Welcome back to Part 3 of Deepseek Week on the blog here and on the channel. Today, let’s address some relevant, important questions. The number one question is, is DeepSeek safe? Is it safe to use? The answer to that question depends on how you define safe. If you were to go into DeepSeek’s website and look at things like the privacy policy, you would find very quickly that the privacy policy is extremely permissive. So let’s go ahead and go into their privacy policy. Again, this is in public. What do they collect? We collect user input. Like we may collect your text or audio input, prompt, uploaded files, feedback, chat history, etc., other things you provide. And then what do we do with it? How we use your information. Among other things, we use it to review and improve and develop the service, including monitoring, interactions. And just across your devices, analysts, how people using it, and training or improving our technology.

So if you are using the web-based version of deep seek, you are giving your data to the company to use for training. I mean, it’s pretty clear in the privacy policy. There’s, it is exactly as they say it is. Therefore, we should know that you should not be putting sensitive information to it. So no person I didn’t know if I can. Information, nothing confidential should go in there. It is perfectly fine to use for anything that is not confidential. So if you want to say, like, I want to make a new video game or I want to summarize the headlines in the news today. Anything non-confidential, totally safe to use anything confidential. I would not use the web versions. However, as we talked about in the previous version, there are multiple versions of deep seek, including versions that you can run on your own hardware. Anything you run on your own hardware is as secure as that hardware is.

So if it’s already in a protected environment, like your company behind your firewall, etc., then it will run just fine on that hardware and it will be completely private. It’ll be completely protected. One of the misconceptions, oh, there’s so many to deal with, you are seeing a lot of FUD, fear, uncertainty, and doubt being spread by Western technology companies, the tech pros about deepseek because they’re losing their shit about it. The fact that this company in China was able to beat the pants off of their models at a fraction of the cost has made all of the labs run back and say, okay, well, we need to change our approach because this company is just beating our pants off.

And then the communications teams at those companies are trying to do as much as they can to spread fear and doubt about using the deep seat. Models because they don’t want people, A, even to know it exists and B, to believe it’s profoundly unsafe because the cost is so low. It’s one one hundredth of the cost of Western models. If you are open AI and you’re trying to figure how to become profitable and a competitor says, I can do that for 99% less. You’re in a lot of trouble. So as you evaluate safety claims, be aware of the sources those claims are coming from and the conflicts of interest in them. Deepseek has given away its models. So you can take V3 or R1 and run it on your own infrastructure. The nature of generative AI models is this. The model is kind of like the engine of the car.

When you go to a web interface, the web interface is kind of like the car as a whole. So if I were to go to deep seek chat here, this is the, this is the whole car. It’s got the engine on the back end. It’s got the web interface. It’s got a bunch of other things. And of course, it’s going to log anything I put into this. If you take the engine out of the car, the engine no longer has access to the radio. I think just can take that analogy. If you take the engine out of the car, no longer has access to the radio. A.I model is nothing more than a database of statistics. If you want to learn more about that, you can take the paid mastering prompt engineering course from Trust Insights, but a model is just a database of statistics.

It cannot record its own data. It cannot call home. It cannot do any of those things. It is just a database. You install it and run it on your hardware. You put it in a car that you own and then it can’t call home. It has no ability to do that. So to answer the question, is deep seek safe to use? If you are running it on your infrastructure, it is a 100% safe to use. You saw in the previous video, I was running that distilled version of Lama on my computer and it was completely private to me. If you have the money to run V3 and R1 on your infrastructure, completely private to you, totally safe. If you are using their web interface, unsafe for private information. So do not put private information in there.

One other thing is important to talk about when it comes to privacy of information is when someone uses your data to train a model, what that means is that your data is stored in there somewhere in their training data set. So a human being could get access to that perhaps, depending on the company. When it goes into the actual model itself, it’s not going in verbatim. What happens is your training data, your data gets turned into statistics and it gets poured into the bucket with all the other statistics. Imagine you had a cup full of sand. There was like, bright red sand. And you go out to the Sahara Desert. And that represents all the other train data. And you take that cup of red sand, just dump it in the desert. Could you then take that cup, scoop up the sand from the desert floor and have some of your red grains in it? Yes. Could you reconstruct the order of those grains? No. Could you guarantee it was your cup was filled only with red sand? No. That’s kind of what happens when your data is used to train someone else’s model. It can get pieces of it can get incorporated. Yes. And pieces of it can be retrieved, yes, but not in any sense of order.

So that’s part one. Part two of answering the question about is it safe is bias? Are deep seek’s models biased? Yeah, but so are all models. They’re all trained on human data. They’re inherently biased. Western models like Gemini and Chat, GPT, and Lama have different biases. They will not answer some questions. Deep Seek will not answer some questions. You ask it about Tiananmen Square or ask it to be critical of the Chinese government. It won’t. It can’t do that. It won’t allow you to do that. However, if you do, if you ask sensitive questions to Western models, they will also provide you tons of refusals. You can’t do anything with politics in Gemini. Gemini will just outright refuse and say, nope, can’t do that. It won’t help you with that.

