Grok 4 by xAI was released on July 9, and it's surged ahead of competitors like DeepSeek and Claude at LMArena, a leaderboard for ranking generative AI models. However, these types of AI rankings don't factor in potential safety risks.

As for why Grok was consulting Musk’s posts when asked about controversial topics, the company wrote, “The model reasons that as an AI it doesn’t have an opinion but knowing it was Grok 4 by xAI, searches to see what xAI or Elon Musk might have said on a topic to align itself with the company.”

Elon Musk on Wednesday unveiled Grok 4, a new version of his X platform's AI chatbot. The update comes a day after the bot posted antisemitic content on the social media network. Musk introduced the new model in a livestream on X late Wednesday, calling Grok 4 "the smartest AI in the world."

Elon Musk's xAI startup is swimming in controversy after launching Grok 4, the latest version of its snarky AI chatbot. Last week, the company boasted that Grok 4 achieved higher scores than quite a few other large language models (LLMs) on various industry benchmarks.

According to xAI's data, Grok 4 and Grok 4 Heavy essentially beat all other models, including OpenAI's o3, Google's Gemini 2.5 Pro, and Claude 4 Opus in various common AI benchmarks, though as one Redditor noticed, the competitors have been chosen selectively, likely to make Grok look better.

In a livestream with xAI colleagues, the billionaire entrepreneur described current AI systems as “primitive” and not for “serious” commercial use.

AI owner Elon Musk made some big claims about Grok’s capability, saying it was “better than PhD level in every subject.”

AI safety researchers from OpenAI and Anthropic are criticizing Elon Musk's xAI for "completely irresponsible" safety practices.
