In today’s episode, you’ll dive into the fascinating world of generative AI and learn about two powerful techniques: RAG and fine-tuning. You’ll gain a clear understanding of how these techniques differ and when to use each one to enhance the capabilities of AI models. I’ll provide easy-to-understand analogies to help you grasp the concepts and guide your AI strategy. Tune in to discover how to unlock the full potential of generative AI for your specific needs!
You Ask, I Answer: RAG vs Fine Tuning in Generative AI?
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, Dale asks, “When should we use RAG? And when should we use fine tunes?”
Okay, this is a very technical generative AI question. And to tackle that, we should probably do some level setting for people who aren’t Dale. First, what do these words even mean?
RAG stands for Retrieval Augmented Generation. It is a way to add new data to an AI model and even tell the model to look at that data first when it’s building its responses. There are tools, for example, like NotebookLM or anything LLM in query mode where you can say, “Here’s a bunch of my documents, here’s all my newsletter issues, I’m going to prompt you, and you have to look at my stuff first, or maybe you have to look at only my stuff and nothing else.” That’s Retrieval Augmented Generation.
Fine-tuning is a way to give a model a huge number of questions and answers and say, “You’re going to learn how to do this specific task. I’m going to train you to do this specific task.” Maybe it is teaching a model how to spell, and so you would give it questions like, “How do you spell the word strawberry?” And so on. “How many hours are in strawberry?” And you have the answer, and it would recondition the model to behave differently.
Here’s the easiest way to think about this conceptually, that will help understand these two strategies. Imagine an AI model like the one that powers ChatGPT, like a library. When you prompt the tool, you’re like talking to the librarian.
For Retrieval Augmented Generation, we’re assuming the librarian’s really good at their job. They go into the stacks and find books. But we know that the library doesn’t have the books that we want information from. So we build a new wing on the library, and we add the new books. And now the librarian, whose job hasn’t changed, knows, “Oh, let’s check out the new wing first, and provide answers from that.”
That’s Retrieval Augmented Generation. It’s very useful for when the model does what you want but doesn’t have the right information to accomplish its task.
Fine-tuning is like taking the library and saying, “Hey, we need you to teach a kid’s class on gardening.” And the librarian’s like, “That is not at all what I’m trying to do. I go and get books. I don’t teach kids gardening or anything.” And you would say, “Okay, let’s teach you how to teach kids. Let’s have you go through some education classes, let’s do student gardening classes and things.” And after a very long period of time, the librarian’s like, “Okay, I can now also teach kids how to garden.”
We’ve changed the librarian’s behavior. They still can go and get books, but now they can teach kids’ classes on gardening as well. That’s what fine-tuning does.
And there’s a few different strategies for that. Fine-tuning is useful when you want to change the behavior of the model to help it learn how to do something it doesn’t know how to do. Which we’ve augmented generation is good for when
Christopher Penn: the model is fine at what it does, but it just does not know where the data is.
Knowing the difference between these two major strategies for how AI works will help you inform your strategy as to which of these two paths you need to pursue if a model is just not doing what you want. If the model can do tasks, but not what you want, because it doesn’t have the data, you use Retrieval Augmented Generation; you give it the data. One of the things I say in all of my keynotes on generative AI is: the more data you bring to the party, the better a model is going to—going to generate good results because it doesn’t have to guess at the data anymore, you’ve given it knowledge. If you’re just not happy with how the model does things, then fine-tune is in order.
And again, you can re-fine-tune the entire model. We can do this thing called building an adapter, a low-rank adapter that is like a plugin to a model that increases capabilities. If you’ve ever used a tool like Adobe Premiere, and you bought a plugin and installed it, and so Adobe Premiere can now do this new thing, that’s essentially what an adapter is for a generative AI model.
So, it’s a good question. It’s a complicated question, but is an important one for how you choose your strategies for changing the results you get out of generative AI.

In today’s episode, you’ll uncover the reasons behind the challenges AI faces in creating truly compelling slide decks. You’ll learn about the limitations of current AI architectures and how they hinder the seamless integration of text and visuals. I’ll also explore the fascinating interplay between reason and creativity and how it affects AI’s ability to craft presentations that are both logical and engaging. Tune in to gain a deeper understanding of the complexities of AI and its potential for future development in the realm of visual storytelling.
You Ask, I Answer: Why Can't AI Make a Nice Slide Deck?
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, literally everyone asks the question, “Why can’t AI make a compelling slide deck? Why can we not make a presentation with generative AI?”
And the answer to this question is complicated. It’s complicated for two reasons.
Number one is an architectural reason. There’s two major architectures of generative AI models right now: there’s one called transformers, and one called diffusers.
Transformers is the architecture that powers many tools like ChatGPT, for example. And what they are is they are token predictors: given a series of input tokens—like pieces of words—they can predict the next word in a sequence. Given a strain of DNA, they can predict what the next base pairs are going to be. Given a sequence of musical notes, they can predict what the next musical note is going to be based on all the data they’ve been trained on. That token prediction is linear, it’s sequential, and it’s based on the context of everything that’s seen before. That’s how a tool like ChatGPT does what it does.
Diffusers, which is the other major architecture that powers tools like Midjourney or Stable Diffusion or DALL-E, are image generators that take a bunch of noise, take some words that have known associated images with them, and then start scraping away pixels until what’s left behind—what’s left behind is ideally aligned to kind of what the prompt was— a dog on a skateboard or something like that.
These two models work very, very differently. And they don’t talk to each other. They don’t talk to each other well. They have difficulty understanding what’s going on. Even multimodal models, like Google’s Gemini, for example, aren’t really truly multimodal in that they can make a round trip. And here’s what I mean.
Go into ChatGPT and say, “Hey, make a picture of a Toyota Prius with four people sitting in the car.” And every time I’ve done this, it comes up with a picture of three people. I’m like, “But it’s four people! I said four people.” It says, “Here’s your picture,” and it’s got sort of three people in it.
Why is it doing this? Because a transformers model can’t see what a diffusers model publishes, and vice versa. There’s no round trip. Transformers can’t see what diffusers have made; diffusers have no true, useful understanding of language. And so these architectures are incompatible.
Now, will that change? Yes.
There are already some laboratory models called transfusion models. There’s also ones called visual language models—there’s one from a Chinese company called Quin that are getting more capable at starting to understand what they see. Pick Straw is another example of a blended visual language model.
And so the architecture issues are going to start getting better. There’s another reason why this is difficult for these AI models, and that has to do with reason versus creativity.
When you’re putting together a presentation, there’s a fair amount of reasoning that goes into it, logic. There’s things like, “Okay, what is the—what is the way to tell the story? What are the beginning, middle, and end of the pathways we want to lead people down? If we want to communicate effectively, we have to tell a story. It has to have a logical flow, some kind of sequencing that makes sense.”
And then we also have to be creative, right? We have to have unique, creative takes on things to make our story and our slides and our presentation compelling. No one wants to watch the same old thing. People want something fresh and new.
Reason and creativity are kind of at opposite ends of the spectrum. Reason is very high-probability things. It’s saying, “Okay, that’s the next most logical thing. What’s the next most logical slide in the slide deck?” Creativity is like, “What’s the unexpected thing that we could throw in that would make this presentation surprising and compelling?”
It’s—uh, I was in my series that I did with my friend Ruby King talking about music, there’s—you can make music that’s highly logical, highly high-probability. It’s boring to listen to because there’s nothing that’s a surprise. You can make music that is highly creative that has all sorts of key changes and tempo changes and things where you listen to it like, “Oh, that’s different. That’s not what I was expecting,” within reason.
And that reason versus creativity is part of the reason why generative AI can’t really do both well at the same time. You have to almost do passes where there’s a reasoning pass to go through first to establish the story, and then there’s a creativity pass, perhaps from a different model that can go through and improve the creativity.
So there’s architecture reasons, and then there’s sort of conceptual reasons why generative AI has so much trouble with a task like building a compelling slide deck.
Will that get better? Yes, over time, it will get better as tools improve for true multimodality. As tools are trained and models are trained on the process of making slide decks, it will improve over time. But right now, it’s still a very hard thing for these tools to do.
So it’s a good question. It’s an important question because it highlights how—how these tools are, in many ways, not like us, not like the way we think. And the sooner we understand that, the deeper we understand that, the better results we’re going to get.

In today’s episode, you’ll explore the intriguing paradox of why marketers, despite having access to vast amounts of data, often struggle to extract meaningful insights. You’ll discover the crucial role that well-defined questions play in guiding data analysis and learn why simply having data isn’t enough. I’ll share a practical framework that helps you transform data into actionable insights and improve your marketing effectiveness. Tune in to unlock the power of your data and make smarter, data-driven decisions!
You Ask, I Answer: Why is Marketing Data Rich but Insight Poor?
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, Brooke asks, “Why is it that marketers are data rich, but insight poor?”
Oh, that’s a good question. A lot of reasons. Let’s talk about some definitions first. What are insights? Think about the actual word insight, like sight within, looking within—looking within something. What are you looking into? You’re looking into your data. And when you look into your data, what are you looking for? Answers. Answers to what? Answers to questions. What questions? Questions like: “How do I get this person to buy more from me? How do I get this person to be happier with my company? How do I get this person to recommend me to a friend?”
These are the questions that we need to have written out and documented so that we know then what to look into in our data. We’re looking for connections in the data, we’re looking for patterns, we’re looking for conclusions. And all of our data that we have doesn’t mean anything if we don’t have questions we need answers to.
Likewise, if we don’t have those questions, we might not even be collecting the data for it. If we are—if we’re concerned about customer loyalty and evangelism and we’re not tracking recommendations in our social media management software, then we can’t answer that question. There’s no way to answer the question with the data we have.
So part—part of the answer to Brooke’s question about why we are insight poor is: we don’t know what we’re looking for. We didn’t ask the questions, we haven’t defined the questions, and therefore we have no—we have nothing to dig for, we have no answers to look for. We just go look at the data and go, “Huh, there’s the data,” and we don’t do anything with it.
