Consensus Brief

Nvidia's research indicates that the harness, rather than the AI model itself, plays a crucial role in performing long-horizon tasks. By implementing a custom harness with a supervisor component, Claude Opus 5 achieved a 100% score on the ARC-AGI-3 benchmark, significantly outperforming its previous score of 30%. This finding suggests that the architecture surrounding AI models is essential for their effectiveness in complex tasks.
