Apple to update Siri using Google Gemini AI technology

Apple is reportedly finalizing a landmark deal to integrate a custom version of Google’s Gemini AI model into Siri. According to the original report, "Apple plans big Siri update with help from Google AI", the tech giant aims to leverage Google's massive infrastructure to drive a significant leap in the voice assistant's capabilities.

A Massive Power Boost for Siri

The partnership involves a high-performance model featuring 1.2 trillion parameters—a staggering increase from the 150 billion parameters currently supporting Apple Intelligence. This custom Gemini model will specifically enhance:

• Intelligent Summarization: Faster and more accurate text and data processing.
• Advanced Planning: Improved ability for Siri to handle complex, multi-step tasks.
• Contextual Understanding: Deepening the assistant's grasp of user intent.

Privacy and Implementation

To maintain its strict privacy standards, Apple will run the Gemini model on its own Private Cloud Compute servers. This ensures that user data remains isolated from Google’s systems. Known internally as project "Glenwood", the refreshed Siri is expected to debut with iOS 26.4 in the spring of 2026.

Global Strategy and China

While the Google partnership powers the global rollout, Apple is adapting its strategy for the Chinese market. Since Google services are unavailable there, Apple plans to utilize its own internal models combined with local content filters provided by Alibaba Group to meet regional regulatory requirements.
