Apple's Siri 2.0 is slated for a spring release with iOS 26.4, marking a pivotal shift for its AI platform. This update is the first step in a broader overhaul, with 2026 positioned as the most significant year for Apple Intelligence since its 2024 debut. The new Siri promises a more personalized experience.

The foundation for this overhaul is a new multi-year partnership with Google. Apple will base its next-generation Apple Foundation Models on Google's Gemini technology and cloud infrastructure. This represents a major pivot for Apple, which previously relied on its own models, and will power future AI features beyond just Siri.

Initial Siri upgrades will arrive this spring, but deeper capabilities like conversation memory and proactive suggestions may be announced at Apple's June developer conference. More substantial changes are expected with iOS 27, rumored to include an AI web search tool and a Health-focused AI agent. The Google deal aims to accelerate these future features.
