Disclaimer: I did not test this yet. I don't want to make big generalizations. But one thing I noticed with chinese models, especially Kimi, is that it does very well on benchmarks, but fails on vibe testing. It feels a little bit over-fitting to the benchmark and less to the use cases. I hope it's not the same here.
Whereas the benchmark gains seem by new OpenAI, Grok and Claude models don't feel accompanied by vibe improvement
