Apple Reframes Siri with AFM 3 at WWDC 2026

Apple published a technical overview of its third-generation foundation-model family (AFM 3) at WWDC 2026, announcing five models across on-device and cloud tiers, per Apple Machine Learning Research. The family includes two on-device models: AFM 3 Core (3-billion-parameter dense) and AFM 3 Core Advanced (20-billion-parameter sparse, activating just 1-4B parameters via Instruction-Following Pruning). Three server-based models run on Private Cloud Compute: AFM 3 Cloud, ADM 3 Cloud for image generation, and AFM 3 Cloud Pro, which runs on NVIDIA GPUs within Google Cloud while retaining Private Cloud Compute privacy guarantees (Apple ML Research). In side-by-side human evaluations, Apple reports AFM 3 Cloud was preferred on 64.7% of prompts versus 8.7% for the 2025 server baseline. Bank of America characterised the announcements as a 'material positive reset' for Apple's AI ambitions, per Seeking Alpha.
