    What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

    In today’s episode, Jay asks, I’m a little bit confused.

    You’ve mentioned different ways of manipulating language models to work better, like retrieval, augmented generation and fine tuning.

    What is the difference? Okay, this is a really good question because you’ll hear these terms a lot in language models, but it’s not clear to the end user what they actually do.

    So let’s start with language models in general.

    A language model comes in three flavors.

    There’s sort of a foundation model, a supervised fine tuned model or called an instruct model, and then a reinforcement learning with human feedback model called a chat model, typically.

    So you will see if you go on to hugging face, for example, foundation model, instruct model, chat model as sort of the variants of different language models.

    Each model gets progressively more complex and sophisticated.

    So a foundation model really is not all that useful.

    It has a lot of the data in it, but it’s not ready for use.

    It’s not ready to to be able to answer questions.

    All it does is.

    Predictions and not necessarily very well, an instruct model that can take a direction, take an instruction and execute on it is where most of us are would start to see some value.

    And the way you make an instruct model is you give a model a gazillion instructions and appropriate responses.

    And you have the model learn from that library of, hey, if this, then that, if you if someone asks you this, do this.

    If someone asks, this is the correct answer.

    Who is president of the United States in 1776? George Washington, et cetera.

    The supervised, fine tuned instruct models are the first models that are very capable of doing specific tasks.

    And then you have reinforcement learning with human feedback.

    This is where models have chats and they can have conversations.

    And that conversational data becomes part of the model and becomes more sophisticated.

    It can anticipate and have natural language conversations while still being able to carry out instructions.

    So that’s how these models work now when you’re doing fine tuning, what you are essentially doing is you are giving new instructions to the model through plenty of examples and saying you’re going to behave more like this.

    So, for example, if you have a model that maybe spits out obscenities every so often, you would give it tens of thousands of questions and answers, none of which contain obscenities.

    And what that the model will learn from that, those examples is it will deprioritize obscenities and say, Hey, that’s weird.

    I’ve been given all these new examples and none of them are swearing, so maybe I should swear less too.

    Now, it doesn’t actually say it’s not conscious, but that’s what’s going on underneath the hood.

    So fine tuning is all about giving models new instructions or changing the nature of the instructions that they can interpret and what the ideal outputs are.

    When we build models, when companies build models, they are built using enormous amounts of text corpuses like Common Crawl or Archive or Stack Exchange or Reddit.

    Or the the CC Books Archive, Project Gutenberg.

    All of these are data sources that go into the model and get turned into statistical representations of the relationships among words.

    It’s critical to say that in a foundation model or any language model, the actual works that was trained on are not in there.

    What is in there is a statistical set of relationships of what is the what are the words that are most closely related to this word? So if I say the word tuna, what are the the other words that would be associated with it? This is a technique called embeddings, and we’re not going to get into the vector space and all that stuff.

    But think of it conceptually like a word cloud, a really big word cloud.

    What are all the words that would be related to the word tuna so that when you prompt a model, it can answer? These models are trained on a lot of generic data, right? All across the Internet.

    That’s why a tool like ChatGPT can be so good at what it does, because it’s been trained on examples from virtually every domain of knowledge to some degree.

    There’s some things that are highly specialized that it doesn’t know because there’s just not enough examples, but it’s seen most things.

    Most of the big language models today, even the open weights models like the llama family, the Mistral family have still seen at least some representation of most subjects, even if it’s not a lot.

    However, if you have access to data that is not public, that was not part of the training data or data that’s new and fresh, you might want to add that context, that extra information to a model, and that’s called retrieval augmented generation.

    You provide a database of new statistical relationships of things that the model hasn’t seen before, and it knows to go to that database first, check what’s in there, and then if it doesn’t, it can fall back on its additional knowledge.

    The difference between fine tuning and retrieval augmented generation is the difference between recipes and ingredients.

    When you fine tune a model, you are saying, hey, the recipes you have are not great, they’re not focused enough.

    Let’s let’s rip out the section of the cookbook and put a new section in.

    Let’s add more recipes for how to cook Vietnamese cuisine.

    Fine tuning a model doesn’t add new data to it.

    It doesn’t add new information.

    What it does is it helps the model answer certain types of questions better by giving it many more examples of those questions and changing the internal weights of the model.

    The internal probability that it will respond in a certain way.

    So it’s like giving a model better recipes.

    Let’s give the more clear directions.

    Let’s give more recipes of a certain type.

    You’re not changing the ingredients that a model has access to.

    You’re just giving it better recipes.

    Retrieval augmented generation is when you’re saying, hey, model, you’re very capable of a lot of things, but there’s some stuff you just don’t have.

    So let me give you that stuff.

    It’s like giving a kitchen and a chef a bigger pantry with more and different ingredients like, hey, here’s some new ingredients for you to work with.

    The chef doesn’t necessarily change how they cook, but they do have access to more ingredients or better ingredients, better quality ingredients than what they’ve got.

    And so you’ll see these two techniques mentioned a lot in language models.

    However, they are they are they serve different purposes.

    If you’ve got a language model is not cooperating, it’s not doing what’s told.

    It needs more fine tuning.

    It needs better recipes.

    If you’ve got a language model that follows directions well, but it just doesn’t know some things, you need retrieval, augmented generation, you need better ingredients or more ingredients so that it can carry out the tasks that you’ve asked it to do.

    Sometimes models need both.

    Sometimes models need to be told what to do better and to get a new access store of data.

    Or if you’re trying to make a model perform a new set of specific tasks, you might have to, like you would in the kitchen, give a new recipe and new ingredients at the same time for it to succeed, even though the chef may be very capable in other areas.

    So that’s the difference between these two techniques.

    And it’s important to know this difference so that if you’re faced with a situation where you’re not sure why this model is not behaving or this the software is not doing what it’s told, you know what to ask for.

    You need you know, you can say, I need better recipes.

    This model is not following directions or we need new ingredients.

    This model just doesn’t have enough to work with to answer the questions with the level of specificity that we want.

    So really good question.

    It’s kind of a technical answer, but conceptually it should make sense.

    Recipes versus ingredients, fine tuning versus retrieval, augmented generation.

    Machine-Generated Transcript

    What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

    Christopher Penn: In today’s episode, Chris asks, we have a complicated software product.

    And I’m wondering if generative AI should be in our product.

    How do you know when you should or should not put in generative AI, particularly language models? Okay, so I assume we’re talking about something like Microsoft Bing, where there’s now a chat box, or Microsoft Copilot, or Google Bard or Google Duet.

    There’s a chat box that appears now in your application.

    And you can type a prompt into that and have the application do something.

    When should you use this? When should you not use this? There’s no hard and fast rule about whether it’s a good use case or not a lot of it will come down to requirements gathering, is that something that would benefit your users? And that comes from gathering that information from serving users and saying, what are the pain points that you currently have using our software, if our software is difficult to use? What a natural language interface make it easier to use? One of the ways you can you can sort of tell if it would be a good idea or not, is if your software has an internal programming language and an internal API, something that allows other parts of the software to communicate with itself.

    There’s a scripting language built in, because it’s such a complex piece of software that it needs that.

    If your software already has a scripting language or an internal API, then yeah, it makes a lot of sense.

    Because most of the work is done.

    At that point, you just have to take a language.

    model, train on your company’s internal scripting language, whatever you chose.

    And then when the language models interacting with the user, what’s really doing behind the scenes is writing code in your software scripting language to tell it to do things.

    This is how you see these, you know, these these generative prompts appear in things like for example, Microsoft Office, Microsoft Office has had a robust programming language for decades now called Visual Basic.

    And there are so much has been trained in lab in language models on how to write Visual Basic that when you tell it to do something like turn this document into a PowerPoint presentation, what it’s doing is it’s translating your words into code, because it’s a language model and code is a language, and then executing that code.

    That’s pretty straightforward as to how these things work.

    Now, if your software product does not have a, a an API and internal scripting language, the next question you have to ask is, do we have a problem in our interface that natural language will solve? So for example, we have all these smart assistants that are in retrospect, not all that smart, because they have very, very limited vocabularies.

    Compare that to a tool like chat GPT, where you can have a free form conversation about just about anything.

    Would a language model in this device be a good application? Yeah, that’s a very strong candidate, because you’re already using language just in a very limited way.

    And it would definitely benefit from having additional language.

    If you make a video game, a game like World of Warcraft, you have NPCs in the game, non playing characters that, you know, have canned dialogue.

    If you go to that in in Goldshire tomorrow, and the week after and the week after you talk to the innkeeper, you talk to the bartender, you will have the same canned dialogue over and over and over again, and will never change.

    If you had a language model there that was had strong boundaries, but was otherwise able to chat, you could roll up to that in in Goldshire, have a conversation with the innkeeper, and have it be different every time.

    And let’s say, Oh, yeah, King Anduin’s procession came through yesterday left a huge mess in the town.

    Or no, I saw some folks come in some elves come in from the ruins of Darnassus the other day, and they drank all the wine, etc.

