Anthropic has restricted xAI's access to its Claude models used for coding, a move aimed at reducing competition. xAI cofounder Tony Wu acknowledged that while this will impact productivity, it will also drive their team to develop their own coding solutions.

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.
