Google introduces the PLE benchmark for real-world physical engineering tasks, featuring 85 jobs in electrical, civil, and other fields vetted by practicing engineers. The top-performing agent, Claude Opus 5.5, scored only 50.6%, primarily failing due to missed hard safety or feasibility constraints. The study highlights that existing LLM benchmarks favor textbook problems, whereas real engineering requires processing unstructured files while strictly adhering to codes.

    • The PLE benchmark includes 85 real engineering tasks requiring agents to read ~61 project files and output drawings or reports.
    • Claude Opus 5.5 leads with a 50.6% score, but only 41.3% of its design outputs met all hard constraints.
    • Developers are advised to gate engineering agents on hard safety/code limits and prioritize model selection over scaffold tuning.
