Whisper
109 mentions across 7 sources · 38% positive — critical (weighted across 7 sources)
Hacker News, YouTube, Product Hunt, App Store, Stack Overflow, GitHub, Lemmy
What users praise
- • Completely free to self-host with open weights and inference code on GitHub
- • Strong accuracy on accents, background noise, and technical vocabulary out of the box
- • whisper.cpp runs practical CPU inference even on old hardware without a GPU
- • WhisperX adds word-level timestamps and speaker diarization for meetings and subtitles
What frustrates them
- • Smaller models hallucinate and loop badly on non-English audio
- • Performance degrades rather than scales when concurrency is increased
- • Integration is fiddly — errors in multipart forms, audio loading, ndarray conversion
- • Requires ffmpeg and careful preprocessing, so it isn't drop-in
