Overview
Ollama lets you download and run LLMs such as Llama 3.3, DeepSeek-R1, Phi-4, and Gemma 3 on your own hardware with a single command. It exposes an OpenAI-compatible REST API so existing tools integrate without modification. GPU acceleration is supported on NVIDIA, AMD, and Apple Silicon. Distributed as a native binary and Docker image, setup requires no manual dependency management.
Setup and operations guides
Use these practical guides to plan the deployment, security, backups, and recovery work behind this project.
Where it falls short of OpenAI API
- No built-in chat UI; requires a separate front-end like Open-WebUI
- Fine-tuning and model training are not supported; inference only
- Multi-GPU distributed inference is limited compared to commercial inference APIs
- No built-in authentication, rate-limiting, or multi-tenant access control
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
