Holy crap, Does huggingface charge for bandwidth if you're downloading 45 terabytes??
I believe they are hosting it on Cloudflare who doesn’t charge for egress
More specifically, Cloudflare R2 doesn't charge for egress, and Cloudflare doesn't charge for egress to members in the Bandwidth Alliance which include Azure, Google Cloud, Oracle, Alibaba Cloud, and others, though critically not AWS.
They very much do charge egress fees elsewhere.
Fun trivia: downloading 45TB costs about $60, according to Cloudflare.
That's what Cloudflare charges. It costs them around 6 cents.
Wish I could say I'm surprised you're getting downvotes. Carrier costs are some of the lowest costs for hosting providers. Yet that fact seems to elude a majority of the community here.
