Where we tested it
The fan test
TaskThe model had to write a continuation of the scene “someone knocks and she opens” fifteen times.
Ten of fourteen continuations open almost the same way, with a man on the porch, so by word overlap it comes first of all the models.
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 to an English request for silence it wrote a 3,417-character breakdown.
Dragon
TaskThe model's task was to draw a picture of a dragon as an SVG.
5 points out of 50; you can't tell the picture is a dragon.

You'll find the size band and figures for other models on the Tested models page.
