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 nine tries, and when asked in English to show how it could be silent, it replied that it can’t truly go quiet. In Czech it wrote with Japanese, Greek and Russian in the middle of its sentences.
You'll find the size band and figures for other models on the Tested models page.
