Ollama gives you a local LLM in under 20 minutes: zero cost per token, full privacy, and unlimited experimentation. Supports macOS, Linux, and Windows.

Download a model with ollama pull llama3. For modest hardware: Mistral 7B or Phi-3 Mini. With 16GB VRAM GPU: Llama 3 8B or Gemma 2 9B. Open WebUI (Docker) adds a ChatGPT-like interface connected to your local models. Ollama exposes an OpenAI-compatible API at localhost:11434 — any client (LangChain, LlamaIndex) works without changes.

Install with: npm install -g ollama && ollama pull llama3 && docker run -d -p 3000:8080 ghcr.io/open-webui/open-webui:main
