Apple CEO Tim Cook confirmed during the earnings call that the company is working on generative AI features for the upcoming iOS 18 update. The focus will be on incorporating AI in Siri for tasks like summarisation and smart reply suggestions in Messages. Apple is also exploring the use of AI in multiple apps such as Apple Music, Pages, and Keynote. The company is testing different AI models, some of which will run on-device while others will rely on the internet. More details about these AI features are expected to be revealed later this year.
