Reproducible server_error on /v1/responses with gpt-4.1-mini + web_search tool

Thanks for testing it, @_j good to hear it’s working on your end. I just re-ran my exact failing curl and it now returns 200 as well, so something appears to have changed server-side between my last failing repro (~48 hours ago) and now. Five reproducible 500s across two sessions to zero in the same configuration is a pretty clean before/after.

If anyone from the platform team is reading: would be useful to confirm whether a fix or config change went out for web_search tool orchestration on gpt-4.1-mini in the last 48 hours, just so future readers of this thread know whether to expect a regression. Happy to share the original failing request IDs (also in support case 08421197) if it helps correlate to logs.

Leaving the thread open in case the regression returns.
