Apple has officially confirmed that its next-generation Siri will rely on a specialized version of Google’s Gemini AI, effectively outsourcing parts of its functionality to one of the tech industry’s most advanced large language models. This move suggests Apple is accelerating efforts to enhance Siri’s capabilities beyond what its in-house models can deliver, particularly in complex decision-making and summarization tasks.
The integration comes as part of a broader overhaul of Siri under Apple Intelligence, a framework designed to make the assistant more agentic and context-aware. While Apple has historically emphasized on-device processing for privacy reasons, the new approach indicates a pragmatic shift toward leveraging external AI infrastructure—at least in cloud-based operations—to improve performance.
The custom Gemini model, which reportedly boasts 1.2 trillion parameters, will serve as the backbone for Siri’s query planner and summarizer functions. This means that when users ask Siri to summarize a long article or draft an email, the assistant will tap into Google’s AI rather than rely solely on Apple’s smaller, on-device foundation models. The knowledge search system, which handles general trivia and factual queries, remains under Apple’s control.
This isn’t the first time Apple has turned to external AI partners. Earlier this year, it integrated OpenAI’s ChatGPT into Siri for tasks like summarizing web content or generating creative text. However, the scale of the Gemini integration—both in terms of model size and financial commitment—suggests a deeper dependency on Google’s technology.
Analysts speculate that Apple may be paying Google up to $1 billion annually for access to the custom Gemini model, though exact figures have not been disclosed. The partnership could also pave the way for broader AI interoperability, as Apple has expressed interest in adopting open standards like Anthropic’s Model Context Protocol (MCP), which would allow Siri to seamlessly integrate with other third-party AI models in the future.
Looking ahead, this development positions Siri to compete more effectively with Google Assistant and Microsoft Copilot, both of which have aggressively adopted cutting-edge AI advancements. For users, the changes could mean faster, more accurate responses—especially for complex or open-ended requests—but it also raises questions about data handling and privacy, given that some processing will occur off-device.
Apple has not yet confirmed a release date for these Siri enhancements, but they are expected to arrive with the Spring 2026 iOS update. Whether this marks the beginning of a more collaborative AI ecosystem or a temporary stopgap remains to be seen.
