ACE Music

We're releasing ACE-Step-v1.5(2B), a fast, high-quality open-source music model. It runs locally on a consumer-grade GPU, generates a full song in under 2 seconds(on an A100), supports LoRA fine-tuning, and beats SUNO on common eval metrics. GitHub: github.com/ace-step/ACE-S… Key traits: 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 The music AI space lacks commercial-grade open models. Many creators are forced to rely on closed-source services, and can’t fully own, run locally, or fine-tune their own models. We want to help change that.

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 Try it for free at acemusic.ai Weithgts and code: GitHub: github.com/ace-step/ACE-S… Hugging Face: huggingface.co/ACE-Step/Ace-S… (3 variants: xl-base, xl-sft, xl-turbo) XL demos: #XLDemos" target="_blank" rel="nofollow noopener">ace-step.github.io/ace-step-v1.5.…

Update: the ACE-Step ComfyUI node now supports a free online API as an easy fallback (great if you can’t run locally): registry.comfy.org/nodes/ACE-Step… (We also fixed a bug from the first release.) Here’s a quick tutorial 👇

Update: We just shipped two things for ACE-Step 1.5 1. A ComfyUI node that calls our online API (free, and will stay free forever): registry.comfy.org/nodes/ACE-Step… 2. A hosted API (also free forever). If you’re building a client UI around the local model, consider integrating this as a fallback for people who can’t run it locally.

ACE-Step 1.5 just shipped a stable release (v0.1.0). It includes VRAM detection with automatic model selection/optimization (friendlier for low-VRAM GPUs), a smoother one-click launch script, broader hardware support (AMD + Intel GPUs), plus bug fixes and small improvements. Release v0.1.0: github.com/ace-step/ACE-S…

See you guys 9h later :p

X is like: “you need to post more to prove there's a human behind this account”. I guess it's because I'm a new account. Fair enough. Quoting our ACE-Step 1.0 open-source post here so everyone has the backstory.

Hi X, we’re the team behind ACE-Step (and ACE Studio). This account is ACE Music. We’ll share ACE-Step updates and news about acemusic.ai, an upcoming open-source AI music platform. Follow along for releases, demos, and progress. #acestep #opensource #acestudio #acemusic
