Model: [z-ai/glm-4.5](https://www.trackllm.net/models/z-ai2fglm-4.5.md) · Served by: [Chutes](https://www.trackllm.net/providers/chutes.md) (fp8) · Organization: [z-ai](https://www.trackllm.net/orgs/z-ai.md) · Methods: `LT`

glm-4.5 is served by 2 providers (see the model page).
chutes serves 85 models (see the provider page).

## Tracking status

- **LT** — stalled: We tracked this endpoint's logprobs, but its recent queries all failed, so tracking stopped.
- **B3IT** — pending: This endpoint has not been evaluated for tracking yet.

## 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.

## Methods

- **LT — logprob tracking.** Primary signal where the provider returns logprobs. The drift is the mean absolute change in the returned tokens' log-probabilities versus the reference period (nats). A detected changepoint is published once the level shift across it — mean drift over the 7 days after minus the 7 days before — reaches 0.1 nats; that shift is the magnitude shown.
- **B3IT — border inputs.** Black-box fallback for endpoints that hide logprobs. Tracks how far the top-token votes on a ranked set of near-tie prompts have moved from the reference distribution (total variation, 0–1).
