In today’s episode, rich asks, there was a lot of discussion at a recent conference about implementing a large language model for on your own data.

Is this a reasonable expectation for a small business? It depends.

It depends on the small businesses capabilities on their technical prowess, and on whether they have problems that a language model could solve.

I mean, one of the most important things to do is to think about how do you use a tool like the like a language model to improve your business, there’s productivity gains, there’s obviously scaling content marketing and things.

But the question is, would your data make a big difference in tuning one of these bottles? The process for tuning is you create a large data set, you take a large amount of your data, and you create associated prompts that go with it, like write a blog post about this.

And of course, there’s your blog post that exists.

And that would be the response to that prompt.

And then taking hundreds of those, and pushing them into a tuning facility that allows a model to learn the kinds of questions and responses it should be giving and will nudge the model weights, the probabilities of returning any given word towards the data you’ve given it.

Now, the big question you have to ask is what problems do you want to solve? If you’re doing content generation? Yeah, that might be a reasonable expectation.

Because content generations probably content you probably have a good amount already.

You probably have internal content that could be useful for content marketing.

For things like operations, if you have existing templates, existing emails that you could use as training data, then you could it’s reasonable to say, that could be an expectation that small business could do it.

On the other hand, if you’re not sure about the use cases, then the first thing to do is to use the foundational models like the ones behind chat GPT or Claude or llama, etc.

And see if the the vanilla unflavored models can do those the tasks you want them to without having to fine tune it.

If you get great results from detailed prompts, and maybe some few shot examples in your prompts, then yeah, you probably don’t need to tune a language model on your custom data.

On the other hand, if you are trying to, to coerce a model into giving you a specific result, and no matter how detailed you make the prompt is just not doing it, then implementing a model on your own data with the fine tuning process might be the way to go.

So you’ve got to be clear about your purpose, right? We’re going to use the reference to trust insights five P’s, you got to be clear about your purpose.

You got to have the people in the skills to do it.

You should have a process for gathering your data, you’ll want to choose a model, a platform, and then measure the performance of the tuned model to say like, yeah, this tuned model works better than the off the shelf models.

That process is important to go through.

It’s basically requirements gathering before you spend a lot of time investing in tuning your own model.

I’m not saying it’s a bad thing to do that, because it does, it does work, it can generate great results.

But you may not need to do it.

If you can get similarly good results out of foundational models instead, but it’s an interesting question.

It’s a question that’s worth going through that exercise that five P framework exercise, so that you can understand Yes, this is something we should do or at least plan to do or no is this doesn’t make a whole lot of sense.

So good question.

Thanks for asking.

Machine-Generated Transcript

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

In today’s episode, Helena asks, What do you make of the zoom AI kerfuffle? So for those who are not familiar zoom, the company that makes the ubiquitous video conferencing software changes terms of service to say they would use customer data to train their language models to train generative AI.

This of course created a quite the firestorm of people saying was a violation of their privacy and so on and so forth.

Zoom then retracted that policy and altered to be exactly the opposite actually to say from now on we’re not going to use customer data to train our AI.

This raises a much bigger issue for pretty much every company, pretty much every company, but especially companies that are in the tech space that provide tech services are scrambling to have and find and gather up unique data sources.

Here’s why most of the large language models that are out there, like open AI is models like the llama family from Facebook, etc.

These models are all trained on public data, which means that there really isn’t a big competitive advantage for one company to use one model over another.

Right? If you were to take one of these models and tune it or train it on your company’s proprietary data, the data behind the scenes that could give you a competitive advantage, your model might be better at asking and answering the kinds of questions and content generations that are unique to your business unique to your way of doing things.

So it’s no surprise that we see companies like zoom and many others saying, hey, we’re going to do what we can to leverage the data we have access to, to make a model that works better for our specific use case.

You can think about in the video conferencing space, right? How many different companies there are in the video conferencing space? How many companies have all this transcription software of one kind or another? And could they use that knowledge base to get better transcription to answer questions to predict the topic of a call, and so on and so forth.

