Hi, thank you for releasing this model!

I have a question regarding the licensing structure of the model.

From the README, I understand that:

• The code is licensed under Apache-2.0
• The pretrained weights are licensed under CC-BY-NC-SA-4.0
• The model license tag indicates CC-BY-NC-4.0 as the overall model license
• Additionally, the model is subject to the LLaMA model license

However, I noticed that the weights are released under CC-BY-NC-SA-4.0, which includes a ShareAlike (SA) requirement, while the model-level license (CC-BY-NC-4.0) does not include this clause.

It seems that downstream use would need to comply with the most restrictive terms among the components. In particular, the SA clause typically requires downstream derivatives to adopt the same license terms.

So I’m wondering:

1. Is the CC-BY-NC-4.0 tag intended to represent the license of the entire model, including the weights?
2. How should the ShareAlike requirement from the weights license be interpreted and enforced for downstream use of the model?
3. What is the role of the LLaMA license in this setup? Is it a binding upstream license that must be preserved or propagated in downstream distributions, and how does it interact with the CC licenses?

I would really appreciate any clarification. Thanks!
