Whisper large-v3 Turbo

OpenAI's distilled Whisper variant. ~8× faster than large-v3 with most of the accuracy retained — the practical default for high-throughput STT pipelines.

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 6 GB (8 GB recommended) of video memory.
No graphics card
Works. Runs on a normal computer's processor, just slower.

The best size-for-speed Whisper for a Mac, via whisper.cpp or MLX Whisper; usable on a plain CPU, just slower than real time on old machines.

Numbers are for: official fp16 weights (809M). Based on the maker’s own figures; where the maker gives only a graphics-card figure, the Mac memory is our estimate.

Strengths

  • Roughly 8× faster than large-v3
  • Retains most of large-v3's multilingual accuracy
  • MIT-licensed weights

Weaknesses

  • Slight quality regression on the hardest non-English audio
  • No speaker diarization
