Tomorrow could be Apple’s most important AI moment yet. WWDC 2026 is expected to be all about one thing: making Siri relevant again. If the leaks are right, Apple is rebuilding Siri around a custom Google Gemini model, reportedly around 1.2 trillion parameters. For context: Apple’s own on-device AI model is roughly 3B parameters. The biggest rumor: Apple’s new Siri will reportedly be powered in the background by Google Gemini. Not as a Google-branded chatbot, but as an Apple-controlled intelligence layer running behind Siri, likely tied to Apple’s privacy-first infrastructure. So the new Siri likely becomes a hybrid system: • small Apple model locally on your device • large Gemini-class model in the cloud • Siri as the orchestration layer • Apple controlling the UI, app access and privacy layer What to further expect: • a much more conversational Siri • deeper personal context across apps, messages, files, calendar, photos and contacts • screen awareness • actions inside apps • a dedicated Siri app with chat history • voice chat, file uploads and multimodal interaction • better integration with Dynamic Island • optional support for other AI services like ChatGPT, Claude or Gemini Apple wants to turn Siri into the private AI layer of the operating system. A system agent that can search, understand, write, edit, summarize, organize and act across your iPhone, Mac and iPad. We may also see new Apple Intelligence features for: • AI photo editing • smarter Camera / Visual Intelligence • improved Writing Tools • natural-language Shortcuts • better Wallet and Health integrations • more privacy controls around AI data Either way, WWDC 2026 could define Apple’s position in the AI race. Exciting how the new CEO will handle all of this. Images: Bloomberg, Mark Gurman
