“It'll really come down to geographic locality and probably a medium number of medium-sized data centers. Sorry for the whatever lack of precision there, but medium number of medium-sized data centers augmented with a small number of large data centers.”

Vahdat: AI inference does not require gigawatt-scale data center capacity
“You don't strictly need a gigawatt of capacity to be able to do useful work. You probably don't even need a hundred megawatts of capacity. It gets a little bit more interesting than that because of, let's say, co-located compute and storage and networking and …”

Vahdat: The AI industry should accept lower-reliability power delivery
“No, it is not intrinsic and we should be thinking about lower reliability power delivery overall.”

Disclosure
Vahdat: Google trades uptime for capacity in customer co-design
“Without saying too much, it's happening. I would say there's actually the co-design there with our customers at Google has been one of our sources of significant efficiency.”

Vahdat: AI scaling bottlenecks constantly rotate between labor, power, and chips
“When delivering the end-to-end, we unfortunately don't have the luxury of focusing on a single limiter. I would say very sincerely and honestly at 10 a.m. It's labor, at noon it's power, and at two p.m. It's chips every single day.”

Vahdat: Interactive AI models will require geographically distributed inference infrastructure
“So as these services become more interactive, as they become more efficient, and that, that is still going to be a journey. We're not there today. You're going to want to have geographic locality. That's also going to impact reliability, because again, you can…”

Google reached 1 GW in utility demand response agreements by March 2026
“In March, we actually hit a significant milestone in agreements with utilities for a gigawatt of demand response across our fleet.”
