Summary

An agent built on GPT-5.5 Pro successfully and autonomously generated correct disproofs of the Erd\H{o}s--Szemer\'edi sum-product conjecture over real numbers in 7 out of 8 trials. This achievement, using a three-stage prompting pipeline, marks a significant milestone for AI in advanced mathematical proof generation.

Following a recent AI breakthrough in mathematics, a new study demonstrates an agent powered by OpenAI's GPT-5.5 Pro autonomously generating disproofs for the Erd\H{o}s--Szemer\'edi sum-product conjecture over real numbers. This agent utilized a problem-agnostic, three-stage prompting pipeline: proof-plan proposal, proof construction, and review. In 7 out of 8 independent trials, the system successfully produced correct proofs, with the remaining trial identifying an unresolved gap in its argument. The generated proofs exhibited diversity, with some resembling existing unit-based constructions while others innovatively avoided units by employing $L^p$-type regions of algebraic integers. The system consumed an average of 132.4k reasoning tokens per trial. The researchers have released the code, intermediate outputs, and generated proofs, providing a transparent and reproducible case study in autonomous proof generation, free from data contamination concerns. This achievement underscores the growing capability of AI in tackling complex, abstract mathematical problems.
