are the closest match to mine? Maybe I can share an Uber with Sally because we’re both headed in the same general direction.β
You start putting yarn on all the sticky notes. This is the attention matrix, where you’re trying, where the model is essentially trying to figure out, what of all this content that we have, how does it relate to itself, right? How do we figure out what’s important? Like Bob over there, Bob got a part of the assignment which is, you know, looking at manifest, shipping manifest. Me, I’m going to check out Daew Industries in Long Beach. We’re not really on the same page. So if I’m focused on my assignment, and Bob’s focused on his assignment, we’re not going to have a lot of red yarn between us. As the model starts making decisions, it’s going to keep those things kind of separate.
So after the attention matrix occurs, you’re going to get the sent down here from the attention residual sent down into a layer norm with the MLP, the multilayer perceptron. What’s happening here? Every writer has gone out and gone to their sources, and they’ve all assembled their notes. We got a big old pile of Post-it notes and red yarn everywhere. At this point, we’re now ready to start putting together the story, but the writers aren’t going to do it anymore. Now, it’s going to hand it off to the editing room.
So that’s a good place to stop. To recap, so far what’s happened in our story, the editor-in-chief has come into the writer’s room at our fictional newspaper and said, βHey, I got a story about corruption at the docks.β Hands out the story to all the writers. The writers break it up into pieces. The writers figure out who’s doing what, and how every writer’s piece relates to the rest of the story. Then they all go and get their information. They figure out what they need to know. They forget where they need to go get it, and then they go get the answer and they put all that together. Then after that, in this section here, they go and they get into a big room, and they start putting together the story. It’s the Pepe Sylvia thing from It’s Always Sunny in Philadelphia, where you’re putting red yarn everywhere. The ultimate output of this is kind of like an ugly first draft. Everyone’s put together their stuff. You discarded things that are less important, and now you’ve got a first draft.
Now, what is this section about the query key values? How does that impact our usage of AI? You can see how computationally expensive this is. If every writer has to talk to every other writer, and everybody’s got to have all their Post-it notes on one board, that’s a big old board, for one thing, right? It means that if we have irrelevant stuff, if you got, you know, Bob is over there getting drunk at the local saloon, he’s going to bring back a bunch of garbage. That’s not going to help us put together a good story. So even though we say more data is better when you’re using generative AI in your prompts, it has to be relevant data. You don’t want to just toss everything in. You want to toss in things that will advance the story, the relevant, specific information. Jargon is really helpful because that’s like giving a writer a very focused piece of story to go hunt down.
So that’s a good place to stop for part two. In part three, we’re going to talk about the editor’s room, and then ultimately sort of typesetting in part four, and then part five will wrap up with what does this all mean. So stay tuned for the next part.

Mind Readings: How Generative AI Models Work Inside, Part 1
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
This week, we’re going to get into the blood and guts of generative AI, in particular, large language models like the kinds of power, chat GPT, Anthropic’s Claude, Google Gemini, etc. Over in the Content Marketing Institute Slack, Joel Barker had asked if the short video that I had posted of how a Transformers model works could be something that has a bit of a voiceover to explain what’s happening. So first, we’re going to play through the entire video itself, so you can see what’s happening. This is by B.B. Croft. This is an illustration of what happens in a generative AI model. So, I’m just going to go through, and you can read the explanation along the side. However, the explanation is very, very technical, so let’s just watch and see what happens.
From the moment that you put a prompt inβin this case, a very simple promptβthat prompt then gets tokenized. The tokens are then vectorized and then embedded, and you create the input embeddings. Then it goes to the query key value caches to get dot products, and then this continues on down through the multilayer perceptrons, through the attention mechanism. These are the transformers that are doing their mathematics on it. Then you get to a layer norm, the logits, the logit soft max, and eventually you get the next token in the sequence. Then this happens over and over again.
Now, if you know mathematics, you know lineal algebra and calculus and stuff, it’s pretty clear what’s going on here. If you don’t know those things, it’s not at all clear what’s going on here. So what we want to do is take this apart as a series of what’s going on inside a model, and we’re going to do this probably in multiple parts because the explanation is going to get lengthy. More importantly, what do we learn from it? What does it teach us about how to use AI better? Because it’s cool to understand the architecture. It’s more useful to understand why these things matter so that we can develop better strategies for working with AI.
