Bug Description

Hi, I’m running into an issue when using the Xiaomi provider.

Basically when send something to chat I get this error

ERROR: POST https://token-plan-ams.xiaomimimo.com/v1/chat/completions
Caused by:
    0: 400 Bad Request Reason: data:{"error":{"code":"400","message":"Param Incorrect","param":"The reasoning_content in the thinking mode must be passed back to the API.","type":""}}
    1: Invalid Status Code: 400

Steps to Reproduce

1. Configure Xiaomi's provider and choose mimo-V2.5-pro model
2. Send a chat completion request.
3. The request fails with the 400 error above.

Expected Behavior

The chat/request should succeed

Actual Behavior

When sending a chat completion request via the Xiaomi provider, the API returns a 400 Bad Request with:

‎`{"error":{"code":"400","message":"Param Incorrect","param":"The reasoning_content in the thinking mode must be passed back to the API.","type":""}
