Run a non-Grok model like Claude or Gemini
models and endpoints
// what it does
Combine --model with a --base-url that serves it to drive a non-Grok model, for example grok --model claude-sonnet-4-20250514 --base-url https://your-endpoint/v1 or grok --model gemini-2.5-pro --base-url .... The key must belong to that endpoint.
// shell
$ grok --model gemini-2.5-pro --base-url https://your-endpoint.example.com/v1$ grok --model claude-sonnet-4-20250514 --base-url https://your-endpoint.example.com/v1// gotcha
Model ids are provider-specific — claude-* and gemini-* only resolve on endpoints that host them, not on api.x.ai. A mismatched model and base URL is the most common cause of a 404 model-not-found error.
