Ollama is an open-source tool for running large language models locally on your machine. It provides a simple CLI and API to download, run, and manage models like Llama, Mistral, Gemma, and Qwen without cloud dependencies.

• One-command model download and execution (ollama run llama3)
• Local inference — no data leaves your machine
• REST API compatible with OpenAI format
• Supports quantized models (GGUF) for consumer hardware

Used by developers for local LLM experimentation, privacy-sensitive applications, offline AI, and as a backend for tools like Open WebUI, Continue, and LangChain.

Completely free and open-source (MIT license). Models are free to download. Hardware cost only (CPU or GPU).
