## Tracking status

LT

**no logprobs**— This endpoint does not return logprobs, so logprob tracking is impossible.
B3IT

**retired · too expensive**— Monitoring was retired: a single query costs more than our per-query guard allows. (since 2026-09-03)
## Drift from baseline

Both signals measure how far this endpoint's behavior has moved from its **reference period**. LT tracks the average change in the returned tokens' log-probabilities (nats); B3IT tracks the total-variation distance of the border-input votes (0–1). Both should ideally be as close to 0 as possible. Dashed lines mark published changes, labeled with the **level shift** across them: for LT the mean drift over the 7 days after minus the 7 days before; for B3IT the total-variation shift its detector measured.

Hover a day on either lane, a change mark or an epoch line to read the data behind it.

**Vetting** is the one-off probe that checks the endpoint's billed cost against its advertised price.

**B3IT (onboarding)** is the initial border-input search;

**B3IT (monitoring)** and

**LT** are the recurring daily checks.
