Elon Musk's xAI has launched Grok 4, an AI model now available for free globally, aiming to compete with OpenAI’s GPT-5. The new model features Auto and Expert modes for improved user interaction and includes the controversial Grok Imagine video generation tool. Additionally, xAI plans to introduce ads in the Grok interface to manage operational costs.

Elon Musk's xAI is set to launch Grok 4, skipping the previously planned Grok 3.5, with new features focusing on enhanced natural language processing, math, and coding capabilities. The Grok 4 model will also introduce features for vision and image generation, allowing developers to utilize it as a coding companion through the xAI Console.

xAI's Grok 4 model, anticipated for release after July 4th, has not yet launched, though references to internal versions suggest ongoing development. Recent documentation indicates Grok 4 may achieve a significant 45% score on the Humanity last-exam benchmark, surpassing previous leaders and positioning xAI for competitive advantage against rivals like OpenAI and Google. The urgency for release is heightened by the fast-paced AI landscape, with expectations for Grok 4 to debut imminently.
