### 🐛 Bug Description

因为我是通过oneapi，把chatgpt nextweb的openai GPT模型重定向成claude3.5 来使用，会遇到之前解决过的claude角色bug。
能不能让dockercompose 的yml 使用openai 形式的key和url同时可以使用claude3.5模型以及他特殊的角色管理，谢谢

Start with the Docker Compose YAML and the OpenAI-compatible request path used for Claude 3.5, reproducing the reported `Unexpected role "system"` response on version 2.13.1. Done means the OpenAI-style key and URL work with Claude's role handling; the payload names no tests or more specific files to inspect.
