The same model scores 30% or 100% depending on what you wrap around it

Nvidia says the same model scores 30% or 100% on ARC-AGI-3 depending on its harness

Claude Opus 5 cleared all 183 levels wrapped in Nvidia's AVO system, against 30% on its own — a vendor-run result on a public benchmark, not yet independently reproduced.

• Nvidia reports that Claude Opus 5 inside its Agentic Variation Operators harness scored 100.00 RHAE across all 25 public ARC-AGI-3 environments, completing all 183 levels.
• The same model scored about 30% without the harness, according to Nvidia's account — the model was not retrained or changed.
• AVO pairs a main agent that inspects, plans, implements and evaluates using persistent memory with a supervisor that redirects it when progress stalls.
• It used 6,624 environment actions against VISTA's 7,542 on the same levels, roughly 12% fewer, though Nvidia says this was not a controlled ablation because the two systems differ architecturally.
