Apple introduced Siri AI on Monday in Cupertino, a ground-up rebuild of its 15-year-old assistant whose most demanding workloads will run on Nvidia GPUs inside Google’s cloud, powered by a model Apple executives told developers was “similar in quality to Gemini Frontier models.” It’s the kind of admission that, two years ago, the company would’ve buried in a footnote.

The architecture has two tiers. Routine requests stay on the device via Apple Foundation Models. Harder ones route to AFM Cloud Pro, which Apple is benchmarking, on stage and by name, against Google’s frontier system. Craig Federighi, the senior vice president for software engineering, framed the dependency as a discipline rather than a concession. “We believe privacy in AI is non-negotiable,” he said, adding that “data is only used to execute your request, and outside experts can continue to verify this promise at any time.” He took an oblique swing at the rest of the industry, which he said “appear to be racing forward, seemingly pursuing AI for the sake of AI.”

The market wasn’t moved by the framing. Apple opened up roughly 2 percent and closed down nearly 2 percent, the kind of intraday reversal that tends to follow keynotes where the headline product is also a tacit acknowledgment that someone else built the engine.

Siri AI won’t ship in Europe or China at launch, with Apple citing local rules. A developer beta opened the same day; consumer release is slated for the fall alongside new hardware. The geographic carve-out is its own story: the two regions where Apple’s regulatory and political position is most fragile are also the ones being deferred.

This was also Tim Cook’s last WWDC as chief executive. On April 20 the company announced that John Ternus, a 25-year Apple veteran running hardware engineering, would succeed him; Cook becomes executive chairman on September 1. From the stage Cook said that “to deliver experiences that enrich people’s lives has always been our north star,” and that “I truly believe the best is still ahead.”

Under Cook, who took over from Steve Jobs in 2011, Apple’s stock has risen roughly 2,000 percent on a split-adjusted basis, per NPR’s account of the keynote. The succession lands at the precise moment the company is, for the first time in a generation, renting somebody else’s intelligence to power its own.