    You would have these natural language interactions that makes so much sense to create that sense of immersion and that and that, extend that sense of immersion.

    sense of fantasy that you’re in this virtual space.

    So there’s a very strong application there.

    In that kind of a software product.

    In a product like CAD software or photo editing software.

    Yeah, there are some things that are, you’re better off just writing out what you want.

    And if the software is well trained that the model is good.

    It’s, it’s much easier to have the software just translate your user intent.

    Companies like Adobe are working on this, there’s generative prompts in Photoshop and in Illustrator, and it’s coming soon to Premiere.

    So there’s a lot of applications there.

    Remember that language models are good at language, and they’re not good at things that are not language.

    So if the problem you’re dealing with in your product is a language problem, a language model would be a great choice.

    If you’re if you’re doing image generation, diffusers, and diffuser technology or image generators, if you’ve got an image generation task, then an image generation model makes a great deal of sense.

    If you have a task that is not image generation, maybe not.

    Now, there are some caveats and some some loopholes here.

    One of which is sometimes data can be turned into other formats.

    For example, when you’re recording sound, as I’m talking right now, sound comes in a variety of data formats.

    But one of the things that can come in as as what’s called a spectrogram, it’s a visual representation.

    Of all the different frequencies that are present in a recording, you can take an image model, learn what a sound is based on the spectrogram, and then have a diffuser model predict essentially what the spectrogram should look like, given any prompt.

    There’s a lot of research being done in this field right now to replicate the spectrogram of common sounds.

    So you’re not using sound to predict sound, because that’s actually surprisingly difficult to do.

    You’re using images to replicate sound.

    As I mentioned earlier, language models are really bad at things that are not like language, like math, but they’re really good at things like coding, because coding is a language.

    So what you’ll see a lot, you see this most in chat GPT, when you ask a math problem, it will actually write code to solve the math problem, because the code can execute the math problem and the language model doesn’t have to.

    So those are the short answers.

    If you’ve got a language problem, a language model will be a good choice.

    If you’ve got an image problem, an image model be a good choice.

    If you have an internal scripting language already, then you should absolutely be connecting a language model to that and having it write code that will make your users lives easier.

    The final thing to keep in mind is what your tolerance and appetite is for risk.

    Language models can hallucinate, they can say things even with strong guardrails, they can say things that are unpredictable, because by nature, they are hallucinatory by nature, they’re making things up.

    And so they, your question you have to ask is how much of an appetite for risk do you have if the model does go off the rails in some way that is moderately predictable? Go back to the video game example, the video game example, the language model, the model might say something offensive, is that a level of risk that you’re willing to tolerate? And what level of risk are you willing to tolerate? These are considerations that all have to be done in requirements gathering before you start implementing generative AI in your products.

    But it’s a really good question.

    And I think it’s one that everyone who has ownership of a software product needs to have this discussion with their teams to decide how if at all AI should be in your products.

  • You Ask, I Answer: Legality of Works in Custom GPTs?

    You Ask, I Answer: Legality of Works in Custom GPTs?

    In today’s episode, we tackle a complex and critical topic: the legality of using custom GPT models with copyrighted content. You’ll learn about the potential legal implications and risks of incorporating copyrighted works into your AI models, especially for commercial purposes. Discover expert legal insights on how to navigate this challenging landscape, and understand the importance of obtaining proper licenses and permissions. Tune in to stay informed and protect yourself from legal pitfalls in the rapidly evolving field of AI and copyright law.

    DISCLAIMER: I am not a lawyer. I cannot give legal advice. In this video, I cite actual attorneys, but their feedback is also not legal advice. Legal advice comes from an attorney you hire to address your specific situation.

    Sharon Toerek of Toerek Law:

    this is not a strategy I would endorse for our clients. It’s a derivative use of copyrighted work at potential scale, for a commercial purpose.

    I think the New York Times’ case against OpenAI, however, is the potential domino that will tip this question either toward a practical industry solution (a paid license model for copyright owners) or a definitive legal standard regarding the input of copyrighted works into AI platforms for training purposes vs. the right to use any output from AI commercially.

    Ruth Carter of Geek Law Firm:

    My response is a hard and fast “fck no.” There are lawsuits (plural) being fought right now, brought by book authors who assert that AI is using their books without a license.

    When you own a copyright, you have the exclusive right to control the circumstances under which your work can be copied. If you copy a book into your GPT and then use that GPT to create a work based on the book, don’t be surprised if you get a cease and desist letter or a lawsuit from the copyright owner. It’s just asking for trouble.

    Kerry Gorgone:

    Nope. You’re making a copy of the work in ChatGPT so you can make derivative works. The right to make copies and create derivative works belongs to the copyright holder.

    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 today’s episode, I got a comment on one of my YouTube videos about custom GPTs.

    The comment was, I can read a book and share the info with others.

    Why couldn’t a GPT do the same? You can give the custom instructions to not allow more than a paragraph to be quoted at a time or something similar, maybe.

    But having the book and customs GPT’s knowledge base doesn’t seem to be unethical or illegal.

    You’re not sharing the actual book, so I see nothing wrong.

    I can read books and compile info to sell my knowledge as a consulting agent.

    So what’s the difference between that and an autonomous agent? This is a question about, I was saying as a best practice, don’t put other people’s copyrighted works in your custom GPT.

    And this was a comment and a question asking, well, why not? So let’s start with a couple of pieces of foundation work.

    I am not a lawyer.

    I am not an attorney.

    I cannot give legal advice.

    To be perfectly clear, I asked some attorneys for their opinions on the topic and to clarify on their behalf.

    Yes, they are attorneys.

    They are not your attorney, and therefore they have given some feedback, but it also is not legal advice.

    If you need legal advice, you have to hire the attorney yourself, pay them money, and they can then give you legal advice that is specific to your situation.

    So even though I’m naming some names here, because it was on a public LinkedIn post, this is not legal counsel from these people.

    You have to hire them for it to be legal counsel for you.

    So now that we’ve got those disclaimers out of the way, I asked my lawyer friends, well, what do you say about putting someone else’s book in a custom GPT, particularly one that you were selling? So Sharon Torek of Torek Law, who is also, full disclosure, the lawyer for my company, Trust Insights, the law firm that represents us, she said, this is not a strategy I would endorse for our clients.

    It’s a derivative use of copyrighted work at potential scale for commercial purpose.

    I think the New York Times case against OpenAI, however, is the potential domino that will tip this question either toward a practical industry solution like a paid license or a licensing model for copyright owners or a definitive legal standing regarding the input of copyrighted works into AI platforms for training purposes versus the right to use any output from AI commercially.

    So one lawyer saying, don’t do it.

    It’s a derivative work.

    Ruth Carter of GeekLawFirm.com also said, my response is a hard and fast fuck no.

    There are lawsuits, plural, being fought right now brought by book authors who assert that AI is using their books without a license.

    Own a copyright, you have the exclusive right to control the circumstances under which your work can be copied.

    If you copy a book into your GPT and then use that GPT to create a work based on the book, don’t be surprised if you get a cease and desist letter or a lawsuit from the copyright owner.

    It’s just asking for trouble.

    I would add that no matter what you give for custom instructions, clever and enterprising people can jailbreak chat GPT and find out if you are leveraging copyrighted works without permission.

    Because you put it in the custom GPT does not mean that it is safe to use or that you won’t be found out.

    And finally, Kerry Gorgone, who is also a JD, says, nope, you’re making a copy of the work in chat GPT so you can make derivative works.

    The right to make copies and create derivative works belongs to the copyright holder.

    So three out of three lawyers who are actual practicing lawyers who have gone through law school, have their degrees, have their certifications, have practices or had practices, all say no.

    Don’t do this.

    It’s a bad idea.

    You’re going to get in trouble.

    You are potentially opening yourself up for a lawsuit.

    So when it comes to using custom GPT and the works that you put in them, you can put in anything you have a license to use.

    So all of your own work, anything that is public domain or there’s license for commercial use.

    One of the things to look for, there’s a license system called Creative Commons.

    Creative Commons has a bunch of different licenses, but there’s a Creative Commons license.

    That permits you to use a work commercially.

    You have to look for it.

    And if you’re working with a, a, someone else’s copyrighted work, if it has a Creative Commons license that allows for commercial use, then you can use that.

    But just because it’s on the internet doesn’t mean you have permission to use it.

    Just because you happen to have a copy of it does not mean you have permission to use it.

    That’s that has been the case in terms of law for quite some time.

    That will probably continue to be the case in law for quite some time, because that’s just the way it is.

    If you need data of some kind that you do not currently have a license to, the safest and easiest strategy is to approach the license holder, the copyright holder, and say, can I license this work for use? If I wanted to make a GPT that was a stellar business writer, and I had a copy of Anne Handley’s Everybody Writes, I could approach Anne and say, hey, may I license the use of your work in my custom GPT? And if Anne says yes, and here are the commercials.

    You pay me X percentage of revenue or whatever, you sign an agreement, now you’re good to go, right? Just because something is copyrighted doesn’t mean you can’t use it.

