What’s On My Mind: How To Get Started with Local AI Models

After a post ran wild on LinkedIn, I suppose it’s time to write up how to get started with local AI models. I’ll provide two cautions on this issue of the newsletter. First, it will inherently be more technical than you’re probably used to with generative AI. You and I are used to opening a browser window, logging into the AI tools of our choice, and getting things done. We never have to think about the plumbing and infrastructure that makes those tools possible.

If you’re uncomfortable or unable (due to company IT policies, for example) to do this more technical stuff, then feel free to just relax and read, or skip this issue entirely.

The second caution is about language. There are a lot of confusing terms in this space, so we should do a bit of definition setting. I use several different terms that are somewhat interchangeable, so let’s set the table:

• Local AI: generative AI models that you run on your hardware, from your phone to your own on-premise datacenters. Any environment where you have complete control of the machine that the AI model is running on is local AI.
• Open model/open weights model: generative AI models which are distributed for free online by model makers. These models enable you to run them anywhere, and you don’t have to pay the model maker to make use of it. Some people will mistakenly call this open source models or open source AI, but almost no model makers distribute the training data set itself that would be needed to qualify as truly open source.

These are technically NOT the same thing. Local AI is local to you and your network. Open models can run anywhere. For example, you can run open models in IBM WatsonX.ai, IBM’s generative AI secure cloud. It’s not at all local. You have no control over the machine it’s running on. But for many organizations, especially those running inside IBM’s cloud and needing IBM’s governance technology, it’s a great place to run open weights models.

We should probably talk about WHY you’d want to do this, when services like ChatGPT are so convenient. There are five reasons you might want to use a local AI models over a SaaS AI service:

• Privacy: when you run models on your hardware locally, no data ever leaves your system. You have as much privacy and security as your machine itself. This is a HUGE draw for anyone working with sensitive data.
• Cost: when you run models on your hardware locally, the cost is your operating cost (usually electricity). This is super important for things like R&D where you might be making tons of API calls to a model as part of your development process. Using a cloud provider, this could rack up huge bills before you even have a product to show or sell. Using local models reduces that cost substantially – and might be successful enough that you could justify using a local model even in production.
• Sustainability: the less power you use to operate AI, the more sustainable it is. Yes, there are clearly economies of scale when providers have massive, concentrated compute power, but given that they’re all looking to vacuum up as much electricity as possible, it’s not a terrible stretch of the imagination to realize AI is incredibly resource hungry. Using local models can reduce that power consumption if done well.
• Control: when you run models locally, you have complete control over how they’re configured, far more than any cloud service would let you. This is a double edged sword; you can misconfigure a model to the point where it becomes nonfunctional – but if there are specific things you want a model to do, access to those extra controls can be helpful.
• Reliability: local AI models run on your machine. Once you download them, they’re yours. If OpenAI closed up shop tomorrow, ChatGPT would be gone, but your local AI would continue to function for as long as your computer did.

With these points in mind, let’s dig into the process of HOW to set these things up. If you’re watching the video version of this newsletter, you’ll see some of these examples in greater detail. We need to talk through hardware, models, software, configuration, and use, in that order.

Part 1: Hardware

To run generative AI models on your machine, you need sufficient resources. Generative AI models typically need lots and lots of memory to run well. Your computer has two kinds of memory that are important – regular computer memory (RAM), and graphics memory (VRAM, or video RAM). For generative AI to run well, VRAM is the most important – and the wildest variable.

Today’s gaming PC laptops typically come with 12-16 GB of VRAM, though some high end gaming rigs come with more. Today’s Macs are a different beast – Macs since 2019 (the M-series Macs with names like M1, M2, M3, M4) have shared memory, which means that regular RAM and VRAM are the same thing. There’s a big pool that the computer automatically shares.

This matters a lot because on PCs, you will often need software that can load AI models on both your VRAM and RAM, and when an AI models is running on regular RAM, it is s-l-o-w.

The basic message here is simple: if you’re buying/using PCs, get as much VRAM as you can afford. If you’re buying/using Macs, get as much memory as you can afford. More is always better.

