There is still a large difference between an AI being able to cite it's claims, and having the original training data and exact code and process in which to convert the training data into the weights used in inference.

If you cannot re-create the weights and model used for inference, a release's value is somewhat limited vs releases where the inference model can be re-created. (It's kind of like the limited value of scientific papers where the results cannot be reproduced due to a lack of detail)
