Christopher S. Penn – 00:00
In this week’s In-Ear Insights, happy New Year. Happy 2025. We are just getting started, and one of the big topics that we’re going to be talking a lot about this year is local AI, also known as private AI, open models, open weights. There are so many different ways to describe this set of technologies, but what it basically means is running a language model—generative AI—on computers that are under your control, that you run either literally on your laptop, in a server that your company owns, or in a private instance like IBM Watson X. So, Katie, to start things off, as the less technical of the two of us, what questions do you even have about this, and what’s your perspective so far on local AI?
Katie Robbert – 00:50
It’s one of those things. So, you talked about this. I guess the cat slash dog is out of the bag. I am fostering a four-year-old Newfoundland named Georgia, and she is recovering from surgery on the futon behind me. She is a menace. She is a very sweet girl, and she is going to be guesting on our podcast today, apparently. So, hi, Georgia. She has her surgical suit on as well. It kind of looks like a suit, a super suit.
Katie Robbert – 01:24
You talked about local models again at Macon in 2024, and I think it’s such an important topic. But a lot of stuff that we do and talk about, it was a little bit ahead of its time because I feel like people are still wrapping their heads around how to get anything decent out of generative AI through their prompting. They’re not even at the point where they’re thinking about the infrastructure of it. They’re just like, “Can I get something useful out of ChatGPT?” And so, you said it’s a local model, OpenAI, local AI. There are a lot of different ways to call it. So, I guess my first question is, what is it? What is a local model? And the second question is, what is the correct terminology?
Katie Robbert – 02:20
So that if I need to ask somebody a question, I’m asking about the right thing.
Christopher S. Penn – 02:25
Those are good starting points. So, what is it? Generative AI models—we are familiar with the big-name ones: GPT-4O, Anthropic Claude, Google Gemini. Open models, local AI—again, there are a bunch of different terms—are models that you can download and run on hardware and software that you control. So, there’s a website called Hugging Face, named after the emoji, where developers and model makers can post their models, and you can download them for free and run them. Some of the best-known open models—and I call them open models, that’s my personal preference. Local AI is also—local AI is sort of an umbrella term—but some of the best-known ones are models like Meta’s Llama. So, Meta, a company formerly known as Facebook, publishes this series of models called Llama that are incredibly powerful and very robust.
Christopher S. Penn – 03:31
And they run locally on your computer. You can download them from Hugging Face and install them. Mistral, the French company, is well known for its models. Alibaba Cloud makes a series of models, one called Qwen and another called QWQ, which does not roll off the tongue well. IBM makes a family called Granite. And so, there are all these different models that exist that you can download and run. Now, in terms of the terminology, some people call them open-source models. That’s not correct because open-source means that you can download the training data, and for most models, you cannot.
Christopher S. Penn – 04:08
An open model or an open-weights model means that the statistical database that makes up the model—which is what GPT-4O is and what Gemini is—is something that you can download and install, and you don’t have to pay someone else for that. You just download it, and it’s open, and you can take it, and you can tune it. You can do things to it, to remix it in some ways and customize it for your purposes. Local AI refers to the model but also the software you need to run it because a model itself is just a database. You need to have a server and a client. The closest analogy is when you have a website. You have a web server that serves up your website, and it’s hosted—sometimes it’s hosted, sometimes this is a box in your data center.
Christopher S. Penn – 05:03
And then you have web browsers, which are the client, which is what everybody uses, a web browser. You can use a web browser, but without a web server on the other end, that’s kind of a moot point. And so, in the same way, local AI has a client and a server. The server runs the model and serves it up—and it could be just to you, it could be people in your organization—and then you have the clients, which, again, could just be you or could be a group of people within your organization. So, that’s local AI. Local AI is the big umbrella term. Open models are the engines, and then there’s the other infrastructure as well.
Katie Robbert – 05:36
Well, so that answered a lot of the questions that I had because, for example, you’re saying you can download a model—and essentially just a database—and you can work with a database offline. It doesn’t need to be connected to the internet because essentially, it’s just data. But in this sense, I would imagine you would want it to be connected to the internet, and that’s where the servers and the hosting come in. Is that correct? Am I sort of along the right lines, or is the idea with these local models that you use them without connecting to the internet so that you’re really, for lack of a better term, sort of firewalling it from the rest of the internet and putting up some sort of governance and protection?
