What is WhisperKit? WhisperKit is a pure Swift package built by @argmaxinc that enables real-time Whisper inference on iPhone, Mac and even Apple Watch in two lines of code. It is built on Core ML and can be configured to run on the Neural Engine or GPU or both. WhisperKit models are published and distributed through the Hugging Face Hub. Anyone can publish a Whisper fine-tune and evaluate it on their own dataset using WhisperKit!
