Confucius4-R2T2, MLX 4-bit
netease-youdao/Confucius4-R2T2
converted to MLX and quantised to 4 bits (group size 64, affine), for Apple
Silicon. 4.09 GB of bfloat16 becomes 1.5 GB.
Converted with mlx-audio 0.3.1:
python -m mlx_audio.convert --hf-path netease-youdao/Confucius4-R2T2 \
--mlx-path Confucius4-R2T2-mlx-4bit \
-q --q-group-size 64 --q-bits 4 --model-domain stt
The architecture is unchanged — Qwen3ASRForConditionalGeneration, the same one
Qwen/Qwen3-ASR-1.7B uses — so it loads through existing Qwen3-ASR paths in
both mlx-audio and mlx-audio-swift with no custom code.
Use
from mlx_audio.stt.utils import load_model, load_audio
model = load_model("selcukkubur/Confucius4-R2T2-mlx-4bit")
print(model.generate(load_audio("audio.wav")).text)