Think of data like ingredients. Go into your kitchen, go in your pantry, the ingredients—as marketers, we have no shortage of data, we’ve got data everywhere. Are the ingredients any good? Are they fresh? Are they spoiled? Are they filled with bugs?
Bad data, like bad ingredients, is worse than no data because bad ingredients can make you sick. Bad data can lead you to incorrect conclusions.
Christopher Penn: Do we know what we’re trying to accomplish with the data? Going back to those questions. If our ingredient that we have the most of is flour, are we making a cake, pasta, sourdough bread, salt dough for salmon on the grill? If we don’t know what we’re asking for, if we don’t know what the recipe is, we don’t know what the final outcome is, then the data doesn’t really matter.
Do we have a recipe and process? This matters. This is something that my CEO Katie talks about all the time is: you need to have a recipe. You need to know what your process is, you need to have a recipe to get to that final dish. Again, if insights are answers to questions, we need a recipe for how we turn data into answers.
Do we have a chef with the skills needed to execute the recipe? Can I cook it? Can you cook it? Do you know how? I can give my dog a recipe, but we’re not going to get what we want. I hope he’ll be very happy, and he’ll be eager to help, but he will not bake a loaf of bread. Pretty cool if he could, but again—do you have the right appliances?
If you’re making bread, do you have an oven? It doesn’t matter how skilled the chef is or how great the ingredients are, how good the recipe is, if you don’t have a source of heat, you ain’t baking bread at all.
Same is true with data: if you don’t have the tools to process it, as well as the knowledge of how to process it, you’re going to have a very hard time.
Asking why marketers are data rich, but insight poor is a great question. The answer is the same as why a restaurant is ingredients rich but has no food on the tables for diners to eat. It’s because something broke down in the people, the processes, the platforms, the purpose, and the performance—the Trust Insights 5P Framework, which you can get at TrustInsights.ai/5pframework.
That’s the answer. That’s why we are so data rich, but insight poor because we don’t know how to make the insights. We don’t even know what it is we’re trying to make.

In today’s episode, you’ll discover how to prepare your website for the exciting future of AI agents making purchases on behalf of customers. You’ll learn a surprisingly simple way to make your website AI-friendly, which can also boost your revenue by up to 10% today. I’ll share insights into the connection between website accessibility and AI agent compatibility and how you can benefit from this connection.

You Ask, I Answer: How to Prepare Your Website for AI Agent Purchasing?
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, Paul asks, “How do we get ready for AI agents to buy from us?”
Now, remember, and I talked about this in a recent episode of the newsletter, an AI agent—really, you could just call it a self-driving app. It’s an app that runs itself. And AI agents can and will be acting as both buyers’ agents and sellers’ agents.
Think of it kind of like real estate. A vendor might have a seller’s agent that is available to talk to a buyer’s agent and say, “Hey, here’s the things we have on sale.” Imagine Siri or whoever on your phone has the ability to go on and shop on Amazon on your behalf. And you say, “Okay, Siri, here’s your list of things to buy. Here’s your budget. Go ahead and find me the best deals you can.”
And so that agent would go out onto Amazon and might talk to Amazon’s AI agent and say, “Hey, I’m here to negotiate.” Whether or not Amazon plays along is a separate question. That’s kind of the future state of where people see commerce with AI agents, particularly e-commerce.
How would you get ready for that? Well, here’s the thing. Agents are nothing more than apps. And apps can talk to websites today with things like JSON or APIs or webhooks or any of these technologies. But the agents are nothing more than apps.
The easiest way, the fastest way to get ready for AI agents that you can do today that will have up to a 10% increase in your revenue today is getting your website working with a screen reader. Making your website a first-class experience for screen readers, for people who have visual disabilities.
A screen reader is a piece of software that reads your website and then either reads it aloud or magnifies it. It does something to enable people with a visual disability to navigate sites better. If a screen reader today has no trouble getting to content, getting to your commerce funnel, and making a purchase for someone who is visually impaired, then an AI agent tomorrow will have no trouble doing the same thing.
If, on the other hand, your website is such a miserable experience for people with visual disabilities, an AI agent is not going to have a whole lot of extra luck. It’s not going to be—it doesn’t want to have magic powers to decode the tangled mess that is your website in a screen reader.
In the USA, we have ADA compliance—Americans with the Americans with Disabilities Act—that many companies should be following but aren’t. And there are a ton of tools that can do screen reader and visual disability compliance. IBM has a whole suite of accessibility tools that are all free that you can test your website with. Many other companies do as well.
You can also get a text web browser like links that runs on the command line in your computer, and you can fire it up and try and browse your website and just see how it goes. See how easy or difficult it is to purchase from you.
If you can’t purchase easily from a screen reader or text-based web browser today, an AI agent is going to have just as much trouble tomorrow. And it may buy the wrong things, it may cause all sorts of chaos. You can make a first-class experience for AI by making a first-class experience for the visually impaired.
And by the way, in doing so, even if AI agents never progress, even if AI agents are a pipe dream that never gets realized, that 10% of the population that is using assistive technologies to browse your website will be more likely to buy from you because they can because your website makes it easy. So even if AI was not a factor, you could add up to 10% more revenue by making your site easier to end more accessible.
So hopefully, Paul, that answers your question. Thanks for asking it. And I’ll talk to you on the next one.

In today’s episode, you’ll learn how to measure the ROI of AI even when the primary benefit is time savings. You’ll discover a simple yet effective method for converting time savings into a financial metric, allowing you to demonstrate the value of AI in a concrete way. I’ll walk you through a practical example and explain the importance of tracking your current ROI before evaluating the impact of AI. Tune in to gain valuable insights into measuring the true impact of AI on your business!
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, Michael asks, “How do you demonstrate the ROI of AI when you only have time savings?”
This is a really good question because we’re talking about—instead of return on investment, the standard financial formula—we’re almost talking about return on operations, return on essentially time savings.
Time savings is good, especially if you’re seeking increases in productivity—with the caveat, and this was something that folks mentioned on LinkedIn, that if you use the time poorly that you save, then there’s no benefit. If you save five hours a week on creating content and then you spend that five hours playing Candy Crush, you really haven’t done anything to increase the value of the time that you saved. However, if you were able to save that time and then do things that are equally or more profitable, then that time savings would have financial meaning.
So, here’s the basic formula for ROI. That’s a given. Earn minus spent divided by spent, that is ROI, that is return on investment—that is immutable, it is unchangeable, it is what it is.
If you were to do something that’s more like return on time savings or return on operational efficiency, it would look something like this: How much time did you spend on the task the old way of doing things? How much time do you spend on it the new way? And then use the same formula: new minus old divided by old will get you the percentage of time savings.
Now, here’s where you have to connect it to something of value. Assuming that you are productive, assuming that you are able to make the most of those time savings, then you would account for the time savings with your effective hourly rate.
Because there’s two forms of currency when it comes to ROI and return on efficiency. There is hard currency, which is where you give money to somebody else—you buy ads with it. And then there’s soft currency, which is opportunity cost. If you spend eight hours on a task, that’s eight hours you don’t have for another task.
So let’s say you earn, I don’t know, 50,000 a year or whatever, and you work 2,000 hours a year. If you do the math on that, your effective hourly rate is25 an hour. Now, if a task took 24 hours at that 25 an hour rate, that’d be600. If the same task took two hours using AI, at the same 25 an hour rate, that would be50. So your return on efficiency there would be 50 minus 600 divided by 600—new minus old divided by old. And that gets you a 92% return on the efficiency of the change.
That’s a gigantic number. Now, obviously, it makes sense if you spent essentially three working days on a task and you boil that down to a quarter of one day—that’s a big savings.
If you don’t have any other financial measures other than time—because time isn’t money, technically, time is money from a certain point of view—but if you have your effective hourly rate, based on your total compensation divided by the number of hours you work in a year, that can get you to a money number that you can then use for things like return on investment formulas.
So to answer Michael’s question, that’s how you demonstrate the ROI of AI when you only have time—you need to turn that time into money by multiplying it times your effective hourly rate, and then you can perform your standard ROI calculation: new minus old divided by old. When it’s new spend—time is money—minus old spend divided by old spend.
Is that the best way to value AI? Maybe, maybe not. Because it assumes that the work quality is the same, it makes a bunch of assumptions. And if your work quality improves while you’re using AI, then that formula would not capture that, it would only capture the time savings. Likewise, if you are driving real revenue, you would need to incorporate that revenue as well as your efficiency savings into the formula as well.
So there’s multiple angles that you can use to get at the ROI of AI with time savings. But you need to have the data first.
And as I said, in my newsletter a few weeks ago on the ROI of AI, if you don’t have the ROI of what you’re doing now, then calculating the ROI of AI makes no sense, because why bother? If you don’t know where you’re starting from, then you don’t know if things are better. If you never time yourself running the 100-meter dash and then you get new shoes, and you time yourself running the 100-meter dash, you’re like, “Yeah, I’ve improved.” How would you know if you didn’t time the original?
So if you’re not doing ROI computations today, on the way you’re doing things now, doing them for AI doesn’t make a whole lot of sense.

This week, let’s do a deep dive into AI agents. You’ve heard a lot about these recently from companies like Salesforce and Hubspot, all the things they can supposedly do, all the power they will allegedly unlock. How much of the talk is hype versus real, and how will you get started on your AI agent journey?
Part 1: What Is an AI Agent?
Let’s start with the bare basics. What is an agent? An agent is infrastructure around an AI model that lets the model communicate with the world around it.
Think of an AI model – like OpenAI o1 or GPT-4o, Google Gemini 1.5 Pro, Mistral Nemo, etc. – as the engine of a car. Incredibly powerful, comes in a bunch of sizes for different applications, very capable. Some engines you’re allowed to modify (open models), others not so much.
