GPT Doubles Autoformalized Math Proofs in Weekend Test

Boris Alexeev demonstrated a breakthrough in autoformalization using GPT. Addressing a bottleneck where formalized Erdos solutions were tapering off, he tasked GPT with completing the proofs for problems where the statements were already formalized (avoiding semantic misalignment). The experiment successfully more than doubled the number of autoformalized solutions, providing strong evidence that the era of effective autoformalization has arrived.
