Overview
- Reports say Apple is finalizing access to a custom 1.2 trillion‑parameter Gemini model, far larger than Apple’s current cloud model.
- Gemini would power Siri’s summarizer and multi‑step planner, while other capabilities continue to rely on Apple’s own models.
- The Google model would run on Apple’s servers, with sources saying Google would not receive user data.
- The upgraded assistant is expected to debut with iOS 26.4 in spring 2026, and neither company has publicly confirmed the deal.
- Apple tested OpenAI and Anthropic before favoring Google on commercial terms, while pursuing an in‑house ~1 trillion‑parameter cloud model and planning non‑Gemini deployments in China.
