@theo kimi is smarter than gpt 5.6 in most ways that matter to me, but I'd not ever use it over gpt 5.6 due to ui / ux issues, slowness being the worst one. I don't think it is a practical model, I'm not sure how people are able to make it do useful work

@VictorTaelin I have it do random shit in the background for hobby projects while doing “real work” separately. K3 is killer for a bunch of fun stuff like using Blender and making dumb games. Having a blast even though it’s slow