The company that leverages data the most smartly would be able to offer that as a service.

Now zoom kind of went out about it the wrong way.

The wrong way was just to make a change to the terms of service.

And, you know, does essentially force people into that policy.

That’s not a smart way of doing it.

And they found out the hard way that a lot of people really don’t like that.

The right way to do it is to acknowledge the value of the data.

If if you are running a piece of software, and you are collecting user data, and you want to leverage it, ask users to opt in and maybe offer them an incentive, right? Say like, hey, we charge, you know, $300 a month, we will knock 25 bucks off your fee every month if you opt into this plan that allows us to anonymize and use your data to train some kind of AI service.

That would be ethical.

That would be lawful, compliant with privacy policies.

And it gives users the choice to say like, what is my data worth? If I say, Hey, I think my data is worth more than 25 bucks a month, you don’t opt into it.

If you say, you know, 25 bucks is 25 bucks, I’ll take it.

Particularly if it’s maybe on a per seat basis, it might be considerable savings, say check the box.

Yes, I’m in.

This is going to become a bigger and bigger problem for everyone as AI continues to proliferate everywhere as everyone wants to have their secret sauce, their secret model, their secret library of training data that will improve the performance of foundation models.

And that’s really important.

Again, that you should expect this kind of strategic pivot, and not necessarily the way zoom did it.

But in general, a company is saying, you know what we need to get better at using this data, we need to get better at we need to get better at making use of the data to make our our AI smarter for our company and the companies that do that the best will have better AI that generates better results that creates competitive advantage.

So my thoughts on it, ask people ask for permission, maybe incentivize participation, definitely don’t do it just by forcing everyone into it that tends to never go well.

But recognize that everyone and anyone who is aware of the capabilities of AI is going to want to do that and may even need to do that.

Using customer data using proprietary data sooner rather than later.

Thanks for the question.

And thanks for tuning in.

Machine-Generated Transcript

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

In today’s episode, Briar asks, How do we program a voice of a CEO or expert we frequently write for? So that we can use their voice? Well, okay, so there’s, there’s a bit of ambiguity here. If you mean the speaking voice, that’s one avenue, if you mean just their writing style, that’s a different avenue.

So let’s tackle the writing style first. If you want to capture someone’s writing style, there are there’s a technique called neural style transfer. And essentially, using a tool like chat GPT, the paid version, or Anthropics, Claude to you would take a large sample of someone’s writing, ideally a diverse sample. So blog post, an article, some emails, maybe some social media comments, something that a body of work, and we’re talking probably a couple of pages, at least, of text that really encompasses how a person speaks their voice, if you will.

That then gets fed into one of these large language models with a neural style transfer prompt. And essentially, it’s, it’s pretty straightforward. It’s like you are a world class writing expert, you know, style transfer, writing styles, author voices, blah, blah, blah, all the keywords and phrases that would be associated with writing styles. You would say your first task is to do a detailed analysis of this person’s writing style in bullet point format, and it will generate a long list of these things. And then you would use that bullet point list, essentially as its own prompt to apply to the next piece of content you want to generate, you would say something along the lines of using this defined writing style, writing an article about x, y, or z. So that’s how you capture someone’s voice in text.

If you were talking about the actual cloning of someone’s voice, using a tool like voice gen tortoise or 11 labs, you need to start with good quality sampled audio, ideally something that’s made professionally with you know, a good microphone. You can use a smartphone as long as the environment in which you’re recording is pristine. The best place to do that if you don’t have access to an actual sound studio is if you know somebody who has a like a nice car, like Alexis or something where it’s it’s quiet inside. Make sure everything is off in the car. Obviously don’t do this in the middle summer will suffocate. You put the phone four to five inches from the person’s mouth turn on the voice memos app and you have them recite some scripts.

And the scripts that you want to have them recite. This is one of the catches with voice transfer should not be business content should not be a blog post because what you end up with when you have somebody reciting a blog post or business content, you get something that sounds like this. Trust insights will build a media model mix using stock performance data public relations campaigns and efforts organic search data public relations scenes outcomes. See what I mean? It’s very flat. There’s there’s not a lot of intonation. There’s not a lot of there’s not a lot of emphasis or variation.

