Apple will gradually roll out the new AI-based features for Siri (based on Google’s Gemini AI). According to Bloomberg’s Mark Gurman, the Cupertino giant is preparing to unveil the revamped Siri “in the second half of February.”
Gurman isn’t sure whether Apple will conduct the demonstration in the form of an in-person event or a controlled briefing. However, since this is a big reveal for Apple, the company could host a small event.
A gradual Siri update begins with iOS 26.4
According to the Siri demonstration, which included features such as contextual responses (based on users’ personal information) and access to on-screen content, Apple was expected to release it with iOS 26.4.
For those still keeping up, iOS 26.4 is rumored to enter beta testing in February, with a public launch expected in either March or April (at the latest). As mentioned in the report, the version of Siri shipped with iOS 26.4 is based on “Apple Foundation Models Version 10.”
The company’s base models would be based on a customized version of Gemini that “runs on approximately 1.2 trillion parameters.” Initially, Apple will host the new AI-based features on its private cloud compute servers.
However, the introduction of some new AI-based features with Siri is just the first phase. At the Worldwide Developer Conference (WWDC) 2026, Apple plans to unveil “a completely reimagined Siri,” codenamed “Campos,” with a new interface and architecture “for the chatbot era.”
The completely redesigned Siri is reserved for iOS 27
This version of Siri, based on Apple Foundation Models Version 11, will be much more conversational, enabling live conversations (similar to Gemini Live) and providing a more chatbot-like experience than ever before. According to Gurman, this model will be far more powerful than the one we’ll see with iOS 26.4.
Instead of running this version on Apple’s private computer servers, the companies are discussing processing it “directly” on Google’s servers (using the powerful Tensor processing units).
So don’t expect to see all the AI smarts Apple has promised for Siri next month, as the company will reserve a large chunk of it for the big iOS 27 reveal. As every year, the new operating system will be officially presented with the market launch of the iPhone 18 Pro, which is expected in September 2026.
