Ok, but those sources or methods will not reproducibly build the artifact that are the weights of DeepSeek R1 671B, that you claimed are "opensource". Because you can't see what they actually used to build it.

DeepSeek didn't publish the exact dataset required to create it. How is having zero visibility over "the source" used to create something considered "opensource"?

That extended definition of "opensource" is useless as almost anything that isn't unique in the universe can then be declared "opensource".
