parakeet-mlx. Neat MLX project by Senstella bringing NVIDIA's Parakeet ASR (Automatic Speech Recognition, like Whisper) model to to Apple's MLX framework.

It's packaged as a Python CLI tool, so you can run it like this:

uvx parakeet-mlx default_tc.mp3

The first time I ran this it downloaded a 2.5GB model file.

Once that was fetched it took 53 seconds to transcribe a 65MB 1hr 1m 28s podcast episode (this one) and produced this default_tc.srt file with a timestamped transcript of the audio I fed into it. The quality appears to be very high.