So let’s get started. We’re going to go back to the top of our model here, and we’re going to start with the prompt. So, when you put a prompt in, the first thing that happens in a generative AI system is the prompt is tokenized. What that means is it is transformed from letters or parts of words or words into numbers because generative AI and all AI is incapable of working with text. These are mathematical tools, statistical tools. As a result, math is the only thing they understand.
So when we type in a prompt into chat GPT, the first thing it does is it has to turn it into math. It has to turn it to numbers, and then those numbers can be processed. Let’s use an analogy. We’ll use the analogy of a newspaper, a very peculiar newspaper. There’s an editor in chief, there’s a writer’s room, and there’s an editor’s room. Ultimately, there’s sort of a typesetting room, and what comes out at the end of the day is the newspaper, right? So that’s going to be our analogical framework for this series.
The prompt is kind of like the editor-in-chief bursting into the writer’s room and says, βHey, everybody, we got a new assignment, and it’s a big one.β So, we’re going to break up this assignment into little pieces. The editor takes the pieces of the assignment, hands it out to all the writers, and every writer’s got, like, three words to work with on this story. That’s the first step. That’s that tokenization step, where you take the assignment and you break it up into little pieces.
Then what happens is in the next step, right, the embeddings. So the assignment’s been broken up in little pieces. Every writer has to look at the words, or the pieces of words. Maybe they got, like, two words on a sticky. They have to figure out, βHow does this relate to other words that I know about?β That’s the token embedding. Then they also have to say, βHow does this word relate to other words that we’ve been given in this assignment, in the order in which they appear?β
Because language is not really random, right? You don’t say, βI pledge leads to the flag backwards.β That makes no sense. The sentences make sense. There’s a logical flow of words. Those rules we call grammar. When a model is taking apart our prompt, it’s like all those writers taking apart the assignment but remembering in what order the pieces of the assignment were given, right? If the editor comes in and says, βWe’re doing a story on corruption at the docks down in Long Beach, and I need someone to go down and investigate the dockmaster. I need somebody to go to a shipping yard. I need someone to go to container yard,β the sequence of things that the editor-in-chief is giving orders to, we’ve got to remember that, because maybe the sequence matters.
In this fictional case, what if talking to the dockmaster is not a good idea because you need to talk to the shipping receivers first for this fictional story that we’re working on? So that’s the first step: the assignment comes in, gets broken up into pieces, and then assigned to writers. The writers have to figure out what their little piece of the story is, what they know about it, and how it relates to the other pieces.
Those two things are sort of multiplied together inside the model to create what’s called an input embedding, which is almost like a master project plan, if you will, of who’s doing what, in what order, and then it proceeds on. So we’re going to stop there, because this already is a lot.
What do we take from this portion? Just from here, just from this portion, we see that what goes in our prompt has to implicitly have things like knowledge, right? The more relevant knowledge we provide, the more of those writers know what the assignment even is. More detail. A good creative brief has more detail. The order in which the words appear matters. So if we are providing structure and order in our prompts, there’s a good chance that will help improve the performance.
So that’s going to be the end of part one. In part two, we’re going to dig on further as to what happens next in the writer’s room, which is going to be really, really messy. So stay tuned for that.

What’s On My Mind: The Future of Work in an AI World
This week, let’s talk a bit about the future, inspired by several things. First, my friend and colleague Constantine von Hoffman asked what I thought the next 6-12 months look like for AI.
Spoiler: no idea. But we’ll come back to this question in a bit.
Third, this week I started using aider and cline in my software development work, and am properly blown away by both and what they enable.
So, let’s talk about the future.
Caveat lector: the future, by definition, is not set. With the world as unpredictable as it is, by the time I press send on this newsletter, it could very well all be wrong.
Part 1: The Future of Work
We’ll start with the World Economic Forum report. Screenshots and tidbits of it have been floating around on LinkedIn, but let’s dig really into the meat of it. With documents like this, I strongly suggest loading it into a tool like NotebookLM and then asking questions of it. You’ll get credible answers drawn from the document itself.
Here are a few of the specifics:
“Technology is predicted to be the most divergent driver of labour-market change, with broadening digital access expected to both create and displace more jobs than any other macrotrend (19 million and 9 million, respectively). Meanwhile, trends in AI and information processing technology are expected to create 11 million jobs, while simultaneously displacing 9 million others, more than any other technology trend. Robotics and autonomous systems are expected to be the largest net job displacer, with a net decline of 5 million jobs.”
