Model: [nvidia/nemotron-3-super-120b-a12b:free](https://www.trackllm.net/models/nvidia2fnemotron-3-super-120b-a12b3afree.md) · Served by: NVIDIA · Organization: [nvidia](https://www.trackllm.net/orgs/nvidia.md) · Methods: none (free_excluded)

## Tracking status

- **LT** — no logprobs: This endpoint does not return logprobs, so logprob tracking is impossible.
- **B3IT** — free excluded: Free endpoints are excluded from tracking: their routing and rate limits are too unstable.

## Endpoint details

From the OpenRouter catalog snapshot.

## 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).
