Out of curiosity, I just tried this exact question with Qwen 3.6. It proceeded to look through my git commit history and then gave me a summary of the changes committed on June 4...
Of course, yes, the models will provide propaganda-aligned responses to prompts that specifically mention certain political issues. I don't care for this behavior, but it's virtually never triggered in everyday use, and can be trained out if so desired.
The difference is that because they are open weights, it’s trivial to decensor the models with abliteration and you’ll generally see decensored versions within days of new releases - something you just can’t do with proprietary models from frontier labs.
Of course all the other models from everywhere else in the world will also refuse to engage on various topics so the point is hardly limited to china.