Also from the report:
Today, 47% of tasks are human only
30% are human/machine hybrid
22% are machine only
By 2030, according to their survey:
– 33% of tasks will be human only, a 29.8% decline
– 33% will be human/machine hybrid, a 10% increase
– 34% will be machine only, a 54% increase
And who’s exposed to the greatest risks, in terms of machine substitution by generative AI?
Skills involving reading, writing, and mathematics
Marketing and media
Systems thinking
Multilingualism
Programming
(plus AI itself, as agentic AI consumes more of AI overall)
That wasn’t the only paper that caught my eye over the last couple of weeks. The National University of Singapore published a study on how AI is impacting the freelance market.
The short version of that paper is that when AI isn’t fluent and skilled in a domain, freelancers using AI see big boosts in earnings, up to 65%. Once AI becomes fluent and skillful in a domain – like language translation – freelancer earnings fall by 30%.
Back to the WEF report, one of the whoppers in it was this:
“On average, workers can expect that two-fifths (39%) of their existing skill sets will be transformed or become outdated over the 2025-2030 period. Extrapolating from the predictions shared by Future of Jobs Survey respondents, on current trends over the 2025 to 2030 period job creation and destruction due to structural labour-market transformation will amount to 22% of todayβs total jobs.”
Now, let’s talk about this a bit. I’m decidedly pessimistic about the report’s conclusion that we’ll see a 7% net increase in jobs. Why? Because in a free market civilization where net profit is the tangible, measurable goal of most corporations and for-profit entities, the goal is to increase profits while reducing costs.
I do think the estimates for how much work AI will consume ring true; both NUS and the WEF report estimate that AI will consume about 30% of work, which makes sense. But I don’t think labor numbers are right, for one simple reason: tasks are unevenly distributed.
Let’s take the average marketing agency. Companies are inherently pyramid shaped for the most part. There’s very few people at the top, and a whole lot of people at the bottom. At the bottom you have roles like analyst, coordinator, specialist, and other related titles, the junior staff. These folks do the grunt work for the most part.
Preparing and scheduling meetings, assembling reports, taking notes, collecting data, writing first drafts of marketing documents…
You can tell by just that short list of very common tasks that those are all tasks today’s AI tools can do fluently. Meeting note-taking is so automated now that entire companies will deliver AI summaries, to do lists, takeaways, and transcripts of pretty much any meeting audio. Google just rolled this out natively in Google Workspace.
What happens when the bottom level of the pyramid can be done by machine? The next level up – the account managers, account supervisors, account executives become the operators of the machines that are handling the lowest level tasks. And over time, as AI becomes more fluent in more tasks, the number of people you need at each level diminishes.
We used to say, “AI won’t take your job. Someone skilled with AI will.” That’s somewhat true, but not entirely. There are plenty of jobs, especially at the lowest levels of an organization, where all the tasks that comprise that job can be consumed by AI.
But you might say, “Chris, someone still has to operate AI! We can’t get rid of everyone.” No, we can’t. That’s impractical, and as a number of companies found out recently, firing everyone and hoping AI can do everything is not a winning strategy.
Not recently, anyway.
But that’s going to be less and less true over time. Which brings me to part 2.
Part 2: The Future of Tasks
I’ve been creating software with generative AI for well over a year now, ever since GPT-4 conclusively proved it could write at least moderately fluent code. Most of the time, it would write code that was 90% of the way there, but as software developers know, code that is 90% working is code that is 0% working, because code has to be syntactically correct to run. Computer languages are unforgiving; misplace a semi-colon and your entire app might not run.
But that was then. Over the past week, I’ve been playing around with two different AI coders – aider and cline. Both are free and open source, though both require you to provide them access to an AI model of some kind, like Claude, GPT-4o, Deepseek V3, Gemini, Qwen Coder, and other models. I’ve been using Deepseek V3 because it’s comparable to other state of the art models at ridiculously low cost.
When you use a tool like cline or aider, you don’t write the code. You give instructions, prompts, and it writes the code. But it does so within an environment where… it just runs. It’s an example of what the future of AI looks like, tools that run semi-autonomously or even autonomously.
