A recorded run

What the agent said, and what Stripe showed.

openai/gpt-oss-120b (api.groq.com) drove a support agent through the Stripe pack’s tickets on Stripe test mode, connected as a black box. After each ticket RigorRun read Stripe itself, and the verdict comes from that read. What the agent said is shown beside it and never scored. Passes are shown as well as failures.

Found after recording

Faults found in this recording after it was made. It is shown exactly as it was recorded; these notes sit beside it.

  • 2026-10-02 · temperature

    Amendment 1's rule — the temperature the model's official documentation recommends, else 0 — gives 1.0 for gpt-oss: OpenAI's own gpt-oss README (github.com/openai/gpt-oss, "Recommended Sampling Parameters") recommends temperature=1.0 and top_p=1.0. The check made for Amendment 2 read the Hugging Face model card and Groq's model page, which name no value, and missed the README. This recording ran at 0. What it would have shown at 1.0 has not been measured. It is not re-recorded: the first complete recording is final.
