What's My AIMeasured browser confidence matrix, refreshed from cohort telemetry.
GuideMeasured cohorts

guide

Browser support now follows measured cohort evidence instead of static browser copy.

The matrix below groups completed benchmark cohorts by browser, browser version, device class, GPU family, and accelerator path. Confidence drops automatically when a cohort goes stale or stays on a fallback path.

How the fallback works

Full WebGPU cohorts can earn the highest confidence only after repeated measured runs land on the strongest accelerator path.

Degraded WebGPU, WebGL-only, and no-accelerator cohorts stay capped lower even when the raw score looks good.

Any cohort that stops refreshing inside the weekly window is automatically downgraded until newer runs arrive.
