Siri 2.0 Arrives: Apple Taps Google Gemini for AI Now

• Apple is relaunching Siri with a Gemini-powered overhaul starting in iOS 26.4 this spring.
• A multi-year collaboration with Google will base Apple’s next-generation foundation models on Google’s Gemini and cloud tech.
• Immediate Siri improvements will roll out in stages; memory, proactive features and broader Apple Intelligence upgrades are slated for later (WWDC and iOS 27).

What Apple announced

Apple confirmed a multi-year collaboration with Google that will place Google’s Gemini models and cloud technology at the core of its next-generation Apple Foundation Models. The partnership is designed to power new Apple Intelligence features, including a more personalized Siri.

What to expect in iOS 26.4

Apple plans to introduce the first wave of Siri upgrades in iOS 26.4, arriving this spring. The update is expected to appear first in developer and public betas before a wider release.

These early changes aim to improve responsiveness, context handling, and personalization — but they won’t deliver the full vision of a memory-aware, proactive Siri just yet.

Roadmap beyond the spring update

Reports indicate more advanced capabilities — such as Siri remembering past conversations and offering proactive suggestions tied to your calendar and travel — are planned for announcement at Apple’s annual developer conference (WWDC) in June.

Apple is also expected to continue layering features across iOS 27, where a broader revamp of Apple Intelligence is likely to include AI-powered web search tools, health-focused agents, and a visual/personalized Siri personality.

Why the Gemini tie-up matters

By building its next-generation foundation models on Gemini, Apple shifts from developing everything in-house to combining its device ecosystem with Google’s large language models and cloud infrastructure. As Apple said in the joint statement: “These models will help power future Apple Intelligence features, including a more personalized Siri coming this year.”

The move is strategic: it gives Apple a faster path to modern LLMs while preserving room for Apple-specific fine-tuning and integration across iPhone, iPad, and Mac.

Bottom line

Siri 2.0 in iOS 26.4 is the start, not the finish. Expect visible improvements this spring, but the full promise—memory, proactivity, and deeper Apple Intelligence features—will roll out over 2026 and into iOS 27.

Apple’s Google partnership accelerates that timeline, but patience will be required as engineers refine Gemini-based models for Apple’s privacy and ecosystem requirements.
