What it is

Whisper is OpenAI's flagship speech-to-text model, trained on 680,000 hours of multilingual audio. The original Python package is the reference implementation — easy to install, but intentionally simple. For production speed you almost always want a derivative (whisper.cpp, faster-whisper, whisperX) that wraps the same weights in a faster runtime. Free, MIT-licensed, runs on CPU or GPU.

Best for: Research, baseline accuracy, teams that want the canonical reference implementation.
Watch out for: Pure-Python inference is slow on CPU; no built-in speaker diarization; batch-only, no streaming.
