We asked AI models to build the Eiffel Tower in 3D, offline. Two of them added all 72 scientists' names to it, in order, from memory

We did not expect this. Every AA-3D model got the same brief of about 200 words, on the tower's shape, lattice, platforms and lighting. It never mentions the names.

Gustave Eiffel put the names of 72 French scientists, engineers, and mathematicians under the tower's first platform, 18 on each side. Claude Opus 5.5 and Grok 4.7 wrote all 72, with each side in the real order.

Claude Opus 5.5 also put each set on the side that faces the same way in Paris.

Each model built its scene as an agent in a sandbox with no internet access. In both runs, the names first appear in code the model wrote, never in a file or tool output it read.

Congratulations to @spacexai, @elonmusk and @AnthropicAI on two seriously knowledgeable models
