deepseek/deepseek-v4.1-flash @ sail-research/fp4: B3IT change (TV 0.37)

Sail Research retired B3IT monitoring for the deepseek/deepseek-v4.1-flash endpoint on the fp4 provider as of 2026-10-03, citing insufficient border inputs, while LT tracking remains active. The endpoint's total tracked spend since 2026-09-19 is $0.045 across 32,589 queries, with B3IT onboarding accounting for $0.0449, B3IT monitoring $0.0017, LT $0.0001, and vetting $0.000016. No detected changes with level shifts are listed for the endpoint.

Tracking status #

LT

tracked— This endpoint is actively tracked. B3IT

retired · no bis— Monitoring was retired: we could not find enough border inputs for this endpoint. (since 2026-10-03)

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.