You can’t go into any image generator and say, please make a rendering of the weapons bay of an F-35, even though that is. Information is available online and the models have probably trained on it, they are censored as well. They will not allow you to do that. All of the Western image models, the services will not allow you to construct certain types of images, images containing nudity or a gory violence. They won’t let you do it. So is deep seek, censored? Yes. Is the model you’re using today censored? Also yes. What I have found in my testing is that it is actually less censored in many things than the Western models. It will let you talk about politics with no trouble. It will let you ask questions, as long as it’s not questions directly about being critical of the government of China, you can ask it pretty much anything you want.

You can have it do all sorts of things that Western models will not allow you to do. So in that regard, I actually think it’s safer, it’s more permissive of different use cases than many Western models. So to wrap up, is it safe? Depends on in context. If you’re dealing with private information, don’t use the web interface. If you are dealing with private information, download it and run it on your own hardware. If you can support it, if you can’t support it, then use a model that you can’t afford and support if you can’t afford the infrastructure for it. For things that are not private, it is 100% safe to use. I would encourage you to use it because it’s pretty incredible. The results it gives are at or nears a state of the art. And from a pricing perspective, dirt cheap. So definitely use it for that.

Machine-Generated Transcript

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 a—let’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.

Machine-Generated Transcript

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 safe—all 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 company—a Chinese technology company—that, 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 up—I 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 score—the average quality score to choose on most benchmarks—is 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 cents—no, 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 things—these two models—are 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 training—the chefs there—in 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 to—how 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 more—I guess you would call it—intuitive 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.

Machine-Generated Transcript

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, “Okay, we got to figure out who’s doing what and in what order.” 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 provide—and the editor-in-chief is us in this analogy—the 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, “Okay, well, maybe I’ve got bad data or wrong data or irrelevant data. Maybe I’ve got conflicting instructions in my prompts.” You might say, “Be verbose,” in one section, and another section, “Be concise,” 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.

Machine-Generated Transcript

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 work—the bloody guts, the highly technical deep dive into these things—inspired 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, “Like, this is relevant, this is relevant, this is okay.” Then they end up with a refined version of the story. The editor-in-chief takes a look so far and goes, “I love this, I love this is, I love this is going, but I need more.” 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, “Hey, let’s write an article today, folks,” all the reporters are going to be like, “Uh, what should we do?” and the writers are like, “I have no idea.” Everyone comes up with random stuff, and that goes to the big whiteboard, and the editor is like, “Uh, I guess we’re going to try and write a story about something.” What comes out is bad. If the editor-in-chief says, “We 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,” 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.

Machine-Generated Transcript

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, “Boy, 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.” 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, “Well, 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.” They go through this process of refining the story over and over again. The activation layer here is the editor saying, “Let’s change synonyms, improve the flow. Let’s move things around. Let’s continue edit.” 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, “More. I want more of this.” 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, “Here’s what I want you to do. Here’s how to do it. Here’s your style guide.” If we’re writing, if we’re doing creative writing as a prompt, “Here’s what my writing style is.” If we’re doing strategy, you know, “Here’s the tone of voice you should use.” 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 framework—role, action, prime, prompt, evaluate, learn—because 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.

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, “Okay, now we got to work on the story.”

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 value—imagine you’re one of the writers in this writer’s room, and you get a small part of this assignment. Maybe you have to—in the previous episode, we were talking about how maybe the editor-in-chief wants an investigation of corruption at the shipping docks in Long Beach—and you are given the part of the assignment that says, “Go to Daew Industries dock and check out what’s coming in on their cargo ships.”

So the writer, you, would sit down and go, “Huh, what do I know about this?” Maybe get out some Post-it notes, and you first write down, “What do you know about Daew Industries? What do you know about shipping containers? What do you know about docks?” 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, “Okay, well, where might I find information about this?” Then the value part is where you get more Post-it notes out, and you start saying, “Well, I would know, I know where the address of the docks is. I know who runs these docks.” 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 here—the attention matrix, right, and the projection weights, the attention output—what 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, “Okay, 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.” 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, “Well, 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.”

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, “Hey, I got a story about corruption at the docks.” 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.

Machine-Generated Transcript

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 in—in this case, a very simple prompt—that 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, “Hey, everybody, we got a new assignment, and it’s a big one.” 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, “How does this relate to other words that I know about?” That’s the token embedding. Then they also have to say, “How does this word relate to other words that we’ve been given in this assignment, in the order in which they appear?”

Because language is not really random, right? You don’t say, “I pledge leads to the flag backwards.” 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, “We’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,” 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.