Your computer, somewhere in its settings (it’s been a hot minute since I’ve used a PC but I’d guess either Task Manager or System Preferences will get you where you want to go, and you can probably ask Windows Copilot to just tell you) will tell you how much memory you have to work with. If I remember correctly, both Macs and PCs have an Activity Manager app that tells you the current state of your computer.

Find your memory status, close all your open applications, and make note of how much of each kind of memory you have.

For example, on my MacBook, this is what I see with nothing else running:

You can see that I have about 110 GB of total memory available. We’ll need this information shortly.

Part 2: Models

Once we’ve figured out how much memory is available to us overall, we can start ‘shopping’ for models. I say shopping because we need to find open weights models that suit our needs. On the model repository Hugging Face, there are over 1.6 million different models to pick from. Granted, many of them are purpose built for specific tasks, so we’ll focus on a few big families of models which are currently high-performing.

The three families I recommend for the average business user are:

• Google Gemma
• Meta Llama
• Mistral

In each family, there are different models sizes. You’ll see this listed in the model name, the number of parameters that the model contains. Parameters are how much knowledge and information a model contains. For example, you’ll see things like Google Gemma 3 1B, 4B, 12B, 27B, etc. Those numbers indicate 1 billion parameters, 4 billion parameters, etc.

Generally speaking, more is better BUT there’s a limitation: the bigger a model is in parameters, the more memory it needs to run well. If you pick a model that’s bigger than the memory you have available, it will literally crash your computer by consuming all the memory and grinding your entire computer to a halt.

The tradeoff with smaller parameter models? Parameters are knowledge. The fewer the parameters, the dumber the model is. A model like Google Gemma 1B is coherent but will hallucinate just about everything, making things up because it has almost no background knowledge. A model like Google Gemma 27B is going to be far more fluent and knowledgeable.

It’s important to say that open models in general that you can run on a laptop are going to be far less knowledgeable than the big frontier models we’re used to. ChatGPT’s GPT-4o model is estimated to have trillions of parameters, as is Google Gemini. We’ll talk more about the implications of this in a little while.

Before we dig into choosing specific models, we need to talk about a very confusing aspect of selecting a model: quantization.

Model makers release their models in the highest possible accuracy format. When we interact with those versions of the models, they perform tasks at their highest accuracy level – but they are memory hogs. They eat up memory like crazy and run fairly slowly.

The open weights community will often take a model made by a model maker and perform quantization on it, which is a kind of compression. What it does is it reduces the accuracy of the model, but makes it significantly faster to operate. We can dig into the math of quantization another time, but the cheat sheet version is that we want models that are quantized at 4, 5, or 6 bits. Generally speaking, quantization is a tradeoff between resource usage and accuracy, and 4-6 bit quantization is the sweet spot for most models.

You see this in model names, like gemma-3-27b-q5_k_l. This rather arcane name means Gemma 3 the model, 27 billion parameter version, and 5 bit quantization.

Here’s the fastest cheat sheet I can offer on quantization: in general, use either q4 or q5 models whenever you can.

Then choose a model based on its parameters and your memory. My rule of thumb is: take the number of parameters, double it, and that’s the RAM you‘ll need to have for the model to be useful. I define useful as a model that operates at a reasonable speed (15 tokens/second or so) and has a large enough context window (64K or so) to be useful for most common tasks.

For example, suppose you chose Google Gemma 3 4B, at a q4 or q5 quantization. 4 * 2 = 8, so you’ll need 8 GB of VRAM available to run it well. (Yes, for the more technical folks, there are a ton of nuances here, but we’re trying to get started. Doubling the memory like this accounts for a generous context window and the key/value cache.)

So from part 1, what’s your available VRAM? If you have a 16 GB graphics card, you can safely run an 8B model well, or anything below that number. You could run Google Gemma 3 4B easily. Yes, technically you can run Google Gemma 3 12B, but it’s going to be so slow and with such a small context window (the available short term memory in a chat) that it’s not going to be useful.

On my Mac, I have about 110 GB of memory available, which means I can run any size Gemma model up to its max size of 27B and have it be usable and fast. I could run models up to 55 billion parameters on my current setup.

When we hit up the Hugging Face repository for models, or look at the model catalogs in interfaces, this now gives us a baseline for choosing models.

