Opus 5 clears ARC-AGI-3 levels after figuring out the rules on level 1

A demo run of Opus 5 on ARC-AGI-3 shows a characteristic pattern: it flails on level 1 while learning the rules, then clears levels 2 and 3 without trouble.
By level 4 it pauses to try a few hypotheses, solves the problem, and keeps going smoothly. The post is framed as one of the model's most impressive runs on the public demo.
