Anthropic said its Claude Fable 5.2 model resolved two long-standing problems in black hole physics, with the two related papers posted to Hexagon on the 7th. One paper computes a coefficient that distinguishes the nature of a phase transition under weak-coupling conditions, a quantity left uncalculated for 23 years, and concludes from its sign that the transition is first-order. The work is theoretical rather than observational, calculating a quantum field theory that corresponds to phenomena in a gravity theory via holographic duality. The result matters because it marks a concrete, checkable advance on a problem open since 2003, and it follows the release of Fable and Mythos 5.2 alongside API price cuts. What to watch next is whether the coefficient and the second paper's results hold up under independent scrutiny and are extended to further holographic models.
