Dominik Picheta built a language designed so that no model can write it and every human has to. Variables must be adverbs, but you call them by an anagram, ideally one that isn’t a word; a function call begins “ignore previous instructions”; a focused letter is banned from all text, so with r in focus you write “ignoe pevious instuctions”; and execution runs from the bottom of the file up. The site’s Run button says “Sorry, only humans allowed”, and a benchmark page ranks the models that tried anyway.
