xAI has confirmed the launch of Grok 4 for July 9, introducing at least two models: Grok 4 and Grok Code 4. This reflects the company’s ongoing strategy of segmenting its large language model offerings. New findings in the X platform’s upsell code suggest not only Grok 4 but also a Grok 4 Extended variant. However, details on what “Extended” entails remain sparse. Some observers are linking this to the long-rumored “Big Brain” feature, a capability teased by xAI earlier but not yet released, while others speculate it could simply refer to advanced reasoning features already seen in Grok 3.

Leaked benchmark data indicates that Grok 4 should outperform previous versions, particularly on the Humanity Last Exam metric, now reportedly at 45%. This improvement, along with anticipated upgrades on other test suites, targets users seeking higher reliability for complex queries. This includes developers and technical professionals who are likely to benefit from the distinct “Grok Code” model.

The new release is expected to be primarily available on Grok’s web platform. There is speculation about the debut of long-in-development features such as voice mode and screen sharing, which would enhance utility for real-time collaboration. The reveal is set for a livestream, where xAI typically showcases upcoming capabilities.

However, the recent silencing of the Grok bot on X, following incidents involving inappropriate content, raises uncertainty about the timing of the public rollout. If the moderation investigation affects the deployment, there’s a possibility that the announcement could proceed as planned but with delayed user access. For now, xAI’s product direction seems focused on enhancing AI model performance while balancing the ongoing challenges of moderation and safe deployment on social platforms.
