Taste-Bench Benchmark Tests AI Agents' Long-Term Decision Taste
Understand the story
On October 18, 2026, The Decoder reported that researchers released the Taste-Bench benchmark, designed to measure AI agents' decision "taste" in long-term tasks. The benchmark works by freezing an agent's run at decision fork points in its trajectory and having the model choose between two possible paths, thereby evaluating its long-term decision-making ability. The benchmark contains 502 questions, with data drawn from coding and AI research tasks such as SWE-bench Pro and METR's MALT. According to the report, the benchmark reveals that AI agents have poor long-term decision taste. There are currently no reports on specific scores of individual models on the benchmark or subsequent improvements.
