Grok 4.2

By xAI
Model family: Grok
Grok 4.2 is commonly described as a minor revision within the Grok 4 line rather than a separately documented flagship release on xAI’s public pages. In xAI’s published materials, Grok 4 is positioned as a model with native tool use and real-time search integration, available in the Grok product and through the xAI API, with the consumer Grok experience also highlighting real-time search plus creative features like image generation and trend analysis. Based on what xAI publicly documents, the safest way to catalog “Grok 4.2” is as an incremental Grok 4-series variant label used in the ecosystem, while the official, explicitly described capability set is represented under Grok 4 in xAI’s own documentation.
Multimodal Gen 3
Released: February 17, 2026

Overview
