google/gemini-3.1-pro-preview @ google-ai-studio/flex: B3IT change (TV 0.28)

OpenRouter's tracking of the google/gemini-3.1-pro-preview endpoint on google-ai-studio/flex recorded a B3IT total-variation shift of 0.28, with no logprob tracking possible because the endpoint does not return logprobs. The endpoint is actively monitored through its border inputs, and OpenRouter has billed $2.87 total since 2026-07-18, including $1.72 over the last 30 days across 75,571 queries. No detected changes with level shifts are listed in the tracking data.

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.