So what should you use? Ask the person that you’re working with and this is something that you want to do in detail. Ask them for what their favorite TV show is and then go online, find a script from that episode of the episode that show and ask them to you have to do a little bit reading we want to ask them to read out some of their favorite shows script because it’s going to sound very different if they’re reading from something that’s a lot more dramatic, right?

You would see something like Yeah, I’ll read a segment here from a piece of fiction. You know, let me check the photon account. That doesn’t make any sense. She’s she’s calibrated the photonic gun to aim inward instead of down the test range. I don’t understand it’s like she’s holy shit, she’s gonna shoot it at herself.

You see how much more variance there is in the voice. That is the kind of sample that you want to use for any of these voice training tools because they are looking for variation. They’re looking for variants, they’re looking to learn as much as possible about your voice. And if you were just reading in a monotone or capturing the sound somebody’s voice in a monotone, it’s gonna be much harder for that software to capably generate good, varied audio.

If you have wildly varying audio, the tone and inflection things that really capture how a person really speaks, then you’re going to get a much better sample going to get much better output. And with a tool like for example, 11 labs, they’ll ask you for 10 different sound samples of varying lengths, you know, 30 seconds, a minute, two minutes, but it’s not how long or how much data you provide, it’s how diverse the data set is you want that variance.

So that’s my suggestion. Another way to do it would be to have them maybe recite as as prose recite as poetry, some of their favorite song links not to sing it, because you don’t want the musical intonation, but to read out some of their favorite song links, because you’ll still get some of that rhythm, you’ll still get some of that variation that variance in their voice that will capture the essence of their voice.

So that’s how you would do that. How you would you follow the steps in the software of your choice. But that’s how you do the sound samples so that you get good quality. Now, if the person that you’re working with has a body of public record already, you know, someone who’s an actor, someone who has been on a lot of podcasts, someone who does earnings calls, things you can go through those archives manually, and identify segments and snippets like, you know, this one time Bob was really yelling at that analyst on that call, okay, great, let’s take that segment, slice it down to 30 seconds or a minute or whatever the software requires, then you can put that in the training library for the way that these tools will memorize information.

But the key is that variance in tonality, and the way they speak in their actual voice. So those are my suggestions if you want to do a really good job with the actual voice and for capturing someone’s writing style. It’s a really good question. This kind of training data, gathering it polishing it is going to be really important in the next couple of years, right? The big challenge of AI is not the AI systems is having the data needed to generate good results.

So the sooner you get good at doing stuff like this, the easier it’s going to be for you. Thanks for the question and talk to you soon. If you’d like this video, go ahead and hit that subscribe button.

Machine-Generated Transcript

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

In today’s episode, Alexandra s can you explain the copyright issue when it comes to AI generating content? Can I use the text to generates for an email or not? What about programs like Jasper campaigns that generate social media posts that are doing the same? Okay. Let’s talk about copyright.

I am not a lawyer. I am not a lawyer. I cannot give legal advice. To get legal advice, you need to contact and work with an actual lawyer for your specific situation. I recommend my friend Ruth Carter. They have a law firm, geek law firm.com. They can give legal advice. I cannot. So as long as we’re clear about that.

In the USA and most places now, but especially specifically in the USA, which is where I’m based. Under US copyright law, copyright can only be held by humans. There’s a famous case in a road over a slater from 2018, in which a chimpanzee took a selfie with a camera. And after a number of lawsuits and court cases, the US Copyright Office and the courts ruled the chimpanzee is not human, human can hold copyright. Other entities cannot.

Therefore, if a machine generates something, that thing cannot be copyrighted. There is no copyright applicable, even if it’s coming from a machine that you own. Even if it’s coming from a service you pay for, it cannot legally be copyrighted. And it doesn’t matter what the terms of service on the software say, because there’s a lot of different companies have all these disclaimers and things in their legal statements.

