Model: [kwaipilot/kat-coder-pro](https://www.trackllm.net/models/kwaipilot2fkat-coder-pro.md) · Served by: [StreamLake](https://www.trackllm.net/providers/streamlake.md) (fp16) · Organization: [kwaipilot](https://www.trackllm.net/orgs/kwaipilot.md) · Methods: `B3IT`

kat-coder-pro is served by 1 provider (see the model page).
streamlake serves 15 models (see the provider page).

## Tracking status

- **LT** — pending: This endpoint has not been evaluated for tracking yet.
- **B3IT** — retired · stalled: Monitoring was retired: the endpoint stopped yielding usable samples. (since 2026-03-30)

## 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.

## Detected changes

No change detected so far.

## 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).