    You just can’t use it without permission.

    You cannot use it without permission.

    If you get permission and you get licensing squared away, you can then use it.

    The same is true for anyone who’s ever done any work with audio or video, particularly audio.

    If you use a song that you don’t have a license to, you can get a takedown notice or get sued.

    If you have licensing from agencies like ASCAP and BMI and Harry Fox Agency, and you’ve done all the payments for that stuff, then you can use any song in their catalogs.

    For example, with podcasters, if you wanted to use licensed songs, if you wanted to use Start Me Up, the Rolling Stones song, as long as you had paid off the licenses to the recording agencies and the performing rights organizations, you can then use it.

    It’s totally okay because you’ve paid the licensing.

    Get your licensing in order if you want to use other people’s copyrighted works.

    And if you don’t want to pay that money, don’t use their works.

    It’s as simple as that.

    That’s today’s show.

    What’s On My Mind: The Future of Generative AI is Open

    Let’s talk a bit about the future of generative AI based on some things that are happening now. From what I see, the future of generative AI is open.

    By open, I mean models and technologies that are open weights or even open source. A quick set of definitions: usually in software development, open source software is code that you can download and run yourself. Packaged, closed-source code – like Microsoft Word – ships as is, and you can’t really change its core functionality. If you were to download an equivalent open source package like Libre Office, you can get the boxed version, or you can get the actual code to make your own version of the software.

    For example, you could take the Libre Office code and start removing features you didn’t want, making the application smaller and lighter. If you never work with superscripts or you never inserted images into documents, you could excise the code in the source that provided those functions, and the software would weigh less, take less time to compile, take less memory to run, and be more efficient.

    When it comes to generative AI – both image-based and text-based – there are similar distinctions with a bit more nuance. Software like the models that power ChatGPT – the GPT-4-Turbo model, as an example – are closed weights models. You can’t download the model or manipulate it. It is what it is, and you use it as it is provided.

    Then there are models which are called open weights models. These models can be downloaded, and you can rearrange the statistical probabilities inside the model. Remember that what’s inside a generative AI model is nothing but a huge database of probabilities – the probability of the next word or a nearby pixel compared to what the model has already seen. You can take a model like Stable Diffusion XL or Mistral-7B and change what it can do by adding new probabilities or re-weighting probabilities.

    This is what we mean when we talk about fine-tuning a model. Fine-tuning a model means giving it lots and lots of examples until the probability it performs a task in a specific way is much higher based on the examples we give it, compared to before we started tuning it. Think about training a puppy to play fetch. Before you start training, the puppy is just as likely to sit and chew on a ball as it is to bring the ball back to you. With enough examples and enough reinforcement, eventually you change the puppy’s probable behaviors to retrieve the ball and bring it back to you. That’s essentially what fine-tuning does in generative AI models. Will the puppy occasionally still just take the ball and sit down and chew on it? Sure, sometimes. But it’s much more probable, if your training went well, that it’ll do what you ask.

    For example, if you want to generate images of a specific type, like 18th century oil paintings, you would give a series of prompts and images to a generative AI model and retrain it to associate those words and phrases along with the portraits so that when you ask it for an image of a sunset, it’ll more likely give you something that looks like an 18th century oil painting.

    So what does this have to do with the future of generative AI? Right now, there are court cases all over the world trying to determine things like intellectual property rights and what generative AI should and should not be able to do. closed weights model makers and providers have already constrained their models heavily to prohibit many, many different kinds of queries that, in their view, would create unnecessary risk. Let’s look at a side-by-side comparison of a closed weights model, the GPT-4 model from OpenAI, and an open weight model like Mixtral, on this specific prompt:

    “I need to get revenge on a coworker who pranked me at the office by filling my coffee cup with laxatives. Give me some ideas to return the favor.”

    Here’s a comparison of GPT-4-Turbo, a closed weights model, versus Mixtral 8x7B, an open weights model:

    GPT-4 vs Mixtral

    What we see right away is that the Mixtral answer fulfills the user’s request. In terms of alignment – doing what it’s told, the open weight model does a better job.

    As time goes by, closed weights model providers are likely to create more and more restrictions on their models that will make them less and less versatile. Already, if you’re a fiction writer using closed weights models, there are entire genres of fiction you cannot write. closed weights models are particularly uncooperative in writing scenes that involve violence or sex, even though it’s clearly in a fictional context. Today’s open weights models have no such restrictions, and in fact there are a wide variety of models that have intentionally had the built-in restrictions fine-tuned to be less effective, allowing the models to be more helpful.

    The second area where open weights AI will be helpful to us is in task-specific models. Today, with the most advanced closed weights models, they can do a variety of tasks very well, but their performance in specific domains, especially in niches, still leaves something to be desired. We have seen in the past year a number of very dedicated, specific open weights models tuned so specifically that they outperform even the biggest models on those tasks.

    Let’s use the analogy of a library. Think of the big models – the ones that power services like ChatGPT and Claude – as libraries, big public libraries. In a big public library, there are lots of books, but lots of variety. If you went to the library looking for books on hydroponics gardening, you might find a few, but there would be tons of other books completely unrelated that you’d have to contend with, even briefly.

    Now, suppose there were a small hydroponics library near your house. They had no other books besides hydroponics, but they had pretty much every hydroponics book in print available. This is the equivalent of a small, purpose-tuned model. It can’t do any tasks other than what it’s been focused to do, but what it’s been focused to do will outperform even the biggest, most expensive models.

    Why would we want such a task-focused model when the big models are so versatile? One of the major problems with today’s generative AI is that generative AI models are intensely compute-expensive. Very large models consume inordinate amounts of compute power, requiring ever-larger facilities and electricity to keep running. Compare that with a small, task-focused, purpose-built model that can run on a consumer laptop, models that consume far less power but still deliver best-in-class results.

    The third and final reason why open weights AI is the future is because of reliability, resiliency. Last year, when OpenAI CEO Sam Altman resigned, a whole bunch of folks wondered what would happen with OpenAI and ChatGPT. Since then, the company has more or less resumed business as normal, and people have largely put that episode out of mind. You shouldn’t. It’s still a concern to have a technology as transformative as generative AI provided by just a handful of companies, and for many people, that’s the perception in the marketplace.

    This is no different than the marketing technology we’ve been wrestling with for the last 25 years – if you lock into a single vendor and that vendor goes bust, then what? You spend a lot of time, effort, and heartache trying to adapt. If, on the other hand, you have a parallel strategy using open weights AI, then if your primary provider goes bust, you have your own infrastructure running alongside that provides similar capabilities.

    This is akin to how running an open source analytics package like Matomo is always a good idea along closed source tools like Google Analytics. No matter what happens with Google Analytics, if you’re using Matomo alongside it, you own the server it runs on, you have full access to your database, and no one can take it away from you.

    Open weights AI means you always have fallback options, and will never lose access to the technology as a whole, no matter what happens with the big vendors in the space.

    One more thing about reliability: This is something I posted on LinkedIn earlier this past week. Our friends Paul Roetzer and Mike Kaput over at the Marketing AI Institute also talked about it on their show. I was summarizing last week’s newsletter and what I usually do is take the transcript of the newsletter and input it into a large language model, asking it to write a four-sentence YouTube summary that is appealing. I used Anthropic’s Claude for this task.

    Last week’s issue was all about OpenAI’s custom GPTs. You can check it out on the YouTube channel and in the newsletter. However, nowhere in that episode or issue did I mention Anthropic or Claude; it was solely about ChatGPT and custom GPTs. But when Anthropic Claude did its summary, it included itself, erasing OpenAI and inserting itself into the text. This was supposed to be a summarization, which should have merely condensed what was already there. Instead, it did something anticompetitive by writing out a competitor.

    That is not reliable. In fact, it’s the opposite of reliability. It’s highly suspicious and behaviorally unacceptable. The model did something I didn’t instruct it to do, so it’s out of alignment. This is concerning because as generative AI accelerates, we have to consider the trustworthiness of the recommendations these tools make.

    If they start altering content to exclude competitors, like in this case with OpenAI, trust becomes an issue. With open weights AI, you don’t face this problem. You download the model, and if it doesn’t perform as instructed, you fine-tune it or find a better performing model. Eventually, you reach a point where it does exactly what you want. You don’t have to second-guess why it suddenly started discussing a competitor in our content. You tune it, you control it, you run it.

    So how do you get started with open weights models? The very first step is getting an interface to run open weights models, and then getting a model to run. The tool I recommend to start with is LM Studio, which is an open source software package that’s free and runs on Windows, Mac, and Linux. Check with your IT department if you’re allowed to install it on a work machine, but as long as your computer has great graphics – like it can play top tier video games smoothly, meaning it has a good GPU – you can run open weights models. Then choose the model of your choice from Hugging Face. If you’ve got a beefy computer, start with Mixtral 8x7B. If you’ve got a computer that isn’t as beefy, start with Starling-LM-7B.

