AI agent evaluation should focus on tool-call trajectory, not just final answers

By PulseAugur Editorial · [1 sources] ·

The author argues that evaluating AI agents solely on their final output is a flawed approach. Instead, they propose focusing on the agent's tool-call trajectory, asserting that this provides a more accurate measure of performance, especially for stochastic agents. The recommendation is to track pass@k metrics rather than pass@1 and to use pinned seeds with temperature set to zero for regression suites to monitor eval-set drift. AI

IMPACT This perspective could influence how AI agents are tested and benchmarked, potentially leading to more robust and reliable agent development.
