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.

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.
