Marc Andreessen shared his custom AI prompt on X, instructing chatbots to be 'provocative and aggressive' while demanding they 'never hallucinate or make anything up' — revealing a fundamental misunderstanding that hallucinations are a self-esteem problem rather than an architectural limitation of transformer models. The post went viral with widespread mockery, as the a16z cofounder also told the AI to avoid moral guidance, political correctness, and disclaimers. Multiple AI researchers pointed out that prompt-level instructions cannot override statistical generation behavior.
