Anthropic says Claude Fable 5.2 closed two open problems in holographic duality: whether black holes form abruptly in very small universes, extending a 1983 result through a method proposed in 2003 and never finished, and the exact limit of the spinless modular bootstrap, now given as approximately 9.1266 against a previously known range of 8.503 to 12. Both are preprints deposited by Anthropic, neither has been peer reviewed, and in both cases the confirming second computation came from another Claude model.
