During Apple's earnings call, Cook was asked about his views on future iPhone models in terms of form innovation. Normally, he would refuse to disclose information on future products, but this time he gave an encouraging answer. "I think there's a lot more to come, iPhone innovation is far from over, there's still a lot of room for innovation in smartphones, and I'm incredibly optimistic about our product line," Mr. Cook said. Some analysts point to DeepSeek, the hottest big model for Chinese companies seeking depth. Mr. Cook believes that DeepSeek's artificial intelligence model represents "innovation that drives efficiency". "Overall, I think innovation that drives efficiency is a good thing."
