## Tracking status

LT

**probe failed**— This endpoint claims logprob support, but our probe could not obtain usable logprobs. (No logprobs returned)
B3IT

**monitoring**— This endpoint is actively monitored through its border inputs.
## 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.
