They all do it. If you ask Claude which model it is in Chinese, it says DeepSeek or Qwen.

I had Muse Glimmer (from Meta / Facebook) quoting OpenAI's safety guidelines to me, and I had Poolside's Laguna (a smaller US company) with thinking traces about obeying Chinese law.

Both of those are local models, and I didn't provide them tools to access the internet to call other models. None of this is proof of anything, but it is suggestive.

Guess they fixed it! It used to do that. But maybe try a few more times in new conversations for luck?