Christopher S. Penn – 06:19
And that’s one of the key benefits of local AI: is that you can run both the client and the server, say, on your laptop with no internet connection, and it will function. Local AI typically does not have—the model itself doesn’t know that the internet exists. It is just a database. The infrastructure software, like the client and the server, those, depending on whose brand you use, may have tools to do web searches and things that a model can know to ask for. But maybe it would help to show a practical version of what this looks like, just so people get a sense of it. And if you’re listening to this, you can catch this on our YouTube channel. Go to TrustInsights.ai/YouTube. So, what I’m showing here is a piece of software. This is called LM Studio.
Christopher S. Penn – 07:16
It is free, but it is not open-source. It’s free. And LM Studio is both client and server, so it’s everything in one package. I can go into LM Studio. I can choose a model that I have downloaded. In this case, I’m going to choose the Mistral Small Instruct model. I’m going to load it, and then once it finishes loading, I can chat with it like you would chat with ChatGPT. And it is as capable as the model maker has made it. So, this is client and server in one package that I can talk to and say—and I’ll show you an example of its knowledge is limited. So, I can say, “Who is the CEO of TrustInsights.ai?” And it says…
Katie Robbert – 08:04
Get out of here. Okay, so that model’s out.
Christopher S. Penn – 08:07
Exactly. But this is an example of what local AI looks like. It is, in this case, there’s a—the client and servers in one piece of software, and you can have a chat with it, and it can do things like summarization, some level of generation, and stuff. But there are many more considerations with this tool than there are with, say, a ChatGPT.
Katie Robbert – 08:31
So, as a non-technical user who’s still trying to figure out what all of this means—like for me, for my team, for my company—I guess first and foremost, my first question is, if I say the term “local model,” is that correct or incorrect? Is that a variation of it?
Christopher S. Penn – 08:51
It can be a variation of it. So, again, the model is the database. You could have a local model, but the local AI also includes the client and the server. So, it’s database, client, server—the three pieces of local AI.
Katie Robbert – 09:02
Okay, and then the other question—and this is the big question and sort of why we’re talking about this—is, why is this something that should be on my radar? Why is local AI something I should know about versus, “Well, I subscribe, or I pay for ChatGPT. Why do I need a local AI as well? That sounds like a lot of work.” What are the benefits of that versus, “I don’t know, I mean, I’m not putting any PII into Claude, so what does it matter?”
Christopher S. Penn – 09:37
So, there are three considerations. Number one: privacy. When you’re running local AI, like I said, you can unplug your—you can turn your Wi-Fi off, and it will run. No data ever gets sent anywhere from a local AI instance. It is all self-contained, which means that if you have PII or PHI, for example, you can use this with it safely. So, if you are, say, a three-letter government agency, you probably have a room full of servers in the basement in Langley, Virginia, and you’re going to run Meta’s Llama 3.1 because you can put that in a server in a concrete room, no internet, nothing in or out. And it is safe, it is secure, and you know that your data is never going anywhere.
Christopher S. Penn – 10:21
So, those case notes you’re getting from your agents in Damascus are going to be safe. You don’t know that you can trust Google or OpenAI or Anthropic with that sensitive level of data. So, that’s number one. Number two is cost. Most of the ways people use AI today are very consumer-focused. You open up ChatGPT, you ask it for a blog post. Those are good use cases when you start doing things. For example, when we did our Halloween candy episode, we had to scan through 7,000 articles and extract out all the Halloween candy names. If I had done that—because you have to do it with code because you don’t want to copy-paste 7,000 times—if I had done that with OpenAI, you would have gotten a bill for a couple of hundred dollars.
Christopher S. Penn – 11:13
And you’ve been like, “Chris, you can’t do this again.”
Katie Robbert – 11:17
I would have said, “Not worth it.”
