What we check
Most checks are the same on every model. See what we check ↗
On every call the provider sends our settings back with the answer. We check them against what we sent.
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.

Real sealed run · 11 to 15 Jul 2026 · original published aggregates
This dated run predates the current count format. Refusals were not separated in its published aggregates, so the original chart remains intact and separate from the current dated run.
Gap register
21 to 22 July 2026 (2 days): No run. Our prepaid credit with the provider had run out, so all 63 questions came back as billing errors.
23 July 2026: Run set aside. One answer arrived incomplete, so the day was not a full 63.
26 July 2026: Run set aside. Our prepaid credit ran out partway through, so 12 of the 63 questions came back as billing errors.
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.
What we do not claim: we never compare this model with another, and we never say a change was deliberate.
