Core AI is the successor to Core ML, enabling PyTorch model conversion and deployment of up to 70B-parameter LLMs on-device via unified hardware access (CPU/GPU/Neural Engine) with quantization and palettization built-in.

Summary
Eliminates per-token cloud costs, removes server dependencies, and keeps user data local—streamlining inference pipelines for developers targeting Apple Silicon. Model specialization on first load trades one-time latency for cached subsequent runs, changing how you architect cold-start handling.

Implementation verdict
Replaces Core ML for neural networks and transformers. Requires PyTorch models converted via torch.export.ExportedProgram → TorchConverter().to_coreai(). Ready now with OS release, but ecosystem maturity depends on community adoption—start with vision/reasoning models if targeting iPhone/iPad/Mac only.
