This is a 4-bit MLX quantization of kyutai/hibiki-1b-mlx-bf16 at revision b3d6291f3dcf7954e1a502e4d66f32e3556f17ae.

The language-model weights were quantized with MLX nn.quantize(bits=4, group_size=32), leaving tiny conditioner tensors dense when their last dimension is not divisible by 32. Mimi, tokenizer, and model config files are copied from the source repository. The staged config.json changes moshi_name to hibiki-mlx-dc2cf5a5@80.q4.safetensors so compatible loaders can apply q4 group-size-32 loading before strict weight load.
