I’m looking at starting a service that involves hosting a lot of LLM models, which are often going to be 16GB+ (compressed). I did a bit of searching for cloud storage providers with cheap egress, and the cheapest I could find is $0.01 per GB, which would still be $0.16+ per download.

How do sites like Huggingface or CivitAI do it? Lots of VC funding?

    If the files are not going to be changing much, then what is typically done is to use a CDN service (e.g. Cloudflare, Akamai, Fastly). The idea is you have an “origin” which could be any old server which serves your files over HTTP (even a VPS running nginx). The CDN is configured to proxy requests to the origin, building up a cache of the files it serves. The CDN can serve files from cache on their own (very large) infrastructure. See also What is a CDN?

      So I got curious and wondered how HuggingFace hosts their files. It’s AWS CloudFront:

      That’s true, but I just checked a few CDNs and you won’t find one for less than $.01/GB. The lowest I found was $.03/GB.

          I was considering this. The hosting provider we use for model training runs doesn’t charge for ingress/egress. Their storage costs would eat us alive though haha. OVH looks much more promising.
