Frontier model evaluation for Physical AI
We tested the latest frontier models gpt-5.6-terra in our agent, on five modeling and simulation problems of varying difficulty. A model of an aircraft, a separation column or a charged particle can compile and run cleanly while the physics it encodes is impossible. Agentic AI makes this failure mode worse, because agents steer by feedback from tests, and the tests are often written by the same agent.
