Grok 4 · fastrouter

Grok 4, launched by xAI in July 2025, represents a significant leap in large language model development. Building on earlier versions like Grok 3 and the original 2023–24 models, Grok 4 introduces several key enhancements aimed at performance, versatility, and real-world application. It features an extended context window of up to 256,000 tokens, enabling it to process long documents, codebases, or conversations with greater depth and continuity. The model demonstrates strong performance in advanced reasoning tasks, including mathematics and programming. Its architecture supports multimodal input, with capabilities for vision and voice currently in development, and introduces advanced voice interaction with faster response times and more natural flow.
