Tech billionaire Elon Musk’s artificial intelligence (AI) company xAI has just launched its latest AI model, Grok 4, touted as the world’s most powerful AI. The official launch of Grok 4 took place on Wednesday with a livestream announcement. The new Grok AI version is already accessible via the Grok app, compatible with both Android and iOS devices. The Grok 4 launch also introduced the more advanced Grok 4 Heavy model and a new premium subscription plan, SuperGrok Heavy, priced at $300 (approximately ₹25,200) per month. Such high-tier plans are primarily designed for users with intensive AI needs, including researchers, developers, and companies within the AI field. The capabilities of the new Grok 4 model are expected to face rigorous testing with the anticipated rollout of ChatGPT 5 later this year. Elon Musk, on X, highlighted Grok 4’s coding prowess, stating, “You can cut & paste your entire source code file into the query entry box on http://grok.com and @Grok 4 will fix it for you! This is what everyone @xAI does. Works better than Cursor.”
Key Points About Grok 4:
