Text models
GPT-6 vs. GPT-6.1 Sol: upgrade checks
Compare the two model IDs with the same requests, tools, and limits.
Change one variable
Keep prompts, tool schemas, and output limits fixed when switching model IDs. Test response formatting, tool results, streaming, and usage reporting.
Keep a rollback reference
Record pass rate, latency, and per-request cost for both models. Save the previous model ID and the cases that determine whether the upgrade stays.