A model is the heart of AI. These things cost millions of dollars and hours to make, by training them on crazy amounts of data. But you never use a model directly. In the same way that Microsoft Word is a piece of software written by humans for human use, AI models are pieces of software written by AI for AI use.
We use models through an interface, something like ChatGPT or Claude or Poe, or within a service like Slack or Salesforce. These interfaces are essentially the rest of the car – the seats, the wheels, the windshield, the gas tank, etc. You never drive down the road sitting on an engine – you drive down the road in a car or truck.
And like a car, a consumer interface like ChatGPT does nothing without us to drive it. Open up ChatGPT and stare at the empty screen and it will not do anything. It won’t take action on its own, just as our Toyota Prius in the driveway doesn’t go anywhere without us getting in and turning it on.
Suppose we wanted our vehicle to do something on its own. We’d need a self-driving car or other autonomous vehicle, one that had instructions for what to do, one that could drive itself.
That’s what an agent is. It’s a different kind of infrastructure around an AI model, one that has greater autonomy to perform a specific task.
Think about an agent like a self-driving vehicle with a specific purpose. A commuter electric vehicle (EV) isn’t a pickup. A pickup isn’t a commercial tractor or plow. You wouldn’t drive a John Deere X9 1100 industrial combine to work (or you shouldn’t, anyway), nor should you plow a field with a Prius. The Prius engine might be able to do some light plowing, but the rest of the vehicle is unsuitable for that purpose.
In the same way, while an agent has a very powerful generative AI model at its heart, it still has clearly defined infrastructure around it that guides its purpose, and that infrastructure dictates what it should be used for.
What kind of infrastructure? An AI agent’s infrastructure looks a lot like any other app. There might be connectors to external data sources, talking to APIs upstream like your CRM. There’s likely code, middleware that performs specific tasks in sequence. That code will talk to an AI model of some kind, and then when results come back from the AI model, there will be more code to send the results somewhere else. Finally, there will be some kind of scheduler or triggering mechanism that will tell the agent to do its thing.
I’ll give you an example of an AI agent I built. I built an agent to score blog posts. The agent’s components are:
A Python script to grab URLs from an RSS feed and extract the main page content, storing it in a SQLite database
An R script that talks to the SQLite database, feeds each blog post, one at a time, into a language model along with the Trust Insights Ideal Customer Profile
The same script takes the scores returned by the language model, stores them back in the database, and then makes a bar graph of the scores over time
This agent is manually triggered, but once it was written, it’s something that can just run and do its thing without my intervention. It can’t do anything else EXCEPT this task, but it does this task well.
If this sounds like an app, it is. “AI Agent” is just fancy, expensive language for a self-driving app.
Part 2: Why Do We Care About AI Agents?
The reality is that consumer tools like ChatGPT scale poorly. You can, and should, have things like prompt libraries where you can share and improve prompts, but ChatGPT still requires a human to operate it.
What if you wanted to take a high performing prompt, like writing a monthly report, and have a machine do that task autonomously? Instead of you having to download the data, clean the data, pass it to an AI model, and copy paste the results into an output format, you’d have an agent perform that sequence of repetitive, predictable tasks instead.
Agents are a natural evolution of the most repetitive generative AI tasks, where you have clearly defined processes and outcomes that are as predictable as the sun coming up or the phases of the moon.
That part, the repetitive part, is critical. Agents are best suited for repetitive tasks with predictable outcomes, where minimal human supervision is needed. Language models give us far more flexibility than traditional agents – anyone who’s ever used old-school chatbots on websites know how little flexibility the past generation had – but are still best suited for tasks with clear outcomes. It’s a poor use case for an open ended chatbot, for example, to run on your website where people can have conversations about anything. (Not to mention expensive)
How do you know what’s a great task for an agent? Here’s a simple benchmark. If you use generative AI in a system like ChatGPT and you’re just copy pasting prompts and copy pasting outputs with very little thinking or review needed, you’ve got a task that’s ideally suited for an agent.
That SWOT analysis you run quarterly where you just copy paste data, upload files, copy paste the prompt, and then copy paste the results into a slide deck? That’s 100% an agent task that can and should run autonomously. The final product should just appear in your inbox.
The example earlier of scoring blog posts? Doing that one at a time, copy pasting the post in, and copy pasting the results out? Giant waste of time for a person to do that. Having AI do that with the help of code around it? Perfect use case to unlock the power of AI at scale.
A lot of people think AI Agents are just chatbots, in the same way they think of ChatGPT as just a blog post writing tool. Yes, they can do that. But using it just for that purpose is like taking a Harrier to the grocery store. It can do that, but it’s capable of so much more.
What are some common AI agent use cases? It depends on the industry. In marketing, these can be things like shopping assistants, price optimization, consumer-facing chatbots, customer service, etc. Here’s the easy rule of thumb: if it’s a valuable prompt today, it’s an agent tomorrow. Someone will wire up the necessary infrastructure to turn that high-performing prompt into a self-driving app.
Part 3: What Does the Agent Ecosystem Look Like?
As we’ve seen and heard at major conferences and trade shows this fall, everyone and their cousin is rolling out a low-code/no-code agent framework. Salesforce has AgentForce. Hubspot has Agent.ai. There are dedicated platforms like Poe, Character.ai, etc. that are low-code or no code.
There are advanced, heavy-code platforms like Google Vertex. And in the various marketing technology landscapes, there are hundreds more agent vendors. All of them promise the same thing – powerful, easy to build, easy to deploy agents. Many of the no-code ecosystems offer pre-build agents that you can simply pick up and use, in the same way that you use any SaaS service.
All of the SaaS agent platforms have the same purpose: to get you to buy (or stay) with their platforms by fully automating agent creation and management. In some ways, it’s another form of vendor lock-in – everyone wants you to build agents in their ecosystem, on their platform, so that it’s harder to leave.
Here’s the thing: remember that AI agents are nothing more than self-driving apps. That means that like AI models themselves, you can build agents entirely within your own ecosystem and infrastructure. If there’s a use case for generative AI that you feel is valuable enough to turn into an agent, then there’s good reason to consider building that agent in house as opposed to having it live in a third party’s ecosystem.
How do you decide whether to buy or build? It comes down to whether or not you have the people, skills, and infrastructure to support the agent or not. Again, they’re just apps. If you already self-host apps at your company, then you can just as easily self-host AI agents.
Part 4: How Do You Build an AI Agent?
You’re probably at least 50% of the way towards your first agent. Let’s go through the evolution of an agent. We start with basic generative AI, with prompts in tools like Claude and ChatGPT. You use these tools with prompts. This is old hat by now.
Over time, you should be systematizing your use of prompts, with things like prompt libraries. These are stock prompts you’ve built that create high-performance outcomes, and these prompt libraries are things you share with your team at your company. For example, at Trust Insights, we have a ton of shared prompts in our Google Drive that we can just drop right into Gemini whenever we need to. And because they’re nothing more than Google Docs, anyone can edit them, upgrade them, etc.
After your prompt library, you might get to a point where you want to turn your prompts into hosted apps, using custom GPTs (ChatGPT), Gems (Gemini), or artifacts (Claude). These apps are sophisticated prompts and background information that are designed for a specific task like writing Google Ads or analyzing competitive corporate strategy. They’re tuned for that specific purpose. They’re not self-driving – a person still has to operate a Gem, a GPT, or an artifact, but they’re very close to an agent. A user who picks up one of these apps doesn’t have to do any prompting, they can just get right to work.
It’s at this point where you would convert the Gem/GPT/artifact into an agent. Instead of you, the human, using the app, you might convert the app into an agent that can retrieve the appropriate data, pass it through a generative AI model, and then send the outputs somewhere for other use.
How do you do this? It’s at this point where you would decide to use a third party platform or build it yourself. The best way to make that determination is to use the Trust Insights 5P Framework; we should define the purpose, people, process, platform, and performance of our agent and how it evolves.
First, the purpose: what is the AI agent supposed to do? What outcome should it generate, what problem should it solve? If you’re extending the work you’ve already done with GPTs/Gems/Artifacts, then you should have a pretty clear idea of what this is. If you’re starting from scratch, take the time to write out some user stories and do requirements gathering – the same as you would for building any kind of app.
Second, once you have a robust list of requirements, take a look at your people. Who will be using this agent? Just internal employees? The general public? That’s important to know. Equally important is to determine what skills your agent needs. If you’ve identified that the agent will need serious coding, do you have those skills in-house? If not, then you’ll almost certainly need to use a third party platform.
Third, it’s time to look at your current processes, your current prompts and AI. Do you have specific requirements you need to meet, standards for compliance, data privacy, etc.? The same standards you use for regular, human-driven generative AI will apply to your agent, so if you have to use AI solutions with a certain level of data privacy, that will in turn help you choose your AI agent strategy. You can’t reasonably put an agent on a hosted service that doesn’t meet the same standards as the models themselves.
Once you’ve done these steps, then you can start evaluating what platform you want your agent to live on. As with all AI, remember that choosing the technology and platform comes last, after you’ve worked out the requirements for everything else.
Finally, decide how you’ll measure the performance of your agent. At a fundamental level, it obviously has to work. Additional KPIs will be determined by your purpose; if your goal is to serve X number of customers, then you can measure that and determine if that’s working as intended. If privacy is a critical concern, then you measure how much data is leaking in your ecosystem. If marketing is your purpose, then you measure marketing activity like how quickly customers are advancing through the customer journey. Whatever your purpose is, measure it.
In the video edition, I walk through the building of a simple agent based on my language translation system instructions.
Wrapping Up
AI agents are a natural evolution of our generative AI use cases. If we’re already getting benefit from our human-driven AI usage, getting benefit from our agents is the next logical step in the process.
I would add that for minimum frustration and maximum value, you don’t want to skip straight to building an agent most of the time. Instead, think about using tools like Claude, Gemini, and ChatGPT essentially as R&D tools to develop the use case for an agent, prove the concept, iron out the bugs in your prompting, and only then build it into an agent. You’ll save yourself a tremendous amount of time and headache that way.