We can look at the models by family and parameters without also having to take quantization into account beyond the basics, at least for getting started.

Let’s move onto software.

Part 3: Software

Now that we’ve got an understanding of what models we can run, we need to get the necessary software to run them. No one runs an AI model directly; AI models are essentially just gigantic databases of statistics at their core. To make use of a model, we need an interface around it. This is akin to cars; no one drives down the road sitting on an engine block. The engine block is embedded in the car itself, and while the engine block is critical – a car can’t go anywhere without an engine – neither is the engine useful without the car.

For the average person who wants to get started with local AI models, you’ll want to choose an interface that also has the back end server built into it. Think about AI interfaces like you think about the Web, with two major parts, a server and a client.

When you surf the web, your client – the web browser, like Safari or Chrome or Brave – goes out and interfaces with someone else’s web server that contains the web site. Companies like WP Engine have servers – lots of them, big hardware – that serve up software like WordPress and ultimately websites like the Trust Insights website. You need both – a client without a server is useless, and vice versa.

AI models work somewhat similarly. There’s a server that serves up the model, and a client that interfaces with it. When you visit ChatGPT or Claude or Gemini by browser or app, you’re using the client to talk to the AI servers that are running at those big tech companies.

In the local AI model space, there are software packages that bundle both together, that are both client and server. This is what we want to use for getting started with local AI at the most basic level.

There are two software packages I recommend for the average person who’s not super eager to set up servers: AnythingLLM and LM Studio. Both of these are free; the main differences are in functionality. AnythingLLM has a LOT of stuff baked in, like document management, speech recognition, etc. It tries to do a lot and for the most part it succeeds; it also has the basic chat style interface we all know and use.

LM Studio provides the same familiar chat interface as well, but tries to be a more robust server as well as a client. It’s especially good for current M-series Macs as it supports Apple’s MLX AI standard. An MLX version of a model runs 5-8% faster than a non-MLX model.

How do you decide between the two? If you plan on using agents, APIs, or developing code against your local AI, I strongly suggest LM Studio (Or if you have a Mac). If you plan on just using it as an end user consumer, the way you use ChatGPT or Gemini today, then AnythingLLM would be a good choice.

These are standard apps that run on your computer, so install them like you’d install any other piece of software.

Part 4: Configuration

Just as a piece of newly installed software like Microsoft Word needs some configuration or tailoring to make it useful to your specific use case, so too does AI software need some configuration to make it useful.

We first have to decide which model to use. There are a ton of choices. One of the peculiarities of open models is that with so many of them, different models are known to be good at different tasks, and there are a lot of specialized models that are purpose built or tuned for one kind of task. This is a contrast to a tool like Gemini, Claude, or ChatGPT that try and largely succeed at being good at many different kinds of tasks.

Let’s look at a few different model families and what they’re good at.

• Google Gemma 3: Gemma 3 does a very good job of following instructions, especially the 12B and 27B versions. If you have tasks where instruction following (like step by step instructions, workflows, etc.) are important, Gemma 3 will serve you well. Gemma can write but tends to be a bit terse.
• Meta Llama 3.3: While Llama 4 is in market, it’s too large for most consumer hardware. Llama 3.3 is the current version that can run on consumer hardware. Llama 3.3 is a decent fit for nonfiction writing.
• Mistral Small: The Mistral family excels at multilingual work and writing. It’s very capable, especially the current Small version, Small 3 24B, a 24 billion parameters model. Remember you’ll want to have 48 GB of VRAM/memory to get solid use out of it.
• DeepCoder: If you’re using generative AI specifically to write code, DeepCoder is a fantastic model for coding, especially first drafts.

Once you choose a model that is an appropriate size for the memory and resources you have, download it in the app’s interface.

In the main chat window or in the settings, depending on what app you’re using, you’ll want to take a few moments to get acclimated to features as well as possibly mess with some settings. One of the more useful settings to know is a parameter called temperature. You’ll see this in the model settings.

What does temperature do? Fundamentally, temperature controls the level of randomness in the model’s responses. A low temperature means less randomness. A higher temperature means more randomness.

