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.

No I haven't. And I am sure there are flaws in the guide for a nuclear bomb. But a meth lab at home is definitely doable. Would not recommend it