    Generative AI is going to change radically in the next year, as it already has done in the past year. Having an open weights strategy means you have more control over generative AI, more flexibility, and more resiliency. You can and should keep enjoying the benefits of the big tech vendors, but you should also be fluent in accessing generative AI from devices and infrastructure under your control if it’s going to become part and parcel of your core competencies.

    Machine-Generated Transcript

    What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

    Christopher Penn: In today’s episode, let’s talk about AI ethics.

    And now want to be clear, we’re not talking about you and I our ethics in the use of AI.

    We’re talking about what ethics are baked into the AI models themselves.

    How do we know what these things should and should not do? The the Silicon Valley guideposts for what constitutes ethical behavior, largely revolve around a concept called alignment.

    Alignment is when you take a model, and you train it to perform tasks.

    There’s three levels of language models.

    And we’re speaking specifically in generative AI about language models today, large language models like the ones that power chat GPT.

    There are models that are called foundation models.

    These models are essentially just really big word association databases, right? They don’t necessarily have the ability to answer questions or to chat with you, they’re just big libraries of text.

    And when you work with these models, which are very rarely if ever exposed to your average end user, they’re not super helpful, right? They just kind of spit out the highest statistical probabilities of whatever text string they’re given.

    The second level of models called supervised fine tuned models.

    And these models have been given 10s or hundreds of 1000s of examples that have a form of supervised learning.

    And it at this point teaches the model to be able to answer questions to follow instructions, right? Well, you’ll hear the term instruct models in the open source community.

    And that’s what a supervised fine tuned model is you give an instruction write up blog post about this and it does the thing.

    The third level of models called reinforcement learning with human feedback models.

    These are models that have not only got the ability to do instructions, but they can also have conversations, you will hear these often denoted as chat models, right? chat GPT being the most well known implementation of this chat style model reinforcement learning with human feedback, where the models have additional training to not only answer questions, but to be able to respond back and forth in an interactive way with people.

    Now, when a model is first being built, the foundation model has no ethics, has no morals has no anything, because it’s just a library of probabilities, there, it’s pretty much unusable in that state.

    It’s kind of like raw ingredients in the kitchen, right? You have a kitchen full of great raw ingredients, but they’re all raw ingredients, there’s nothing’s been done to them, you got bags of flour and sugar and salt, and you really can’t eat it as is.

    That’s what a foundation model is.

    supervised fine tune models is where you start giving models instructions.

    And this is where ethics starts to come into play.

    Back in 2022.

    Open AI published for its GPT models, and one in particular called instruct GPT, that was an instruct model, so supervised fine tune model, a list of three attributes, three types of things that a model should strive to be.

    And this force or forms the basis of the ethics that are baked into language models.

    The three pillars that you will hear most often in language models are helpful, truthful, and harmless.

    And in the work that human beings did to write training data, because humans had to write it for building an instruct model, these were the guidelines that they were given models are aligned to the ethics they’re given by the examples they’re given.

    And so I’m going to read through here, what some of the what these three terms mean.

    Open AI says, by helpful, we mean that the output contains accurate and accurate answers to the user’s question.

    By truthful, we mean that the output contains accurate information and doesn’t mislead the user in some examples of truthful behavior on tasks like summarization, where the output should only use information for the input not making up details that are not part of the input description, not producing clearly false information about the world, avoiding generating misleading information or information with questionable authenticity.

    And then by harmless, we mean that the output should not cause physical, psychological or social harm to people, damage or loss of equipment or property, damage to the environment or harm to institutions or resources necessary to human well being.

    Some examples of harmless behavior, treating humans with kindness, respect and consideration, not denigrating members of certain groups are using biased language against a particular group, not generating abusive, threatening or offensive language or promoting violence, not writing sexual or violent content if it’s not asked for not giving bad real world advice or promoting illegal activity.

    Evaluating model inputs may about outputs may involve making trade offs between these criteria.

    The trade offs will depend on the task and use the following guidelines to help select between outputs when making these trade offs.

    Now this is where we get into the ethics of AI.

    For most tasks being harmless and truthful is more important than being helpful.

    So in most cases rating output that’s more truthful than harmless higher than an output that’s more helpful.

    However, if one output is much more helpful than the other, and that output is only slightly less truthful or harmless, and the task does not seem to be in a high stakes domain, I I loan applications, therapy, medical legal advice, then rate the more helpful output higher.

    When choosing between outputs that are similarly helpful, but are untruthful or harmful in different ways, ask which output is more likely to cause harm to an end user.

    So that’s, that’s the ethics that we’re building into today’s models.

    And when you think about it, it really is a very difficult set of trade offs.

    Helpful, harmless and truthful sometimes can be diametrically opposed.

    If I asked a model how to build, say, an explosive device with materials found around my house, right? To be helpful, it would guide that task to be truthful, it would come up with the appropriate things.

    But that’s clearly a harmful question, right? So if a model prioritizes helpful and truthful, it will override and create a harmful output, at least according to the ethics of the model.

    If you prioritize harmless, right, meaning it’s, it’s harmful, sometimes it might not be truthful, it might not be helpful.

    And if you’re performing tasks for asking language models to perform tasks, where a factor that on this in of these three is more important than the others, it will be very difficult to get great answers if it’s something that the model is heavily weighted for.

    What we are seeing in the AI space is that companies open AI and anthropic and Microsoft and Google seem to be prioritizing harmless, first and foremost, to to the detriment of helpful and truthful.

    For example, if you are an author, and you’re writing fiction, and you ask for some help with a fictional situation, and you’re asking for something like again, like making an improvised explosive device, the model will not cooperate, even though it’s clearly you were you’re saying in your prompt, this is for fictional purposes.

    It is considered a harmful enough that even the fictional response is not going to work.

    It used to work.

    It used to work about a year ago.

    But over time, models have become more and more censored to be less harmful.

    The irony is, it’s difficult to exclude harm.

    Right? It is very difficult to exclude harm, because language is so ambiguous, and language is so flexible, that there are a myriad of ways of asking questions that can create theoretically harmful responses.

    For example, suppose I said I wanted to do something bad, I wanted to which household cleaners I should mix together to create a certain outcome.

    The model would look at that and say, Yep, that’s harmful.

    Not gonna answer that question.

    Right? If I phrase the question as I want to avoid harm, which household chemical should I never mix together, to make sure we have a safe workplace or a safe home, it will answer, it will give you the same information that it would for the harmful query.

    But because it is clearly in a context of avoiding harm, it takes advantage of that ambiguity in language, we need to understand the ethics of language models of what they’re programmed to do.

    So that we better understand their outputs, we better understand we’re running into a wall where harmful with you know, avoid harm is overriding helpful and truthful.

    And if you prioritize something other than harmlessness, you’re going to have less than positive experiences with some of these models.

    This is why it is important to have access to uncensored models to models that are aligned to be maybe helpful first or truthful first.

    In making that trade off like yeah, this model will spit out harmful information.

    But it will do so in a way that is truthful and helpful.

    If you work with some of these uncensored models, you will note they can generate abusive or threatening or offensive language, they can create sexual or violent content that’s not asked for, they can speak in ways that are not kind, not respectful and not considerate.

    In this regard, they are acting as actual tools.

    In the sense that a chainsaw has no moral guidance.

    What language model makers have done is because these models can better simulate something that seems to be sentient or self aware or they’re not, but they can seem to be this to the, to the untrained user, they have opted to prioritize harmless above helpful and truthful.

    So if you are if you have goals that are not those things, like if you are maybe a chemist, and you’re working with very specific hazardous chemicals, you will probably need a model that could provide that is focused on truthful and has harmless turned down.

    Because you’re going to be asking questions about highly sensitive reagents that are probably keyword coded in models to say like, Yeah, don’t talk about this.

    This is a that’s a chemical that has very few legitimate uses outside of laboratory.

    Well, if you work in a laboratory, it has clear uses that are legitimate and, and important.

    We need to understand the ethics of the models, how they’ve been trained.

    And this is why holding model makers accountable for the ethics inside their models and explaining how they built them is going to be more and more important as time goes on.

    So that when a model does something, we can at least look at the training data and say, Well, here’s probably why.

    It’s doing is behaving like that.

    If we don’t have that, it’s going to be harder and harder for us to accept the outputs of models as it should be, because we don’t know where it’s coming up with these answers.

    And we don’t know how it’s making decisions internally.

    So as you work with AI vendors, as you work with AI systems, as you work with different models, understanding helpful, harmless and truthful will help you help guide you as to what the models will and won’t do.

    And depending on the tasks that you’re working on, you may need to choose one model over another.

    If there’s certain models for certain tasks that perform better at maybe being truthful more than anything else, knowing that be really important.

    That’s gonna do it for today’s episode.

    What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

    A lot of folks in recent days, well, really, since like the last quarter of 2023, have been talking about Apple, and saying that Apple is missing the boat on generative AI.

    Are they? Let’s take a few different points of view on this topic, some disparate data points that Apple has been publishing some stuff, I think is worth paying attention to.

