Describe the feature or problem you'd like to solve
Add support for more models such as GPT-5-mini, gemini-3-pro-preview etc.
Proposed solution
Currently, it seems that the ACP mode of copilot ONLY supports the Claude Sonnet 4.5 (default), Claude Sonnet 4, GPT-5 even though the copilot-cli actually supports more. In theory, this will not be a hard feature to implement.
