I personally use Firefox mainly due to extension support so I don't experience this. However, as a developer, the embedded Gemma local model in Chrome is vastly better to be included as a one time download than it is to download an AI model for every site you visit, as AI and especially local AI becomes increasingly more common. It is the same idea that Apple and Android and Windows have with their built-in foundation models in the OS. So in that case I can appreciate what Chrome is doing, as it will be saving a lot of bandwidth over time.

People have asked me what use cases this has, and I've been making little apps with on-device AI such as a calorie estimator and tracker for food, or a page summarizer or translated (the latter of which Firefox actually already has using a local model). Why pay for a cloud model when the user has a perfectly good model themselves?
