Generation with this package has not been end-to-end verified yet — the weights
were converted with mlx_indextts/convert.py and pass structural checks, but only
IndexTTS-2 has a verified synthesis path at the moment. Status updates are tracked in
the inference repo. For the fully verified package, see
IndexTTS-2-MLX.
