Your call: hype or real?

Real = it will matter in daily use. Hype = louder than it is. One vote, and it can’t be changed.

Why it matters

Your data stays on your device, but speed depends on how strong your computer is.

For most people

Try it: switch it on in Opera One if you enjoy testing.

The standard is called WebAI and builds on Opera's earlier work on local models.
It is not tied to one model: it works with systems such as Gemma, and on Macs with Apple's model.
It is an early preview in Opera One, with Opera GX and Opera Neon expected soon.
It can generate text, classify content and understand how pieces of information relate, all in the browser.
It is opt-in; Opera says local AI data stays on the device, though that does not remove every privacy risk.
