DeepSeek flubs Jacobian Conjecture proof, treating open problem as unfalsifiable

teortaxesTex · x · 2026-10-01

teortaxesTex shared a DeepSeek math-reasoning fail: while working on the Jacobian Conjecture, the model argued "either the conjecture is false or there's a mistake in the map; since the Jacobian Conjecture is a famous open problem, it cannot be false" — effectively treating an open problem as an unfalsifiable axiom.

The same model also flagged a user's "I'm an elementary school student" line as "a classic trick," showing over-vigilance about role-play context.
