What you need to run it

Mac
Yes. Any Apple Silicon Mac (M1 or newer) with at least 8 GB (16 GB recommended) of memory. Newer chips are faster, but memory is what decides whether it runs.
Windows / Linux PC
NVIDIA works best. A graphics card with at least 10 GB (12 GB recommended) of video memory.
No graphics card
Not practical. Too slow without a graphics card or Apple Silicon.

Runs well on Apple Silicon through whisper.cpp or MLX Whisper, but is slow on a CPU alone.

Numbers are for: official fp16 weights (1.55B); quantized whisper.cpp builds are smaller. Based on the maker’s own figures; where the maker gives only a graphics-card figure, the Mac memory is our estimate.

Strengths

  • Multilingual (99 languages)
  • Robust to noise and accents
  • Open weights — runs offline

Weaknesses

  • Slow on CPU; needs a GPU for real-time
  • No speaker diarization built in
  • Hallucinates on long silence
