JuliaHub has released a comparative study evaluating the performance of OpenAI's GPT-5.6 family and Anthropic's Claude Fable-5 models on physical AI tasks. The evaluation focused on the models' ability to correctly encode physics in simulations, a critical factor for engineering applications where real-world accuracy is paramount. Using their Dyad AI agent harness with consistent parameters, JuliaHub conducted 52 graded runs across five distinct problems, including a challenging NASA flight vehicle simulation, to determine which model excels in this specialized domain.
