How to use ACE-Step/Ace-Step1.5 with Transformers:
# Use a pipeline as a high-level helper from transformers import pipeline pipe = pipeline("text-to-audio", model="ACE-Step/Ace-Step1.5", trust_remote_code=True)# Load model directly from transformers import AutoModel model = AutoModel.from_pretrained("ACE-Step/Ace-Step1.5", trust_remote_code=True, device_map="auto") - Notebooks
- Google Colab
- Kaggle
Please add a LICENSE file to the weights repo (and clarify the Qwen2.5-Omni variant)
Hi β thanks for releasing ACE-Step 1.5. I'm porting it to Apple MLX and hit two small documentation gaps that are easy for you to close and would help every downstream porter.
1. LICENSE file for the weights. The GitHub repo has a clear MIT LICENSE (Copyright (c) 2026 ACEStep), but this weights repo has no licence file β MIT here is the HF tag and the model card only. MIT's text grants rights in "the Software and associated documentation files," which doesn't obviously reach checkpoints in a separate repo. Could you either commit the MIT LICENSE here, or add a README line stating the MIT grant covers the model weights? (ALT_VAE.md currently lists the bundled VAE as "(project license)", which adds to the ambiguity.)
2. Which Qwen2.5-Omni variant trained ACE-Captioner/ACE-Transcriber? The tech report Β§2.1 says "we fine-tuned Qwen2.5-Omni" without a size. This matters downstream: Qwen2.5-Omni-7B is Apache-2.0, while Qwen2.5-Omni-3B is the Qwen RESEARCH LICENSE (non-commercial, with a Β§4(b) "Built with Qwen" attribution duty that reaches models trained on its outputs). One sentence in the README would settle it permanently.
3. Minor: modeling_acestep_v15_turbo.py and configuration_acestep_v15.py in this repo carry Apache-2.0 headers (and the latter a Qwen/HuggingFace copyright line), which differs from the MIT tag on the repo. Worth reconciling. There's also a typo β "The ACESTEO Team" β in six file headers.
Happy to open a PR with the LICENSE file if that's easier. Thanks!
