z-ai/glm-5.3-flash @ coreweave/nvfp4: B3IT change (TV 0.30)

OpenRouter's tracking page for the z-ai/glm-5.3-flash endpoint hosted on coreweave/nvfp4 reports a B3IT change with a total-variation distance of 0.30, while the endpoint's logprob probe failed with an HTTP 400 error because Dynamo's SGLang backend does not currently support logprobs >= 1 due to O(N) per-position detokenization. OpenRouter has billed $0.16 to date for tracking the endpoint since 2026-09-17, including $0.11 in the last 30 days across 70,354 queries, with B3IT onboarding at $0.149 and B3IT monitoring at $0.016. The page lists no detected changes in its changes table and shows the endpoint under active monitoring through its border inputs.

Tracking status LT probe failed — This endpoint claims logprob support, but our probe could not obtain usable logprobs. HTTP 400: ValueError: Dynamo's SGLang backend does not currently support logprobs = 1 due to an O N per-position detokenization… 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. Hover a day on either lane, a change mark or an epoch line to read the data behind it.