Fireside Chat: Music and AI, Part 5: Hungry Eyes on Charing Cross: AI Composition in Action
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
Christopher S. Penn – 00:00
In this five-part series on music and AI, filmed at the 2024 Marketing AI Conference, or MACON in Cleveland, I sit down with composer Ruby King to discuss AI music and the future of creativity. This is part five, the fifth and final part of the song Hungry Eyes on Charing — AI composition in action. That is not at all a chamber —
Ruby King – 00:25
— see what it does in here. See if it changes to altos.
Christopher S. Penn – 00:41
Nope.
Ruby King – 00:45
Not different modes? No. That is a fail.
Christopher S. Penn – 00:49
Yes.
Ruby King – 00:49
If I submitted that, I would be — nope.
Christopher S. Penn – 00:53
Alright, let’s see what variation two of that particular one — who managed to nail it or not? Nope. Immediately.
Ruby King – 01:00
I mean, it’s epic, but it’s —
Christopher S. Penn – 01:02
— it’s epic, but that’s not a chamber —
Ruby King – 01:03
— this is a hungry cat in London. That’s a bit OTT, don’t you think? I mean, ignoring the instructions — soprano one and two, that’s —
Christopher S. Penn – 01:24
— yeah.
Ruby King – 01:25
— and with all the nice — so many times aren’t quite — women of their church, might be. Tenors — it’s hard. Okay. It’s got a separate line of harmony held with no words. Oh, that was interesting. Clipping. The last note of that is a weird one.
Christopher S. Penn – 03:22
Which line are we on? So it has mangled the lyrics. It is no longer following the lyrics.
Ruby King – 03:48
It did follow word painting of that bit. I’m not sure what it’s singing now. I’ve not — oh. Oh, there’s more.
Christopher S. Penn – 04:04
So it has gone back and repeated — is now repeating tenor one and two, which it shouldn’t be.
Ruby King – 04:11
No, it wants to.
Christopher S. Penn – 04:13
It wants to.
Ruby King – 04:13
Who are we to kill creativity?
Christopher S. Penn – 04:15
Let’s see what the second variation is. Any better?
Ruby King – 04:18
Okay.
Christopher S. Penn – 04:18
Nope.
Ruby King – 04:19
Nope. That’s a hard pass.
Christopher S. Penn – 04:22
So out of four variations, it didn’t even get the genre right for three of them.
Ruby King – 04:27
That’s a tricky thing. Also, it completely ignored when it was told brass and baby — pardon? Bass and soprano, and it had its own ideas.
Christopher S. Penn – 04:38
Yes. So obviously, it still has a bit of a ways to go, but that’s the process for building that. And with a tool like Suno, you have to do a bunch of candidates so that it eventually gets one of them right. But, to your point earlier, it’s — you would not have — you would not have paid a musician to make that song.
Ruby King – 05:02
People frequently do.
Christopher S. Penn – 05:03
Really?
Ruby King – 05:04
They do. Yeah. So there’s a lady who came to our university not too long ago. I first saw her because I went to a Royal Albert Hall performance in London, and that was sort of music for royal occasions because it was around the time of big royal occasions, and we thought it’d be great to hear that kind of thing in a big hall. Yeah, it was a lot of very famous music, Zadok the Priest, which is quite an important, famous one. So I went, and one of her pieces — one of the pieces there — was commissioned especially for the occasion. It had never been heard before, and it was the first time we heard it. And I got to meet the composer afterwards, very briefly. I think she signed something, and I ran away all giddy.
Ruby King – 05:51
Then she came to the university afterwards, and she recognized me. Yay. But she had been — I believe she’d been commissioned to write a piece for a chamber choir that was at a church because there are still — when you go to churches, especially in England — I cannot speak of America. I have been here for five minutes. I don’t know what’s going on. But in England, there are old-style churches that still have chamber choirs that still dress in the red and white, with the little frilly stuff — they’re cool, don’t dis it — and they still sing.
Ruby King – 06:26
There are still sometimes gender requirements for — not always, but sometimes there are still, I think — yeah, but they need music, and it’s fine singing the old stuff. But sometimes you want to commission a new piece for a special occasion. Maybe it’s the birthday — 500th birthday of something — and you want to have a special thing. They can be commissioned. They are commissioned, but it depends on what it’s for and how much money there is, whether they even hire you to sing it, let alone if you told this to write that for you. Can it give you the score, the sheet music, to give to your musicians? Because, at the moment, I think the answer is no to that.
Christopher S. Penn – 07:07
The answer is this tool cannot. You can use other tools to decompile it.
Ruby King – 07:11
Okay. I’m not sure how effective that would be, bearing in mind some of those notes were kind of — I know this is meant to be loud with a lot of notes, and there’s some notes in here — don’t listen to all of them.
Christopher S. Penn – 07:21
No, I meant it’s unlikely someone would write a — commission a song about a hungry cat just for fun.
Ruby King – 07:29
There have been stranger things.
Christopher S. Penn – 07:31
Fair enough. Okay. But yeah, that’s the process for how you would use generative AI. Today, it’s not something you can do all in one tool that’s going to be highly effective. It’s going to be something you have to do across multiple tools that will change over time, as well as the audio models themselves will get better over time. Thanks. So I guess that leaves us at the end of this to say, what do you think about the future of music, given what we worked on, what you know of the industry, and what you know of the way AI is going?
Ruby King – 08:06
I think it’s going to change. I know that a lot of people are concerned and hoping for the best that — I think it’s a tricky situation because a lot of it does come down to laws and people in other countries a long way away from most of the people I know in the industry and what they decide. It also depends a very large amount on the morals and ethics and beliefs and preferences of the people who have the money to usually commission that music. The music industry has already changed so much because of streaming. I mean, back in the day — a very, very long time ago — you would live in the residence of someone who would pay you to write the music. And then a patron. Yeah, exactly. It’s not like that anymore.
Ruby King – 09:02
Back in my day, not quite, but that was the way it was, and now that’s nearly unthinkable. I can’t think off the top of my head of anyone who’s in that particularly great situation. But streaming has changed it, and streaming pays so little that it’s a real problem, and it can’t continue forever. But where that line is — where it changes — is it going to change in favor of musicians and giving us a fair cut of what our work is worth, or is it going to change? “We didn’t need you anyway. AI will now be what we have, and we will invest all our money in improving AI rather than paying you enough money to incentivize you to write good music.” Because we’re not — musicians, composers have to do a lot of work to get our music — their music heard, and that will no longer be anything but a hobby if the money from Spotify and stuff is sent over to preference of AI and trying to get that to be the best that it can be so that more people go, “Okay, that was the old times. This is the new times. You have to be up and with it, with the new times. Goodbye humans, hello machines.”
It all does depend on so many different things. I think it’s impossible to say right now what is going to happen. Anyone who is predicting the future — which is a bad — don’t do that. Doesn’t work.
Christopher S. Penn – 10:31
I would agree, with the caveat that some — this is, as a psychology person — some human behaviors are very predictable. Greed and stupidity are highly predictable. People generally want better, faster, and cheaper. That’s highly predictable. People want to be entertained and engaged, and to some degree, educated. With that backdrop, given how the industry of music functions, it is highly probable that at least in the short term, there will be — music industries will see — music companies will say, “We can save a lot of money by not paying humans and generate music that people will find acceptable enough.”
Ruby King – 11:15
Which is why it also depends on laws and rules. I’m not sure what happened with — something that — there was such a lawsuit where Open — it was OpenAI — said, “We can’t do what we do without this content.” Are they being told they can’t?
Christopher S. Penn – 11:31
Well, those court cases are going to take years to work out, so it is unclear.
Ruby King – 11:37
Okay. Well, that could help musicians in the future. It could. And if that cloud is over the heads of tech companies, then investing every single penny into making it as great as possible might be slowed down because if it isn’t — if there’s a possibility that all that money is wasted — then greed dictates that money being wasted is bad.
Christopher S. Penn – 11:58
Right. So, for those independent companies, that’s true. What is probable is that it will hyper-concentrate into the tech companies that have the legal standing — Google and Meta — as the company’s, “Hey, you’re using Instagram and Facebook and YouTube. You gave us licenses. So here’s our models that are now the best-in-class models because we have the legal standing to say, ‘You told us we can make derivative work. So here’s your stuff.’”
Ruby King – 12:24
Yes. Yeah. Well, with greed, the music industry has got so much greed in it already. It’s infested. It’s really a difficult thing to get into, especially for minorities or anyone, but the usual, which I don’t have to explain. So it’s hard enough as it is, and then you add in all these other things, and it’s — things are only going to get worse. I would like to say until they get better, but I’m not sure you can predict that either.
Christopher S. Penn – 12:59
No, we cannot.
Ruby King – 13:00
No.
Christopher S. Penn – 13:01
No. Alright, well, thank you. I appreciate your time for this series. We’re going to publish this as a series because no one’s going to sit through 90 minutes of this. And thank you very much. Alright, we’re done. That concludes our series. I hope you found it helpful and useful, and we’d love your feedback about your thoughts on AI music, the ethics of using AI, and so on and so forth.

Fireside Chat: Music and AI, Part 4: Teaching AI to Write Lyrics: Deep Dive into Chamber Choir Music
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
Christopher S. Penn – 00:01
In this five-part series on music and AI, filmed at the 2024 Marketing AI Conference, I sit down with composer Ruby King to discuss AI music and the future of creativity. This is part four, teaching AI to write lyrics — a deep dive into chamber choir music. Okay, so let’s do this. Let’s transition here. I’m going to go ahead and share my screen, and we’re going to see how well — yay, infinity tunnel — let’s go here to Bard first, and then AI Studio. So I’m going to use Google’s AI Studio, and the first thing I want to do is I want to get an understanding of what constitutes good songwriting. So I’m going to ask you to evaluate the model’s thing. So your topic is best practices for — what genre of music do you know very well that has lyrics? Pop, rock —
Christopher S. Penn – 00:58
— I guess it’s more grunge.
