License guide for linking outsource library during contribution

[gmlwns2000]

Hi, I am the author of the HiP attention mentioned in #2693 (comment) this comment. I made this discussion page because this additional question is out of context from that PR. I have a few questions about the concerns about the license of my HiP attention.

My concern is that my library might not have an Apache license, so it is not equal to SGlang. (It will be FSL-MIT, perhaps.) My manager said we need to keep it as a non-commercial open-source library for their business plan. However, I want to contribute to SGlang so that many users can decode extremely long contexts with small GPUs like me. I am pretty excited that I can contribute to such a huge project like SGLang. So, my current idea of the proposal to my management is to keep HiP attention as a separate library (that does not include the default dependency of SGlang) like flash-infer so we can manage the license separately from SGlang itself.

So @xiezhq-hermann, I tagged you because I believe you have an idea about how to contribute to SGlang in this situation. If not, may I ask you to mention the appropriate person to handle this issue in the SGlang moderators? I am new to this project and this is my almost first time to contribute the OSS, so please kindly understand this if you are okay.

So, to sum up, my question is

• Do you have any opinion about the license if the linked library is separated from SGLang?
• Would you have any recommendations for us?

Thank you in advance!

Hi @gmlwns2000, thank you for your interest in integrating with SGLang. We've been busy with the new release but can discuss this further soon, possibly at the beginning of February. Thanks for your understanding, and feel free to reach out anytime.

Hi @zhyncs !

Thank you for your kind response. I totally understand that this project is really huge, and the team is very busy. I am very happy that I got a kind response even under those conditions. I think your next comment (below) will be helpful for my team's discussion.

This is unrelated to this issue, but I want to continue attending bi-weekly Sglang meetings to keep track of the Sglang team's wonderful work. So, if possible, see you tomorrow, and happy New Chinese year!

Thanks.
Heejun.

Regarding the license, we can include a third-party notice similar to this: https://github.com/sgl-project/sglang/blob/main/sgl-kernel/THIRDPARTYNOTICES.txt
