Token usage

Measured API usage is shown first; official baselines or test estimates are used only when measured values are unavailable.

Measured token usage3.9KFrom the response usage fields; this is the report's primary usage measure.Test-suite estimate1.8KPrecisely estimated from this test suite when no official baseline is available.Variance assessment118% aboveMeasured token usage is above the estimate; review billing or provider logs.Usage conclusionAbove estimateThis reflects usage observability, not the final billed amount.

Model authenticity score

Review API availability, model identity, response completeness, and other checks separately.
