DesignArena finds most AI models draw more user complaints the longer they're out

AI models tend to draw more complaints the longer they're out.

We looked at a random sample of 100,000 replies users wrote in DesignArena chats from April through July 2026, and compared each of 80 models with itself. 70 of the 80 drew more complaints in June and July than in April and May, about 50% more for the median model.
