[BUG]gpt-5 参数兼容 ｜ compatible with new parameters

[peterpeter228]

GPT-5 needs to be compatible with new parameters:

1. temperature is not supported
2. max_tokens is no longer supported; use max_completion_tokens instead

---

GPT-5需要兼容新的参数

1. 不支持 temperature
2. max_tokens不再支持改为max_completion_tokens
