# Default Models

This page documents gmuse's default LLM model choices and the rationale.

## Default mapping (economy-focused)

- **openai**: `gpt-4o-mini`
- **anthropic**: `claude-haiku-4-5`
- **cohere**: `command-light`
- **azure**: `gpt-4o-mini`
- **gemini**: `gemini/gemini-flash-lite-latest`

## Rationale

The defaults prefer smaller/light/mini/haiku variants intended to be lower-cost and
lower-latency while still providing reliable instruction-following for short
text generation tasks such as commit message generation. Users can override
these defaults using the `GMUSE_MODEL` environment variable or the `--model`
CLI option for a single invocation.

## Notes

- These defaults may be updated over time as providers introduce newer, more
  cost-efficient variants. If you need higher quality or advanced capabilities
  (e.g., long-form reasoning or large-context agents), specify a stronger
  model via `--model` or config file.
