z-ai/glm-5.3-flash @ cloudflare: B3IT change (TV 0.21)

OpenRouter's tracking page for the z-ai/glm-5.3-flash endpoint on Cloudflare reports a B3IT total-variation level shift of 0.21, with the endpoint under active monitoring through its border inputs. The LT logprob probe failed because the endpoint claims logprob support but returned no usable logprobs. Tracking spend since 2026-08-27 totals $0.096 across 58,329 queries, of which B3IT onboarding accounts for $0.0909 and B3IT monitoring $0.0059.

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.
