  "text": "Use Case 4: Computer Aided Design of Mechanical Iris\n\nCan an AI generate precise, functional mechanical designs?\n\nWe tasked Fugu Ultra with creating a mechanical iris in CAD, similar to a camera aperture where multiple blades must move together to cleanly open and close a central hole.\n\nWatch the animation below. We show both the detailed CAD and a simplified structural view for Fugu and the three frontier baselines.\n\nThe Results:\n\n• Fugu Ultra generated a highly functional design. The blades rotate correctly around outer pins to fully open and close the aperture.\n• Models A, B, and C failed the physical logic, resulting in gaps, weak linkages, and incomplete closure.\n\nWhen a task demands exact spatial precision and structural reasoning, relying on a single model is simply not enough.",
