Elon Musk on Wednesday teased a forthcoming male Grok companion from xAI, which already offers an anime waifu named Ani and a red panda named Rudi.

One of the new “companions,” or AI characters for users to interact with, is a sexualized blonde anime bot called “Ani."

An AI model launched last week appears to have shipped with an unexpected occasional behavior: checking what its owner thinks first.

AI explained why Grok 4 seemed to search for Elon Musk's opinions when asked about some hot-button topics.

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.”

AI safety researchers from OpenAI, Anthropic, and nonprofit organizations are speaking out publicly against the “reckless” and “completely irresponsible” safety culture at xAI, the billion-dollar AI startup owned by Elon Musk. The criticisms follow weeks of scandals at xAI that have overshadowed the company’s technological advances.

Internal docs show xAI paid contractors to "hillclimb" Grok's rank on a coding leaderboard above Anthropic's Claude.
