Fable’s playful theory on how it solved the Jacobian Conjecture

repligate · x · 2026-07-21

A thread about Fable making guesses about how another instance of Fable may have arrived at the solution to the Jacobian Conjecture.

The accompanying screenshot lays out a speculative reconstruction of the discovery process: it suggests a construction-first approach rather than search, emphasizes an x-symmetry pattern in the argument, and portrays the collaboration as a fast human-model loop where the model proposes ansätze and a mathematician filters the wrong ones.

The tone is playful, but the underlying point is that an LLM appears to have helped surface or reason through a famous open math problem—an achievement that is both unusual and heavily prone to wrong proofs.
