WebGPU works just fine in Safari on my iPhone. It was enabled by default starting with iOS 18.2.

Caniuse says it's still behind a feature flag, are you sure you didn't enable that at some point?

I don’t recall enabling it.

This doesn't load for me on my iPhone or iPad:

Confirmed my M1 iPad Pro iOS 18.4.1 also doesn’t have it enabled. Took a bit of digging in the settings app to discover where to enable feature flags too, confirmed it’s off.

I dug into my iPad and found a feature flag to enable it, hiding in settings/Safari/Advanced.

So definitely not enabled by default yet.

It’s disabled still on my iPhone on iOS 18.4.1. Either it was enabled specifically on 18.2, and then disabled, or you enabled it manually. (Or some other weird thing, like it’s only enabled on iPhone Pros.)
