I think sharing your intellectual property is a function of how much personal investment you have made and how much $$$ you could potentially earn by keeping it closed.
Right now, I see that OpenAI has a lot of bucks to make off of these AI models, and they have invested a lot of $$$ in R&D as well (as well as their investors). So it just doesn’t make sense for them, I can understand their position.
But there are other initiatives that are open from the get-go, and are totally community driven and crowdsourced. In this version, you would expect it to be “free” and “transparent”, and they normally are.
But yeah, get rid of the GitHub dependency!
