Apple Ships Gemini-Powered Siri in iOS 26.4: On-Screen Context, Multi-Step Task Chains

9to5Mac / MacRumors·medium signal

Apple released iOS 26.4 with a completely rebuilt Siri powered by Google Gemini as its core reasoning engine. The new Siri processes on-screen context (reading Safari pages, email confirmations) and chains up to 10 sequential actions from a single request. Gemini handles reasoning and planning while Apple retains control over UI, data routing, and privacy enforcement via Private Cloud Compute. This is the first major consumer deployment of Gemini outside Google's own products.
