It is cheaper than GPT-5.6 and Anthropic's models. But then on coding agents specifically (if we take artificial analysis, at least - I'm sure there's a better meta-review you could do) Grok-4.5 scores better and is 20% cheaper. Of course there are other reasons you might prefer Kimi to Grok. But still, if coding is the main concern, is Kimi opening up somewhere new on the cost-capability Pareto frontier? Not necessarily.