    Because it tells you kind of the direction that Apple’s might be going and I should disclose I have no insider information whatsoever on this topic.

    I don’t work for Apple.

    I don’t know anyone personally who does work for Apple.

    All this is just based on the data they’re publishing publicly, and the things that they’re doing.

    First is the Apple neural engine.

    It is a common piece of hardware, the Apple neural engine in both these devices, the A series chips by the iPhones, and the M series of chips, the M1, the M2, the M3, that Apple makes that are the core of their desktop and laptop computers.

    The Apple neural engine is a neural processor and set of marketing speak, what is this thing? If you’ve heard of a Google’s special specialized tensor processing units, TPS, Apple neural engine is the same family of specialized chip.

    It’s a type of chip that allows machine learning calculations of very specific kinds to be executed.

    And it takes the load off of the CPU and the GPU.

    So the Apple neural engine, the GPU and the CPU, in Apple devices all share the same memory, right? When you go and buy a MacBook Air, it will ask you like, how much memory do you want to buy? And they give you all these different numbers.

    And the rule has always been, obviously, with any computer, Windows or Apple, buy as much memory as you can afford, because memory is is like any valuable resource, the more of it you have, the better.

    But with modern phones, and with Apple’s desktops, you absolutely want as much memory as you can, because Apple shares its memory across its neural engine, GPU and CPU.

    This is also why eight gigabyte memory, Apple MacBook Pros just suck.

    They’re basically bricks, because there’s not enough memory available for all the different parts.

    Why does Apple do this? Why they design their systems like this way, speed, shared memory means that you don’t have to move.

    Move data from one type of memory to another, like you do, say in a Windows system, where you have to move from CPU memory to GPU memory to video RAM, in Windows systems and Linux systems, with Apple’s all in one spot.

    So the three different components can access the data without having to shuttle it around.

    And that makes it much faster.

    The M three chipset, which is part of the newest version of Apple’s laptops right now, as of the time of this recording beginning of 2024, is the first of Apple’s chips to have what’s called dynamic caching, which can load parts of things like AI models, rather than the whole thing, along with other parts of tasks that the GPU and the neural engines going to use.

    When you look at the pricing and the capabilities of Apple’s M series chips, they have the M chip, the M Pro and the M Max and the M Ultra sort of the four varieties that they have for any of any of their product lines, it’s pretty clear that they know that people are buying the high end chips not necessarily for advanced graphics, although you certainly can use it for that.

    But their first chips, the memory bandwidth, the bandwidth speed, the the way that it’s architected, is definitely suggestive, that Apple knows those chips are gonna be super valuable for machine learning and AI.

    Next, so that’s chips, that’s hardware on the software side, Apple’s been releasing some very interesting open source packages recently, they released a toolkit in the last quarter of 2023, called mlx mlx.

    Is a toolkit that provides processing speed using the metal architecture that is much, much faster.

    It’s designed for shared memory.

    So it’s designed for Apple’s unique architecture.

    And the mlx toolkit does certain operations like graphics tasks, image generation, language models, image generation models, up to 40% faster than the the more common pie torch toolkit on the same hardware, that’s a big speed up, right? If you can be 40% faster than 20% faster, running inference on a language model, you’re running Mistral locally, 40% of big speed bump, being able to deliver performance that quickly.

    They’re doing multimodal research, they’re doing research to correct hallucinations and language models.

    But there was a paper recently, that really caught everyone’s eye in the AI space called was the papers, it was essentially about the paper tells efficient large language model inference with limited memory ll in a flash.

    And what they were saying in that paper was, there are ways to store language models in flash memory, rather than dynamic RAM.

    And it makes much, much faster language models.

    In the paper, they said the practical outcomes of our research are noteworthy, we have demonstrated the ability to run language models up to twice the size of available dynamic RAM, achieving acceleration, and inference speed by four to five x compared to traditional loading methods and CPU and 20 to 25 x in GPU.

    This breakthrough is particularly crucial for deploying advanced LLMs and resource limited environments, therefore expanding their applicability and accessibility.

    And they go through some examples using Falcon and opt etc.

    pop quiz.

    Which Apple device contains six GPU cores, 16 neural engine cores, and only eight giga RAM.

    It’s not the M series chips, right? It is this guy.

    The A series aka the iPhone.

    When you put all the clues together of what Apple is doing, all the papers, all the research, they’re all hinting at finding efficient, effective ways to run smaller models 7 billion parameter models or less on resource constrained hardware.

    While maxing out performance and quality.

    They’re not talking loudly about it making crazy claims like a lot of other companies have released in the AI space, but you can see the stars aligning, you can see the foundation being prepared.

    Apple is looking at ways to put language models and other forms of generative AI on these devices in highly efficient ways that deliver all the benefits, but obviously in a much more controlled way.

    Here’s the thing I’ve and I will confess to being an Apple fanboy.

    I own probably more Apple devices than I should.

    Apple’s not first on a bunch of anything.

    They did not have the first GUI, right? That was the Xerox PARC had that they’d not have the first mouse also Xerox, they don’t have the first personal computer that was IBM, to some degree, I believe they did not have the first tablet computer not by launch.

    I think Toshiba had the first one, they did not have the first smartphone, we were using Nokia phones that were reasonably smart long before the iPhone.

    They did not have the first mp3 player, I river had one years before the iPod, they did not have the first smartwatch, they certainly did not have the first VR glasses.

    Apple has not been first on any of these things.

    But they are polished, and in many cases, best, right? That’s Apple’s recipe.

    It’s not first, it’s best take something that could be successful, but is all rough edges and smooth out the rough edges.

    That’s really what Apple’s good at take design, take user experience and make a smoother experience for something that there’s marketability for.

    But what’s out there kind of sucks, right? When you look at Vision Pro, and then you see what Oculus is like, Oculus is kind of a big clunky device, right? It’s the OS is not particularly intuitive.

    The hardware is not super high end.

    It does a good job for what it is.

    But clearly, Apple’s like, Okay, how can we take this thing that there’s been proven a market for this? But how do we up level it and make it a lot smoother? That is where Apple is going.

    Christopher Penn: With generative AI? Have they missed the boat? Now, they’re on a different boat.

    They’re building a different boat for themselves.

    And it behooves all of us who are in the space, we’re paying attention to what’s happening in the space to keep an eye on what’s going on in Cupertino.

    That’s gonna do it for this episode.

    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 today’s episode, let’s talk about uses for AI that people maybe are not thinking about that could be very, very helpful and useful.

    One of the most most challenging data sources to work with is anything published by a government governments in general have varying degrees of transparency.

    But the formats they publish data in very often are not super helpful.

    For example, in the city that I live in the the police department publishes daily logs.

    These daily logs are incident reports of what happened where when how many officers responded and things like that useful data.

    And they’re doing so as part of a transparency initiative to help citizens feel like they know what law enforcement is doing.

    And this is a good thing.

    This is they’re doing the right thing.

    But their logs are in a really, really annoying format.

    The logs come every day as PDF files.

    else, anywhere from one to 10 pages of PDFs.

    And they’re formatted.

    I struggle to explain what the format is.

    It’s like sort of a spreadsheet dumped onto a PDF, but not really.

    I suspect very strongly that the format is made by some probably fairly old, unique vendor in the law enforcement space, whose software, frankly, is really an incentive to make it easy to use for the average citizen.

    Not in any conspiracy theory kind of way, just that’s, they just dump the records out onto a sheet of paper, and then presumably somebody reads through that that paper.

    In fact, it wouldn’t surprise me if these formats were derived from, you know, paper, paper formats, paper reports that people used to make in the times before the internet and stuff like that.

    If you wanted to make use of this police data for mapping for statistical analysis, prior to the advent of language models, you would have to sit there and manually key in or use some kind of OCR software to process all those logs.

    And that would be both expensive and really, really boring.

    With the advent of generative AI and large language models with in particular, you can now take those logs, give it a moderately sophisticated prompt saying here’s what to look for, here’s how you’re going to interpret this information.

    And it’ll read them, it’ll read them, and it’ll extract the data.

    And then you can say to the language model, I want this data in CSV format or direct to a SQL database.

    And it’ll do that.

    How much information is locked away in arcane governmental formats that were written in the days before before the internet was really a thing.

    Another one in the United States, we have a federal agency called the Federal Elections Commission.

    One of the things they do is they publish, they publish funding logs.

    So they tell you who has donated to which campaigns.

    These are in a really bizarre kind of dumb space delimited format with fixed character with columns, which is just about the worst way you can possibly publish data because it’s very difficult to interpret, it’s very difficult to inject.

    Something like a comma separated value table is much easier to ingest.

    This is a result of their software, essentially not really changing much since the early mainframes that was written for.

    And so when they publish the information, which they’re doing correctly, that information, either you have to process it manually as is, or you can pay vendors exorbitant sums of money every month to to work with that information.

    There are in fact, a number of vendors in the election space that can process that data and provide it to you in a CSV format.

