Apple Unveils Siri AI at WWDC 2026: A Complete Overhaul Powered by Apple Intelligence

Apple kicked off WWDC 2026 at Apple Park on June 8 with a headline announcement that has been years in the making: an entirely rebuilt Siri, now called “Siri AI,” powered by the latest Apple Intelligence stack. The company’s press release described it as “a profoundly more capable and personal assistant” — and based on what was shown, that is not just marketing language.

What Changed

The new Siri AI moves away from the single-turn, command-response model of the past. It now supports:

• Multi-turn natural conversation: Back-and-forth dialogue that remembers context across exchanges, rather than resetting after each interaction
• Detailed, engaging responses: Instead of one-line answers, Siri AI can explain, elaborate, and adapt its tone based on the conversation
• Deeper system integration: Siri AI can perform more complex workflows across apps, pulling data from Messages, Mail, Calendar, and third-party apps with user permission
• On-device processing improvements: More of Siri’s intelligence now runs locally on-device, reducing latency and improving privacy

Apple Intelligence Rebuilt

The underlying Apple Intelligence stack received a major update. Apple is pulling out all the stops to regain its position in the AI assistant race, where competitors like Google and OpenAI have had a multi-year lead. The new stack combines:

1. A larger on-device language model optimized for conversational tasks
2. Private Cloud Compute for requests that exceed on-device capacity
3. Tighter integration with iOS 27, which itself received significant AI-powered updates to Photos, Maps, and Messages

The Gemini connection

In January 2026, Apple and Google announced a multi-year collaboration under which the next generation of Apple Foundation Models is based on Google’s Gemini models and cloud technology (joint statement; Reuters). The statement says Apple Intelligence continues to run on Apple devices and Apple’s Private Cloud Compute, under Apple’s privacy standards. In other words, Gemini technology underpins Apple’s models, but requests are processed on Apple’s own infrastructure rather than being handed to the Gemini app.

What developers get

Apple’s developer announcement adds several pieces:

• App Intents updates let apps connect to Siri AI capabilities such as personal context, app actions and on-screen awareness.
• The Foundation Models framework becomes a single Swift API for on-device models (now with image input), server models and custom skills. Developers in the App Store Small Business Program with fewer than 2 million total first-time downloads can use the next-generation Apple Foundation Models on Private Cloud Compute at no cloud API cost. Models from other providers, such as Claude or Gemini, can be plugged in through a new language model protocol.
• Core AI is a new framework for running custom models on device, optimised for Apple silicon.
• Xcode 27 brings coding agents from Anthropic, Google and OpenAI into the IDE, with planning, previews and the ability for agents to run tests and validate their own work.

Other Apple Intelligence features announced

Apple’s announcement lists several features beyond Siri: Spatial Reframing in Photos to improve a photo’s composition after it is taken; Notify Me in Safari, which monitors a web page for changes such as restocks or price drops; one-tap suggestions in Messages to create a reminder or note from a conversation; and photorealistic images in Image Playground. It also announced new parental controls, including child accounts, Ask to Browse in Safari and Screen Time allowances by app category.

Availability and requirements

According to Apple’s WWDC26 announcement:

• Timing. Developer testing began on the day of the keynote, a public beta was scheduled for the following month through the Apple Beta Software Program, and the features arrive as a free update in the fall with iOS 27, iPadOS 27, macOS 27, watchOS 27 and visionOS 27.
• Siri AI is labelled beta. It will be available as a beta later in the year for supported devices set to English, with more languages to follow.
• Supported devices. iPhone 15 Pro and Pro Max, iPhone 16 models or later, iPad mini (A17 Pro), iPads and Macs with M1 or later, MacBook Neo (A18 Pro), Apple Vision Pro, and Apple Watch Series 9 or later, Ultra 2 or later and SE 3 when paired with an Apple Intelligence-enabled iPhone.
• Regional limits. Siri AI is not initially available in the EU on iOS, iPadOS and watchOS (Mac and Vision Pro users in the EU can use it in a supported language). Siri AI and the other new Apple Intelligence features are not available in China while Apple works through regulatory requirements.
• Usage limits. Some features that rely on server models, including image generation, have daily usage limits; most iCloud+ plans raise them.

What to watch

Apple has had a difficult history with Siri upgrades: features previewed at WWDC 2024 were delayed. The beta label, English-first rollout and regional exclusions mean the experience in fall 2026 will differ by country and language. The useful signals to watch are how reliably cross-app actions work in the public beta, how quickly other languages arrive, and how many third-party apps adopt the updated App Intents.
