The one metric AI coding agents can't fake: human hours
Cognition Labs built the first automated system to estimate how many human engineering hours each Devin session saves. The model reaches R² 0.70 but deliberately underestimates. The deeper challenge: converting session traces into defensible ROI numbers remains unsolved.

Why GPT-5.5 dominates a benchmark that tests how agents improve themselves
EvoPolicyGym isolates a critical but understudied capability: an agent's ability to refine an executable policy through repeated feedback-constrained edits. The benchmark reveals GPT-5.5 as the strongest performer across 16 environments, and provides trajectory-level diagnostics that expose how different agents allocate budget and convert feedback into tuned parameters.
