APPLE'S SIRI AI CAN BE SWAPPED OUT FOR CLAUDE, CHATGPT, CODE SHOWS

Summary from the TLDR AI newsletter

Private iOS 27 and macOS frameworks show Apple built Siri so Claude or GPT-5.6 can sit in as the brain: Model Delegation lets Claude handle a natural-language ask, then hand Reminders or Messages back to Siri, and an inference-provider path can swap Apple's server-side Siri model entirely while keeping Siri's UI and voice. A demo already has ChatGPT finding emails, summarizing action items, and texting a contact through Siri's tools. The hooks are not user-facing yet, but they land as iOS 27 ships and after EU DMA pressure to open Siri to rivals.
