Following years of development bottlenecks, Apple officially introduced Siri AI at its Worldwide Developers Conference (WWDC), built on a new architecture modeled after frontier systems like ChatGPT and Google Gemini. The smartest tiers of Siri are moving toward a paid subscription structure, splitting capabilities across two tiers: a free tier for basic functionality, standard voice commands, on-device app execution, and personal context scanning; and a premium tier for deep conversational answers, multi-turn “world knowledge” queries, complex text/image generation, and advanced reasoning tasks. To power cloud-based queries, Apple is deploying Nvidia’s leading AI chips running across Google’s cloud servers, built on a customized architecture co-developed using Google’s Gemini models. Apple is matching a pattern set by competitors, with ChatGPT offering ChatGPT Plus / Pro ($20 – $200/month) and Gemini offering Gemini Advanced. Apple is using minor rate limits within its iCloud+ subscriptions to gauge demand, with the basic Siri AI upgrade rolling out to compatible devices in a beta phase later this year, while the dedicated premium paywall is expected to materialize once advanced multi-agent features mature. This premium Siri subscription is separate from Apple’s existing third-party extension partnerships.
