Open the original- What it measures
- The same table as the Apple and Parakeet facts. Whisper ran on the author's Mac, so the time reflects that machine and that model size.
- What it does not show
- A single run on one episode. Whisper runs faster on some Macs and with smaller models, so this figure does not describe every Whisper app.