Ruby King – 01:00
No, no, it’s more — it’s classical pieces that have lyrics.
Christopher S. Penn – 01:08
I mean, Gregorian chants.
Ruby King – 01:11
No, chamber choir music or something like that, where there’s four parts or that kind of thing. I can do that.
Christopher S. Penn – 01:18
Lyrics to chamber choir pieces. So that is what we’re going to go for. We’re going to choose the Gemini model. We’re going to choose an output length of 16,384 tokens.
Ruby King – 01:32
Does it have to be with words for this one?
Christopher S. Penn – 01:34
Because you’re looking at — well, we wanted to do stuff with lyrics, and the reason we want to do it with lyrics is specifically because, for tools like Suno in particular, part of the generation is the lyrics themselves. That’s part of the prompt. So let’s see what Gemini has to say: “Best practices for generating lyrics for chamber choir pieces. Understanding the vocal capabilities and limitations of a chamber choir. Voice types and ranges. Blending and balance. Ensemble size and dynamics. Text selection. Text — choosing appropriate texts. Considerations for length, subject matter. Word painting and musical expression.”
Ruby King – 02:18
Example, word painting. That’s good.
Christopher S. Penn – 02:20
Okay. “Syllabic versus melismatic setting.”
Ruby King – 02:24
Yeah. Melismatic is when there was that singing before where it had no words.
Christopher S. Penn – 02:29
Okay, got it.
Ruby King – 02:31
AI doesn’t do that terribly well, but it’s singing multiple notes to a sound.
Christopher S. Penn – 02:35
Okay. “Creating unified, engaging musical structure, form, and development. Strophic through composed ABA. Vocal lines and harmony, repetition and variation. Practical considerations of performance. Score clarity and readability. Accessibility and singability. Common mistakes of less experienced practitioners. Writing ranges that are too wide or uncomfortable.”
Ruby King – 02:53
Yep, absolutely.
Christopher S. Penn – 02:55
“Neglecting vocal blended balance.”
Ruby King – 02:59
Can be a choice, but yeah.
Christopher S. Penn – 03:01
Okay. “Overlooking dynamics on ensemble size. Choosing texts that are unsuitable for choral music.”
Ruby King – 03:07
Yeah.
Christopher S. Penn – 03:08
“Overusing or misusing word painting. Inconsistent or inappropriate syllabic choices. Lack of musical structure development. Weak or unclear form. Uninstrung or unbalanced vocal lines. Neglecting practical considerations. Chamber choirs can — we sing quiet, introspective music that is generally to be true, but is actually false.” Really? “Rhyming lyrics are essential for chamber music.” Over there.
Ruby King – 03:34
I wouldn’t say so. A lot of the time, we’re singing just words straight from the Bible.
Christopher S. Penn – 03:38
Right. So they’re saying these are things that people believe to be true but are actually false.
Ruby King – 03:42
Okay. Yes, that’s true.
Christopher S. Penn – 03:43
“Latin texts are always more appropriate.”
Ruby King – 03:46
Yeah.
Christopher S. Penn – 03:47
Okay. “Things that are believed to be false but are actually true. Simple text can inspire profound choral music. Silence can be a powerful element. Collaborating with a living poet can enrich the creative process. Tips and tricks. Listen deeply to singers. Sing the parts yourselves. Study a choral score.” So these are all things you would say are appropriate for what you should know to create good chamber music.
Ruby King – 04:13
Yeah, I mean, I’ve not seen anything I disagree with.
Christopher S. Penn – 04:16
Okay. Is there anything missing that you know of that it didn’t know?
Ruby King – 04:23
Did it speak about the spaces that things are being sung in? I didn’t see that there. But it does also — if you’re singing in a really big church, you might choose — the amount of singers might be different with how many parts you split into.
Christopher S. Penn – 04:37
No, because we specified writing lyrics.
Ruby King – 04:41
Yes. Yeah. Okay. Yes. Lyrics also matter here, though, because if you’ve got — chamber choir is four parts, usually. So if you’ve got — if you’re writing lyrics and you’re in different spaces, you might want to write more words in a shorter period of time with lots of people doing different words. If you don’t care — what if — if you’re in a church service, usually when you’re hearing chamber choir, you want to hear the words that are being said because it is about worship, and that is the idea. If it’s a concert of chamber choir music for a different purpose, then you might have lots of different interweaving lines. But when it was for church services, I’d mostly have everyone singing the same word at the same time, but different notes.
Ruby King – 05:30
So it was nice to hear, but a few passing notes in emphasizing words, but it does change with the purpose of the service or the purpose of the music.
Christopher S. Penn – 05:42
Okay, so next, let’s have it create a scoring rubric. So next, create a scoring rubric that can evaluate a set of chamber choir lyrics and how well they adhere to our best practices and tips and tricks so far. The individual items in the scoring rubric should be scored as variable integers: zero to three, zero to five, zero to seven, etc. The rubric — hide that because I can’t see what I’m doing. There we go. The rubric as a whole should total 100 points. The purpose is to give lyrics an assessment of how well they conform to best practices. So let’s see what the model comes up with. So it’s going to say, “Here is how to score a set of lyrics.”
Ruby King – 06:55
Oh boy, okay. Just letting you know, this — again.
Christopher S. Penn – 07:05
Well, this is — this scoring rubric is one of the magic terms in generative AI, where you’re saying to the model, “I want you to evaluate.” And instead of saying, “Model, is this good or bad?” — because the model doesn’t know — you give it a set of scores that then it can use as a baseline. Say, “Here’s how — what I think I understand about this.” So let’s save this. This is our Gemini chamber choir lyrics gem rubric. Okay, so we’ve got our rubric now. Now let’s have it generate some lyrics, some chamber choir lyrics. What topic should we use?
Ruby King – 07:57
Usually, it’s sacred.
Christopher S. Penn – 07:58
Okay, let’s not offend anyone.
Ruby King – 08:00
Okay.
Christopher S. Penn – 08:04
Remember, this is a generative AI model, so it can make anything about anything.
Ruby King – 08:09
Okay. Chamber choirs are usually used for slow, solemn things. So if we do — usually, it’s quite effective if it’s sad or crying. So it just — you can have more upbeat ones, but usually, that’s all right.
Christopher S. Penn – 08:27
So let’s do this. Alright, next, generate two candidate sets of lyrics. The overall topic for the song should be a cat that is prowling around the streets of London, hungry. The lyrics should reflect this general situation and tell a story. Generate two candidate sets of chamber choir lyrics for this story. London’s tomcat prowl. Soprano one, alto one.
Ruby King – 09:16
Did it just start the word with “sh”? How are you meant to sing “sh”? I mean — okay, some of the time it does just write that, and then you make the sound, but we had music, though. We literally had to all go “quack” at the same time with notes. That’s just what happens, but it’s not a strong start.
Christopher S. Penn – 09:37
Okay, so we have candidate one, London tomcat prowl.
Ruby King – 09:43
Oh, they’ve got it in different — are they split into — okay. Soprano one and two. Okay, so split the sopranos and altos and tenors and basses into one and two. Okay, that’s alright.
Christopher S. Penn – 09:55
Okay, now score each candidate according to our rubric.
Ruby King – 10:05
“I did great. Thanks for asking.” Oh, it’s quite mean.
Christopher S. Penn – 10:23
So the first candidate scored 79 out of 100. The second one scored 82 out of 100. Great. Make a refinement of candidate two that improves the overall score. Create the candidate refinement and score it. So what we’re doing here — this is a three-part process that we use for generative AI when we’re doing anything commercially with generation, which is create, score, refine.
One of the things people do the most wrong with generative AI is to say, “Just do the thing,” and they accept the output — “Build!” — and they’re, “Oh, it kind of sucks. Generative is not very creative.” Well, no, you failed to prime the model. You failed to understand the context, and then you gave it a prompt that was stupid and insufficient. And so what we’re doing here is we’re basically telling the model, “You need to keep improving until you get it right.”
Ruby King – 11:33
That’s what my math teacher used to say: “Rubbish in, rubbish out,” too.
Christopher S. Penn – 11:37
So here’s candidate two refinement. Hungry eyes on Charing Cross. You can see it’s revised for better sound, revised for a smooth line, and so on and so forth. And so this refinement, it now scores an 88.
Ruby King – 11:50
Okay. Make it even better.
Christopher S. Penn – 11:54
Yes, essentially. See? Great. Take the refinement and improve it until it — improve it so that it scores better. So this is candidate set to refinement two, revised for alliteration and imagery, revised for more specific imagery, stronger association, stronger metaphorical language.
Ruby King – 12:24
Oh, it’s scoring a lot better now.
Christopher S. Penn – 12:26
Mm-hmm. And it tells you the justification.
Ruby King – 12:30
Hold on. I got eight out of seven there. That’s cheating.
Christopher S. Penn – 12:34
That is cheating. So it scored a 90. Now, the next thing we want to do — so every — almost every model that’s made out there, like Suno’s, has at some point, probably used a generative language model as its foundation. So what is — what are the characteristics? How would you tell someone else to compose a piece of chamber music?
Ruby King – 13:05
That’s very difficult. You mean lyric specifically?
Christopher S. Penn – 13:09
No, no, the music, the music itself. What would be the musicality? I’m going to save this — the lyrics themselves. I’m going to — great. Show me the final version of the refined lyrics without any of the notes for improvements. So what we want is just the clean lyrics. Okay, so we have our final lyrics here. That’s our song title, Hungry Eyes on Charing Cross. How would you give instructions to a composer to write the music that goes —
Ruby King – 13:58
— with this word painting? Okay, bearing in mind, what have we got? Beneath the gaslight amber gleam — the lines look about equal. So probably write a melody that aligns with the word painting of the idea of the piece because if it’s going to be repeated, they can’t work for every single line necessarily. Use that in the way it’s written in. It might just be an AAA structure here. It’s hard to tell because it’s just doing different sections.
