## Summary

Google Cloud, with Mercor, announces Physical-Engineering's Last Exam (PLE), a benchmark of 85 long-horizon tasks across mechanical, electrical, civil and structural engineering. It releases 29 public tasks, grading tools and an open leaderboard at ple-bench.com. In tests of 14 frontier models, all scored below 50%, with the best reaching a mean of 48.3%.

## Why it matters

The benchmark tests agents on multi-file engineering projects with hard safety gates, showing where current models fall short of real professional requirements.
