anthropic/claude-sonnet-4.6 @ claude-on-aws: B3IT change (TV 0.24)

OpenRouter has recorded $1.81 in total tracking spend on the anthropic/claude-sonnet-4.6 @ claude-on-aws endpoint since 2026-08-18, across 45,628 queries, with B3IT onboarding accounting for $1.5988 and B3IT monitoring for $0.2112 of that total. The endpoint is actively monitored through its border inputs, but no logprob tracking is possible because it does not return logprobs, and the detected-changes table lists no level shifts. B3IT, which measures total-variation distance of border-input votes on a 0–1 scale, is the signal used to track drift from the endpoint's reference period.

Tracking status LT no logprobs — This endpoint does not return logprobs, so logprob tracking is impossible. 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.