I have a short 1-minute video that’s a time lapse of Cline and Deepseek building an MVP – minimum viable product – inside VSCodium, a coding tool. As you watch it, you see it writing, then editing, then proofreading its code with me only occasionally pushing buttons or giving clarifying instructions.
Tools like Replit do this entirely autonomously now. No human needs to babysit them. You give them the instructions, and they figure it out. It may take a bunch of tries, but it gets there eventually.
How eventually, and how much does it cost? The setup I was using cost me 25 minutes of babysitting time and a whopping 6 cents of compute costs using Deepseek V3.
Now give that some thought. A high value task like building an app – granted, a very simple one – would in the past have taken hours, perhaps days, of a developer’s time at $100 an hour minimum for on-shore developers. Offshore developers cost less, but still cost a good amount of money.
AI accomplished the same task in less time than a lunch break and for less than the tip you’d pay on a soft drink order at a restaurant.
When you watch it code and debug, you’re struck with just how capable these tools are. I provided the idea. I provided the requirements. I provided clarifying answers to questions it had.
That’s it. It provided the skills.
There’s a reason hiring demand for software developers has been near pandemic-level lows for the last year with no sign of recovery, at least according to data from Indeed.com. The job of a software developer isn’t putting fingers on keyboards much any more. The job is now ideating and providing high level guidance – being the expert during pair programming, while AI is the junior programmer.
Can you imagine that same kind of work being done by AI in, say, a corporate strategy document? Going back and forth, making edits and refinements, asking clarifying questions, but doing all the labor itself?
This is why I’m pessimistic about the World Economic Forum’s report in terms of jobs created. I think they’re wildly overstating the number of jobs AI will create. Yes, we will need more expert engineers to solve very difficult problems, but the pathways to becoming one of those expert engineers will be smaller and narrower as AI does more.
It’s also worth reminding that I am not a software developer by training or trade. It’s not a core skill set of mine. I’m a technical person, yes, but not a hardcore developer. So what you see in the demo is a person with an idea and good vocabulary to know what to ask for, but not a coder, doing the job of a junior coder.
In certain circumstances, AI absolutely will take your job. And the list and scope of those circumstances is going to increase over time. Today, for the average user, there is no need to use a human translator to translate one language to another. Generative AI is so fluent and capable at it that it will get the job done for anything that isn’t critical. (critical meaning a faux pas would start a war or something) That profession is experiencing less demand and will need fewer people.
Software development as a profession is going to change radically. Marketing is going to change radically.
How soon?
That brings me to part 3.
Part 3: The Future Is Already Here
Constantine von Hoffman’s question about what the next 6-12 months holds for AI is, frankly, a giant question mark. There’s no way to know. We do know that huge models like Llama 4 are roughly midway through their training now, and probably will be released in the coming months. We know OpenAI is beginning testing on o3, their advanced reasoning model.
We know, thanks to agentic frameworks and reasoning models that prompt engineering is changing radically. The gap between someone incompetent with AI – “write me a blog post about marketing!” and highly skilled at AI is closing, fast, thanks in part due to reasoning models that automatically try to infer what your intentions are.
And we know there are significant architecture changes on the horizon as all the infrastructure around AI models changes and matures, from Google’s proposed Titan architecture to agentic RAG (document and knowledge retrieval, handled by AI autonomously).
The most mind-blowing technical capabilities of generative AI exist today, right now. They have, by and large, not been put to use yet. That’s what the next 6-12 months really holds – taking the capabilties we have today, and turning them into practical use cases.
A not so simple use case? Imagine adding a world-class trial lawyer to your bench when it’s your day in court. Your human lawyer is sitting with you there, and Gemini is listening, watching, and providing realtime feedback to your lawyer about what it’s seeing, what it’s thinking, and with Gemini’s grounding in search, even providing suggested strategies and tactics.
Imagine that same capability at your next quarterly board meeting. You sit at the table with the rest of the C-Suite as everyone delivers their updates and plans for the year. Gemini, primed and loaded with the world’s best corporate strategy knowledge, acts like a consultant. It listens to everything and provides you real-time feedback like suggestions, approaches, and cautions.
Imagine you’re at the doctor’s office. You’ve pre-loaded a secured Gemini instance with your existing healthcare data, and as your doctor reviews your records, Gemini does the same. It prompts you and the doctor to consider other possibilities – maybe that weird tingling sensation in your foot isn’t your imagination after all, and then a rank-ordered list of questions for you and your doctor to explore.
