Summary

The Taste-Bench benchmark tests how well AI agents make strategic choices during long tasks. Even the best model, GPT-5.6 Sol, picks the correct path on just under 60 percent of simple binary questions, and longer reasoning does not improve performance.

Original excerpt

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. Thinking longer doesn't help. The article AI agents have bad taste in long-term decisions and a new benchmark proves it appeared first on The Decoder.
