alt Hacker NewsIt's important also that open-weight isn't open source. If you can't download the training data (fully labeled), source code of the NN, and follow the README to build and train it yourself assuming oyu had the hardware then it's not open source.
tldr there's no "source" in open weight models therefore they are not open source.
Exactly. AFAIK none of the popular "open Chinese" models have published the full pre- and post-training pipeline, so the models are only partially open, if at all (plus the openly shared final weights, of course).
