Hi HN! We released ACE-Step 1.5, an open-sourced AI music model.
Key traits of ACE-Step 1.5:
Quality: beats Suno on common eval scores
Speed: full song under 2s on A100
Local: ~4GB VRAM, under 10s on RTX 3090
LoRA: train your own style with a few songs
License: MIT, free for commercial use
Data: fully authorized plus synthetic
Weights/Training code/LoRA code/Paper are all open.
Closed-source commercial models dominate AI music today, tying creators to a single app and model. If access disappears, or the model changes, your creative power can vanish overnight.
ACE-Step 1.5 breaks that lock-in with a competitive open-source alternative: run locally, own it, fine-tune with your songs, and reduce privacy/data-leak risk.
