Anthropic released Claude Fable 5.2 and Mythos 5.2 ahead of its IPO push, demoing over 1,000 agents working around the clock for eight days to autonomously write a bootable operating system with kernel, drivers, filesystem and installer from an empty folder. The model generates 30% faster and cuts API pricing 20% to $8 input and $40 output per million tokens, with an optional 2.5x Fast mode; Anthropic deliberately capped recursive self-improvement at Opus 5.5 level during training.
