It might be a mistake since it's different from what's stated in their readme:
https://github.com/meta-llama/llama-models/blob/main/models/...
(which is referring to the license of Meta Llama 3.2)
https://github.com/meta-llama/llama-models/blob/main/models/...
(which is referring to the license of Meta Llama 3.2)
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.)