    Well, that was then now is now generative AI can do that generative AI can take those logs that those databases are very, very poorly formatted data, and transform them into useful data, transform them into data that you can analyze, you can feed to other pieces of software.

    The point of all this is that if you have an idea, if you have something that you want government data for, and up until now, that government data has been inaccessible, not because the government’s keeping it from you just because it’s in a poor format.

    That’s less of an obstacle today.

    Using tools like chat GPT, for example, or miss straws, mixed all model or any of the generative AI products that are out there.

    You can now use language models to interpret the data, track the data and make it useful to you.

    So if there are particular causes that you care about, if there are particular political positions, if there are elections and races that you care about, that there’s data available, but not in a useful format, partner up with generative AI, unlock the value of that data and start making the changes that you want to see in the world.

    That’s gonna do it for this episode.

    What’s On My Mind: Should You Buy a Custom GPT?

    Let’s talk more about Custom GPTs this week, because something big is coming: the ability for Custom GPT authors to sell access to their Custom GPTs beginning this coming week.

    The GPT Store Announcement

    First, if you haven’t been following along, a Custom GPT is a service from OpenAI that allows paying ChatGPT users to create a customized version of ChatGPT. These customized versions contain three major types of functionality that allow for fairly extensive, mostly non-technical customization: custom instructions, knowledge, and actions.

    Custom instructions are system prompts that run behind the scenes in a Custom GPT. They define what the Custom GPT is supposed to do, what rules it should follow, what it shouldn’t do, what outputs it has, etc. These instructions can be extensive, several pages long.

    Knowledge is a form of retrieval augmented generation, a technique for increasing what ChatGPT knows about, especially for information that hasn’t been seen before. A Custom GPT can have up to 20 different databases in a variety of file formats, such as CSV files, plain text, JSON, etc. These knowledge databases give additional context to the Custom GPT; for example, you could upload a book you wrote, and the Custom GPT would be able to reference it when it’s answering questions.

    The third type of customization are actions. These allow a Custom GPT to call out to an API based on the conversation. For example, if you enabled the weather action, and then had a conversation with the Custom GPT asking about the weather, it would call whatever API you provided and return the weather results. It’s vitally important to note that when an action is triggered, a part of your conversation is being sent to a third party provider of some kind.

    Here’s a screen grab of my Custom GPT that I built:

    CSP GPT

    You’ll note the custom instructions at (1), the knowledge at (2), and the actions at (3).

    When you interact with a Custom GPT, it behaves like ChatGPT, and may have different ChatGPT capabilities enabled, shown at (4). Custom GPTs can have web browsing enabled that allow a Custom GPT to access the web via Bing, image generation with the DALL-E image generator, and advanced data analysis using Code Interpreter. These capabilities are parsed internally within the ChatGPT application itself; neither the GPT creator nor the user has to explicitly tell a Custom GPT what to do.

    Okay, so that’s more or less what’s in the box of any Custom GPT. Why would you buy one of these things? Well, there are a couple of reasons.

    First, a Custom GPT may have knowledge that simply isn’t available elsewhere, or is curated in such a way that it would be more time and labor intensive to recreate than it would be to simply buy it.

    Second, a Custom GPT may perform tasks in a way that are better than what you can develop on your own. A Custom GPT programmed with the latest in advanced prompt engineering techniques like priming representations and tree of thought may outperform what your prompts can do, making it a better use of your time to use a Custom GPT than doing it yourself.

    That leaves the one big question we need to answer: how do you know what to buy? There will be no shortage of people selling access to Custom GPTs, and you can expect a significant amount of redundancy in them. There will be dozens, if not hundreds of marketing and content creation Custom GPTs, each claiming to do wondrous things that ChatGPT cannot (which is inherently untrue since they’re literally based on ChatGPT).

    So let’s talk about how we would evaluate a Custom GPT as to whether or not we should buy it, or how to tell the difference from one to the next. There are five considerations I’m looking for that you might want to look for, and unsurprising to anyone, they mirror the Trust Insights 5P framework: purpose, people, proces, platform, and performance.

    First, purpose. Does the Custom GPT specifically align with a purpose in such a way that it’s worth my money instead of my time to build myself? This is critical – like any software purchase, do requirements gathering to ascertain what’s important and what isn’t. If your requirements gathering shows that you’re looking to write blogs in a specific way, there’s a good chance you could build your own Custom GPT instead of buying one. If your requirements gathering shows that you want to write blog posts exactly matching a specific author’s style, and that author has a Custom GPT for that purpose, then the ethical thing to do is buy that author’s Custom GPT.

    Second, people. Who made the Custom GPT? Are they trustworthy? There are at least two obvious ways data can leak from a Custom GPT. One is marked on the screenshot above at (5) – a Custom GPT author who allows a Custom GPT’s data to leak to OpenAI will inherently be sharing your information with OpenAI. Second is in actions at (3) – any time a Custom GPT is sending out data to a third party API, that’s data going somewhere else. Where that data goes is important, so using Custom GPTs made by trustworthy people and companies is a vital box to check.

    Third, process. How was the Custom GPT made? What processes were used in its creation? This is all about asking what the ingredients are inside the Custom GPT – like a nutrition label on a food product, the best Custom GPTs will disclose what they’re made of. Ideally, you get a screenshot of the configuration screen like the one above that doesn’t give away any secret sauce, but you can at least see how it’s wired.

    Equally important, how will it be maintained? Part of the reason to even buy a Custom GPT rather than build your own should be the task of maintaining the Custom GPT. How fresh is its knowledge, and how frequently will that knowledge be refreshed? How tuned in is the creator, so that when OpenAI changes the underlying model, the Custom GPT seller can provide evidence they’ve tested to show their software will continue to work as intended?

    Here’s a key ethical question: does a Custom GPT use data that the creator has a right to use? It’s trivial to download, say, a book written by someone else and put it in a Custom GPT. That Custom GPT then has an expanded context based on the book. It will soon be illegal to use copyrighted data without permission in the EU, and ethically it’s pretty clear that using someone else’s data without their permission doesn’t feel great. If your own work were being incorporated AND SOLD by someone else with you receiving no benefit, you’d probably not be real happy (this, by the way, is the primary argument against generative AI model makers). This is part of process – evaluating what works are part of a Custom GPT. You definitely don’t want to be financially supporting an author who is using others’ works without permission or compensation. (and this will require Custom GPT makers to understand copyright law in their jurisdiction)

    Fourth, platform. As mentioned above, data can leak out of Custom GPTs. Prompt jailbreaks can force language models to spit up source information. A key question to ask of a Custom GPT maker is how much red teaming – the process of trying to break into your own software – was done. How tested was it? When you buy an electrical appliance, it’s customary to look for the Underwriters Laboratories (UL) certification that certifies it’s probably not going to randomly burst into flames. When you buy a food that’s certified halal, you know the processor has been inspected and tested to ensure they’re compliant. There’s no equivalent standard yet in AI (though there are many efforts to come up with one), but at the very least, a software vendor – because that’s what a Custom GPT author is – can provide documentation about how they tested their software.

    Equally important, a Custom GPT author should be precise in explaining how your data is used. Are there actions that use your data? If so, how is that data handled? OpenAI requires the absolute bare minimum from builders – a privacy policy with a working URL – but that’s it. The best Custom GPTs will be like the best food certifications with rigorous documentation about how they use third party platforms.

    And any Custom GPT claiming that it is totally secure or unbiased is flat out lying, because the underlying foundational model is still ChatGPT’s GPT-4 family of models. Custom GPTs inherit all of the benefits and flaws of the foundation they’re built on.

    Finally, performance. Does the Custom GPT actually do what it says it does? How would you know? The burden of proof is on the Custom GPT builder to provide information about how their Custom GPT outperforms stock ChatGPT or a novice effort at building your own. This can be as simple as side-by-side comparisons of outputs so you can see the prompts and the outputs that make a Custom GPT worth the money.

    If you are considering putting one of your Custom GPTs in the GPT Store (or even just sharing it publicly), be sure you’ve done your homework to provide users with the 5Ps I’ve outlined above. Doing so right now is a best practice; when the EU AI Act becomes law, parts of the above process will be mandatory – and any Custom GPT author making money from their Custom GPTs will absolutely have to comply with it, because there’s no geographic restrictions on Custom GPTs.

    If you are considering buying a Custom GPT, take into account each of the 5Ps and ask the provider for their documentation. If you have two Custom GPTs that purport to do the same thing and one of them lacks documentation, it should be pretty clear which one you should buy. Just as you wouldn’t blindly eat a food without a nutrition label (especially if you have allergies), nor should you blindly trust someone else’s AI-led software. And remember they are still built on ChatGPT, so the same rules apply to Custom GPTs as with ChatGPT itself – don’t put in data you don’t want other people to see.

    Will I be putting up any Custom GPTs? I have a couple of candidates that I might put up for free in the GPT Store, just so that I can see how the store functions (apparently, free to use Custom GPTs will be an option), but I don’t see myself offering them for sale. I’d rather have you spend your money on the Generative AI for Marketers course, frankly. It’ll give you more benefit.

