ACE-Step v1.5 (Developer Edition)
Hey guys, big one dropping today 🚀 This is hands-down the best open-source music generator yet.
ACE-Step v1.5 delivers full, actually-produced songs up to five minutes long. Everything runs locally, it’s fast, and it scales from high-end GPUs down to just 4GB of VRAM.
You prompt a song and it plans the structure, lyrics, and flow first, then renders the track clean and coherent. No weird drift, even on longer songs or across 50+ languages.
This finally feels like a real creative tool, not a demo.

This is the moment open-source music generation stopped feeling experimental and started feeling usable.
