The B3IT detector recorded a total-variation level shift of 0.61, and OpenRouter billed $0.10 total for tracking the endpoint across 66,472 queries since 2026-08-27, split into B3IT onboarding ($0.09694), B3IT monitoring ($0.00616) and vetting ($0.000049).", "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 · reinit timeout**— Monitoring was retired: re-initialization after a detected change repeatedly ran out of time. (since 2026-09-17)\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). 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.\n\nHover a day on either lane, a change mark or an epoch line to read the data behind it.\n\n## Detected changes\n\n| Date | Method | Level shift | \n|---|---|---|\n\n## Spend\n\nwhat OpenRouter billed for tracking this endpoint.
