Ollama
The simplest way to download and run open-weight models locally, with one command.
Ollama makes running an open model feel like installing an app: one command pulls the weights and serves them behind a local, OpenAI-compatible API. It manages models, quantisation, and the runtime for you.
That low friction is why it is the usual on-ramp to local models, for a developer's laptop, a prototype, or a modest internal deployment.
Where it fits
The fastest way to get a local model running for development, demos, or a small-scale internal tool.
Where it does not fit
Not built for high-throughput, multi-GPU production serving: that is the job of a dedicated inference engine.

LocalAI Local model runtime
A fit when you want one self-hosted, OpenAI-compatible endpoint covering text, images, and audio.
-
llama.cpp Inference runtime
A fit when models must run on constrained or CPU-only hardware, or when you want a tiny, dependency-light runtime.
