Gurman Details Schedule for Siri’s Transformation

Apple Siri remains the laughing stock of digital assistants, but with the move to a Gemini backend, that’s about to change. This past weekend, Bloomberg’s Mark Gurman provided more details about this shift and its schedule, building on some earlier reporting.

According to Gurman’s latest missive, and it’s a long one, Apple will finally unveil its new Gemini-powered Siri update next month, in February, in an iOS 26.4 developer beta that will then make its way to a public beta before being released to all iPhone users. But Gurman says Apple may even hold an event to trumpet the belated release so it can show off all the features it announced for Siri back in June 2024.

Gurman writes that Apple used Gemini to create what it calls Apple Foundation Models version 10. It has nearly 1.2 trillion parameters and is hosted on its Apple Private Cloud Compute infrastructure.

A “full Siri overhaul” is codenamed “Campos” and is still expected in iOS 27 (and other Apple platform releases). This is the so-called conversational Siri, and it will be unveiled at WWDC 2026 this June before a public release in September, as expected. Unlike the current Siri, this version of the assistant is being rebuilt from scratch with a new user interface and underlying architecture, and it will resemble chatbots like OpenAI ChatGPT and Anthropic Claude.

Conversational Siri will run on the Gemini-based Apple Foundation Models version 11. It will be “competitive” with Gemini 3, Gurman says, and capable of the back-and-forth conversations that are now common everywhere else. Interestingly, Apple is examining whether it should run these models on Google’s more powerful AI infrastructure instead of its own.

Apple is also working on an overhaul of its Safari web browser that’s “built for the AI era” and will try to counter Perplexity Comet, OpenAI ChatGPT Atlas, and other new-generation AI web browsers. Gurman says that this project is currently paused, likely because of the shift to Gemini and the importance of figuring out Siri first. But it could still show up at WWDC.

Apple is reportedly also overhauling Calendar and looking at adding chatbot-type UIs to apps like Safari, TV, Health, Music and Podcasts. But with Siri finally on track, it’s likely that we’ll simply see Siri integration across the board now. And then there’s the so-called HomePod that has been delayed repeatedly because of the problems with Siri. Gurman says Apple is now testing three versions of this smart display and various associated smart home devices. But it’s not clear when the first of them will debut.
