Stable Audio 3 Small-Music — MLX weights

Stable Audio 3 Small-Music — MLX weights for WhisperKit

These files are format conversions of weights published by Stability AI at
https://huggingface.co/stabilityai/stable-audio-3-optimized. Nothing was
retrained or altered: the MLX .npz archives were rewritten as safetensors,
which is the only container MLX Swift can read, and the tokenizer and three
conditioner tensors were extracted from those same archives.

File	Contents
t5gemma_f16.safetensors	T5Gemma text encoder
dit_sm-music_f16.safetensors	Diffusion transformer, small-music
same_s_decoder_f32.safetensors	SAME-S audio decoder
sa3_conditioner_sm-music.safetensors	Conditioner tensors from the DiT archive
t5gemma_tokenizer.model	SentencePiece tokenizer from the T5Gemma archive
