GitHub Copilot is also counting the supposed free gpt-5-mini in the premium-request usage. #173
Description
After I installed copilot-api v0.7.0 (http://192.168.50.1:4141), I called it with opencode using gpt-5-mini. After using it for some time, I checked the copilot usage in vs code and found that the premium request usage was continuously increasing. According to the description on https://github.com/features/copilot/plans, the pro plan has unlimited usage rights for gpt-5-mini, and I am on the pro plan. How can I find the cause of this issue?
By the way, I called MCP through LLM, not sure if this behavior is related to the problem.

@jackywu Are you using opencode? Refer to this configuration #167 (comment) . "npm": "@ai-sdk/openai-compatible" does not support model reasoning functionality; you need to use the message-api, which supports reasoning for gpt/claude/gemini.
