mlx-community/Fun-CosyVoice3-0.5B-2512-8bit
This model was converted to MLX format from FunAudioLLM/Fun-CosyVoice3-0.5B-2512 using mlx-audio-plus version 0.1.4.
This model uses 8-bit quantization for the Qwen2 LLM backbone, reducing memory usage while maintaining quality.
Usage
pip install -U mlx-audio-plus
