z-ai/glm-5.3-flash @ sail-research/fp8: B3IT change (TV 0.25)

The z-ai/glm-5.3-flash endpoint hosted at sail-research/fp8 is now under active B3IT monitoring after its logprob probe failed to return usable logprobs, according to the tracking dashboard. The endpoint's B3IT detector recorded a total-variation level shift of 0.25, while OpenRouter has billed $0.11 for tracking since 2026-09-04 across 43,017 queries. No detected changes are listed in the dashboard's change table.

Tracking status LT probe failed — This endpoint claims logprob support, but our probe could not obtain usable logprobs. No logprobs returned 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.