Christopher S. Penn – 11:20
Exactly. When I use a local model, it’s the cost of electricity, because I’m running it on my laptop, and therefore, there’s no additional cost. So, that’s consideration two. Consideration number three is sustainability. OpenAI’s Q* model, which came out at the end of December—big fanfare, it’s not available to the public yet, it’s still in testing—uses, for one prompt, uses enough electricity—the same amount of electricity as a single-family household, a single-family home for three days. It uses something like 20 to 60 megawatts of energy. For its most complex prompt, it uses enough electricity for one prompt—a standard US household single-family home uses for a year and a half.
Katie Robbert – 12:15
It is, yeah.
Christopher S. Penn – 12:17
When you are doing things like summarization, extracting out Halloween candy names, you don’t need to use Google’s mega data center and spend 3 megawatts of electricity on a prompt like that. You can use local AI and know that you’re using 60 watts of power, whatever your MacBook or your Windows laptop takes. So, if your company is true about its values for sustainability, something actually matters to you, local AI is the much more sustainable option. And I guess the fourth one is business continuity. OpenAI is burning billions of dollars a year. If they go out of business, the investors are like, “We’re tired of flinging billions of dollars at you,” and they go away. Guess what? The local AI that’s running on your laptop, that is yours forever.
Christopher S. Penn – 13:07
Now, it may not get better, but what it does, it will do for you forever. And you have it. You can never be taken away from you.
Katie Robbert – 13:14
And I think that—so there are two things that really stuck out to me. So, obviously, compute cost is a big deal, but for some companies, that’s just something that kind of flies under the radar and just hits a credit card. Nobody even really pays attention to that. It’s the privacy and the sustainability that really, as an executive, are the things that would perk my ears up to be like, “Oh, okay, you have two really solid points that I need to think about.” The privacy is a big one because even if you’re not needing to put, PII, company information, whatever, into generative AI, that doesn’t mean it’s not accidentally getting in there from someone who’s maybe not as knowledgeable. Accidents happen.
Katie Robbert – 13:58
Or maybe you’re like, “I really just want to analyze our P&L to see where we can do better.” Those are all really simple things that you can use generative AI for, but you don’t want to use a public model to analyze your finances, to even think about your marketing strategy. It’s your marketing strategy. So, while it’s not personally identifiable to you, it’s still, in some ways, your own intellectual property. It’s your thinking, it’s your ideas, it’s your campaigns, it’s your execution. Depending on what industry you’re in, it could be highly competitive. And that’s the kind of information that you can’t risk having leaked. So, there are a lot of good, valid reasons to really start to think about privacy. The sustainability is the other one.
Katie Robbert – 14:47
I’ve talked about business continuity before, and what happens if all of our SEO tools that we’ve been using forever are suddenly—they’re all bought out or they decide that they’re no longer going to do SEO, and they’re going to do, I don’t know, paid ads, just as a really terrible example. So, you can’t get that organic data anymore. Where do you get it from? What’s your backup plan? We talked about this when Google Analytics 4 hit the market, and everybody sort of jumped ship. They’re like, “Well, I can’t use this anymore. What do I do?” That’s a really good example of why having business continuity plans in place are important, not just for if and when the inevitable employees leave.
Katie Robbert – 15:34
Technology is going to leave, it’s going to fail, it’s going to change, it’s going to do things that you didn’t initially intend it to do. Your company’s going to grow, your goals are going to change, you’re going to outgrow the technology, whatever the scenario is—all a very long-winded way of saying business continuity and privacy, to me, are the two big things that stick out as really big reasons why one should care about getting knowledgeable and skilled up on local AI.
Christopher S. Penn – 16:08
Exactly right. This stuff, because it’s mostly open-source and open-weights models, isn’t—that won’t cost you money, it’ll cost you time. It may cost you some frustration, may give you some extra gray hair, but it’s good to have it available. Even in a micro-business continuity perspective, whenever OpenAI comes up with a new announcement, what happens for the week after? Every service they have is unreliable, and there are a whole bunch of “ChatGPT is down” complaints on the social network of your choice. Well, if you’re in the midst of client reporting, if you’re in the midst of something that’s mission-critical, and you have only that tool in your pocket, you got a rough week ahead of you.
