Apple has redesigned Siri with on-device reasoning that parses multi-step requests and understands conversational context. The new Siri handles nuanced language—casual phrasing, conditional logic, and contradictions—all processed locally on your device.
Example: 'Remind me to book my dentist when I leave the gym, unless I already have an appointment.' Old Siri would struggle. New Siri chains the logic, checks your calendar, and synthesizes an action.
The shift reflects Apple's bet that local AI reasoning is now capable enough for daily tasks. On-device models trade some raw capability for speed and privacy—a tradeoff that works for voice assistant duties.
