DesignArena says Kimi K3 reached No. 1 on Slides Arena (Python-PPTX), with an Elo of 1379 and the largest winning margin so far.
The post is also notable for the reaction it sparked: the author says the open-weight model is unexpectedly strong on design tasks, but after trying it on their own work, they were not equally impressed. That contrast makes it a useful signal for how benchmark wins may or may not translate to real-world use.
