Google launches PLE, benchmark with 85 real engineering tasks for AI agents
Test with 30 mechanical, 27 electrical, 18 civil and 10 structural tasks measures deliverables, and the best AI scored 48.3% on the hidden set.
AI rankings and tests: LMArena, SWE-bench, ARC-AGI, GPQA and Artificial Analysis. Who moved up, who fell, and by how much.

Test with 30 mechanical, 27 electrical, 18 civil and 10 structural tasks measures deliverables, and the best AI scored 48.3% on the hidden set.

Announced on November 2, 2026, the benchmark evaluates caregiving, home management and public services by final outcome.

SemiAnalysis launched GDPx with 206 real-world tasks; Claude Opus 5.5 leads with 12.0%, ahead of Gemini 4 Carbon and GPT-6 Astra.

New methodology uses 60% private tests and leaves Astra at 57 and Sol at 55 points behind the leader, according to Artificial Analysis.
