The harness is the architecture surrounding the model. How it renders context, executes actions, manages state, and decides when a task is done shapes outcomes just as much as the model itself. Harness design alone can account for double-digit swings in benchmark results and significant differences in token cost…</p> <p><a href="https://developer.nvidia.com/blog/six-agent-harness-capabilities-for-higher-model-performance/" rel="nofollow" data-wpel-link="internal" target="_self">Source</a></p>
