deepseek/deepseek-v4.1-flash @ alibaba: B3IT change (TV 0.34)

OpenRouter's tracking dashboard for the deepseek/deepseek-v4.1-flash endpoint at Alibaba recorded a B3IT total-variation level shift of 0.34, with the endpoint under active monitoring through its border inputs. The endpoint returns no logprobs, so log-probability (LT) tracking is impossible, and OpenRouter has billed $0.11 across 41,933 queries since tracking spend began on 2026-09-14. No detected changes are listed in the change 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.