The law is as of 2023 in the USA. Machines cannot hold copyright, which means that if you generate text for an email, yeah, absolutely. You can use it, right? Anyone can use it. Copyright means that only a certain authorized party is allowed to use something without negotiation or compensation, right?

If this book here, the author is Daniel Goldman, this is his intellectual property, I cannot remove you know, scratch out Daniel Goldman, put Christopher Penn on here, I cannot do that because he owns this work. He’s a human, he owns this work. It is his copyright. I can still use this book, I can still read this book. I can even summarize this book. Legally, I just cannot claim it is mine, right? Because that’s stealing.

When a machine creates something, because it’s not human. The moment it creates something, it is public domain, anyone can use it. So right, having a machine summarize your last staff meeting, great, you can use that you can use that all as much as one, you can’t claim ownership of it. Right.

So if you publish a blog post that you know, chat GPT wrote, you can push that on your blog, you can you can have it out there. If someone else copies it, you can’t sue them for copyright infringement because you do not own it. You there is no owner of that intellectual property because it was made by machine. And therefore, if somebody else copies and paste your blog that you made with the machine, you have no legal recourse. You can’t do anything about it.

Now, this is where we start to get into splitting hairs because there are different situations. Here’s two situations I’ll give you one, you write a very detailed prompt and chat GPT will use that as the example chat GPT spits out a blog post. The blog post cannot be copyrighted because it was made by machine. You can copy right your prompt. Because you wrote that you as a human wrote that but you cannot copy right the output from machine.

Flip that around. chat GPT gives you a detailed outline for blog post and you write the blog post, you can copyright that as long as you do the writing the final product is made by your fingers or voice or whatever. You can copyright that because you did the work even if the ideas came from a machine because ideas can’t be copyrighted. The work itself can be copyrighted.

So you can use anything from any machine if you know that it came from a machine, whether it’s chat GPT or Jasper or write.ai or whatever service go Charlie doesn’t matter. You can use it. But you cannot copyright it and no one can copyright it because machines cannot hold copyright at least in the USA.

Now this area of law is evolving for obvious reasons. So if you have concerns if you want to talk through well how should we approach this? How do we protect our intellectual property rights? hire a lawyer, hire my friend Ruth, but hire a qualified attorney to guide you through the process so that you know what to do and what not to do.

So that’s the answer to your question. Hope it was helpful. Thanks for tuning in and I’ll talk to you next time. If you’d like this video, go ahead and hit that subscribe button.

Machine-Generated Transcript

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

In today’s episode, Julie asks, there are so many competitive tools in AI that are continually evolving. How do you stay current and align with the best tools based on what is needed?

The answer to that question is at the very end of your question. You got to know what’s needed, right? You have to know what is needed in order to evaluate tools. It’s the Trust Insights 5p model purpose, people process platform performance. What is the purpose you’re trying to accomplish? Once you know that the rest can start to fall in place. But if you just go in tool shopping with no clear idea of what you want, what you need, it’s not going to work out very well for you.

Imagine going to, you know, Home Depot or Walmart or Target or the store of your choice. And to start buying kitchen appliances, like you don’t have any thing you want to cook in specific, you just start buying appliances, a blender, frying pan, air fryer. And you’re by the time you’re done, you’re like, Oh, well, this looks like the best blender. And then later on retroactively, you go, Oh, he wanted us to make steak. This blender won’t help all that much, right? That’s the problem with the tool centric focus. A tool centric focus is one of those things where yeah, there’s, you’re going to pick the wrong things, because you’re not focused on what you need, not the tools.

Now, how do you keep up with the sheer number of tools? In the AI space, here’s the thing. There are hundreds of new AI tools every week. And these are mostly what I call wrappers. A wrapper is exactly as it sounds like a candy wrapper, something that is that is around a piece of something else. These tools are wrappers around other people’s API’s like open AI or anthropic or a name the service of your choice. And as a result, they are there may not be a whole lot of value added on top of what they have built, right? It depends. It’s a case by case thing. But many of these tools when you when you look at them, when you read about them and you go, huh, this tool is really just an interface onto GPT four or Claude two. And it’s an interface that essentially just translating what you what would be a prompt you would type into something slightly easier to use. But it doesn’t have a huge amount of value add on top of it. And then you have a company essentially charging money for something you probably could have done on your own.

