Token usage

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

Measured token usage36.8KFrom the response usage fields; this is the report's primary usage measure.Test-suite estimate73.3KPrecisely estimated from this test suite when no official baseline is available.Variance assessment50% belowMeasured token usage is below the estimate, possibly due to tokenizer, compression, or usage-reporting differences.Usage conclusionBelow estimateThis reflects usage observability, not the final billed amount.

Token cache usage test

Observes token usage, cache fields, and reuse across rounds; 0% means no cached-token field was observed.

Tested 5 times

Observed cache share75.7%

Low cache share

Cached tokens were observed, but the share is low. Review API parameters, context reuse, and billing methodology.

Long-context test

Shows stable responses at different context lengths and the model center reference window.
