deepseek/deepseek-v4.1-flash @ open-inference/fp4: B3IT change (TV 0.23)

OpenRouter's tracking dashboard for the deepseek/deepseek-v4.1-flash endpoint on open-inference/fp4 reports a B3IT (border-input) change with a total-variation distance of 0.23, while log-probability tracking is unavailable because the endpoint does not return logprobs. The endpoint is under active monitoring through its border inputs, and OpenRouter has billed $0.063 in total tracking spend since 2026-09-23, including $0.044 over the last 30 days across 66,006 queries. No dated change events appear in the detected-changes table, and the dashboard gives no explanation for the 0.23 B3IT shift.

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.