Christopher S. Penn – 14:49
Okay, let’s ask it. See what it — what do you know about composing the musical to accompany these lyrics? Emotive, atmospheric, quiet introduction. Tenors and basses, soprano, alto, tenor, all voices. Is there instrumentation in chamber choir music? Is it all human singing only?
Ruby King – 15:08
There can be, but chamber choirs usually don’t have it because there’s so many different parts, and all the voices kind of work together. It’s a bit more like a string quartet. You can have other instruments with a string quartet, but the string quartet is, of its own, a string quartet that is capable of doing pieces of its own.
Christopher S. Penn – 15:23
Got it. Okay. What instructions would you give a composer to generate the music for this? Focus on technical specifics like tempo and key. So we’re going to essentially ask the model to distill down the instructions that it would give to a composer because when we get to the Suno portion, we want to feed it very specific instructions that hopefully will evoke the correct tokens in its memory to pull together its knowledge. The challenge is Suno’s prompting structure is intentionally very short so that you can’t give it highly specific instructions to replicate copyrighted music. So it has to be distilled down. So great. Distill down these instructions to 200 characters of text. Omit verbs.
Ruby King – 16:33
London night is not an instruction.
Christopher S. Penn – 16:35
Yes.
Ruby King – 16:36
Minor key is — tempo shift. Good word painting. Yes. Dynamics? Pianissimo, mezzo forte, fortissimo. No. Okay.
Christopher S. Penn – 16:45
Eliminate references to the content, such as London Night, so that our 200 characters of instructions are devoted to the music composition.
Ruby King – 17:03
Also, why does it want an unresolved ending?
Christopher S. Penn – 17:06
I don’t know. It seems to think that’s important. So that’s the unresolved question. Consider cello or piano optional.
Ruby King – 17:15
No, no, we’re not doing that here. Nice try.
Christopher S. Penn – 17:18
Okay, so let’s copy this into seven structures. We’re going to remove that because we’ve decided that’s not going to be something we do.
Ruby King – 17:25
It’s actually written out pianissimo, fortissimo this time.
Christopher S. Penn – 17:27
Yes, because we gave it more room. So this is 255 characters. So we might have to —
Ruby King – 17:34
— as long as Suno will — you do — Suno understands?
Christopher S. Penn – 17:38
Yeah. So we’re down to 227. Very texture. Let’s get rid of the unresolved ending. Now we’re at 201. Minor key.
Christopher S. Penn – 17:53
Yeah, it’s right down here. So we’re at 187. So now let’s go into create mode. We’re going to do custom. We have — oh, it’s — sorry. It’s 120 characters.
Ruby King – 18:09
Okay. To be fair, the dynamic range doesn’t need to say that because that is — as quiet as you can go to as loud as you can get, pretty much. So just full dynamic range.
Christopher S. Penn – 18:17
So what if we do word painting? So you said full — just full dynamic range.
Ruby King – 18:21
It is, maybe, yeah.
Christopher S. Penn – 18:22
Okay, so we’re at 107 characters. Let’s do homophonic, polyphonic. That’s 151 standard chamber. Actually, just probably just chamber choir, right?
Ruby King – 18:38
Yeah, we’ll see what it does if it needs —
Christopher S. Penn – 18:41
— okay. Anything else that we could remove there other than that comma? We’re seven characters over still.
Ruby King – 18:57
When it has the dashes, is that saying, “Do it this, then this, then this”?
Christopher S. Penn – 19:01
Not necessarily. That’s just how it spit it out.
Ruby King – 19:03
Okay, then take out andante.
Christopher S. Penn – 19:09
Take out andante. Okay, so now we’re at 119, which is perfect. So let’s go ahead and take our — that’s going to be our song title. We’re going to put that down here as candidate one. Our lyrics — we’re going to get rid of the bolding. We don’t need it. Cut that into here.
Ruby King – 19:33
I can tell you’ve done this a lot of times before.
Christopher S. Penn – 19:35
Yes. And then we’re going to take our instructions for style of music, 119. Just to be on the safe side, I’m going to move chamber choir to the top of the instructions.
Ruby King – 19:46
Okay. I don’t want to rope a piece that is, “This cat is hungry.”
Christopher S. Penn – 19:51
And we’re going to create variant one. Is there anything that you would change?
Ruby King – 20:00
What, at this stage?
Christopher S. Penn – 20:01
At this stage, in terms of the musical instructions.
Ruby King – 20:08
Close, dissonant harmonies. It depends when it uses it. I think that’s a difficult one because dissonant harmonies do work as long as they’re resolved. If they’re not resolved — if it just closes, dissonant harmonies, then you don’t want to listen to it. I mean, dissonance is an interesting thing to use, but it’s only satisfying if it resolves.
Christopher S. Penn – 20:28
Okay. I pulled out homophonic, just went with polyphonic. So I did a second variation with that. Let’s see what it’s come up with for our variations. Are you ready?
Ruby King – 20:37
Yeah. Alright, I’m ready.

We’ll also discuss the future of musicians in a world where AI can generate music on demand, exploring potential career paths and the enduring value of human artistry. Tune in for a thought-provoking conversation on the ethical considerations and future implications of AI-generated music.
Fireside Chat: Music and AI, Part 3: The Ethics of AI Music: Consent and the Future of Musicians
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
Christopher S. Penn – 00:01
In this five-part series on music and AI, filmed at the 2024 Marketing AI Conference, or MACON, I sit down with composer Ruby King to discuss AI music and the future of creativity. This is part three, the ethics of AI music, consent, and the future of musicians. So, based on what you’ve heard, what would be, to you, the use cases for using this type of output? I imagine things like, for example, hold music.
Ruby King – 00:30
The quality of phone lines — is anyone going to be able to actually hear it properly? Exactly. I mean, we have Vivaldi Spring on our hospital line, and that’s so crackly that it may as well just be a rat playing it. Yes. So wait things — that does work for the quiet backgrounds of music, videos, too. But it does depend how lively it is because that is quite lively, and it’s got quite a strong feel to it. You kind of want to move to it a little bit. So if you’re doing a talk and that is playing, then obviously no. But that’s the same if you had a piece that’s performed, and you’ve got the rights for it to have it there, you’ve still got to choose your music wisely. That doesn’t change whether it’s AI or not.
Ruby King – 01:24
That performance sounded like a good, well-recorded piano, and it sounded at least 99% possible to play, I believe. It is hard to tell listening like that, but there was none of it where I was thinking, “Okay, these hands are not happening.” You’ve seen those things where you can make the piano sound like a voice, but you can’t do it with your fingers because it uses too many frequencies all at the same time to make it sound like it’s saying —
Christopher S. Penn – 02:06
— you need 14 fingers on each hand.
Ruby King – 02:08
More. Yeah. There is a wide variety of use cases, as much as I hate to say it.
Christopher S. Penn – 02:17
Okay, so talk about that.
Ruby King – 02:18
Yeah. Okay. Why I hate to say it?
Christopher S. Penn – 02:22
Yes. Because there’s sort of this push and pull of the AI side of things, saying, “Hey, this is a great substitute,” say, for royalty-free music, where you get your stock — whatever — download of your 200,000 songs, all of which are pretty much that. Or you can have something that’s custom-made by a machine that is equally — but you don’t have to pay $49.95 for it.
Ruby King – 02:53
Yeah. Okay. I suppose it comes down to two things. One of those is morals. So I mean, you can try and —
Christopher S. Penn – 03:01
— ignore morals, but many people do.
Ruby King – 03:04
Yeah. So when it’s royalty-free music or something, then someone has given their consent for it to be that, usually. I think it’s — if you’re buying the pack, then somewhere along the lines, the musician got money. They went, “I’ve written this piece. Do you want it?” They went, “Yes, we want it. You either have no royalties to it,” or whatever the signage is, depending on where it is, I guess. “Can we have it?” “Yes, you can. Here’s some money.” Probably not enough, but okay, deal done. That is given with consent.
When it comes down to AI, there is not much consent around here, and people seem to have a very decent understanding of when consent is involved with things of a nature that is not necessarily IP and might be more related to humans. And while it may not seem as bad — non-consensual anything else — when you are using AI to write music, it’s still without consent. You are using other people’s work, effort, and time without their consent in order to write something for yourself when you could have paid them either nothing — they might have given it to you for free — or a very small pittance. Musicians don’t make a lot. There is — you could get it for a little bit of money and sleep better at night, maybe.
Christopher S. Penn – 04:33
Okay.
Ruby King – 04:34
But in the way of, “Is it actually better to have a musician do it for the end product?” More and more, the answer is becoming it’s not that important because it is improving. I would say right now, it’s not perfect enough for musicians to be completely ruled out because there are issues with it. When you are listening to it, depending on the level of your training or the amount you care, it’s not right. There are issues with it. But if you really don’t care, and it’s for something that you’re not willing to pay any money for, and you’re, “I can just generate this. Why would I pay anyone for it?” Well, yeah, sure, okay. If you don’t care, then it works.
It does the job that you want it to do, and it does that very well in a lot of cases. I have listened to some Bach or Mozart that’s AI-generated. So it’s not actually them, but it’s told to — yeah, exactly. And it sounds fairly convincing. It sounds like it might actually be an orchestra playing it.
Christopher S. Penn – 05:42
Right.
Ruby King – 05:44
But there’s no real melody to it, and it’s kind of — it’s not quite right. But if you’re doing — if you’re studying and you’re listening to that at the same time, for the sake of not having something that you know and are singing along with in your head, then it works. It does the job. A lot of AI is increasingly going to just do the job, and it is a concern for musicians and composers that it is just improving and improving. It’s using our work without our consent to do so and thus taking away quite a lot of the importance of teaching music, which is already at the bottom of the barrel in quite a lot of countries, including England.
It should be more important. But if the tech industry keeps doing this, then the tech industry will become more important, music will be less important, and then we have a — this is a whole different topic. I’m really sorry.