Katie Robbert – 16:50
Well, and think about the companies that have been really going all in and pivoting towards AI services. And, “Everything we do is with AI,” and it’s actually—when you start to dig into what those companies are doing, it’s a very fragile infrastructure because it’s not based on a solid foundation of repeatable process that you introduced AI into. It’s, “I built my process wholly in AI, and I’m not thinking three steps ahead where, what if it goes away, or what if it changes?” So, I feel like, yes, having a local model, local AI, does sound a little bit more daunting, but it does give you that control over if and when you want to upgrade the model, change the model. Let’s say the model does exactly what you need it to.
Katie Robbert – 17:44
You may not have to change it for a very long time, especially if it’s doing things that are exactly what your clients need. They’re not looking to do things that are cutting-edge all the time. They just need the basics. Great. Then you don’t need to be reliant on publicly facing models that are constantly changing, and then you have to go back and change your prompt structure, and then you have to change the inputs, and then you have to change the API call. I’m exhausted just thinking about it.
Christopher S. Penn – 18:13
But you’re absolutely right. So, over the holiday season, Google came out with Gemini 2. It came out, it’s available in Flash and Advanced. It’s not in production yet, but it is available for people to test. And I did some testing of it. Its prompting structure is very different. What it thinks a good prompt is very different. Some of my prompts, like the ones I use for this podcast to clean up the transcript, totally different now. I had to regenerate them, and I look at the old and the new side by side. I’m like, “This is a very different model. This is—they changed something in the architecture that makes this very different.” And so, if that was in production, if we were doing that for clients, we would have had quite a scramble.
Christopher S. Penn – 18:54
Now, granted, companies—all these companies are getting better about saying, like, “Hey, here’s when this model is going to go live, here’s when it’s going to get sunset,” etc. But that goes into a larger discussion for enterprise planning of, how do you do the change management of technology? Companies have had this in place for decades now for things like, “Which version of Windows are we going to use?” but it’s something that you have to think about for AI. And people are still so much on the frontier of the latest and greatest shiny object that you’re not thinking about, “Well, how do we manage models in a way that is organized and produces the least number of surprises for our customers?”
Katie Robbert – 19:34
Well, and the Windows operating system is a great example I used. I’m sure most of us started our careers in companies that were Microsoft shops. And so, we all dreaded the day when things like Windows XP rolled out, and it basically held up our machines for two whole days updating. Or, if you put off the updates and finally, the updates force themselves, you had like 25 hours of updates that were just going to cycle through regardless of what you had to do that day. And maintenance of technology is something that gets forgotten about and is done so poorly. There’s a whole set of skills that go along with that in terms of project management, in terms of QA, in terms of development. It touches so many things.
Katie Robbert – 20:34
So, when I worked at the company where I was managing the software development team, when we had to put maintenance pieces into the product, or we had to put together the maintenance plan of the things that were developed, it wasn’t just the software development team. We had to include the data team, we had to include creative, we had to include marketing, we had to include sales because every single one of those departments would be impacted by whatever we were doing with the maintenance. This is no different. This is just software. And if you don’t have a solid software development lifecycle within your company, if you’re not a company that’s ever done software development, this is going to be pretty mind-blowing because there’s a lot to it. Now, do you need to go find 20 developers? Probably not.
Katie Robbert – 21:23
But you should probably have someone on your team who understands what it takes to do proper maintenance of software. That could be a product manager, that could be a QA engineer, it could be a product architect, but don’t just wing it.
Christopher S. Penn – 21:39
So, here’s an example. This is the GitHub desktop application. This is for interfacing with code. Now, to be clear, for everyone watching, listening, this is not going to be your usage level. This is very technical usage, so this is not something you’re going to need to do. But this is looking at the repository for a piece of software called Kobold C++, which is what I use myself to serve up local models. There are 82 pending changes. So, what I do every Friday afternoon, I have time blocked where I update all of my AI software. So, if there are updates available for Kobold or for Whisper or for LM Studio or for, oh, Llama, Friday afternoon’s when I do it. So, I have the whole weekend to fix it if I have to.
