After years of basic utility like setting timers and making calls, Apple's digital assistant has received a major overhaul with the launch of Siri AI. Fifteen years after its debut on the iPhone 4S, Apple has developed its own Apple Foundation Models—working both on-device and across Apple servers—to deliver concise and genuinely useful responses.
Beyond conversational upgrades, Siri AI features are embedded across iOS and macOS ecosystems. Users with eligible devices, such as an iPhone 17 Pro or higher, iPhone Air, or M3 Macs with at least 12GB of RAM, can take advantage of the more expressive Siri voice settings.

Visual Intelligence is deeply integrated into iOS and macOS, turning any on-screen content into a source for Siri AI. Users can highlight text on an iPhone and hold to access Ask Siri, or right-click on a Mac. Additionally, the Clean Up photo editing tool has been vastly improved by running through Private Cloud Compute, allowing for reliable object removal and shadow handling when switched to the High Quality setting.
Apple's shift toward running proprietary foundational models highlights its strategy to balance on-device privacy with cloud processing power. By utilizing Private Cloud Compute, complex tasks like image cleaning and email context analysis can be executed securely without compromising user data.
Another powerful addition is Siri AI's Mail integration. Once local data indexing is complete, users can triage emails using natural language prompts without opening the Mail app. Furthermore, users can toggle settings like Automatically Send Messages to streamline messaging tasks by removing redundant confirmation steps.
