Neural Engine Optimized Stable Diffusion Inference

via “neural engine-optimized stable diffusion inference”

Run Stable Diffusion on Mac natively

Unique: Uses split_einsum Core ML model variant specifically optimized for Apple Neural Engine, enabling 3-5x faster inference than standard CPU/GPU-only implementations by distributing diffusion steps across specialized hardware; achieves this through custom model compilation pipeline that preserves numerical stability while exploiting ANE's 16-bit compute capabilities.

vs others: Faster and more power-efficient than cloud-based APIs (Replicate, Stability AI) for local generation, and significantly more memory-efficient than PyTorch implementations on Mac (150MB vs 4-8GB), but requires pre-converted Core ML models rather than supporting arbitrary checkpoints.