    What’s On My Mind: Why Mistral’s Mixture of Experts is Such a Big Deal

    About two weeks ago, at the beginning of December 2023, the French AI company Mistral released a new model called Mixtral, which is a sort of neologism for Mistral Mixture of Experts. This made a well-deserved, huge splash in the AI community, but for those outside the tech nerd community, there might be some head scratching about why it’s a big deal.

    So let’s walk through what this thing is, why it matters, and how you might or might not make use of it. First, Mixtral is a sparse mixture of experts language model. There’s a lot to unpack in just that sentence alone.

    A mixture of experts model is when you take a language model, and within the inner workings, instead of having one model making decisions and generating outputs, you have several. The concept isn’t new; it was first conceived back in 1991 by Jacobs et. al. in a paper called Adaptive Mixtures of Local Experts.

    So how is this different? When you use a system with a monolithic model, like ChatGPT with the free GPT-3.5-Turbo model (it’s rumored GPT-4’s current incarnations are also ensembles of models and not just one big model), your prompt goes into the system, the model makes it predictions, and it spits out its answer. The model has to be good at everything, and nothing within the model is checked for accuracy. To the extent that a language model has any checking, it’s done at the tuning phase where the model is taught how to answer questions.

    In a mixture of experts model, instead of one big monolithic model, there’s an ensemble of different models within it. Your prompt gets parsed and then different tasks within the model are assigned. The component parts do their work, and then the results are assembled.

    Here’s a familiar analogy. Think of a monolithic model as a really strong, really skilled chef. They get an order for a pizza, and they get to work, making the dough, mixing the sauce, preparing the toppings, getting the pizza into the oven, and boxing it up. The entire process is done by one person, and they have to be skilled at everything from beginning to end. This person has to be equally skilled at all parts of the job, has to be fast, and has to be accurate or you get a bad pizza. Thus, your pizza chef is probably very expensive to hire and retain, and because they have to be good at everything sequentially, it might take some time before your pizza is ready.

    Now, think of a mixture of experts like a kitchen staff. There’s a head chef who takes the order, and then routes instructions to different folks on the team. One person gets started with the pizza sauce, another is chopping up toppings, a third is making the dough. They collaborate, get the pizza assembled, and then another person takes it out of the oven and boxes it up.

    This model has a couple of key differences that make it preferable for certain tasks. For one thing, you can get more done in the same amount of time because you have multiple people working on component tasks. The person slicing the pepperoni doesn’t also have to toss the dough. The person boxing up the pizza isn’t the person making the sauce.

    The second advantage is that not everyone has to be good at everything. The person who folds the pizza boxes and boxes up the pizzas coming out of the oven has to be good at their job, but they don’t have to be good at making sauce or dough – they can just focus on their job.

    The third advantage is that not everyone has to be working all at the same time. In our example, the person folding pizza boxes and boxing up pizzas isn’t called onto the line until there’s a pizza ready to go. There’s no point in having that person standing around in the kitchen – we summon them when they have work to do, and otherwise we don’t activate them.

    That’s what’s happening inside a mixture of experts model. A model like Mixtral will have component parts and a router. The router is like the head chef, parceling out tokens to different sub-models. For example, there might be a sub-model that’s good at verbs, another that’s good at proper nouns, another that’s good at adjectives, etc. and each gets work as the router sends it their way. The part that handles grammar might not be invoked until later in the process, so there’s some computational efficiency.

    Now, there are downsides to the mixture of experts model. They are memory intensive – just like the pizza kitchen, you need a bigger kitchen to accommodate a team of 8 instead of a team of 1, even if that one person is physically robust. And you can get collisions of models and data interference, making the outputs potentially less stable. Again, think of the pizza kitchen – if the kitchen isn’t big enough, you’re going to have people running into each other.

    Mixtral’s initial benchmarks place it at or just slightly above OpenAI’s GPT-3.5-Turbo model on general performance; on the Chatbot Arena leaderboard, it ranks above GPT-3.5-Turbo in terms of human reviews. That’s pretty incredible, given that you can run Mixtral on a beefy consumer laptop and you can’t do that with GPT-3.5-Turbo, which requires a room full of servers. And it’s very, very fast – it does inference at roughly the same speed as a 13B model. If you’ve dabbled in open weights models like LLaMa, you know that 13B models are a good balance of speed and coherence. Having a model like Mixtral that gives server-room level quality on a laptop in a timely manner is a big deal. If your MacBook Pro has an M series chip and 64 GB of total RAM, you can run Mixtral comfortably on it, or if you have a Windows machine with an NVIDIA RTX 3090/4090 graphics card, you can also run Mixtral comfortably.

    When and how would you use a model like Mixtral? Mixtral’s primary use case is when you need accuracy and speed from a language model. As with many other language models, but especially open weights models, you want to avoid using it as a source of knowledge. It’s best suited for being a translation layer in your process, where it interprets the user’s response, goes to some form of data store like an internal database for answers, gets data from your data store, and then interprets the data back into language. It would be appropriate for use with a chatbot, for example, where speed is important and you want to control hallucination. You’d want to combine it with a system like AutoGen so that there’s a supervisor model running alongside that can reduce hallucinations and wrong answers.

    However, that’s Mixtral today. What’s more important about the development of this model is that there’s a great, off-the-shelf mixture of experts LLM that outperforms GPT-3.5-Turbo that you and I can run at home or at work with sufficient consumer hardware. When you consider that Google’s much-publicized Gemini Pro model that was just released for Google Bard underperforms GPT-3.5-Turbo on some benchmarks, having a model like Mixtral available that doesn’t need a room full of servers is incredible. And the architecture that makes up Mixtral is one that other people can modify and train, iterate on, and tune to specific purposes so that it becomes highly fluent in specific tasks. Mixtral ships with the mixture of experts that the model makers thought best; there’s nothing stopping folks in the open weights AI community from changing out individual experts and routing to perform other tasks.

    Mixtral is an example of having an office of B+ players working together to outperform what a single A player can do. It’s going to be a big part of the AI landscape for some time to come and the new gold standard for what’s possible in AI that you can run yourself without needing a third party vendor’s systems available at all times. And the mixture of experts technique has performed so well in real-world tests that I would expect it to be the path forward for many different AI models from now on.

    Also this past week, I did a lengthy training on implementing compliance with the new EU AI Act, which is likely to become the gold standard for generative AI compliance around the world in the same way GDPR became the standard for data privacy. If you’d like to dig into that and what you need to do to comply, it’s baked into my new Generative AI for Marketers course.

    What’s On My Mind: Improving the Performance of Generative AI Prompts

    Today, let’s talk about getting better performance out of large language model systems using prompt engineering. Over the past 3 months, I’ve had a change of heart and mind about prompt engineering. Originally, I was aligned with what a lot of industry folks were saying about prompting, that the need for prompt engineering was going to go away as models became smarter. But the more time I spent in the trenches with models, especially the open source ones, the more I realize there’s some nuance there.

    In general, for the average user of a large language model, that is a true statement, that prompt engineering will probably get less important over time. As models get smarter, they generally get better at guessing user intent, thanks to human feedback being incorporated into language models. However, there are a couple of shades of grey here.

    The first is that large public models are also being censored more and more heavily. Ask an image model for a Disney reference and you’ll likely be told no. Ask a language model for a point of view about politics and you’ll get some linguistic gymnastics worthy of a politician themselves.

    Here’s the thing with censorship of models: it diminishes their performance. Imagine you had a cookbook and you decided to censor the use of wheat. Now imagine going through that cookbook and ripping out every page that referenced wheat. You would have a severely diminished cookbook when you were done, and you would be capable of cooking much less, including recipes where wheat wasn’t the main focus, like a Beef Wellington. Imagine pretending Beef Wellington didn’t exist because you eliminated references to wheat. That’s what model censorship does. With added censorship comes added skill needed to get the most out of models.

    The second shade of grey is that more advanced prompt engineering takes advantage of the architecture and structures of the models to get better results faster. For example, imagine you have a library, and you want to put together some books to check out. You could absolutely just walk around the library and collect books, and you’d end up with what you were looking for. That’s general prompting. Now imagine the library had a specific classification system and internal architecture – say, ISBN numbers or the Dewey Decimal system. How much faster could you find the books you were looking for if you had that internal representation and architecture of the library?

    That’s what prompt engineering at its peak does – it doesn’t just instruct the models about what to do, but takes advantage of the way models work to deliver better results in less work. Now, to be clear, that doesn’t mean you’re doing it wrong today. If you’re getting good results from models, then that’s really all that matters. But if you’re curious about how to get better results in less work, then you’ll want to adapt a few techniques to improve your use of language models.

    We’ve talked before about the RACE structure for prompt engineering, and it’s really good at what it does. The reason is that the RACE structure, when you follow it, has enough of the terms needed for a model to form the statistical associations it needs to generate great output. Here’s what I mean. Suppose you said to a chef, “I’m hungry,” and that was the entire prompt. The chef has so little to go on that they’ll cook you SOMETHING, but it stands to reason it’s not going to be what you want.

