Identity verdictInsufficient evidence to determine

ReferenceNo reference under matching conditions

API and capability checks

The basic API call succeeded and returned a recognizable response.

指令跟随：Needs review

API results and model identity are assessed separately. Insufficient evidence does not mean a failed request or a fake model.

Model reference evidence

No reference samples under matching conditions are available for this model.

Model self-identification and individual answers do not establish authenticity. Official references only reflect API behavior at the time of sampling.

Rule version：2026-09-14.v1

Token usage check

Reported usage is used; estimates appear only when none is reported.

Reported usage552.8KThe actual usage reported by the API; this page goes by it.Estimated usage1.7MEstimated from this test's requests.Deviation67% belowThe reported usage is below the estimate, possibly because of how tokens are counted or compressed.Usage checkBelow the estimateFigures are as reported by the API; your bill is authoritative.

Token cache usage test

Several runs in a row to see whether repeated content is billed at the cheaper cache rate; 0% means no cache discount this time.

Total 5 request

Share billed at the cache rate36.3%

Low cache share

Caching was used, but only a little; check your bill to see how much it really saves.

Long-context test

We test how much it can read at once, then compare that with the officially stated length.