Why would you want to mess with this? Some tasks are very deterministic; you don’t want the model getting too creative. For example, if you asked a model to classify some text in a set of defined categories, you would set a low temperature, like 0.5, to keep it from arbitrarily coming up with new categories.

Other tasks are more probabilistic, like creative writing. Set the temperature too low, and you get incredibly robotic generation. A temperature anywhere from 0.7 to 1.0 will tend to yield more creative writing by allowing the model more freedom to be creative.

For those folks used to an interface like ChatGPT, this might seem unusual. Behind the scenes, services like ChatGPT have the exact same settings and controls; it’s just that those end user models are usually set by the provider and the average consumer has no ability to control them or change them.

Okay, so you’ve got your software installed. You’ve got your model downloaded and installed. You’ve got your settings configured. You’re finally ready to begin using local AI.

Part 5: Usage

Finally, we get to the good part, right? Well, the good part is surprisingly dull: it’s just like every other generative AI large language model you’ve used. There are a couple of twists that are important to know when it comes to open models and local AI.

Remember how we talked about parameter counts, how the more parameters a model has, the better it tends to perform? This is relevant both for instruction following (aka doing what you tell it to do in your prompts) as well as knowledge. More parameters means more encoded knowledge.

But except for really, really big models like Llama 3.1 405B (405 billion parameters), DeepSeek (671 billion parameters), and a handful of others, most local models are going to be effectively under 50 billion parameters. At that scale, models will have some knowledge, but the risks of hallucination are very high.

What that means is that you have to bring more data to the party. Here’s a simple example. If you ask a small model like Gemma 3 4B who the CEO of Trust Insights is, it’ll give a non-sensical answer. If you provide the answer, it’ll recite it perfectly.

Now, you might say (quite correctly) that if we have to provide the answer, what’s the point? Well, now we get into the use cases of generative AI (which you can learn more about in my new course, Generative AI Use Cases for Marketers) and what smaller models are good at.

• Extraction: take data out of other data
• Classification: organize data
• Summarization: make big data into small data
• Rewriting: transform data from one form to another
• Synthesis: take small data and aggregate it into big data
• Question Answering: answer questions about your data or in general
• Generation: make new data

When it comes to local AI, the first 5 use cases here are where it really shines. Given the data, even very small models like Gemma 3 4B can do a very capable job – and they’ll be lightning quick about it as well.

Where they will fall down is on use cases 6 and 7, when we’re asking the models to create new data. For example, asking Gemma 3 for a restaurant recommendation in your area without providing any data is not going to go well. It just doesn’t have enough knowledge. Ask it while providing it a large JSON document of restaurants and their offerings, and it’ll do just fine.

The same is true of generation. Ask it to write, for example, a blog post about B2B marketing without any background data and it’s going to come up with generic slop. There’s just not enough knowledge in any one domain for it to create really unique, compelling content, especially once you’re below about 10 billion parameters. Give it your backlog of newsletters and podcasts as a data store, and chances are it’ll do much better at generating something.

Where these models shine is on repetitive tasks, especially if you can automate them. Remember last week’s newsletter about n8n? A local AI model is going to be a huge cost saver if you can wire a workflow to use it rather than a cloud based service.

Part 6: Wrapping Up

We looked mostly at the how in this issue of the newsletter, and if you have the hardware and tools like LM Studio or AnythingLLM, you’re well positioned to start making use of local AI models.

One final caution on local AI, especially on laptops: using the GPU at full tilt consumes 100% of the energy of the system. Expect your fans to run, and you might even run down the battery – while your laptop is plugged in! All generative AI is incredibly power intensive, so if you’re using generative AI models heavily on your machine, don’t expect your machine to do many other things at the same time unless you’ve got a beast of a machine.

Remember the key reasons to use local models: cost, privacy, flexibility, sustainability, and reliability. State of the art performance is NOT one of the reasons to use them, so if you’re tackling a very complex task that demands state of the art performance, use a big frontier model instead.

I hope this guide gives you a great starting place for generative AI running locally. If you’d like a more strategic tour, watch this talk I gave at the MAICON 2024 conference on open models and local AI. Though there have been a lot of technical and tactical changes, the strategy remains largely the same.
