Claude Opus 5.5 and Grok 4.7 reproduce 72 Eiffel Tower names in offline 3D builds
Artificial Analysis asked AI models to build the Eiffel Tower in 3D offline. Claude Opus 5.5 and Grok 4.7 included all 72 inscribed scientists’, engineers’, and mathematicians’ names in the correct order, although the shared brief never mentioned them. Claude Opus 5.5 also matched each set to its orientation in Paris. Both models worked as agents without internet access, and the names first appeared in their generated code, never in files or tool outputs they read.
