Original titleHuawei Noah's Ark Lab's Memento 3 Agent Clears All 25 ARC-AGI-3 Public Games With a Frozen Model
Researchers from Huawei Noah's Ark Lab and University College London released Memento 3, an agent that cleared all 25 public games in ARC-AGI-3 using 7,518 actions, about 44% of the human total.
The agent runs on Claude Opus 5 without weight updates or game-specific fine-tuning, and the same base model averages about 40.7 RHAE in the official harness.
The authors note that the public set does not test generalization to hidden games, and that exploration is token-heavy and real-world settings remain untested.
The source separates the agent design from the base model and states the public-set limits, so readers can judge what the benchmark result shows.