So once you know what you need, the second thing you should understand are the foundational technologies, right? What are the the pieces that you would need if you wanted to build it yourself? I’m not saying you have to, in many cases, you probably should not. But knowing what’s running behind the scenes, what’s under the hood can be a great help in narrowing down what it is that you want to do.

So if you’re doing language modeling, should start by saying, Okay, well, what are the foundational ways to use language models, there are models that are API’s like chat GPT is essentially an interface onto GPT four models. So it’s an it’s an interface you can you connect directly with the GPT four model. And many, many software companies are doing exactly that.

So that’s one sort of foundational piece you could connect to anthropic you could use be using the llama family of models from Facebook or the hundreds of derivatives of that. You could be doing voice you could be doing interface with something like 11 labs, or tortoise text to speech.

Knowing the foundational pieces and how you would build something then makes it a lot easier to vet vendors, right? You know, you know that enough know what’s under the hood, even if you can’t take it apart, right? So opening up your car hood, you can say, Okay, well, there’s the engine block, there’s the battery, there’s the windshield wiper fluid tank, and you put the hood back down. I don’t need to take apart my car to open the hood and go, Okay, I know what the general areas of my engine are. But knowing that gives me some understanding of how the vehicle works about what it can and can’t do.

So if you have a foundational understanding of the different technologies, voice generation, image generation, text generation, then when you start talking to vendors, and evaluating different tools, you can say, okay, this vendor is probably an ensemble of three or four different tools, or maybe this vendor has their own thing that they’re doing that is custom and unique to them. You know, maybe that’s that’s something that there’s lasting value there.

I personally would be looking at vendors that are using open source models, because a system of service like for example, the GPT for API from open AI, if opening I went out of business tomorrow, not saying they’re going to but if they did, you’d kind of be stuck. And if you’re using a tool that is going to be part of your bread and butter, you know, the, the, the strategic advantage of your marketing, you want something that’s going to stick around, right?

If meta went away tomorrow, the llama model would still exist, right? Because it’s been mostly open sourced, it it’s going to exist as independent of meta now. So they’ve made it public. And now people can run with it and do things with it that they can’t control anymore. So that’s an aspect as well as looking at tools and how much control a vendor has over their underlying tech stack.

These are all questions you would ask to the salesperson to the sales engineer, especially when you’re evaluating software and evaluating, you know, is this the right tool for the job? What is the job? What’s the right tool for it?

So those are some of the ways that I like to look at the myriad of technologies. And the questions I’d like to ask to see who is who’s the real deal and who’s not one last piece of advice. If a company will let you talk to engineering on chaperoned by sales, there’s a good chance that that company knows what they’re doing right that they’re not selling smoke and mirrors. Because engineers generally tend to be fairly honest, right?

I remember talking with one vendor, the sales person with the sales guy was like, Oh, yeah, our product is this this and this. And I went and talked to the engineers, the engineers are like, I don’t know any of that. What the heck is he talking about? They said a little more rudely than that. But he’s making things up there. Our product does not do those things. Our product does x, y and z.

When I when I vet vendors for myself or our clients, I try to talk to engineering, I try to ask engineers like what is the product actually what are the limitations? What challenges are you running into right now? And the more access I’m given to engineers at a company, the more faith I have that company that they don’t have anything to hide, because they’re willing to let them let the nerds talk to each other essentially, and the sales folks in particular at those more progressive companies understand that yeah, the engineers may say things that could be deal breakers, but probably not. If they feel comfortable enough letting people talk to engineering directly.

Anyway, that’s how I stay current on AI tools. Your process will probably vary. But those are some things to think about. Thanks for the question. We’ll talk to you next time. If you’d like this video, go ahead and hit that subscribe button.
