This is a BF16, single-file conversion of ACE-Step/acestep-v15-xl-sft for use with ComfyUI and other single-safetensors loaders.

Place acestep-v15-xl-sft-bf16.safetensors in your ComfyUI model directory (exact path depends on the custom node you are using for ACE-Step). No shard index is needed.

Converted with safetensors + torch on Kaggle (GPU runtime). All floating-point weights cast to bfloat16; integer/bool buffers unchanged.
