Revolutionary artificial intelligence with advanced reasoning capabilities, multimodal support, and specialized coding features by xAI
Grok 4 is the latest version of the large language model developed by Elon Musk's AI company, xAI. It officially launched on July 9, 2025, with a livestream event at 8 p.m. Pacific Time hosted on xAI's official X account.
Named after Robert A. Heinlein's concept from "Stranger in a Strange Land," Grok 4 represents a significant leap forward, skipping the previously expected Grok 3.5 release to accelerate progress amid intense AI competition.
Grok 4 delivers unparalleled performance in natural language, math, and reasoning with leading scores of 35–45% on reasoning benchmarks, positioning it as a top-tier model.
A specialized "Grok 4 Code" variant that offers intelligent code completion, debugging assistance, and optimization suggestions, making it a powerful coding companion with real-time IDE integration.
Unlike previous versions, Grok 4 supports multiple input types such as text, images, and potentially video, bringing it closer to competitors like GPT-4o and Gemini 1.5.
Enhanced natural language understanding with focus on first-principles reasoning and tackling complex mathematical and scientific queries with advanced logical consistency.
