[1. Creator’s description of the task] We asked 5 top AI models to design, engineer and 3D print a bridge to with the goal of holding the most possible weight. [2. Creator’s summary of the design constraints] Each bridge had specific parameters. It had to span 2 feet, use a maximum 500 grams of filament, and it had to be under 18 hours of printing time. We specified what type of weight and where we would place it on the bridge.