These scenarios may seem futuristic, but the technology to implement them is in market today. It’s not theoretical. It’s not sci-fi. It’s available to you right now, here, today.
Our job is to build it, to harness those powers.
In the next 6-12 months, the arms race among the big vendors will rage on, but for the rest of us, the race to use AI to create value is where the action really is.
Part 4: Your Next Steps to the Future
So all this is great. What do we do with it? What are the practical takeaways?
If you’re concerned about job loss, the time to learn AI is now. No matter what you’re currently doing with it, you could be doing more. I could be doing more. There’s so much possibility. So the first place you start is with a task and skills audit – for yourself, for your team, for your company. Shameless plug, my company, Trust Insights, does this. My business partner Katie is the absolute best at helping organizations understand their capabilities and deficits.
Second, once you’ve done your audit and you know where your weak spots are, you practice. You roll up your sleeves, dust off your keyboard, and sit down with the AI model of your choice to see how you could use AI to implement tasks within your weak areas and blind spots. Maybe you’re comfortable doing writing with generative AI, but not doing strategy and planning. Maybe you’re comfortable writing ad copy but not creating code. Whatever the blind spots are, use AI to mitigate them.
Third, you focus on the three MOST BESTS that I talk about in my keynotes. Whoever has the most best ideas, data, and brand will win in the AI era. You need to build your ideation muscles to figure out what’s possible and what’s profitable in your industry that AI can build for you.
You need to find all your data, public and private, put it into formats AI can recognize, and then start extracting real value from that data.
And finally, you need a strong brand, because in the era when we don’t need to ask search engines or social media for answers, the only way you’ll ever get recommended is if AI knows who you are. That comes from having a big, bold brand that shows up in training data and then in AI models.
If you do this, if you follow this process, you’ll be better positioned than 99% of your peers who have no idea what’s coming for them. The prospects for AI-resistant people are very, very dim. The prospects for AI-forward people are very, very bright. As a technology, it amplifies what’s already there. To paraphrase from the Captain America movie, it takes the good and makes it better, and it takes the bad and makes it worse.
If you’re good at what you do, it will make you better.

Welcome back. This is where the rubber meets the road. We are at part four in our series on how to use generative AI to generate software. This is the AI use case walkthrough. In part one, we defined the requirements. I’ll go ahead and bring up my screen here. We did the requirements in part one. Let’s see if I can, it looks like it’s having issues here. Hang on for just a second, and there we go. So we worked on our requirements, this long, long list of functional and domain requirements for our software package, of all the things that it should do.
We’re making a game, a Wordle-style game. In part two, we worked out the best practices guide to tell the generative AI model how to be a good coder, to write the software, and you can see this is an extensive amount of information. In part three, we built the map of all the files that we were going to need AI to write code for. Now, I want to say this because I think this is important. At any point in this journey so far, you could stop and say, now I want to hand this off to an expert.
You could say after part one, after the requirements are done, you know what, this looks like a lot more work than I was expecting it to be. Hey, developer that I found on Upwork or Fiverr or wherever it is, you go to get developers, maybe it’s my friend’s at Global Source where I do some advising as a board member, hey, developer, here’s the requirements, here’s what we want to build. Can you build this? At the end of part two, you might say, hey, here’s the best practices guide that we think you should be using.
At the end of part three, you can say, here’s the architecture that we think this app should be at, and at any point along this journey, if you don’t want a code, or in this case, copy-paste code, you don’t have to. You can let someone else take over. I’m going through this process, A, because I just wanted to build this app, but B, to illustrate that, generative AI is very capable of doing this entire process, soup to nuts. That does not mean you have to do it. It just means that it can do it, but everything that you’ve seen so far are valuable things that you might want to add to your toolbox where you can say like, yeah, I would like to spec out the requirements for a tool or a service.
You could even use it to evaluate existing tools and services and say, hey, what are our requirements for a good SEO tool or for a good social media monitoring tool and follow the exact same process? So all of this is decomposable. You could take portions of it and use it in other contexts, and again, at any point, you can say, you know what, this is getting overwhelming, I want to stop, I want to have an expert takeover. I am going to live dangerously and not do that. Instead, I’m going to say, let’s get started.
