Elon Musk announces Grok 4.20 launch this week

X owner and xAI founder Elon Musk said that a new version of the Grok model, Grok 4.20, will be released later this week. According to him, the update will represent a “significant improvement” over the current 4.1 version.

Specific details about the changes have not yet been disclosed. However, users can likely expect further gains in accuracy, faster performance, and potentially expanded functionality. Previous Grok updates focused on improving response quality and generation speed.

Grok is positioned as a competitor to other leading AI models and is integrated directly into the X platform. The model is known for its built-in “sense of humor” and real-time access to data from X. Its core capabilities include answering questions, writing code, generating images, and analyzing social media trends.

Earlier reports also revealed that SpaceX has integrated a customized version of Grok, dubbed “Spok,” into its internal processes — highlighting the growing role of xAI technologies across Musk’s ecosystem of companies.
