Don't you run into it sometimes outputting a few Chinese characters, or Cyrillic, for no apparent reason? I fear it writing some nonsense in the code or the terminal. DeepSeek V4.1 Flash doesn't seem to do that.

That hasn't happened with GLM 5.3 yet but with DS 4.1 Flash it did happen and it also had a tendency to loop.

To be fair even OpenAI's and, to a lesser extent, Anthropic's models do that sometimes
