Please add a LICENSE file to the weights repo (and clarify the Qwen2.5-Omni variant)
Hi — 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 — 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 §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 §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 — "The ACESTEO Team" — in six file headers.
Happy to open a PR with the LICENSE file if that's easier. Thanks!
Hi, and thanks for ACE-Step 1.5. I'm a solo indie developer and I used the acestep-v15-turbo weights (DiT, VAE and text encoder, run locally) to make a few short sound stings for a game I plan to release commercially on Steam.
I'm adding to this post because I need a clear answer before release. The model card and the Hugging Face tag say MIT and "Commercial-Ready", but this repo has no LICENSE file. Could you confirm in a comment, or by adding the MIT LICENSE or a README line, that the MIT grant covers the model weights in this repo, and that audio generated with them can be used commercially?
A short written confirmation would be enough for me to keep with my release records. Thank you.
- will add MIT LICENSE for it soon.
- ACE-Captioner/ACE-Transcriber was fine-tuned from Qwen2.5 Omni-7B.
- can be used commercially
Thank you for the reply and for the clarification on the captioner. Once the MIT LICENSE file is in the weights repo, could you also add a line to the README confirming that MIT covers both the weights and audio generated with them? That would give commercial users, including me with a Steam release, something concrete to point to. Thanks again!
Thank you — that settles all three questions. Knowing the Captioner/Transcriber come from the 7B removes the licensing ambiguity for downstream ports like mine. And thanks in advance for adding the MIT LICENSE file to the weights repo; that will close this out completely.
