MLX port of GigaAM-v3 RNNT variant for Apple Silicon. Higher quality than CTC, ~77x realtime on M2 Max.

Usage

pip install git+https://github.com/aystream/gigaam-mlx.git

from gigaam_mlx import load_model, transcribe

model, tokenizer = load_model("rnnt")  # downloads automatically
text = transcribe(model, tokenizer, "recording.wav")

Or via CLI:

gigaam-mlx recording.wav --model-type rnnt
