Most AI chatbots run on big company servers, so every message you send leaves your computer. Ollama lets you run AI models on your own laptop or desktop instead. Your chats stay on your device, it works offline, and the local version is completely free.
Here’s what Ollama is, what you need to run it, and how to get started in minutes.
What Is Ollama?
Ollama is a free, open-source app for Mac, Windows and Linux that downloads open AI models (like Llama, Qwen, Gemma, Mistral and DeepSeek) and runs them on your own computer. You can chat with them in Ollama’s app, use them from the command line, or connect them to other apps through a local API.
Why Run AI Locally?
- Privacy: Your prompts and files never leave your computer.
- Works offline: No internet needed once a model is downloaded.
- No subscription: Local use is free with no usage limits.
- Control: Choose and switch between hundreds of open models.
The trade-off: open models running on a normal laptop are usually less capable than the best cloud assistants like ChatGPT or Claude.
What Computer Do You Need?
| Your computer | What runs well |
|---|---|
| 8 GB RAM | Small models (around 1 to 4 billion parameters) for simple chat |
| 16 GB RAM, or Apple M-series Mac | The 2026 sweet spot: 7 to 14 billion parameter models |
| 32 GB+ RAM or a strong GPU | Larger, more capable models |
Ollama uses Apple Silicon, NVIDIA and many AMD graphics cards to speed things up. Without a good GPU, models still run but more slowly. For a full breakdown, read can your laptop run AI locally?
How to Get Started
- Go to ollama.com and download the app for your system.
- Install it. On Windows, it runs quietly in the background; on Mac, you’ll see a small llama icon in the menu bar.
- Open the Ollama app and pick a model, or type a command like
ollama run llama3.2in a terminal. - Wait for the model to download, then start chatting.
Start with a small model first. If it runs smoothly, try a larger one.
Is Ollama Free?
Yes. Running models on your own computer is free, with no usage caps and no credit card. Ollama also offers optional paid cloud plans, around $20/month (Pro) and $100/month (Max), which let you run very large models on Ollama’s servers when they won’t fit on your computer. You don’t need them for local use. Check Ollama’s pricing page for current details.