Christopher S. Penn – 06:39
Well, the consent thing is important because, yes, companies — Suno and Mubert — allegedly, because this is in court, you have to say allegedly, otherwise lawyers come out — did ingest large amounts of copyrighted music. And there’s one industry that’s really good at suing people: it’s the music industry. However, one of the biggest repositories of music consent is baked in, and that is YouTube.
When — if you look at the terms of service for YouTube — any material you upload to YouTube, you grant Google a perpetual license to make derivative works of your content in perpetuity, anywhere in the universe, and that includes AI models. So Google could take all the YouTube music that’s been given to it and say, “Well, you signed the terms of service, you agreed to it. And therefore, this model that we have now built from your work, you consented to.”
Christopher S. Penn – 07:36
In a case like that, if Google then rolls out the music generation model, which they have, how does that change the moral aspect?
Ruby King – 07:47
I don’t think morals — I don’t think the moral aspect changes too much because if you’re trying to justify your morals by going, “Here, in the fine print, it said I can do what I want,” then your morals need looking at. Legally is different to morally.
Christopher S. Penn – 08:06
Yes. And legally, Google is on solid ground, whereas Suno is not necessarily.
Ruby King – 08:11
Yeah. So it kind of comes down to, as well, the Disney situation did — whoever — I don’t know the full story of that, but they’re kind of trying to get — because they signed up for Disney Plus.
Christopher S. Penn – 08:23
Oh, yeah, the whole thing.
Ruby King – 08:24
Yeah. Did they actually consent to that? Is it morally right to go, “Oh yeah, but you signed your life away when you signed that little box because you wanted to watch the Marvel movies at home. How dare you? How very stupid.” Did you actually consent to that? No, but we are in a society where if you do not agree to the terms and conditions, you can’t use the service. You cannot use the service.
For musicians, there are so many — there’s not actually that many companies that will help you be heard. So Spotify, Apple Music — there’s lots of others, but they are smaller and less used. You have to be on those if you want your music to be accessible to people because that’s where people are. You have to go there. It doesn’t mean I necessarily want to agree to the terms and conditions, but if I want to have a chance in heck of having that being heard by anyone, then you’ve got to upload there. The same with Facebook or advertising on Instagram. You have to have an Instagram page. You have to have a Facebook page to say, “Hey, this is where the people are. I have music I think you would like to listen to, and I’d like you to listen to it. Here’s a link on something that you probably have. Go listen to it.”
Along the lines, in order to be able to do all of that, you must have signed your life away at least 50 times, and there is no choice but that. You can’t be a musician in this day and age and have your music heard without signing your rights away. That’s a really difficult position to be in because we don’t want to sign those rights away, but you kind of have to take it as a risk.
Christopher S. Penn – 10:02
Cost of doing business.
Ruby King – 10:03
Yes, it’s kind of what you have to do. And now — but there never seemed to be anything that was happening that was bad, and now it’s, “Oh, AI has gone, ‘Hi. We stole all of your stuff a while ago because you consented to it, just to be clear. So that’s done now. Thank you. Bye.’” “Oh, okay. Yes, we did sign the things, but we had to. Is it really consent if you are forced to do it?”
Christopher S. Penn – 10:34
So from the perspective then of a musician or any composer, what is — what is your play to ensure that you have a career?
Ruby King – 10:45
Find a different field? I mean, that’s true at the moment, but no. I think it — I know it’s something you say. It was trying to have a personality and being a personality, I think that is a big thing of it. I’m terrified of that. I have accounts on multiple different social media platforms, but they are nothing as me — I am not the profile picture. I can’t do selfies. I look like the polite cat. It just doesn’t work, so I don’t really have them. I happily tweet about other things, but no one needs to know about me. I’m quite happy.
But you need to if you want to be successful because people need to see the behind-the-scenes in order to get as much justification for listening to it, because it could always be — it could be AI, or I could just listen to something else. It’s difficult. But another thing is creativity because, at the moment, AI is doing better. It is throwing in some creativity. However, it’s not always doing it right. So something else that musicians need to do is be themselves, be creative, and sort of think about it from the perspective of a listener. “Would AI do this?” You were saying that it’s sort of statistical.
Christopher S. Penn – 12:10
It’s all probability.
Ruby King – 12:10
Yeah, if it’s all probability, then do against — go against the probability. If your piece feels like it should end, don’t end it. Do a different section. Do a B section, maybe do a C section. Do something else that makes the listener go, “Oh, okay.” Because AI is doing that. But if you do it more, you win.
Christopher S. Penn – 12:30
And then you end up with Scenes from an Italian Restaurant, which is three songs smashed into one.
Ruby King – 12:34
Sure. But it does depend because you do have to be careful because not all creativity is necessarily going to be palatable. You can’t just chuck every single thing you could do musically into one basket and go, “This is not AI, I promise. Listen to it. You will love it.” Because you don’t want to hear a piece that changes key every five minutes, and all the lyrics are really strange, and then it suddenly goes into French, and the tempo changes so many times you’re getting used to it, then suddenly it changes. You’re just going to be, “I don’t — too much is too much.”
Humans have to know when that too much is just for the sake of it. If you want to do that anyway, then that’s fine. But that has to be an intentional choice that I don’t want people to sit here and think, “This is music I’m listening to for fun.” Usually, there are pieces where it’s — it’s a choice that you’re listening to it. That’s perfectly okay.
There’s a piece that’s sort of representing dementia, and it’s — I think it’s about seven hours. It’s a long one. I haven’t sat through it — I would have been very upset if I’d sat through the entirety of that — but it’s a very interesting thing to do with music because it was actually using samples of other older music, ballroom music. So it wasn’t quite the same, but it was doing a lot of compositional aspects with it and changing it to represent the stages of dementia. But to listen to that, it’s more of an art experience.
Ruby King – 13:59
AI might have been able to do it, I suppose, but a human would have had to put a lot of thought into it to go, “And at this stage, humans experience this. So you will do this to the music.” There still would have had to be a lot of humanity behind it to do it. I think that’s by The Caretaker, if anyone wants to look that up. Good luck. It’s very depressing.
Yeah, there’s a lot of different things with that kind of thing. But music, in order to stay ahead of the AI, you’ve got to keep an eye on AI as well. You can’t just go, “AI will do its thing, and I will do mine.” You sort of have to stay up-to-date with what it’s doing. If the voices are better — I mean, if you can play live instruments and add those to your tracks, do so because of the humanity of the stuff will help because AI doesn’t have that right now. So use it as an advantage. Do that. Sing on your pieces if you want lyrics, or have a choir. You can have choir patches, and the choir patches are more realistic than AI choir because they also move at once. It’s more like a chord pack, more synthy, which is fine, but it’s not a choir. So trying to do a church thing, it’s not quite right. I don’t know.
Christopher S. Penn – 15:15
It —
Ruby King – 15:16
It is difficult because it will always be improving. To some extent, I think in the end, if there is no more legal help coming to save us, then it will be more of a case of — it will be down to the ethics and preferences of the people who used to pay you and listen to your music as to whether you can still put food on the table from your music or if that’s even an option in the future. It’s a very sad, unfortunate situation, and I hope it’s not the case, but I do think that is very possibly the way that it is going, especially having seen the way that artists are being treated at the moment. Music was only a bit behind that, and as always, things kind of don’t go the way you want them to.
Christopher S. Penn – 16:07
That’s true.
Ruby King – 16:07
Yeah.
Christopher S. Penn – 16:08
Well, so having — having that AI portion is essentially going to be the mass-produced music, and then you will have the individual artisans who — people follow that musician because of that person and their musical skills. A machine could do probably very similar music, but you’re there for that person specifically. So it is almost building a cult of personality around you as a musician or a composer, etc., so that you have that army of true fans that are willing to support you because of who you are as a human being.
Ruby King – 16:50
And that also comes down to finding your own sound, too. So if you have a preference for the way that you prefer to write music, or music that sounds good to you, then that sort of becomes your sound. And that was true of artists, and then they said, “Oh, do this art in the style of XYZ.” And then it scanned all their art and did that, and that kind of took that out of the water, and it probably will with music, too. It has. If you say “Taylor Swift,” then you get a lot of Taylor Swift-ish music, and that’s only going to improve, probably. Although you said that the data —
Christopher S. Penn – 17:22
Well, so one of the challenges with music, in particular, is there are not actually that many songs. AI needs enormous amounts of data to train on. For example, a text language model needs between seven and ten petabytes of data of raw text to give you a sense of how much data that is. That is a bookshelf that goes around the equator of the planet twice in raw text.
Ruby King – 17:48
Okay, it’s quite big.
Christopher S. Penn – 17:49
Yes, it’s quite large. There aren’t that many songs.
Ruby King – 17:52
No.
Christopher S. Penn – 17:54
So you would have to upsample by essentially repeatedly training a model, “Hey, here’s a song again. Keep learning from it.” Or, in the case of things like music on YouTube, “Here’s the original. Here’s the 18 cover band versions of this song,” so that you can learn the predictable next sound of what should come next.
Ruby King – 18:17
Yeah. Musicians are taught to do the same thing. One of the main things you are taught as a composer starting out is, “Listen to other people’s music. Decide what you like. Decide what you don’t like, and do that. But then try and be creative about the way you do that,” because, obviously, plagiarism is frowned upon. So yeah, if finding a voice is important, but it isn’t going to save you. Finding a voice is hard enough on its own. You would hope that would be enough, but apparently nothing is.

In today’s episode, we’re continuing our exploration of music and AI with composer Ruby King. You’ll listen to more AI-generated compositions and uncover the surprising ways AI interprets and replicates musical styles. We’ll discuss the concept of “human touch” in music and how AI attempts to capture those subtle nuances. Tune in to discover the challenges and opportunities AI presents to the world of music composition!
Fireside Chat: Music and AI, Part 2: The Human Touch: Imperfections and Intent
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
Christopher S. Penn – 00:00
In this five-part series on music and AI, filmed at the 2024 Marketing AI Conference, or MACON, I sit down with composer Ruby King to discuss AI music and the future of creativity. This is part two, the human touch, imperfections, and intent. Let’s try another piece. We’re going to switch to something theoretically a Viennese waltz.
