Rumors of Claude Fable 5 Disproving Jacobian Conjecture Sparks AI Math Frenzy

Recently, the AI community has been flooded with rumors of a mathematical breakthrough and countless memes. It is rumored that mathematician Levent Alpöge, collaborating with Matthew, found a counterexample to the 3D Jacobian conjecture using Anthropic's Claude Fable 5 model, thereby disproving it. The Jacobian conjecture has been unsolved since 1939 and ranks 16th among Smale's 18 major mathematical problems for the 21st century. This reported breakthrough quickly sparked intense discussion about the boundaries of AI capabilities and an online meme frenzy.

Core Event and Reactions

Regarding the substantive impact of AI-assisted breakthroughs, @littmath and @momkeeeeeeee pointed out that if the core goal of mathematical research is understood as solving famous open problems, then this event is highly significant. If the counterexample passes complete review, it will greatly boost optimism about AI's near-term impact on math. @pickover further confirmed that the counterexample was found in 3D space. However, due to the shocking nature of the news, many posts turned into memes. @teortaxesTex and others joked that Alpöge defeated an 87-year-old open conjecture simply by prompting Fable, while @kevinroose and @doodlestein created satirical memes mocking that AI works harder than professional mathematicians without stealing tenure credit.

Controversies and Doubts

Despite the sensation, the event is still mixed with scrutiny regarding the true mathematical capabilities of LLMs. @srushnlp and @teortaxesTex noted that if a polynomial is directly thrown at a model without context, it will still be confused by advanced math problems. Some argue that what was found might merely be a trivial counterexample undiscovered by humans for a long time, which does not mean the model possesses the ability to independently deduce complex proofs. In the coming years, when facing genuine systemic barriers, LLMs might still struggle to independently prove a major open conjecture.
