Design Arena reports 33 AI-built websites all converging on the number 2,847

Design Arena reports that 33 websites built by AI all used the number 2,847.

The sites came from 22 models across 11 labs, each working alone on one of 28 different requests. Design Arena says that by chance, the number would appear on fewer than one site, and it presents this as evidence the models are not one model's quirk.

The report is a single post on X from Design Arena, and it gives no explanation for why the models chose the number.
