Artificial Analysis says Claude Opus 5.5 and Grok 4.7 each wrote all 72 names of the scientists Gustave Eiffel placed under the tower's first platform, 18 per side, in the real order.

The models built the Eiffel Tower in 3D as agents in a sandbox with no internet access, and the brief did not mention the names. The names appeared only in code the models wrote. Artificial Analysis also says Claude Opus 5.5 placed each set of names on the side facing the same way as in Paris.
