deepseek/deepseek-v4.1-flash @ baidu/fp8: B3IT change (TV 0.41)

OpenRouter's tracking page for the deepseek/deepseek-v4.1-flash endpoint at baidu/fp8 shows a B3IT border-input change with a total-variation distance of 0.41, while logprob tracking is unavailable because the endpoint returns no logprobs. The endpoint is under active B3IT monitoring, and OpenRouter has billed $0.11 for tracking since 2026-09-29 across 51,659 queries, split between B3IT onboarding ($0.09988), B3IT monitoring ($0.01312) and vetting ($0.000077). No dated level shifts are listed in the detected-changes table.

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.

Vetting is the one-off probe that checks the endpoint's billed cost against its advertised price.

**B3IT (onboarding)** is the initial border-input search;

**B3IT (monitoring)** and

LT are the recurring daily checks.
