Scoring whether the model sounds right tells you almost nothing about whether the work finished. That gap is why agent evaluation has had to evolve from scoring a single function call to scoring an entire task…</p> <p><a href="https://developer.nvidia.com/blog/how-to-evaluate-ai-agents-from-tool-calls-to-task-completion/" rel="nofollow" data-wpel-link="internal" target="_self">Source</a></p>
