AI brief

A new benchmark called Taste-Bench tests how well AI agents make strategic choices during long-running tasks. Even the best model, GPT-5.6 Sol, picks the right path on just under 60 percent of simple binary questions, and thinking longer reportedly doesn't help.

Why it matters: It suggests current AI agents struggle with strategic decision-making in long-running tasks, even when given more time to reason.
