Google Deepmind's AlphaProof Nexus has autonomously solved nine open Erdős problems, including two that stumped mathematicians for 56 years, for just a few hundred dollars per problem in inference costs. Unlike OpenAI's natural-language approach, the system uses the Lean compiler to verify every proof step automatically. Still, the overall success rate sits at just 2.5 percent.

Google DeepMind's AlphaProof Nexus solved 9 open Erdős problems and proved 44 OEIS conjectures using AI-driven formal verification, with implications for crypto security.

Google DeepMind's AlphaProof Nexus solved nine longstanding Erdős problems with Lean-verified proofs, sparking debates about AI progress and its limitations.
