anthropic/claude-sonnet-4.5 @ claude-on-aws: B3IT change (TV 0.21)

OpenRouter's tracking of the anthropic/claude-sonnet-4.5 endpoint on claude-on-aws recorded a B3IT total-variation level shift of 0.21, with no logprob tracking possible because the endpoint does not return logprobs. The endpoint is under active B3IT monitoring through its border inputs, and OpenRouter has billed $2.61 total since 2026-08-18 across 65,828 queries, including $2.40 for B3IT onboarding, $0.21 for B3IT monitoring, and $0.0011 for vetting.

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.
