z-ai/glm-5.3 @ wafer: B3IT change (TV 0.28)

OpenRouter's monitoring of the z-ai/glm-5.3 endpoint on provider wafer recorded a B3IT total-variation shift of 0.28, while the endpoint's LT logprob probe failed because no logprobs were returned despite the endpoint claiming logprob support. Tracking spend since 2026-09-01 totals $1.06 across 47,163 queries, with $0.58 in the last 30 days, and B3IT onboarding accounting for 0.9186% of spend versus 0.1514% for B3IT monitoring and 0.00061% for vetting.

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.
