Apple Integrates Gemini Into Siri With iOS 26.4: The First Time Siri Has Felt Smart in Years

Apple is shipping Gemini-powered Siri as part of iOS 26.4, expected to roll out to users the week of April 26. This is the first consumer-facing version of Siri that runs on a frontier AI model — in this case, Google's Gemini — instead of Apple's own voice assistant backend. The impact on everyday use is significant. Gemini brings two capabilities that Siri has never had: deep context handling across a conversation, and tool use. Context handling means Siri can now remember what you said three messages ago and respond coherently. If you ask "What's the weather this weekend?" and then follow up with "What should I pack?", it understands the connection without you repeating yourself. Tool use means Siri can take actions in apps: setting calendar events, drafting messages, searching emails, and pulling up specific documents — all from natural language requests in the same conversation. Apple's own AI features (Writing Tools, Image Playground, and on-device summaries) remain unchanged. Gemini is specifically powering the conversational assistant layer — the part you talk to. Privacy protections: Apple confirmed that Siri queries routed to Gemini follow Google's enterprise privacy commitments, with no training on user conversations by default. This is a notable moment: Apple built the world's most popular AI assistant, watched it fall behind, and chose to partner rather than compete on the model layer. For the hundreds of millions of iPhone users who gave up on Siri years ago, iOS 26.4 is worth trying again.
