I converted the ACE-Step 1.5 XL Base model from FP32 to BF16. The original weights were ~18.8 GB in FP32, this version is ~7.5 GB - same quality, lower VRAM usage. The Base model is the go-to starting point for fine-tuning (LoRA, etc.) - if you want to train your own style, this is the one to use. A great tool for that is Side Step. 🤗 I also converted the XL Turbo variant yesterday: Reddit post | Model submitted by /u/SpiritualLimit996 [link] [comments.
