Ollama is a lightweight, open-source tool that lets you run powerful large language models (LLMs) locally on your own machine — with a simple CLI, API, and support for macOS, Linux, and Windows.
Purpose
Ollama makes it easy to download, run, and integrate open-source AI models (like Llama, Gemma, DeepSeek, Qwen, and more) directly on your hardware — for privacy-focused, offline, low-latency AI without cloud costs or data sharing.
Key advantages:
- Full privacy & data control — everything stays local
- Offline access and zero ongoing costs
- Super simple setup (one command to install/run models)
- OpenAI-compatible API — works seamlessly with tools like Claude Code, VS Code extensions, LangChain, etc.
- Fast & efficient on consumer GPUs/CPUs (with great multi-GPU support in 2026)
Developers love it as the go-to way to run local AI — feels like having private, customizable ChatGPT/GPT-level power right on your laptop (early 2026).
