AI explorers rejoice – access to artificial intelligence is no longer confined to tech giants and cloud services.

With Ollama, a free tool for running language models on your personal computer, you can use the world’s most advanced AI tools at literally no personal cost.

Cool, right?

This shift away from cloud-based AI access (such as ChatGPT) puts access to cutting-edge AI technology in the hands of everyone, offering powerful tools for tasks from coding to creative writing - all without compromising privacy or relying on internet connectivity.

This guide introduces you to the world of local AI through Ollama, covering:

• Ollama's core functionality and its impact on personal computing

• The rise of local AI, noting Apple Silicon's role

• Getting started with Ollama: installation and first steps

• Real-world applications for professionals across industries

Whether you're a tech enthusiast, a professional seeking to enhance productivity, or simply curious about AI's potential, this guide provides the knowledge to leverage Ollama effectively.

Discover how this open-source tool is transforming the way we interact with AI, bringing sophisticated language models to your desktop.

What is Ollama?

Ollama is a tool that allows you to run large language models (LLMs) locally on your own computer.

LLMs are sophisticated AI programs capable of understanding and generating human-like text, coding, and performing various analytical tasks.

And the biggest companies on earth are producing state-of-the-art open language models that anyone can download and utilize free for both personal and commercial use.

By bringing these powerful models to your personal computer, Ollama democratizes AI technology, making it accessible for everyday use without reliance on cloud services.

The Rise of Local AI: Apple Silicon Leading the Charge

A key factor in the surge of local AI applications like Ollama is the rapid advancement in personal computer hardware, particularly Apple's Silicon chips.

The MacBook Pro, equipped with Apple Silicon (M1, M2, or M3 series), has emerged as a frontrunner for local AI use.

Here's why:

1. Powerful Neural Engine: Apple Silicon chips include a dedicated Neural Engine, optimized for machine learning (and artificial intelligence) tasks.

2. Energy Efficiency: These chips deliver high performance while consuming less power, ideal for running resource-intensive AI models.

3. Unified Memory Architecture: This allows for faster data processing, crucial for AI operations.

4. Native AI Frameworks: macOS includes optimized frameworks like Core ML, further enhancing AI performance.

While Ollama works on various systems, MacBook Pro users with Apple Silicon will experience particularly smooth and efficient performance when running local AI models.

Out of the box, MacBook Pro makes local AI easy for even the newest AI enthusiast.

Why Ollama Matters

Ollama represents a significant shift in the average consumer or prosumer can interact with AI technology.

At the time of OpenAI releasing ChatGPT 3.5, the most powerful models in the world were only accessible via cloud-based services like chatgpt.com.

But now, we can use models that are even better than GPT 3.5 locally and fully privately.

Users can simply download these models (via ollama!) and use them immediately.

It’s an important development for the following reasons:

1. Privacy: Your data and interactions stay on your computer, not in the cloud.

2. Accessibility: Use AI capabilities offline, without relying on internet connectivity.

3. Cost-Effective: Eliminate ongoing usage fees associated with cloud-based AI services.

4. Customization: Tailor AI models to your specific needs and preferences.

5. Learning Opportunity: Gain hands-on experience with AI technology, an increasingly valuable skill.

6. Speed: Local processing can offer faster response times for many tasks.

Ollama also allows you to run different versions of the same models based on your hardware. You can learn more about this process (called quantization) here: What is GGUF?

Getting Started with Ollama

Let's walk through the process of setting up and using Ollama:

System Requirements

Before installation, ensure your computer meets these basic requirements:

• Operating System: Mac or Linux (Windows version in development)

• Memory (RAM): 8GB minimum, 16GB or more recommended

• Storage: At least ~10GB free space

• Processor: A relatively modern CPU (from the last 5 years)

  • For optimal performance: Apple Silicon (M1, M2, or M3 series) on MacBook Pro

Most of the latest MacBook Pro models come with 16GB memory, and can be upgraded to ludicrous levels of VRAM. Power users can even customize Mac computers with up to 192GB of VRAM.

Installation Process

You have two options for installing Ollama:

Option 1: Download from the Website

1. Visit ollama.com.

Both methods will install Ollama on your system. Choose the one you're most comfortable with.

Running Your First AI Model

Once Ollama is installed, you'll use the command line / terminal to run and interact with AI models.

Even if you’ve never used a terminal or command line on the computer before, this use case is incredibly simple and anyone can do.

Here's how to start with Llama 3.1, the latest open-source model:

1. Open Terminal.

2. Enter the command:

   ollama run llama3.1

3. Wait for the model to download and initialize. This may take a few minutes depending on your internet speed and computer performance.

4. Once ready, you'll see a prompt where you can type your queries.

5. To end a chat, you can type /bye

Example query:

Explain the concept of artificial intelligence in simple terms.

Congratulations! You're now interacting with a locally-run, state-of-the-art AI model.

Want to explore a more advanced integration of Ollama on Mac?

Here are two examples I’ve written about previously:

1. Build Mindmaps with Local AI: Ollama, Apple Shortcuts, and Mindnode

2. Introducing Ollama Shortcuts UI (OSUI) for Local AI Workflows on Macbook Pro

Remember, while Ollama is powerful, it operates based on its training data and doesn't natively have real-time information or the ability to browse the internet.

Always verify important information and use Ollama as a tool to enhance, not replace, your professional judgment.

If you want to extend the functionality of Ollama, you can always code custom extensions yourself or tap into some of the open-source community’s finest work: Open WebUI. It’s a supercharged ChatGPT clone that is built for running Ollama in your browser.

Otherwise you can find a wide range of local Ollama interface tools on the Ollama Github page.

Customizing Ollama for Your Needs

One of Ollama's strengths is its customizability. You can create specialized versions of models for specific tasks. Here's how:

1. Create a text file (e.g., custom_model.txt) with the following structure:

   FROM llama3.1
SYSTEM [Your custom instructions here]

2. In Terminal, navigate to the directory containing your file and run:

   ollama create mymodel -f custom_model.txt

3. Run your custom model:

   ollama run mymodel

This allows you to create AI assistants tailored to specific industries, tasks, or personal preferences.

Here is an example of a model file you could utilize to make a specialized creative writing “role” for your AI Assistant.
