Providers and Models

Chatter supports Gemini and any Ollama model you have locally.

Gemini

Gemini requires an API key from Google AI Studio. Chatter defaults to the gemini-2.5-flash model, but you can select other Gemini models with --model or /model in the UI.

Ollama

Install Ollama and run ollama serve. Chatter connects to http://localhost:11434 unless you override the endpoint via configuration. Once Ollama is running, pull any supported model, for example:

ollama pull llama3.1
chatter --provider ollama --model llama3.1

Tool calls are available in Ollama mode, enabling local workflows that need filesystem access coupled with language model reasoning.
