Opus 5.5 is crazy, and this is yet another proof. 3 moves. That's all it needed to solve the Rubik's Cube and beat GPT-6 Sol, Jev and Laya, with the same limits for all four models: 20 moves or 5 minutes. Opus 5.5 solved it in 1m 12.87s with the perfect 3 moves. GPT-6 Sol made a wrong first move and ran out of time after 4. Jev and Laya both used all 20 moves without solving it. https://x.com/aimlapi/status/2103507327999529154/video/1
