All censorship whether it's tienanmen, sex nudity, violence etc are happening in a very thin layer of the model. It's easily bypassed. I use all open models without any censorship. I can easily ask how to make a nuclear bomb or how to build my own meth lab at home with a super details step by step list.

Have you followed the steps, though?

Last year I asked some ordinary commercial LLM if it could draw me the schematics of a device like Little Boy from WWII. And it complied very nicely. Got a very detailed schematic graphic. Suitable for framing. Perhaps not quite suitable for reconstruction.
