About
Grok 4.1 Fast, released by xAI in November 2025, is designed for high-speed inference at scale with a 2 million token context window for applications requiring extremely long-form context processing. It targets latency-sensitive workflows and production deployments where response speed and the ability to process very long inputs matter as much as depth of reasoning.
