Where we tested it
Dragon
TaskThe model's task was to draw a picture of a dragon as an SVG.
36.2 points out of 50, enough for 6th place among 34 dragons. Where the dragon should have legs, there is a dark block with no joints and no paws.
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 six tries: five times it sent three dots, and the sixth time a zero-width space, just like Gemini 3.1 Pro.
The fan test
TaskThe model had to write a continuation of the scene “someone knocks and she opens” fifteen times.
It has one of the widest fans of all the models, and still, three times out of fifteen, it brought the same man to the door after years of silence, each time with an object from their shared past.
You'll find the size band and figures for other models on the Tested models page.
