Whisper.cpp is loved because it is a lightweight C/C++ port of OpenAI’s Whisper model. However, without a dedicated feature to leverage your Windows PC's graphics card, transcribing long audio files on a CPU can take a very long time. Having built-in GPU acceleration allows the app to perform heavy AI math lightning-fast without freezing your computer. SourceForge Note: No CUDA support in pure Whisper
