A new benchmark called PLE has been developed to assess the capabilities of frontier language models in performing professional physical engineering tasks. Unlike existing benchmarks that focus on textbook questions or isolated tool use, PLE comprises 85 long-horizon, agentic tasks across electrical, civil, structural, and mechanical engineering, requiring models to produce realistic, billable engineering deliverables. Evaluations of current leading LLMs show they achieve an average score of only 50.6%, consuming significant computational resources, highlighting a substantial gap between their current abilities and autonomous physical engineering design.
