This model was converted to MLX format from ResembleAI/chatterbox-turbo using mlx-audio-plus version 0.1.6.

This model uses 4-bit quantization for the T3 GPT2 backbone, reducing memory usage while maintaining audio quality.

Note: This model requires the S3Tokenizer weights from mlx-community/S3TokenizerV2, which will be downloaded automatically.
