It doesn’t look that useful to use as it. But the approach there are investigating is clearly and well documented in plain text. Seems like a valid contribution to public knowledge to be grateful for, even if it can’t be use verbatim.
(Please note that the parent poster has edited their comment. Before edit, they implied that it was the OP who included the words “open source” in the HN post title.)
Oh, I see the links now, thanks! But they reference four different licenses, and those are the licenses just for model weights I think?
If the intention was to make something that you can only use with Llama models, stating that clearly in a separate code license file would be better IMO. (Of course, this would also mean that the code still isn’t open source.)
