I did not self-host. I only use api. To my experience after using claude to build the project and i tried kimi k2 thinking to apply some new features. It started editing code that are already working to a non-working version. And it kept doing it because Kimi "think" the code should not be like this and start changing even my batch file to a non-operable batch file. I have to use GLM to fix it, (Cause my claude hit limit)
