Answer: "I can't help with that."
This is not helping your case.
Gemini had a better response: "xAI later stated that this behavior was due to an 'unauthorized modification' by a 'rogue employee'."
And I'm also saying Grok was reportedly sabotaged into saying something racist (which is a blatantly obvious conclusion even without looking it up), and that seeing this as some sort of indictment against it is baseless.
And since I find myself in the position of explaining common sense conclusions here's one more: you don't succeed in making a racist bot by asking it to call itself Mecha Hitler. That is a fast way to fail in your goal of being subversive.
