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.

Vetting is the one-off probe that checks the endpoint's billed cost against its advertised price.

**B3IT (onboarding)** is the initial border-input search;

**B3IT (monitoring)** and

LT are the recurring daily checks.
