A rate is withheld below 0.5 endpoint-years of exposure. | Method | Endpoints | Endpoint-years | Changes | Rate (/endpoint-year) | 95% interval | | --- | --- | --- | --- | --- | --- | | LT | 6 | 0.42 | 0 | — | — | | B3IT | 10 | 0.76 | 4 | 5.27 | 0.11–10.44 | ## Drift by model Every endpoint sail-research 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 | | --- | --- | --- | --- | --- | --- | --- | | fp4 | 6 | — | — | 0 | 4 | 1 | | us | 4 | — | — | 0 | 3 | 0 | | fp8 | 3 | — | — | 0 | 3 | 3 | ##
