> That's about $4000/month in bandwidth costs

You're an order of magnitude off.

45 TB per day is 1,350 TB in a month, or 1,350,000 GB.

Show me somewhere you can get a petabyte of egress inside a calendar month for 4 figures USD...

Let's suppose you even used the cheaper egress from Cloudfront rather than serving from S3 (lol @ your wallet if you serve 1 PB doing that).

The first petabyte costs an average of $0.045 per GB - $45,000.

The remaining 350 TB costs another $10,500 for a total of $55,500.

Serving off S3 directly? Yeah, that'll be more like $150,000.

Correct me if I'm wrong, but most colocation/dedicated server providers offer such prices. E.g. hetzner.com @ €1/TB, sprintdatacenter.pl @ €0.91/TB, dedicated.com @ $2/TB (or $600/month for an unmetered 1 Gbps connection).

But if you want S3/CDNs/<insert any cloud offering here>, then yeah, they're expensive.

BTW per Cloudflare ToS[0]:

Tweet does say it's a 'bucket' though.

You confused cloudfront with cloudflare

True, I'm not that familiar with Amazon offerings (only ever used it for Windows GPU instances) and reading too fast got me. Too late for an edit.

Cloudfront is a premium service. It's not a good baseline for bandwidth prices.

Backblaze will send out data for 1 cent per GB, or $13,500. BunnyCDN apparently starts at 1 cent per GB in North America and Europe, and has a fewer-PoP plan that would be $5,550. And let's be fair, you don't need many points of presence for half-gig neural network models.

The other option is buying transit. Let's say we want the ability to deliver 80% of the 45TB in 4 hours as our peak rate. Then we need 20gbps of bandwidth. That's around $9,000 in a big US datacenter. Aim for a peak of 6/8 hours and it's $6,000/$4,500.

How the hell are they paying that bill then??

ingress/egress is usually free within the region AFAIR

Only if both ends of the request are on AWS.

I may be a little off, but definitely not by an order of magnitude. Even high-end hosting at a provider like Akamai can be under $10/TB-mo for such large volumes. And since you don't need any of the hundred value-added services that Akamai, Cloufront, Fastly etc. offer, the budget providers can go a lot lower than that.
