Core ML Whisper Large V3 Turbo (FP16)

Core ML export of openai/whisper-large-v3-turbo tuned for Apple Silicon. The bundle reflects the Option A1 configuration and reaches ~0.024 real-time factor (RTF) when DecoderWithCache.mlpackage is used.

Usage

Load Encoder.mlpackage and DecoderWithCache.mlpackage with Core ML (MLModel(contentsOf:), MLModelConfiguration(computeUnits: .cpuAndNeuralEngine)).
Feed the tokenizer assets into Hugging Face AutoProcessor/tokenizers to maintain parity with the PyTorch reference.
Optionally fall back to:
- DecoderFull.mlpackage for non-cached decoding.
- DecoderStateful.mlpackage for experimentation (ANE planner still returns error -14 on macOS 15 betas).
