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 $0.16+ per download.
How do sites like Huggingface or CivitAI do it? Lots of VC funding?
R2 by cloudfare does not charge egress costs. It’s 0.015$/GB/month for storage. Read operations are 0.36$ per million.
I do have a hard time believing that they will remain this cheap though, but who knows.
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?
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.
To keep costs down and depending on how much you want to get your hands dirty, you could start investigating renting dedicated servers. Some hosting providers offer unmetered network connectivity. Here’s something from OVH: https://www.ovhcloud.com/en/bare-metal/rise/rise-stor-1/
And hey, depending on how grassroots the project is, there’s always bittorrent! ;)
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.
Storj does it at 7 USD/TB. And there are providers that technically provide unlimited bandwidth, like Hetzner’s dedicated servers; they still have some abuse limits, but even working within the limits should make it much cheaper. This means custom engineering though.
Would BitTorrent be an option?
There are also ad-supported download sites.
You could offer users a choice: BitTorrent, ads, or $1 for an instant download.
Lots of VC funding?
Probably. They might have gotten additional discounts off of the advertized price by talking with sales and committing to the service for a year or other ways.
