### Terminal Traceback & Material to Help Reproduce Bugs | 终端traceback（如有） + 帮助我们复现的测试材料样本（如有）

_No response_

Start with request_llms/bridge_all.py around line 782 and inspect how the AVAIL_LLM_MODELS configuration is converted into the model_info lookup. Reproduce the failure with gpt-4o in the Docker/Hugging Face setup after adding that model, then verify the lookup no longer raises KeyError.
