We open-sourced MusePro, a Metal-based realtime AI drawing app for iOS

The standout is the real-time feedback loop: Pencil input feeds sub-second inference over WebSockets so your composition evolves as you draw, not after the fact. UX tools like influence sliders, pause, seed shuffle and one-tap enhancers (2x upscaling, background removal) give artists control instead of handing everything to the model — clever engineering that still leaves open questions about on-device vs cloud inference and latency/cost tradeoffs.
