Grok 4 xAI Elon Musk
Elon Musk’s xAI has launched its latest AI model, Grok 4, to compete with existing models like OpenAI’s ChatGPT and Google’s Gemini. Musk made the announcement during the livestream event via xAI’s official account on X(formerly Twitter). Talking about the latest update, Musk claimed that Grok 4 is the “smartest AI in the world.” Musk said that the AI platform has a PhD-level expertise across all subjects, emphasising its advanced reasoning and coding capabilities. Over 1.5 million viewers attended the event.
According to a report by TechCrunch, Grok 4 has secured 25.4% on the Humanity’s Last Exam, comprising over 2,500 questions on various subjects like math, science, and linguistics. The company said Grok 4 could solve about a quarter of the text-based questions involved. When equipped with tools, Grok 4 Heavy achieved a score of 44.4%. Additionally, it has scored 16.2% on the ARC-AGI-2 test, which assesses visual pattern recognition, outperforming the performance of the Claude Opus 4. Here’s how much a Grok 4 subscription costs.
The Grok 4 standard subscription plan starts at $30 (roughly Rs 2570) per month. Additionally, users can also opt for the SuperGrok Heavy plan at $300 (roughly Rs 25,700) per month, offering early access to new tools and a multi-agent version of the model. The company also extended five new voices for Grok’s voice mode.
The latest update was introduced just within 24 hours after xAI was forced to remove inappropriate Grok 3 posts from X that contained antisemitic comments.
For those who are unaware, Grok’s automated responses included antisemitic content, which caught the attention of several users. The post also faced public backlash and the temporary suspension of xAI.

Grok 4 is said to be trained on xAI’s Colossus supercomputer to offer stronger logical reasoning and text generation. The AI platform is designed to write, debug and explain code more efficiently. Additionally, it is expected to support images as well as video along with text, similar to OpenAI’s GPT-5o and Google’s Gemini 2.5 Pro.
Furthermore, Grok 4 features DeepSearch to provide up-to-date results during chats without having the need to open a separate tab or browser.
