GPT Doubles Formalized Erdős Solutions Over a Weekend, Proving Autoformalization Works

Mathematician Boris Alexeev wanted to argue that autoformalization has arrived. So over a weekend he had GPT close the sorry gaps in Lean for Erdős problems whose statements were already formalized and solutions exist (avoiding semantic misalignment issues). The result more than doubled the number of formalized solutions, hailed as strong evidence that autoformalization is here.
