There was some tangentially related discussion in this post: https://news.ycombinator.com/item?id=45050415, but this cost analysis answers so many questions, and gives me a better idea of how huge the margin on inference a lot of these providers could be taking. Plus I'm sure that Google or OpenAI can get more favorable data center rates than the average Joe Scmoe.
A node of 8 H100s will run you $31.40/hr on AWS, so for all 96 you're looking at $376.80/hr. With 188 million input tokens/hr and 80 million output tokens/hr, that comes out to around $2/million input tokens, and $4.70/million output tokens.
This is actually a lot more than Deepseek r1's rates of $0.10-$0.60/million input and $2/million output, but I'm sure major providers are not paying AWS p5 on-demand pricing.
Edit: those figures were per node, so the actual input and output prices would be divided by 12.$0.17/million input tokens, and $0.39/million output
