deepseek/deepseek-v4-flash @ atlas-cloud/fp4: B3IT change (TV 0.55)

OpenRouter's tracking dashboard shows the deepseek/deepseek-v4-flash endpoint at atlas-cloud/fp4 recorded a B3IT total-variation level shift of 0.55, while its LT logprob tracking remains impossible because the endpoint returns no logprobs. B3IT monitoring was retired as of 2026-09-03 because a single query costs more than the per-query guard allows, and total spend on tracking the endpoint since 2026-07-06 stands at $0.43 across 77,629 queries, including $0.051 in the last 30 days.

Tracking status LT no logprobs — This endpoint does not return logprobs, so logprob tracking is impossible. B3IT retired · too expensive — Monitoring was retired: a single query costs more than our per-query guard allows. since 2026-09-03 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.
