I’ve run the test many times and it now passes consistently. The earlier intermittent failures were likely caused by reasoning hallucinations from gpt-oss-20b. |

Pull request overview
This PR fixes websearch E2E tests to prevent reasoning token loops by making the tests more deterministic and constraining response generation. The changes apply uniform adjustments across four test files covering both responses and chat completions API endpoints.
Key changes:
- Reduced temperature from 0.2 to 0.01 for more deterministic outputs
- Added explicit instruction "Answer in 10 words maximum and do not reason" to prevent lengthy reasoning loops
- Removed
max_output_tokensparameter fromtest_responses_http.py
