Anyone could comment or speculate what this enormous valuation stems from? Sources list their revenue as $150M? If true this is likely one of the biggest valuation gap I've ever seen. IMO hugging face is not something could not be reproduced, perhaps not very easily but I see its business model akin to github's. Various github alternatives exist and so will hugging face alternatives.
Huggingface is not a product, it's a community. It's the go-to place where everyone who has anything to do with open AI models gathers. You could trivially reproduce their stack, but building such a huge AI community around a single place is probably impossible by now.
