2026-03-05: We removed one problem from the benchmark, as we have determined that any solution would not meet our bar of being a publishable result in its own right. The problem page remains up: see it for more info on an AI-generated solution and subsequent human elaboration.

2026-02-24: We added two problems to the benchmark: finding a Hadamard matrix of order 668 and proving that certain “small” Diophantine equations have infinitely many solutions..
