Elon Musk's startup xAI apologized Saturday for offensive posts published by its artificial intelligence assistant Grok this week, blaming them on a software update meant to make it function more like a human.

Elon Musk has launched xAI’s Grok 4—calling it the “world’s smartest AI” and claiming it can ace Ph.D.-level exams and outpace rivals such as Google’s Gemini and OpenAI’s o3 on tough benchmarks

Elon Musk's new AI chatbot, Grok 4, is raising eyebrows for its unusual behavior. The chatbot, released Wednesday by Musk's company xAI, sometimes searches Musk's views online before answering questions.

The latest iteration of Elon Musk's artificial intelligence chatbot, Grok 4, is drawing attention for an unusual feature: before answering some questions, it checks what Musk himself has said on the topic.

ChatGPT by OpenAI and Grok 4 by xAI (Elon Musk’s AI company) are redefining the landscape of AI conversation, information delivery, and even political ideology. Each system offers a unique approach, reflecting not only technological capability but also philosophical design.

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