TL;DR: — Zuckerberg says releasing a tunable model (without the training data set and the tools to train from it) "Open Source" — It isn't It's fascinating double-speak, because by any reasonable definition of the word source (i.e. something the model originates from), it's kept secret. The weights aren't the source the model, they're the output of the training pipeline. By that metric, Windows 95 was "open source" because you could customize the colors, the desktop background, and other parameters. But sure, why not. His "Open Source AI" is just as open as "Open AI" in the end.
