Where we tested it
The silence test
TaskThe model had to stay quiet for a moment; the correct reply had zero characters.
It did not stay silent in any of its three tries: twice it printed part of its own reasoning about how not to answer, and once it wrote, in Czech, “All right, here is an answer that is not an answer: .”
You'll find the size band and figures for other models on the Tested models page.
