What is Ollama?

Editorial review
Ollama makes running large language models on your local machine as easy as running a Docker container. With a single command, you can download and run models like advanced open-source models, and dozens more. Ollama handles model management, quantization, and provides an OpenAI-compatible API, making it trivial to swap cloud AI for local inference. The project has seen significant popularity among developers who want privacy, cost savings, or offline capabilities. Ollama supports both CPU and GPU inference (including Apple Silicon), and the growing model library includes everything from tiny parameter models to massive models.

How Ollama Compares to Competitors

Ollama is free versus nearly all proprietary API services that charge per token or subscription, making it far more affordable for local use. It competes with other open source tools like LocalAI and LM Studio, which also offer free local inference, but Ollama's one-command setup and broad model support give it a strong value edge for simplicity.
