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.

Gap register

20 July 2026: No run. This line had not started collecting yet.

21 July 2026: Run set aside. Our prepaid credit ran out partway through, so 20 of the 63 questions came back as billing errors.

22 July 2026: No run. Our prepaid credit with the provider had run out, so all 63 questions came back as billing errors.

8 to 9 August 2026 (2 days): No run. Our prepaid credit with the provider had run out, so all 63 questions came back as billing errors.

10 August 2026: Run set aside. Our prepaid credit ran out partway through, so 43 of the 63 questions came back as billing errors.

11 to 14 August 2026 (4 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.
