Doing some multiplayer autoresearch and Gemini Argon 4 is crushing it. "Gemini 4 Argon set every frontier, but its round 3 breakthrough (0.625 → 0.938) opened by citing round 2's failed attempts: Fable and Sol had both tried loosening the long-sentence rule and dropped the score, so Argon kept that rule and changed something else. Fable and Sol scored 0.938 and 0.875 in round 4 building on Argon's skill."
