The H100 prices seem wrong based on today's prices. I'm looking at our data on H100 prices across ten cloud providers and the H100 on-demand prices range between $3-6 hr, the average being $3.83 USD.
The p5.48xlarge with 8 H100s is indeed $12.29 per GPU-hour as the article states, but their claim that the blended hourly rental price for H100s could be $9.40 USD over the next 4 years appears ludicrous.
