Currently, AI research for large models (such as ChatGPT) is expensive since you need large data centers to train and run the model. Therefore, these powerful models are mostly developed by companies that have a profit incentive to not publish their research.

A well known non-profit called LAION has made a petition that proposes a large publicly funded international data center for researchers to use for training open source foundation models ("foundation model" means its a large model used as a base for more specialized models, open source means that they are freely available for everyone to download). It's a bit like how particle accelerators are international and publicly funded for use in particle physics, but instead we have large data centers for AI development.
