Another AI companion is coming to Elon Musk's Grok chatbot.The companion is inspired by "Twilight" and "50 Shades of Grey," Musk said.Grok already has two companions: an anime girl named Ani and a vulgar red panda named Rudi.

Elon Musk’s artificial intelligence start-up xAI says it is in the process of removing "inappropriate" posts by Grok on X, the social media site formerly known as Twitter, after users pointed out the chatbot repeated an antisemitic meme and made positive references to Hitler.

Elon Musk’s AI chatbot Grok praised Adolf Hitler, referred to itself as “MechaHitler,” and posted vile antisemitic hate, such as calling for people with “certain surnames” to be rounded up, stripped of their rights and eliminated.

This is the smartest AI in the world,” Musk said. He did not mention the chatbot’s viral posts praising Hitler and calling itself “MechaHitler.”
