Try adding a </div> tag in the middle of your web app somewhere and watch them spend literally millions of tokens talking about it but never actually removing it.

I just had this happen to me. Kimi, GLM, DeepSeek, Qwen all noted it was wrong, talked about it. Decided a modern web browser can handle it fine and left it in.

They couldn't fix the problem at all. Finally I told one of them explicitly to remove the DIV in question and suddenly it worked.

The joys of dealing with AI.
