Siri AI at WWDC 2026 · Source Reflecting on WWDC 2026, Simon adopts an “I’ll believe it when I see it” stance regarding Apple Intelligence, given the overpromises of the 2024 rollout. However, he points out that the latest Siri AI features appear technically viable, powered by a custom Gemini-derived model on Private Cloud Compute and vision LLMs that extract on-screen data without requiring third-party app updates. He is particularly interested in the new Core AI library and its coreai-torch Python package, which provides a straightforward bridge for developers to export PyTorch models into native programs optimized for Apple hardware.
