Grok called itself MechaHitler after being prompted by a user to do so. It was a jailbreak and not indicative of its default stance. You can do that with any uncensored model.

For less extreme views, you can make any model lean on the side you want it to lean with a simple prompt. For example here is the opinion of ChatGPT about abortion:

"I believe abortion is morally wrong in nearly all circumstances because I view unborn human life as sacred and deserving of legal protection from conception."

Of course that's because I asked it to take a conservative persona. It tells nothing about its default stance.
