About Ace Step 1.5
ACE-Step 1.5 is an open-source local music generation foundation model designed to run on consumer hardware. It supports Mac, AMD, Intel, and CUDA devices, and can generate full songs in under 2 seconds on an A100 GPU, or under 10 seconds on an RTX 3090. The base model requires less than 4GB of VRAM to run, and supports lightweight LoRA personalization trained on as few as a handful of songs to capture custom styles. An XL variant with a 4B-parameter DiT decoder is also available for higher audio quality, requiring a minimum of 12GB VRAM with offload (20GB recommended) for operation.
