When does this happen?
IF Reusing the same tool function name in consecutive POST requests to /v1/chat/completions causes the server to hang with infinite token generation for the GPT-OSS-120B model.
How others solved it
THEN Ensure each tool call request uses a unique function name to avoid the infinite generation loop. Alternatively, downgrade to vllm version 10.2.0 where the bug is not present, or use a different model (e.g., Mistral, Qwen) which are unaffected.
curl -X POST http://localhost:8000/v1/chat/completions \
-H "Authorization: Bearer ${VLLM_API_KEY}" \
-H "Content-Type: application/json" \
-d '{
"model": "openai/gpt-oss-120b",
"messages": [{"role": "user", "content": "Hi"}],
"tools": [{"type": "function", "function": {"name": "unique_name_per_request", "description": "...", "parameters": {...}}}]
