34 endpoints across 15 models and 5 serving variants, monitored 2025-06-25 – 2026-09-01. 2 changes detected across 2 endpoints.

## Drift rate

Detected changes per endpoint-year of monitoring, with a 95% Poisson interval. A rate is withheld below 0.5 endpoint-years of exposure.

| Method | Endpoints | Endpoint-years | Changes | Rate (/endpoint-year) | 95% interval |
| --- | --- | --- | --- | --- | --- |
| LT | 34 | 4.77 | 2 | 0.42 | 0.00–1.00 |
| B3IT | 0 | 0.0 | 0 | — | — |

## Drift by model

Every endpoint xai serves. Each endpoint's full drift series and detected changes are in the JSON above.

## Monitoring & changes over time

Endpoints under monitoring each month (the exposure the rate divides by) are in the JSON above under `months` and `variants[].monitoring`.

## Serving variants

A provider's quantizations are separate serving stacks and drift separately.

| Variant | Endpoints | LT rate | LT 95% interval | LT changes | B3IT endpoints | B3IT changes |
| --- | --- | --- | --- | --- | --- | --- |
| — | 15 | 0.39 | 0.00–1.15 | 1 | 0 | 0 |
| priority | 5 | — | — | 0 | 0 | 0 |
| zdr | 5 | — | — | 0 | 0 | 0 |
| zdr/priority | 5 | — | — | 1 | 0 | 0 |
| fast | 4 | 0.00 | 0.00–3.89 | 0 | 0 | 0 |
