Yes and a devops engineer to manage an even moderately complex cloud deployment is an average of an extra $150k/yr. I don't know where this "cloud labor skill, knowledge, experience, and time is free" thinking comes from.
8, 80k, or 800k GPUs depending on requirements and load - the point remains the same.
This is 6 month of salary of one average developer's salary there. And BTW they are likely doing inference on 100s or 1000s of GPUs, not just 8.