Christopher S. Penn – 22:24
Because, for me, yeah, this is a very rare—this is not the use case you’re going to use. Once I hit update, I then have to recompile all the software. I have to rebuild it from scratch because you have to do that with every new version. So, you need these processes in place for enterprise usage because this is how you’re going to manage version control. This is how you’re going to manage change management internally. So, local AI comes with a heavier maintenance cost. When you use ChatGPT, all this is managed by OpenAI. When you use Google Gemini, it’s their responsibility to handle all this stuff. However, it comes with those trade-offs: less privacy sometimes, higher costs sometimes, and things like that. When you’re doing it locally, you are incurring those costs.
Christopher S. Penn – 23:14
So, as much as I love the benefits, there is a price to pay.
Katie Robbert – 23:18
Well, even so, let’s say someone isn’t doing it to the same intensity that you’re doing it, Chris, there’s still—even if you just chose one of those systems, you still have to go through that process. Now, you’ve been working in software long enough to know that you have to build in that time. So, now what you’re—what I’m hearing you say is you’ve actually taken time out of your schedule that you could have been doing client work that now you have to actually block off time to maintain, to update these different systems, to then do a QA check to see what broke, what changed, what do you have to fix. That takes time, but you’ve built it into your schedule so that now it’s just part of your internal process. But what it does is it prevents.
Katie Robbert – 24:05
Monday morning, you open up your computer, and everything’s broken, and then there’s a scramble, and then you have to send out all the apology emails to the clients to say, “Oops, sorry, all of our stuff broke. So, you’re not going to get the report that you paid for another two weeks while we figure it out.” A little bit of time up front versus a lot of time on the back end. It’s the same old conversation of, “Just do the planning up front.” If you plan to do the maintenance up front, you won’t be surprised by it on the back end.
Christopher S. Penn – 24:38
As a certain someone once said, “New technology does not solve all the problems.”
Katie Robbert – 24:42
It sure does not. If anything, it introduces more of the same. It just sort of amplifies the problems—the breakdowns, I should say—in your internal processes. As you introduce more and more sophisticated technology, if your foundation isn’t strong, if it’s not solid, if your processes are not airtight, this new technology is going to expose all of that. You’re going to very quickly see all of the cracks in your foundation, and you won’t—you’ll be basically just chasing all of those cracks, trying to cement them up, but you’ll never really get to the point where your foundation is solid again.
Christopher S. Penn – 25:24
Exactly. So, to summarize, local AI—good idea for privacy, business continuity, sustainability, and cost reduction—for once you start to scale the use of AI beyond copying and pasting into ChatGPT at the trade-off of learning the software, installing and maintaining the software, and the infrastructure around it. So, there are positives and negatives. You know that you need this when you start dealing with stuff like privacy, where you have very sensitive data. You know you need it when you start having business continuity conversations where you’re like, “Yeah, we—this is now part of our secret sauce. And without it, our company’s in a lot of trouble.” If you’re just copying and pasting blog posts into ChatGPT, you don’t need AI. But if it is now part of your secret sauce, you need to have this kind of backup then.
Christopher S. Penn – 26:17
And with it comes a host of all the things that you should be doing to maintain it. And if you are unclear about that, surprise, we do that.
Katie Robbert – 26:26
We do that. And, I think that it’s interesting because people have been calling AI a shiny object, and obviously, it is, and it isn’t. It is in the sense of everybody’s fascinated by it. It isn’t in the sense that it’s not like an NFT or Clubhouse, where it’s a flash in the pan. It’s here to stay. And if you’re not having these kinds of conversations within your organization to say, “Do we need to think longer-term about privacy? Do we need to think longer-term about sustainability, business continuity, cost?”—you need to start having those conversations. And to Chris’s point, those are conversations that we can help you have because it can feel very overwhelming. You may not know where to start, and that’s okay.
Katie Robbert – 27:14
But even just acknowledging that you should have that conversation is a good place to begin.
Christopher S. Penn – 27:19
