Being open source, I believe Chinese models are less prone to censorship, since the US corporations can add censorship in several ways just by being a closed model that they control.

It's not about a LLM being prone to anything, but more about the way a LLM is fine-tuned (which can be subject to the requirements of those wielding political power).

that's what i meant even though i could have been more precise

Yes extremely likely they are prone to censorship based on the training. Try running them with something like LM Studio locally and ask it questions the government is uncomfortable about. I originally thought the bias was in the GUI, but it's baked into the model itself.
