Apple Rebuilds Siri From the Ground Up, and Quietly Hands the Brains to Google

Apple used its Worldwide Developers Conference at Apple Park to reintroduce its long-criticised voice assistant as 'Siri AI', a rebuild the company describes as its most significant overhaul of the assistant to date. The rebrand acknowledges, at least implicitly, how far Siri had fallen behind the conversational AI assistants that reshaped user expectations over the past few years, and it sets up the assistant as a central pillar of Apple's software story rather than an afterthought.

The most striking detail is what sits underneath. After years of being seen as a laggard in generative AI, Apple has signed a multi-year agreement to run Siri AI on Google's Gemini models, a deal reported to cost the company around $1 billion a year. For a company that prizes vertical integration and rarely cedes core technology to outside vendors, leaning on a direct competitor's models for the brains of its flagship assistant is a remarkable concession, and a tacit admission that buying capability was faster than building it.

An unlikely partnership

The Google arrangement is striking precisely because the two companies compete head-to-head in smartphones, with the iPhone and Android pitted against each other globally. Yet the partners already have a long commercial relationship, most visibly the arrangement that makes Google the default search engine on Apple devices. Outsourcing the heavy lifting of large-language-model reasoning lets Apple close a capability gap quickly, while the reported billion-dollar annual cost underscores both how expensive frontier AI has become and how seriously Apple now treats the assistant's reinvention.

Privacy framing intact

Apple insisted the partnership does not abandon its privacy posture. Requests can be handled on-device, routed through its Private Cloud Compute servers, or sent to Gemini only when the heavier reasoning is required. The redesigned assistant can read on-screen content, understand personal context and chain actions across apps with far less prompting. This tiered approach, keeping lightweight tasks local and escalating only the most demanding queries off-device, is designed to reassure users that personal data is not being indiscriminately shipped to a third party.

• On-device processing for lighter, privacy-sensitive tasks
• Apple's Private Cloud Compute servers for intermediate requests
• Google's Gemini models reserved for the heaviest reasoning
• New abilities: reading on-screen content, understanding personal context, chaining actions across apps

The capacity to read what is on screen and string together multi-step actions across apps points toward a more agentic assistant, one that can carry out tasks on a user's behalf rather than simply answering questions. That shift, if it works smoothly, would represent the most consequential change to how people interact with their iPhones in years.

A broad software wave

The reveal landed alongside iOS 27, iPadOS 27 and macOS 27 Golden Gate, with matching updates across watchOS, visionOS and tvOS. All are due as free updates this autumn, putting a Google-powered Siri in the hands of hundreds of millions of iPhone owners. By bundling the assistant's relaunch into its annual platform refresh, Apple ensures Siri AI reaches an enormous installed base almost immediately, rather than as a niche feature gated behind new hardware.

The reinvention carries real stakes. If Siri AI delivers the responsiveness and contextual intelligence users now expect, Apple can neutralise one of its most persistent criticisms and reframe the iPhone as a credible AI device. If it stumbles, the company will have spent heavily and ceded ground to a rival only to fall short again. The autumn rollout will reveal whether outsourcing the brains was a pragmatic masterstroke or a dependency Apple comes to regret.

The NE Times View

Apple outsourcing Siri's intelligence to Google is the most consequential admission in the company's recent history. The NE Times View: the firm that built its brand on doing everything in-house now rents its AI brain for a reported billion a year, conceding it fell behind. For users this may finally make Siri useful; strategically it deepens Apple's dependence on a rival. Convenience today, vulnerability tomorrow, is a risky trade for a control-obsessed company.
