The new Siri with Apple Intelligence in iOS 18.1 is more conversational, lets you interrupt and offers more contextual intelligence. But how much smarter is it? I put the new Siri on the iPhone 15 Pro Max to the test versus the old Siri on the iPhone 11 Pro Max in a series of questions, from recommending local restaurants and asking about Paris to sports and weather questions. Siri with Apple Intelligence is better, but there's still room for improvement.
