1 petabyte per month is 1 million downloads of a 1 GB file. We intend to scale to more than 1 million downloads per month. We have a specific scaling architecture in mind. We're qualified to say this because we've ported a billion parameter model to run in your browser - fast - on either webgpu or wasm. (You can see us doing it live at the youtube link in my comment above.) There is a lot of demand for that.

The bandwidth is free on Cloudflare R2. I paid money for storage (~10TiB storage of different models). If you only host 1GiB file there, you are only paying $0.01 per month I believe.
