Hard coded AI model (gpt-5-mini)

Operating System

Distribution Method

Describe the issue

I set up AI with but config ai, but after setting up Anthropic with bring-your-own API key and Anthropic model (claude-haiku-5-5), running but branch show <branch-name> --ai showed the following error: Error: Anthropic API error (404 Not Found): {"type":"error","error":{"type":"not_found_error","message":"model: gpt-5-mini"},"request_id":"req_id"}

It seems that even though I specified Anthropic model, GitButler used ChatGPT model which I didn't even set up (I checked my set up with but config ai show).

How to reproduce (Optional)

1. but config ai (Set up with Anthropic with bring your own API key and Anthropic model)
2. but branch show --ai

Expected behavior (Optional)

No response