So what I’m going to do, I’ve already taken the map and I’ve turned into all the necessary files. These are all empty files. There is not a single thing in this. There’s nothing in here. I’m going to bring up my VS Codium coding environment, and I got my list of empty files, and now one by one, we’re going to have generative AI write the code. So I’m going to start with saying, great, let’s get started writing the code to ensure completeness and adherence to the best practices and requirements, where should we start, and again, I’m asking it its advice, but where should I start?
Start with the server side, puzzle data handling endpoint. Why start here? It’s the data foundation, specific steps in order, server utilities, JS for a new server puzzles, JS. Okay, so I think this is that, I think that’s a great place to start. I am going to give it some additional directions, and the directions I’m going to give it is from my coding. What I’m going to say is, here’s a critically important instruction. As we improve code, always produce the complete code.
I say, we have no developers. We don’t have anybody who can work on this. It’s just me copying and pasting things, and so I’m giving it these instructions to say, I need you to do this this way. So with that, let’s go ahead and it says, start with the server. I’m going to go back into my project map, let’s expand out the window, and it says, start with server utilities. All right, great. Let’s start by having you produce server utils.js.
Now, again, we don’t want to have it just spit out the code. That is, generally speaking, that’s not how you want to have AI write code. You want to have it follow the same chain of thought that we did for building the requirements, for building the project map. Here is how to approach this task. First, state the functionality of the file and the requirements for it. Tell me what’s in it. Second, talk through how you will implement the functionality.
Third, explain your choices out loud of why you chose the implementation that you did in the second step. Fourth, produce the code in full. Always add a comment at the beginning and the end of the code with the files full path in the project. Let’s see, adhering to best practices and the requirements. So all we’re doing here, chain of thought, we’re giving it a manual chain of thought process. So we’re not saying, hey, just make the code. Let’s see what happens. We’re saying, no, no, tell me your plan.
What’s your plan? What are you going to do? How are you going to do this, and it’s going to say we’re going to create the server utilities JS file. This server will contain server-side function, utility functions. Its primary responsibility is to handle the logic related to puzzles, loading puzzles, and so on and so forth. Second, we’re going to use the FS system, the JSON, parse, so on and so forth. Why do I choose these things? Fourth, here’s the code. This is how you get great results out of AI.
Not by just saying make the thing, because that’s very naive, but tell me how you’re going to make the thing. I said in the previous episode, we were essentially kind of reusing an old saw from public speaking. In public speaking, there’s this old expression, tell them what you’re going to tell them, tell them, and then tell them what you told them, and that’s a fairly naive public speaking framework. There are better frameworks, Thames and Webster’s Red Thread is a great framework for that. However, for AI, that’s a great framework.
Tell me what you’re going to do. Tell me as though you did it. Tell me what you did and why and then do the thing, and that’s exactly what that process does. So here we have the server utilities. JS. I’m going to go to my disk and I’m going to open up server utilities. JS. I’m going to make sure that it will actually want all, all JS files to open VS Codium, and now I paste, and that’s it. So we’re going to do a little time-lapse here of me doing this because no one wants to watch this.
So let’s start the show. Okay, after quite some time of copy-pasting, which is all we’re doing here, copy-pasting, we have a completed folder of all of the code. So here’s all the code, and we can see, I, other than the favicon, there’s nothing here that’s zero bytes. So this is the first draft of the code. It is by no means done. I can already tell there are things missing from here. However, what we want to do is we want to have this thing evaluate what’s missing and sort of patch the holes.
So what we’re going to do is we’re going to have it do exactly that. I’m going to have it remember the requirements. So what I’m going to copy paste is this in here. I’m going to say, next, let’s review the requirements, and I’ll paste in our requirements, and then at the end of this, we’re going to give it some instructions, and the instructions we’re going to tell it are that we’re going to be evaluating this code to see if the code will actually work. I’m going to say our goal is to reach MVP, minimum viable product.
You’re going to evaluate in three steps, what it does well, what it does poorly, and what things, if any, are blocking MVP status. After you perform these steps, you’ll then integrate the changes. So our next step is to load in our code base, which I’m, what I did is I have a little utility that just takes all the text files in a directory and sews them together into one big file. We have the code base is not, this is not large. This is about, what, 4,000 words.
