A few things from the Claude Fable 5.2 launch that tell you where compute demand is heading. 1/ One Anthropic engineer gave it an empty folder and asked for an operating system. It coordinated over 1,000 subagents working around the clock for eight days, and the OS boots on a laptop. 2/ A team of 1,000 Fable agents formalised Fermat's Last Theorem in 30 hours. Anthropic's first attempt took 11 days. 3/ Over 90% of the changes merged into Anthropic's core codebase are now written by Claude. 4/ Fast mode runs up to 2.5x faster at double the token price. Speed is now something teams pay extra for. The unit of work is turning into a thousand agents running for days, and every one of them is burning inference the whole time. Doesn't look like demand for compute is slowing down anytime soon. I think most people still underestimate how much inference this kind of work is going to need
