那边说是 CPA 的实现问题，我不太确定，姑且这边也同步一份

你需要把报错的请求日志发上来看一下，单看错误信息无法判断错误的源头。

不太好触发，我多用用看，捕捉到了再post

Hi, I am experiencing this exact issue with the 400 Invalid Argument error using the claude-opus-4-6-thinking model.

I managed to capture the full request log. It seems the issue is triggered when sending a request with Tools/Function definitions (via Vercel AI SDK/OpenAI compatible endpoint). The model seems to reject the arguments when tools are present.

Here is the relevant part of my log:

JSON
=== REQUEST INFO ===
Version: 6.8.8
URL: /v1/chat/completions
Method: POST

=== REQUEST BODY SAMPLE ===
{
"model": "claude-opus-4-6-thinking",
"max_tokens": 128000,
"messages": [...],
"tools": [
{
"type": "function",
"function": { "name": "Task", ... }
},
... (11 tools in total)
]
}

=== API RESPONSE ===
{
"error": {
"code": 400,
"message": "Request contains an invalid argument.",
"status": "INVALID_ARGUMENT"
}
}
Hope this helps identify the source!