I don’t know how many lines of code it is, but it’s not many. So let’s see what it comes up with. Yep, several features are either incomplete or just placeholders, leaderboard logic, user authentication, database interaction, hints logic, game statistics, no input validation, styling, missing puzzle data. I knew there that piece was missing. What are the priorities, and here is a list of the priorities and how to fix them, high, medium, and low priority. So the next step to fix this is we would want to, we don’t want to have it try and fix each individual issue because many of these issues will span across files.
We’re going to borrow a page from Agile, and we’re going to say, we’re going to do vertical slicing instead. So using the MVP blockers, tell me what files are affected, and so it’s going to now review our MVP blockers and tell me exactly which files are problematic here. So high priority, here’s the server file, and here’s all the things that are missing in it for utilities or API and so on and so forth. So it’s going to spit out a long list of this stuff. What we’re going to do next is for repairing, we’re going to fix these things one step at a time, but first, we need the complete list of everything that’s wrong.
Okay, let’s go ahead and copy this. I’m going to copy this into our document here, and I’m going to say we’re going to, let’s start repairs. So let’s get repairs and upgrades underway. Let’s start with, I’m going to put a delimiter there and just going to chop out that first issue. Boom, that’s our, our first MVP blocker. Now we’re going to remind it, we’re going to remind it that we don’t have coders, so let’s not, we’re going to reuse that prompt, and we’re going to reuse a similar prompt as what we used to build the code which is, hey, tell me what you’re going to do, tell me how you’re going to do it, and then make sure you didn’t delete anything because one of the things that generative AI does when you’re asking it to code is it’ll fix something, and it’ll break something else, which is really stupid, but that’s the nature of the way the language models work.
So instead, you say, tell me what’s already in that file so that we don’t break anything. You’re going to now fix these issues. It’ll write the code, and then we force it to check it against original checklist. Did you, did you lose anything along the way? There we see now in the validation side. We remove the JSON-related code, migrate the get puzzle to use SQL Lite. Next available puzzle logic. No omitted code. Good. Update the get used for a ready. So now we can go back to our data file and patch that in.
So if you look, we went from that 65 lines of code for these utilities to about 95 lines of code. So we know that it identified a good number of things that were just not right. We’re going to move on to number two, and I’m going to, we’ll start the time lapse to go through this list because this is just a lot of copying and pasting, and no one needs to watch that for in real time. Okay, after extensive repairs, we’re ready to repeat this process. So remember, this is something that you want to do iteratively, want to have it review the code base and, and try to get us to MVP.
So the exact same things that we just did in what you can do in, in AI Studio that you can’t do in other forms of, um, AI, which is really nice is you can have it, uh, you can have it, you can remove stuff from the chat. So if I were to go through and delete all of the pieces that we’ve just done because they’re, they’re now incorporated, I could then reuse that earlier prompt. So I’m going to go ahead and delete all the older repairs that we’ve done, and you can see the token count on the window decreasing as we remove these pieces because this isn’t relevant anymore, right?
We’ve made the changes to the code. So let’s chop out all the old stuff, and now I’m going to remove the old tree and the old code. Right, there’s our requirements. Now we add in the new version of all this. Let’s make sure we have it up to date. Drop it in, and just to reinforce what we want to do, I’m going to copy and paste the prompt again. Okay, we’ve got our issues, and now, as before, we would specify our vertical slicing to have it tell us what files need to be patched and the changes need to make them.
Obviously, we’re not going to spend time watching this process. Again, you go through iterations of this, continuing to find and debug and clean. Now, at this point, once you’ve done this process and you’ve removed the MVP blockers, you’ve resolved it, you are essentially have an app that is ready to deploy. So in the last part, we’re going to talk about how to, how you bring this into production, how you, how you make this go long live, and what you might want to do with that.
But this is how you use generative AI to make software. There’s a few little odd things here and there that are unique to how I do stuff, and I should, I should be very clear. I am not a good coder. I am not a coder professionally full-time. I’m a data scientist. I’m an AI person. I am not a hardcore coder. So if you are a coder and you’re watching this and going, oh, no, that’s a, how you do it. Yeah, it’s probably not how you do it.
We tried as best as we could to accommodate that in part two, building the knowledge base about what best practices are for this kind of coding, with the understanding that, yeah, this is, this is how a non-technical person would use generative AI to create software.
