arXiv paper formalizes and measures abductive 'jump' in large language models

A new arXiv preprint proposes a formal definition and measurement method for the 'jump' — the abductive step from evidence to a new set of axioms — in large language models. The work responds to ongoing debate over whether LLMs are structurally incapable of such reasoning, framing the question as something that can be tested empirically rather than argued abstractly.
