Tim Cook launched Siri in 2011 and watched it become a punchline.
Today, in his last keynote, he's set to fix it by borrowing someone else's brain.
Coffee at the ready…
The Big Sip

Apple Gemini Siri is the biggest bet of the AI era, and Apple is making it by refusing to build a model.
At today's keynote, Cook is expected to unveil a rebuilt Siri running on a custom Google Gemini, reportedly for $1bn a year. Every rival spent billions building frontier models.
Apple is betting on the 2 billion devices they run on instead.
Watch the keynote, because the one taking the real risk might not be writing the cheque.
Here’s Your Brew

Start with the snub.
OpenAI built GPT. Anthropic built Claude. Google built Gemini. Microsoft built MAI. Every ego in tech decided owning a model was survival. The most valuable company on earth shrugged, looked at the bill, and said no thanks.
Its plan, per Bloomberg: license a 1.2-trillion-parameter Gemini model and distil a smaller version to run on-device.
The logic is colder than it looks.
Models are converging. GPT, Claude, and Gemini now trade blows on most tasks. When the product commoditises, the supplier loses pricing power. Apple is betting the model becomes a swappable part.
And the value sits in the interface 2 billion people already trust.
So Apple is building a toll booth.
iOS 27 brings an "Extensions" system letting users swap in Claude, ChatGPT, or Gemini. Apple doesn't care who wins the model war. It taxes the road every model drives down.
Google, reportedly, just bought the first lane for $1bn.
Here's the part Google won't put on a slide.
By taking the cheque, it's training 2 billion people to treat Siri as the front door and the model as plumbing they never see. Apple keeps the customer. Google keeps the bill. The day Gemini stops being the cheapest good-enough option…
Apple swaps it out and nobody notices.
The catch for Apple: it promised this exact Siri in 2024 and shipped nothing for two years.
Renting the brain fixes the capability gap, not the execution. If the autumn launch slips again:
The cleverest strategy in tech still ships late.
Two Sides, One Mug
Pro: Owning distribution beats owning the model when models become interchangeable, so Apple captures value while rivals burn cash on compute.
Con: Apple just made its most important feature dependent on a direct competitor, with no in-house fallback if the deal sours.
Our read: Apple rented the capability and held onto the customer. Google is the one exposed if the bet sours.
Receipt of the Day
[Analysis] MacRumors — "What to Expect From WWDC 2026: Gemini-Powered Siri"
Reports say Apple's next-generation Foundation Models will be built on Google Gemini, for roughly $1bn a year.
Why it matters: If it holds, this is Apple admitting the model layer isn't where it plans to compete.
Spit Take
Apple's set to rebuild Siri on a 1.2-trillion-parameter model it didn't make.

Apple rents its AI brain from Google. Smart or scary?
