ACE-Step-1.5-xl is out now.
We scaled the DiT decoder to 4B. And it shows better audio quality, better prompt following, and better musicality. It still fast -- 8 steps with turbo distillation.
What didn't change:
- Same generation API, same LoRA training code, same everything
- All LM models (0.6B / 1.7B / 4B) fully compatible with all 3 variants
- Your existing projects work with XL — no changes needed
