AI, made a splash with the release of Grok 4, and the announcement of a new ultra-premium subscription tier, SuperGrok Heavy.

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.

XAI’s Grok 4 AI chatbot launched Wednesday appears to consult Elon Musk’s views when asked its opinion on some controversial matters.

As Grok fired off replies on X praising Hitler, the chatbot's parent company also recently got permission to emit 97 tons of carbon monoxide per year to keep it running.

Grok 4 marks a significant advance in reasoning, scientific problem-solving, and real-time information access. Trained on over 200,000 GPUs using xAI’s Colossus supercomputer, it achieves ten times the reasoning power of Grok 3. The model uses reinforcement learning to tackle complex and novel problems across multiple subjects.

Musk's announcement comes hours after xAI debuted its latest flagship AI model, Grok 4. The 54-year-old discussed the recent innovation during a nearly hour-long livestream shared on xAI's X page, during which he did not mention the chatbot's integration into Tesla vehicles.
