The keynote is Monday at 10am Pacific, Apple Park, the usual production. The piece that matters this year is what happens in the afternoon. The developer beta drops the same day Apple announces it, and whatever gets unveiled in the morning will be judged by lunchtime by whether developers can actually install the feature they just watched in a sizzle reel. For Siri 2.0 specifically, that is the entire test.
Apple promised the rebuilt Siri at WWDC 2024. It slipped through iOS 25, slipped through iOS 26, blew up the AI org chart in February when the in-house model timeline visibly stopped pretending to converge with the marketing one. The Mark Gurman, Bloomberg, and AppleInsider triangulation across the last six weeks has been remarkably consistent: a rebuilt Siri ships in iOS 27, lives partly inside the Dynamic Island, gets a standalone app, finally remembers the previous turn of conversation, finally reads what is on screen, finally takes actions across third-party apps. Apple has to put that on stage. It also has to land it in beta 1 Monday afternoon. Anything announced for “later this fall” is the third “coming soon” in a row and will be read that way.
The other consistent leak is the part Apple would prefer not to lead with. The cloud reasoning behind the new Siri is reportedly a custom Google Gemini model, roughly 1.2 trillion parameters, that Apple is paying Google about $1 billion a year to operate. Apple’s own on-device models handle the easy local stuff, Gemini does the heavy lifting through Private Cloud Compute. For a company that pitches silicon-to-software vertical integration as the whole point, renting frontier reasoning from Google is a meaningful concession. Whether Craig Federighi says “Gemini” on stage Monday or whether it gets buried three layers down in a developer session titled something like “Extensibility for Private Cloud Compute Providers” is the second piece of theatre to watch.
There is also a layer on top of all of this that the keynote has to share oxygen with: most of the trade press is treating Monday as Tim Cook’s last WWDC keynote. That framing turns the morning into a partial legacy-management exercise, which is in genuine tension with the other thing the morning has to be. A legacy keynote is celebratory, retrospective, and broad. A “we are actually fixing Siri this time” keynote is technical, specific, and willing to concede that the last two years did not go well. Apple cannot fully do both inside two hours, and the choice of which one drives the structure will tell you how much Apple itself believes the Siri demo is going to land.
The single number to watch is how many of the announced Siri features get marked “available in the developer beta starting today.” If it is most of them, Apple Intelligence is back in the conversation. If the slide says “rolling out throughout the year,” then Gemini is the conversation, and the next twelve months of Apple AI coverage write themselves.
