Apple is preparing to transform Siri into a full-fledged artificial intelligence chatbot, a move aimed at catching up in a generative AI race dominated by OpenAI and Google.

The overhaul, expected later this year, will embed the chatbot code-named Campos deeply into iPhone, iPad, and Mac systems, replacing the familiar Siri interface, Bloomberg reports.

Users will summon it as they do today; by voice or by holding the side button.

The new Siri promises far more than today’s assistant, which struggles with conversational flow.

Campos will search the web, generate content, create images, and even analyze uploaded files.

It will integrate across Apple’s core apps, giving the iPhone maker a footing in a market where it has lagged behind peers.

Apple’s previous AI efforts, under the Apple Intelligence platform, stumbled in 2024, delivering features that were slow and underwhelming. This revamp is central to the company’s push to turn the tide.

While the chatbot will draw on user interactions to provide personalised responses, Apple is weighing limits to protect privacy.

Under the hood, the interface will be Apple-designed, but the AI itself leans on technology from Google’s Gemini team. An interim update, iOS 26.4, will rely on Google’s Apple Foundation Models version 10, operating at 1.2 trillion parameters. Campos, however, will run a more advanced variant, Apple Foundation Models version 11, comparable to Google’s Gemini 3.

Apple is also considering a shift in infrastructure: hosting Campos on Google’s servers using high-powered tensor processing units, rather than Apple’s own cloud. The arrangement comes at a cost: roughly $1 billion annually for access to Google’s models. Apple may also draw on Google’s technology to boost other AI features.

Critics say Apple is betting that a smarter, deeper Siri could finally give it a competitive foothold in AI transforming the voice assistant from a convenience into a core battleground in Silicon Valley’s generative AI war.
