## Tracking status

- **LT** — no logprobs: This endpoint does not return logprobs, so logprob tracking is impossible.
- **B3IT** — not selected: This endpoint vetted fine, but the selection budget went to more popular models.

## Methods

- **LT — logprob tracking.** Primary signal where the provider returns logprobs. The drift is the mean absolute change in the returned tokens' log-probabilities versus the reference period (nats). A detected changepoint is published once the level shift across it — mean drift over the 7 days after minus the 7 days before — reaches 0.1 nats; that shift is the magnitude shown.
- **B3IT — border inputs.** Black-box fallback for endpoints that hide logprobs. Tracks how far the top-token votes on a ranked set of near-tie prompts have moved from the reference distribution (total variation, 0–1).
