Model: [mistralai/devstral-small-2505](https://www.trackllm.net/models/mistralai2fdevstral-small-2505.md) · Served by: [DeepInfra](https://www.trackllm.net/providers/deepinfra.md) (bf16) · Organization: [mistralai](https://www.trackllm.net/orgs/mistralai.md) · Methods: `B3IT`

devstral-small-2505 is served by 3 providers (see the model page).
deepinfra 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 2026-01-15)

## 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).
