z-ai/glm-5.3 @ sail-research/fp8: B3IT change (TV 0.23)

OpenRouter's tracking of the z-ai/glm-5.3 endpoint at sail-research/fp8 recorded a B3IT total-variation level shift of 0.23, while the endpoint's LT logprob probe failed because no usable logprobs were returned despite the endpoint claiming logprob support. B3IT onboarding accounted for 99.8594% of the $0.91 billed since 2026-09-02, with B3IT monitoring at 0.0546% and vetting at less than 1%, across 40,339 queries.

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.
