What is Ollama?

Ollama runs open-weight language models on your own machine with a single command, then serves them over a local HTTP API. Its library covers Llama, Mistral, Gemma and Qwen variants plus embedding and vision models, and a Modelfile format pins system prompts and sampling settings into a custom variant. Because it exposes an OpenAI-compatible endpoint, existing code and desktop clients can point at localhost instead of a paid service. The trade-off is expected: quality and speed depend on the memory your computer can spare.

FAQ

Which models can I run?

Its library covers many open-weight families, including Llama, Mistral, Gemma and Qwen variants, plus embedding and vision models. Choice depends on memory: small quantised models run on laptops, while larger ones need a workstation with serious video memory.

Is it completely free?

Running models locally costs nothing beyond your hardware and electricity. There is also an optional hosted plan for larger models or machines that cannot handle them, billed separately, so check that page if you need cloud capacity.

Can existing apps use it?

Yes. Ollama serves an HTTP API on your machine, including an OpenAI-compatible endpoint, so many clients and libraries can be pointed at localhost instead of a paid provider with only a base URL change.
