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.

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.
