openai/gpt-4o-mini @ openai: B3IT change (TV 0.33)

A tracking dashboard for the openai/gpt-4o-mini endpoint on OpenRouter recorded a B3IT change with a total-variation distance of 0.33, while the endpoint's log-probability drift (LT) and border-input vote drift (B3IT) are both measured against a reference period. Tracking spend since 2026-06-23 totals $0.15, with $0.084 in the last 30 days across 84,052 queries, broken down as $0.1172 for B3IT onboarding, $0.03725 for B3IT monitoring, $0.00483 for LT and $0.00031 for vetting. The page lists no detected changes in its changes table, so no dated level shift is reported.

Tracking status LT tracked — This endpoint is actively tracked. 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.
