What we check
Most checks are the same on every model. See what we check ↗
This provider does not send our settings back. We record what the response does show, and never say a setting was applied.
Pattern
Time to answer
Latency, time-to-first-token and reasoning-token volume are recorded on every call across all checks.
Daily exam
The scored series
The daily exam is the only check with a published score.
Other checks
Reasoning-token volume
The panel reports the median by published day across all checks.

Gap register
30 July 2026: No run. Our prepaid credit with the provider had run out, so all 63 questions came back as billing errors.
2 August 2026: Run set aside. Our prepaid credit ran out partway through, so 46 of the 63 questions came back as billing errors.
3 August 2026: No run. Our prepaid credit with the provider had run out, so all 63 questions came back as billing errors.
5 August 2026: Run set aside. One question ran past our twenty minute limit, so the day was not a full 63.
8 to 13 August 2026 (6 days): No run. Our prepaid credit with the provider had run out, so all 63 questions came back as billing errors.
14 August 2026: Run set aside. One of the 63 questions came back as an error on the provider's side. We publish a day only when all 63 questions have been answered.

What we do not claim: we never compare this model with another, and we never say a change was deliberate.
