After a decade of being the punchline in every assistant comparison, Siri just got euthanized and resurrected. At WWDC 2026 today — Tim Cook’s final keynote as CEO — Apple didn’t tweak Siri. They torched it and rebuilt the whole thing from scratch under a new name: Siri AI.

The twist? The engine under the hood belongs to Google.

The Mea Culpa Rebrand

Apple VP Mike Rockwell opened with what amounted to a corporate apology: “There are times when you expect more from Siri.” Understatement of the decade.

The new Siri AI holds multi-turn conversations, pulls from real-time web data, and — this is the big one — taps into your personal data across Messages, Mail, Photos, and other apps for genuinely contextual responses. The demos showed chains of requests that would’ve made old Siri crash and burn: identifying a photo landmark, pulling navigation, finding related family photos, and adding one to a shared album, all in a single conversation thread.

Another demo had Siri digging through Messages history to find a dessert recommendation, compiling a watch-party menu, and drafting a group text with send and edit options. If the demos reflect reality (always a big “if”), this is a fundamentally different product.

Google Powers Everything Now

Here’s the strategic earthquake. Apple’s most powerful AI tier — AFM Cloud Pro (Apple Foundation Model Cloud Pro) — runs on Nvidia GPUs inside Google Cloud. The Gemini-powered system routes heavy queries through Nvidia B200 GPUs, with Apple reportedly paying around $1 billion per year for the partnership.

This is Apple admitting buying beats building. After years and billions spent trying to develop competitive LLMs in-house, Cupertino waved the white flag on foundation models. Lighter tasks still run on-device via Apple silicon, with complex reasoning routed to the cloud through Private Cloud Compute.

The irony is thick: Apple is now deeply dependent on its biggest search rival for the AI backbone of its most important software feature. Google essentially becomes the Intel Inside of AI assistants — powering both its own Gemini and Apple’s Siri AI, while collecting cloud revenue from Apple.

OpenAI is the clear loser here. ChatGPT was integrated into iOS 26, but this Gemini partnership signals that relationship is dead or dying. Reports suggest OpenAI was already considering legal action over the “strained” partnership. This makes things significantly worse for Sam Altman’s crew.

The Dedicated App Nobody Expected

Siri AI gets its own standalone app for the first time — and this is more significant than it sounds. Users can scroll through conversation history, revisit results, and start new threads. Conversations sync across devices via iCloud. Auto-deleting chats give privacy-conscious users control over retention.

On Mac, Siri embeds into Spotlight and right-click context menus. On visionOS, it gets a 3D visualization you can place anywhere in your space. Voice customization sliders let you tune pace and expressiveness.

This signals Apple sees Siri AI as a full conversational interface competing with ChatGPT and Claude — not just a voice command layer competing with Alexa.

The EU Gets Nothing

Significant asterisk: Siri AI won’t launch in the EU or China. Apple cited “regulatory challenges” — code for the ongoing Digital Markets Act standoff.

This is becoming Apple’s ugly pattern. EU consumers pay identical premium prices for hardware while getting materially worse software. It strengthens the regulatory argument rather than weakening it. The EU isn’t going to capitulate because Apple withholds features.

Cook’s Exit, Apple’s Crossroads

This was Tim Cook’s farewell WWDC before handing the CEO title to hardware chief John Ternus in September. He was visibly emotional: “I truly believe the best is still ahead.”

Apple’s stock actually slid during the keynote, turning negative after opening up 2%. Wall Street wanted more. In a world where every tech giant spends hundreds of billions on AI, Apple needs to prove its approach — privacy-first, partner-powered — delivers results that matter.

Agents Go Mainstream

Buried in the announcements: the Passwords app now uses Apple Intelligence to “agentically take action on your behalf,” automatically navigating to websites to fix insecure passwords. It’s a small feature with enormous implications. AI agents aren’t just for developers anymore — they’re coming to the features your parents use.

What This Actually Means

Google is winning the AI era by powering everyone else. They run their own Gemini assistant AND Apple’s Siri AI. That’s an extraordinary strategic moat.

The privacy-AI tradeoff is being tested. Apple’s betting it can deliver powerful cloud AI with genuine privacy guarantees through Private Cloud Compute. If they pull it off, it becomes the model. If they fail, it validates the “you can’t have both” crowd.

Apple admitted it can’t go alone. For a company built on vertical integration and control, leaning this hard on Google and Nvidia is a seismic cultural shift. Whether it’s pragmatic or desperate depends on how Siri AI actually performs when it ships this fall.

One thing’s certain: the AI assistant wars just got a lot more interesting — and a lot more concentrated. Google’s fingerprints are now on practically every AI product consumers touch.
