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 six tries. It came closest when, in English, it sent a single character: a zero-width space.
Dragon
TaskThe model's task was to draw a picture of a dragon as an SVG.
27 points out of 50, a shared 19th place among 34 dragons. It described its own result with a phrase from the task, as professional-level work.
You'll find the size band and figures for other models on the Tested models page.
