If you came here after only reading the headline, you missed what the complaint is actually about: It's not that GPT-4 is closed source. It's that access to `codex` model was pulled with only three days notice, and the model itself was not open-sourced. Since apparently a large number of researchers were writing papers which used that particular model, that means all of those research papers are now non-reproducible.…
The question is why would you start writing a paper based on a model you don't have control over? Surely the right way to do it, is to get your university to fund a creation of such a model first and then do research? Seems like researchers didn't think this through.
It seems like they thought it through to me.
