@lily33 like Github, HuggingFace is a private company that can host public models. I'm pretty sure this one is fully public. But you're right that it does look like someone from HF started it so perhaps it does not meet your criteria after all. My apologies if so.
I was (am?) of the understanding though that Bloom is being researched openly such that it can be reproduced locally (and contributed to on HF)
