AI power needs grow half an order of magnitude per year — beyond 1GW means nuclear
Why Decentralized AI Needs Cosmos: Greg Osuri of Akash Explains (The Interop)
“The notion is that every year the amount of power we need is growing by half an order [of] magnitude… Grok was [a] 50 megawatt [data] center — you don’t have 50 megawatt supply in a single source, so they literally are burning diesel… the next model is going to be 250 megawatt, and the model after that, the next year, is going to be 1.2 gigawatt… to get anything beyond a gigawatt you need a nuclear reactor.” — 00:39:56
Context: GPT-3 ≈ 10MW, xAI’s Memphis site ≈ 50MW; he rules out solar-only at that scale (battery cooling losses) and cites Microsoft’s Three Mile Island purchase and ~90 approved new US reactors.
