OpenAI's GPT-5.6 model has reportedly solved the 50-year-old Cycle Double Cover Conjecture in graph theory within an hour. The model utilized 64 sub-agents and a detailed 700-word prompt that focused on defining success criteria and boundaries rather than dictating specific problem-solving steps. This approach allowed the model to explore multiple solution paths dynamically and incorporate independent review mechanisms, showcasing advanced capabilities in complex mathematical reasoning and prompt engineering.
