About

Grok 4.1 Fast is the newest xAI model designed to deliver advanced tool-calling capabilities with a massive 2-million-token context window. It excels at complex real-world tasks such as customer support, finance, troubleshooting, and dynamic agent workflows. The model pairs seamlessly with the new Agent Tools API, which enables real-time web search, X search, file retrieval, and secure code execution. This combination gives developers the power to build fully autonomous, production-grade agents that plan, reason, and use tools effectively. Grok 4.1 Fast is trained with long-horizon reinforcement learning, ensuring stable multi-turn accuracy even across extremely long prompts. With its speed, cost-efficiency, and high benchmark scores, it sets a new standard for scalable enterprise-grade AI agents.

About

Grok Build is xAI’s evolving coding platform that is expanding beyond a simple CLI agent into a full browser-based IDE experience. One of its standout features is Parallel Agents, which allows users to send a single prompt to multiple AI agents at once for side-by-side comparison. Users can run up to eight agents simultaneously across models like Grok Code 1 Fast and Grok 4 Fast. The interface includes a dedicated coding session view with visible outputs and context usage tracking. An experimental Arena Mode appears to enable agents to collaborate or compete, potentially ranking the best responses automatically. The UI overhaul introduces browser-style tabs such as Edits, Files, Plans, Search, and Web Page, along with live previews and codebase navigation. With GitHub integration, dictation support, and collaboration tools in development, Grok Build is positioning itself as a multi-agent AI-powered development environment.