Ruby King – 00:21
We’ll find out if it actually is or not. That’s okay.
Christopher S. Penn – 01:58
So what was that? How was that?
Ruby King – 02:00
It was very interesting. It was quite nice.
Christopher S. Penn – 02:03
Okay.
Ruby King – 02:04
It was quite nice. The first thing I was noticing was — again, sort of going into “How was this recorded if it was by humans?” — and it sounded like — I could have been wrong because I’m sat away from it — but it sounded like there’s a bit of crackle on the recording.
Christopher S. Penn – 02:16
Interesting.
Ruby King – 02:16
A little bit. I was kind of wondering — it sounded like a recording that my old violin teacher would give me from her cassettes. It was, “This is what the piece you are playing,” and it was recorded a very long time ago in black and white. It’s just the EQ as well. The quality of the sound — it didn’t sound like it was recorded. It didn’t sound like I was in the room with it, and that’s not a bad thing. It’s just — it sounds like older recordings. So I’m wondering if maybe the info it was fed was from past —
Christopher S. Penn – 02:48
— highly likely, yeah.
Ruby King – 02:49
Okay. As to whether it’s a Viennese waltz, I can’t answer that because I don’t have — I can’t be sure enough. I’m not an expert, and someone will shoot me down online if I say one or the other things. I am going to back out of that one slowly.
Christopher S. Penn – 03:02
Okay.
Ruby King – 03:03
But it started faster, and it got — it had some really slow bits in it. That was nice. I was surprised by how many different sections there were that seemed to be trying to do a theme and variation. I’m not completely sure it did do a theme and variation because I think it might have forgotten exactly what it did or the music wasn’t memorable enough to remember. I would have to look at the actual notes themselves and listen to it quite a number of times more. But it sounded like it was attempting to do a theme of variation.
I think waltzes are usually three, four — goes a 1-2-3, 1-2-3. And most of that was, I think one bit seemed to be six, eight, six, eight, or six — my music teacher’s going to kill me — but sort of, where it’s longer: 1-2-3-4-5-6, 1-2-3-4-5-6. So it’s still the same feel, but the phrasing doesn’t stop midway through the bar. It ends at the end, if that makes any sense.
Christopher S. Penn – 04:02
No, it makes total sense.
Ruby King – 04:03
Okay.
Christopher S. Penn – 04:04
But it calls back to how the Transformers model works, where it’s doing things in chunks. Instead of sewing it back together, one of the things that you’ll notice with tools like Suno, particularly for longer compositions, they lose coherence, two and a half, three and a half minutes into the song. Sometimes they’ll just go totally off the rails, and you’re not sure why. But then when you look underneath the hood, “Oh, it’s because it’s doing 32nd chunks, and it either forgot, or there was a token that got misplaced in chunk 13 that just throws the whole thing off.”
Ruby King – 04:39
Yeah, that was — that was enjoyable listening. But another thing that — I’ve done violin for quite a number of years, and one of the key things I was listening to there was, “Is this a real human playing it? Is this playable?” Because one of the main things you can hear in music that’s violin or viola or whatever lead is the bowings. Most people don’t bother about this, which is why I’m insufferable to watch TV with, an Umbrella Academy. When they whip out the violin, I’m, “No!” Because it was a bit loud. Sorry. It was —
Christopher S. Penn – 05:17
— or Sherlock, where he’s not — what he’s doing, the hand motions don’t match the actual audio.
Ruby King – 05:22
It’s just so painful. Just get someone who can, please. We exist. Just the fingers — all the editors mess it up afterwards. I don’t blame them, but, okay, anyways. One of the main things is bowing, and you can hear it because if it’s up and down, you can hear how the string — it sort of — it changes. There’s a break in between the noise. If you’re slurring, which means going from one note to the other with the same bow, it’s only the note that changes. There’s not really a pause in the middle. So most of that was separate bowings, especially when it was doing quite fast jumps. At one point, it was — I pulled a face at one of — one of those face pullings was because it was doing something quite fast with a lot of jumping.
Ruby King – 06:10
Their right hand must have been going — it is very possibly possible, but that player deserves an award.
Christopher S. Penn – 06:21
Probably some aspirin.
Ruby King – 06:24
The way it would be chosen to play it — if the composers specified that would be how you should do it, then you would probably try and do it like that. But a violinist would naturally try and not do that much effort because it doesn’t sound right being so separate either. If it was more together, just in phrases, a few notes in the bar, maybe just — if it’s in three, four, then maybe six of those could have been in one bow and then another six in another bow, and that would have still kept the phrasing. But just the way that it’s performed, it’s not thinking about performance rules. It’s just thinking, “These are the notes, and this is a violin sound. Therefore, this is correct.”
Christopher S. Penn – 07:05
Right. So AI is essentially synthesizing from the outcome of the data but does not understand the techniques used to make the data.
Ruby King – 07:17
Yeah, I think so.
Christopher S. Penn – 07:18
Okay.
Ruby King – 07:19
Because there’s a few times there, I think, in that piece, it would have been nice if there was a slide up because it does do some jumps. The nice thing with the violin is it’s not a piano. I can say that I play both, but on the piano, you can do slides, you can do glissandos, but it’s easier on a violin because you can kind of slide up to a note and add some nice vibrato once you get there. Piano, it’s a bit more — you can’t get all those microtones between. So it’s kind of — because there’s —
Christopher S. Penn – 07:50
— defined intervals between one note. So if you are a content creator using generative AI, the instruments that have more analog between notes, like a violin, as opposed to being more defined segments, it’ll be more of a giveaway that you’re using AI because the machines are not synthesizing the technique needed to create the sound.
Ruby King – 08:13
Yeah. So it is said that the violin, or strings, are the closest thing to the human voice. And the human voice, we can easily tell, most of the time, when it is not a human voice. Okay. Saying that, there’s a lot of speech that is very good now, and you can’t really tell. Those models are very advanced, and it sounds very good. But singing isn’t quite there yet, I’m assuming, because there’s so many different techniques all the way down to breathing and where you hold your head. The sound’s going to be different if you’re looking up to — if you’re looking down. It’s just because there are so many variables.
So the violin and singing — the human voice — are dead giveaways. Well, voice more so than violin, because I think you have to be a bit more trained on violin, usually. But still, it is coming down to the subconscious. When you listen to that, are you thinking, “This is a real performer? I can imagine being sat in a concert hall?” Are you going, “This is a violin. I can’t say anything more about it than that”?
Christopher S. Penn – 09:19
Right. Okay, let’s try a piano piece. So this one is supposedly a ragtime. What’s that sound?
Ruby King – 09:33
Slides in there. It’s gone again. You’d expect the violin to come back in a minute. Just loosen that.
Christopher S. Penn – 10:59
So this is an example where it should have stopped.
Ruby King – 11:05
Unless it’s — ooh. I mean, it should have stopped if that was the intention. But if this was the intention, then that would be an impressive thing for a human to do.
Christopher S. Penn – 11:18
So the prompt on this was just, “Enough beat back then.”
Ruby King – 11:22
It’s just — it liked what it did, and it was, “I’m going to do more before you shut me down. I’m done now.”
Christopher S. Penn – 11:38
Okay, so that was an example, in particular with Suno, where it will have these — they’re almost hallucinations, where it sounds like there’s a logical stop of the song, and it’s, “I’m just going to keep going.”
Ruby King – 11:53
Was it given the time frame it had to be?
Christopher S. Penn – 11:54
No.
Ruby King – 11:55
No. So it just — it was just, “I’m having too much of a fun time here. You cannot stop me.”
Christopher S. Penn – 12:00
If I had to guess, and this is pure speculation, the model had enough fragments of enough tokens leftover to forecast from that it was, “I don’t know if I should stop or not.”
Ruby King – 12:12
Okay. It definitely — it did feel like it came to an end, but it continuing wasn’t necessarily wrong. So it wasn’t right for what you said, but if you were in a concert hall and that was played, and then there was a pause — and sometimes you do that, which is why you’re told, “Do not clap in the middle of a movement because you will look like an idiot, and everyone will stare at you, and the musicians will remember you for the random time you —” true story — then it’s kind of — it sort of felt like a different movement.
Christopher S. Penn – 12:46
Right.
Ruby King – 12:47
It was — the music didn’t necessarily feel connected, but it felt like a nice, different piece. So you might expect, if it was meant to be the same piece, you’d expect the first piece of music to come back again, and that would be sort of a bigger end, and that would be an ABA structure because you sort of have the A, and then the B, then it just ended. It was a nice end, but it wasn’t necessarily the way you’d expect a piece to be. A and B does happen. That is okay, but for the instructions you gave it, you’d expect it to go back to the A section. So it’s not that it’s wrong, it’s just — it’s not — it’s wrong for what you asked it to do.
Ruby King – 13:28
But musically speaking, if you handed that in, it would probably be seen as a good thing that you did something creative, a false end, and then you continued with something that was different, and it was an “Oh!” moment, which is a good thing. So musically, it’s good. Prompt-wise, not so good.
Christopher S. Penn – 13:48
Right. Okay, let’s try one more piece, and then I want to talk about how we can — for people who want to use these tools — how we can get better performance out of them. So this is the last one. This is the ragtime.
Ruby King – 14:20
Good bassline. It’s repeating itself. I remember that — for now. For now. Basic — good — oh, that is a variation of theme A. Oh, that’s definitely theme A. Half speed. Slower. Happy. That is — anyway, I can’t remember theme B well enough, but I remember A — is that key change, or is that just — okay, that’s all right. This is longer than I thought it could be, and it’s remembering itself quite well. You would probably want it to be doing something more exciting with this now because it is just feeling like it’s gone back to the start. The left hand should probably be doing something more interesting. It’s an odd end. I mean, it’s a valid end. It’s not what I would have done, but it — it ends fairly convincingly.
