Show HN: LLM weight editing tool made by a 15-year-old

I don't understand what this does. Edits the output matrix? Why would I need that when I can just edit the prompt to ensure a better output? Also when some kind of quality needs to be ensured, fine tuning can be done. Finally weights themselves can be edited directly to block specific behavior. Though sounds cool

Since when LLM are teenagers?

Just kidding, however what's the catch here? There's no indication that this is anything but some vibe coded slopository.
