B3IT monitoring was retired as of 2026-09-03 because a single query costs more than the per-query guard allows, and total spend on tracking the endpoint since 2026-07-06 stands at $0.43 across 77,629 queries, including $0.051 in the last 30 days.", "body_md": "## Tracking status\n\nLT\n\n**no logprobs**— This endpoint does not return logprobs, so logprob tracking is impossible.\nB3IT\n\n**retired · too expensive**— Monitoring was retired: a single query costs more than our per-query guard allows. (since 2026-09-03)\n## Drift from baseline\n\nBoth 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).
