Nvidia's Harness Takes Opus 5 to 100%

NVIDIA’s Agentic Variation Operators harness took Claude Opus 5 from a roughly 30% standalone ARC-AGI-3 score to 100.00 RHAE across all 183 public levels, according to NVIDIA’s AVO results. The system adds persistent memory, iterative tools, and a supervisor that redirects stalled work; NVIDIA says it used 6,624 environment actions, about 12% fewer than another Opus 5 system. Builders should benchmark the harness around a model, not just the model, as our earlier agent-cost analysis showed.
