acestep-v15-xl-sft

ACE-Step v1.5 is a powerful open-source music foundation model that turns a text prompt into a complete song — vocals, lyrics, and instrumentation — at quality that rivals commercial tools. We run the high-quality XL checkpoint with its planning step ("thinking") on by default, so generations favor musical structure and coherence over raw speed.
