| Best for | Developers, automation, always-on private AI |
Why it's the backbone of local LLMs
Ollama collapsed the hardest parts of local AI — quant selection, GPU detection, serving — into ollama run <model>. That's why its downloads grew ~520× in three years and why nearly every local-AI integration you'll meet assumes it's there, listening on port 11434. On our rig it runs as permanent infrastructure: editors, scripts and agents all talk to the same local endpoint.
The honest limits: you'll live in a terminal (or add a front-end like Open WebUI), the automatic GPU offload occasionally fumbles borderline model/VRAM fits that LM Studio's manual slider handles, and model quality is capped by your card — the fit table is in our GPU guide.

Frequently asked questions
▸What is Ollama?
A free, open-source runtime that downloads, manages and serves LLMs on your own machine behind an OpenAI-compatible local API — one command from install to chatting.
▸What are Ollama's real limits?
Your VRAM decides model quality, the CLI-first workflow isn't for everyone, and fine-grained GPU-offload control is weaker than LM Studio's manual slider.
