A rate is withheld below 0.5 endpoint-years of exposure. | Method | Endpoints | Endpoint-years | Changes | Rate (/endpoint-year) | 95% interval | | --- | --- | --- | --- | --- | --- | | LT | 9 | 0.68 | 0 | 0.00 | 0.00–4.44 | | B3IT | 9 | 0.59 | 3 | 5.07 | 0.00–10.81 | ## Drift by model Every endpoint wafer 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 | | --- | --- | --- | --- | --- | --- | --- | | — | 7 | — | — | 0 | 5 | 3 | | fp4 | 4 | — | — | 0 | 3 | 0 | | fast | 2 | — | — | 0 | 1 | 0 | | fp8 | 1 | — | — | 0 | 0 | 0 | ##
