What Changed
Added a configurable model setting for git text generation (commit messages, PR descriptions, branch names). Previously, git text generation used a hardcoded default. Now users can select a specific model in settings.

#1165
Users running expensive reasoning models (e.g., gpt-5.2) as their main chat model shouldn't have those same heavy models used for quick git operations like generating commit messages. This decouples the chat model from the git text generation model, allowing faster/cheaper models for routine git operations while keeping the powerful model for complex conversations.
The default is set to
gpt-5.4-minias a lightweight, cost-effective option that's still capable of writing good commit messages and PR descriptions.UI Changes
Added a new "Git Text Generation Model" setting in the Settings page with:
