What it is
Ollama is a local model runtime for people who want repeatable commands, local API access, and a clean path into tools such as Open WebUI, coding assistants, and scripts.
When to use it
- You are comfortable with a terminal or want a runtime other tools can call.
- You want repeatable model pulls and a simple local API.
- You expect to connect a web UI, editor, or automation layer later.
Setup path
Install runtime → pull model → run API
- Install Ollama for your operating system.
- Pull one starter model from the Ollama library.
- Run a local prompt, then connect a UI only if the workflow needs one.
Local & privacy implications
- Prompts run locally against the model you pulled.
- Model downloads and library access are external network actions.
- API access is powerful; expose it only to trusted local tools.
