Whisper Large V3
OpenAI's open-source speech recognition model — still the gold standard for self-hosted ASR
Verdict
Best open-source ASR model by far. 99 languages, timestamps, speaker diarization via community extensions. Self-host for free — OpenAI's own GPT-4o Transcribe now leads on raw accuracy for API users, but nothing open-weight beats Whisper for offline or on-prem transcription.
