z-ai/glm-5.3-flash @ baseten/fp8: B3IT change (TV 0.61)

OpenRouter retired behavioral monitoring of the z-ai/glm-5.3-flash endpoint hosted at baseten/fp8 on 2026-09-17 after re-initialization repeatedly timed out following a detected change, leaving no logprob tracking because the endpoint does not return logprobs. The B3IT detector recorded a total-variation level shift of 0.61, and OpenRouter billed $0.10 total for tracking the endpoint across 66,472 queries since 2026-08-27, split into B3IT onboarding ($0.09694), B3IT monitoring ($0.00616) and vetting ($0.000049).

Tracking status #

LT

no logprobs— This endpoint does not return logprobs, so logprob tracking is impossible. B3IT

retired · reinit timeout— Monitoring was retired: re-initialization after a detected change repeatedly ran out of time. (since 2026-09-17)

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.
