8 × H100 cost $16,878 a month. The cheapest API (Azure) charges $0.275 per 1M blended tokens, so the GPUs only pay off above 61.4B tokens a month: the box must serve 23.4K tokens a second, every second.

GPU price: cheapest on-demand offer per GPU-hour × 730 hours. No throughput is assumed: it depends on the model size, precision, batch size and serving software, so measure yours. Power, storage, egress and engineering time are not included.
