What it is

An opinionated CLI wrapper around Hugging Face Transformers + Flash Attention + BetterTransformer. Trades install complexity for throughput: ~150 min of audio in ~98s on an A100. The reference for "how fast can Whisper go on current hardware." Apache-2.0.

Best for: Batch-processing huge backlogs on rented H100/A100 time.
Watch out for: Requires an NVIDIA GPU with enough VRAM for Whisper-large-v3 + Flash Attention; CPU path is not practical.
