Apple is facing challenges with its intelligence features and is working on rebuilding Siri from the ground up, internally known as 'LLM Siri'.
Key issues include the reluctance to invest in AI, starting late, and the struggle to integrate generative AI with the old Siri.
Apple is overhauling Siri to be more conversational and better at synthesizing information by developing a new architecture based on the LLM engine.
The company plans to leverage iPhones and differential privacy for better data synthesis and is considering letting the LLM version search the web for data.
