Model: [aion-labs/aion-rp-llama-3.1-8b](https://www.trackllm.net/models/aion-labs2faion-rp-llama-3.1-8b.md) · Served by: [Aion Labs](https://www.trackllm.net/providers/aion-labs.md) · Organization: [aion-labs](https://www.trackllm.net/orgs/aion-labs.md) · Methods: `B3IT`

aion-rp-llama-3.1-8b is served by 1 provider (see the model page).
aion-labs serves 2 models (see the provider page).

## Tracking status

- **LT** — no logprobs: This endpoint does not return logprobs, so logprob tracking is impossible.
- **B3IT** — retired · delisted: Monitoring was retired: the endpoint dropped out of our B3IT selection (flagships, the most popular models, the cheapest endpoints per provider, within budget) for 30 days. (since 2026-09-25)

## 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).