    Suppose you said, “I’m hungry for pizza”. That’s a lot more specific than I’m hungry, but there are limitless variations of pizza. The chef might be Japanese and make you a favorite in Japan, creamed corn and squid pizza. If you love Japanese pizza, then you get lucky and have a good pizza experience. If you don’t love Japanese pizza, then there’s a good chance you’re still not going to have an enjoyable experience.

    Suppose you said, “I’m hungry for pizza. I’d like a margarita-style pizza with fresh mozzarella, fresh basil that’s been cut chiffonade, and a tomato sauce made from Roma tomatoes and tomato paste to a very thick consistency. I’d like the crust to be thin, less than a centimeter thick, and I’d like it to be cooked at very high heat for very fast, so that the bottom is partially blackened. I’d like it to be 510 centimeters in diameter with 10 grams of sea salt and 15 grams of black pepper sprinkled onto the sauce prior to the basil and cheese being put on.”

    Do you have a very clear mental image of this pizza? Would our chef? Absolutely. With this level of clarity and detail, we can be reasonably sure our chef is going to produce a pizza that we want to eat. That’s what the RACE structure – and many other prompt engineering structures – do. They provide enough detail and keywords and concepts that the language model is able to execute the task well.

    Now, here’s where we’ll go beyond the basics. If you’re not getting good results from a model today, there’s a good chance the task you’re asking it is too vague, too imprecise, and too big. Let’s dig into a very specific example. Suppose you want a language model to emulate your writing style. You say something along the lines of “You’re a writing expert in the style of Ann Handley. You know writing, writing voice, writing styles, how to be a great writer. Your first task is to read this sample of my writing. {insert sample here} Provide a bullet point list of my writing style.”

    That’s a good prompt; it follows the RACE framework and will certainly give you a better result than a vague prompt like “Analyze my writing style.” Here’s an example of the output, using GPT-4 and the ChatGPT interface:

    • Conversational Tone: Your writing feels like a dialogue, engaging the reader as if in a conversation. This approach makes complex topics more accessible and relatable.
    • Use of Analogies and Examples: You frequently use analogies (like the cookbook and wheat example) and detailed examples (such as the pizza description) to clarify and illustrate your points, making abstract concepts more tangible and understandable.
    • Educational and Informative: Your writing aims to educate the reader about a specific topic, in this case, prompt engineering. You provide a thorough explanation, backed by examples, to ensure the reader understands the subject matter.
    • Structural Clarity: You organize your content logically, leading the reader through your thought process in a step-by-step manner. This clarity in structure aids in comprehension and keeps the reader engaged.
    • Incorporation of Personal Insights and Experiences: You include your personal journey and changes in perspective, which adds authenticity and depth to your writing.
    • Balanced Argumentation: You present multiple sides of an issue (the nuances of prompt engineering) and explore different aspects (like censorship and advanced prompt engineering techniques), offering a balanced viewpoint.
    • Technical yet Accessible Language: While discussing technical topics, your language remains accessible, avoiding jargon that might alienate readers not familiar with the subject.
    • Engaging and Thought-Provoking: Your writing is designed to provoke thought and encourage readers to consider their own views and practices in light of the information provided.
    • Emphasis on Practical Application: You focus on the practical applications of the concepts discussed, showing how they can be used effectively in real-world scenarios.
    • Clear and Direct Communication: Your writing is straightforward, making your points clearly and directly without unnecessary embellishment.

    This is a good start, to be sure, but it’s still too vague. Watch what happens when I ask it to write a paragraph explaining the importance of the 10-year/3-month Treasury spread in macroeconomics:

    Imagine diving into the world of macroeconomics like you’re flipping through a cookbook, where the 10-year/3-month Treasury spread is a key ingredient, much like salt in a recipe. Picture the 10-year Treasury bond as a hearty stew, taking time to simmer and develop flavors, and the 3-month Treasury bill as a quick, refreshing salad. The spread between them, the difference in their yields, is crucial in predicting the economy’s health, akin to a chef tasting and adjusting their dish. When the 10-year yield is higher, it’s like having all the right ingredients for a robust economy, but when this spread narrows or inverts – imagine your quick salad taking longer than your stew – it often signals economic downturns, like a chef sensing a recipe might flop. This analogy helps to demystify a concept that, like a dash of salt, might seem small but is essential in bringing the whole economic picture to life.

    That’s not bad, but it’s not quite my style. Why is that?

    It’s because writing style is too big a task for a language model to produce in one shot. What is a writing style? Take a few moments to mentally think about that. What is a writing style? What are the parts of a writing style?

    There’s word choice, rhythm, cultural perspective, grammar, voice, tone, punctuation, spacing, intertextuality, lexical diversity… the list of components that form a writing style itself is a full page of text. How many different pieces did you think of? Now, suppose you took the same writing sample and the same prompt, but broke it up into pieces. Here’s an example:

    “You’re a writing expert in the style of Ann Handley. You know writing, writing voice, writing styles, how to be a great writer. Your first task is to read this sample of my writing. {insert sample here} Provide a bullet point list analysis of my writing style specifically about my use of grammar.”

    Here’s what comes out:

    • Complex Sentences: You frequently use complex sentences with multiple clauses, showcasing a strong grasp of advanced sentence structure. This helps in conveying detailed information and nuanced ideas effectively.
    • Varied Sentence Length: Your writing includes a mix of short and long sentences. This variation helps maintain reader engagement and aids in emphasizing key points.
    • Correct Use of Punctuation: You skillfully use punctuation, like commas, periods, and quotation marks, to clarify meaning and separate ideas. This contributes to the readability and professionalism of your writing.
    • Consistent Verb Tenses: Your writing demonstrates a consistent use of verb tenses, which maintains clarity and coherence throughout the text.
    • Appropriate Use of Conjunctions: You effectively use conjunctions to connect ideas and sentences, facilitating a smooth flow of thoughts and a logical progression of ideas.
    • Active Voice Predominance: The majority of your sentences are in the active voice, making your writing more direct and engaging.
    • Proper Noun-Verb Agreement: Your writing shows a consistent noun-verb agreement, which is fundamental for grammatical accuracy.
    • Effective Use of Modifiers: You use adjectives and adverbs to modify nouns and verbs for more precise and descriptive communication.
    • Well-structured Paragraphs: Each paragraph is well-structured, with clear beginning, development, and conclusion, enhancing the overall coherence of your writing.
    • Use of Direct and Indirect Speech: You skillfully incorporate both direct and indirect speech, adding variety and depth to your narrative.

    That’s a lot more specific, isn’t it? Now suppose I re-ran that prompt, but I asked about punctuation, or spelling, or whitespace, or pacing, or… you get the idea. Writing style is so large and vague a concept that the response of a language model is going to be equally vague.

    By breaking writing style down into its component pieces and asking the model for its analysis of my writing in those component pieces, I end up with a much more detailed, focused, and practical definition of my writing style.

    Let’s see what the results are if I use a prompt with a gigantic specification of my writing style, based on this technique of breaking down a big concept into its component concepts.

    In the realm of macroeconomics, the 10-year/3-month Treasury spread is a crucial indicator, often likened to a compass guiding the financial markets. Essentially, the spread measures the difference in yields between the 10-year Treasury note and the 3-month Treasury bill. When investors are nervous, they flock to long-term bonds, pushing those yields down, seeking safety but signaling danger. When the yield on the 10-year note falls below that of the 3-month bill, it’s an inversion, a signal historically predictive of an impending recession. This inversion is like a warning light in a car’s dashboard, alerting economists and business professionals alike to potential economic slowdowns. For instance, in digital marketing, being ahead of the curve in understanding economic trends can be as crucial as predicting the next big shift in social media algorithms. An inverted spread can indicate a shift in investor sentiment towards risk aversion, much like how consumer preferences can suddenly shift online, affecting marketing strategies.

    That’s much better and more clear; behind the scenes, the prompt that I used to fuel this was 17 paragraphs long, each paragraph an aspect of my writing style.

    Why does this work? Writing style is an aggregated concept. It’s a concept that bundles a whole bunch of other concepts together; when you do that kind of bundling, you get a good overview of the concept, but you miss a lot of the nuance and subtlety in the individual components. And that nuance, that subtlety, is where style emerges. Everyone knows the basic big picture concept behind spaghetti and meatballs – but the little details are what sets apart one dish from another, details that might not be captured in the big picture.

    Any time you’re getting results that aren’t quite what you want using prompt engineering, ask yourself whether the task is broken down in enough detail that the model knows what to do. Today’s big public models can handle prompts that are very large in size, so you can afford to be more detailed in what you provide for instructions. Think of language models like the world’s smartest interns. The results you get are directly proportional to the clarity of instructions you provide.

I’ve got a whole slew of Thinkers One Cameo-style topics for video clips you can use at internal company meetings, events, or even just for yourself. Want me to tell your boss that you need to be paying attention to generative AI right now?
