Apple has rebuilt Siri to run on a mix of on-device processing and third-party large models, making the assistant the organizing centre of six new OS releases. At WWDC 2026 the company named iOS 27, iPadOS 27, macOS 27, watchOS 27, tvOS 27 and visionOS 27 and framed Apple Intelligence and a revamped Siri as the year’s main changes. Reporters covering the keynote said the assistant is now the focal point of Apple’s software strategy after multiple delays since the feature was first announced in 2024, and Apple has not yet published consumer release dates or pricing; availability windows and rollout schedules are expected in developer notes and official announcements during WWDC week.

Users will encounter deeper conversational and task completion abilities across Apple devices because Apple framed its keynote around what it calls Apple Intelligence and tied that effort to the new OS releases.

Siri rebuilt, powered by large models

Apple described a redesigned Siri that blends on device processing with cloud assisted models to deliver more capable interactions and automated tasks. Tom's Guide reported that Apple’s new Siri will run on models the outlet linked to Google Gemini, indicating Apple has moved toward building features on externally developed large language models rather than relying only on Apple built models. Mashable’s live coverage added that Apple Intelligence is being positioned to work with multiple third party models, and specifically mentioned options such as ChatGPT and Claude as potential engines behind different features. That mix signals a change in Apple’s approach to pairing privacy messaging with access to external AI models.

The practical outcomes Apple flagged include deeper conversational replies from Siri, richer follow up questions and expanded abilities to complete multi step tasks. Reporters covering the event said the assistant is the central strand tying together the OS updates, and that Apple is billing these changes as the most significant rewrite of system intelligence since the company began promoting on device machine learning.

Apple announced the next major OS cycle by name: iOS 27 for iPhone, iPadOS 27, macOS 27, watchOS 27, tvOS 27 and visionOS 27 for Apple’s spatial platform. The company emphasised AI augmentations across built in apps and system integrations rather than a single flagship product. Expected user facing features reported in pre keynote coverage include AI assisted photo editing, automatically generated wallpapers, and a tool that can design shortcuts on command.

Interface level changes also surfaced in early coverage. Tom's Guide noted that iOS 27 may add a system wide Liquid Glass slider to give users more granular control over transparency and blur effects, a feature that had been planned for earlier releases but postponed for technical reasons.

Lifehacker and other live bloggers listed additional AI driven app enhancements and tighter system integrations, although detailed release notes and final feature lists remain subject to Apple’s developer documentation later in the week.

Apple’s messaging at the keynote stressed that many AI operations will run on device when possible and fall back to cloud assisted models as needed. That hybrid model aims to balance responsiveness and privacy, while also allowing Apple to tap third party models for capabilities it doesn't build itself. Reporters noted this is a clear shift from the company’s earlier emphasis on exclusively in house models.

Functionally, the changes Apple outlined were practical rather than experimental. AI assisted photo editing promises suggested automated adjustments along with manual controls. AI generated wallpapers tie personalised art generation to system settings. And the shortcut design tool offers the kind of end user automation Apple has been expanding for years, now with generative prompts replacing manual setup. Those features are the kind reporters and early hands on live blogs singled out as immediate benefits for everyday users.

Apple opened WWDC 2026 and began the keynote at 10 a.m. Pacific on June 8, with the conference scheduled to run through Friday, June 12 at Apple Park. The keynote was streamed on Apple’s event channels, including the Apple website, the Apple TV app and YouTube. Pre keynote reporting and the live updates didn't include final consumer release dates or pricing for the OS updates, and Apple said availability windows, rollout schedules and region by region timing will be supplied in official developer notes and release announcements during WWDC week.

For developers the update path will be important. Apple’s developer documentation will probably clarify which features run purely on device, which require cloud model access and how third party model options will be exposed in APIs. That guidance will determine how fast app makers can integrate the new assistant features and whether smaller teams can ship meaningful AI driven updates this year without rebuilding backend infrastructure.

Reporters covering the event emphasised that this is a rebound moment for Siri. The assistant was first promised as a major generative capability in 2024 but experienced multiple delays. With Apple now tying a broad set of system level features to a rebuilt assistant, the company is betting Siri will be the visible measure of Apple Intelligence across its hardware ecosystem.
