tl;dr: Apple is overhauling Apple Intelligence with a new architecture built on foundation models co-developed with Google using Gemini technology, running both on-device and via Private Cloud Compute. The upgrade adds multimodal capabilities like image generation, advanced photo editing, and visual question answering, with higher-end devices getting expanded features such as speech generation and improved dictation. A new system orchestrator coordinates these features contextually across apps, while Apple emphasized its privacy stance as a contrast to competitors.
