Validate activity before betting a new project on vad. - Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic. ## Common questions ### What is the difference between whisper.cpp and vad? whisper.cpp: Port of OpenAI's Whisper model in C/C++ for speech-to-text inference. vad: Voice activity detector (VAD) for the browser with a simple API.
