Ollama is a local AI runtime that makes it easier to pull and run supported models on your machine. It is commonly used by developers who prefer a command-line workflow or local API.
In practice
Apps can connect to Ollama to send prompts to local models. This makes it useful for prototypes, local coding helpers, private experiments, and offline-friendly workflows.
What to watch
Model quality and speed depend on your hardware and the model you choose. You should also check model licenses before commercial use.
