Description

Grok 4.1 Fast represents xAI’s leap forward in building highly capable agents that rely heavily on tool calling, long-context reasoning, and real-time information retrieval. It supports a robust 2-million-token window, enabling long-form planning, deep research, and multi-step workflows without degradation. Through extensive RL training and exposure to diverse tool ecosystems, the model performs exceptionally well on demanding benchmarks like τ²-bench Telecom. When paired with the Agent Tools API, it can autonomously browse the web, search X posts, execute Python code, and retrieve documents, eliminating the need for developers to manage external infrastructure. It is engineered to maintain intelligence across multi-turn conversations, making it ideal for enterprise tasks that require continuous context. Its benchmark accuracy on tool-calling and function-calling tasks clearly surpasses competing models in speed, cost, and reliability. Developers can leverage these strengths to build agents that automate customer support, perform real-time analysis, and execute complex domain-specific tasks. With its performance, low pricing, and availability on platforms like OpenRouter, Grok 4.1 Fast stands out as a production-ready solution for next-generation AI systems.

Description

The Grok Voice Agent API allows developers to create advanced voice agents with industry-leading speed and intelligence. Built entirely in-house by xAI, the voice stack includes custom models for audio detection, tokenization, and speech generation. This deep control enables rapid performance improvements and ultra-low latency responses. Grok Voice Agents support dozens of languages with native-level fluency and can switch languages mid-conversation. The API consistently outperforms competing voice models in human evaluations for pronunciation and prosody. Real-time tool calling and live search across X and the web are supported. Developers can integrate custom tools to enable dynamic task execution. The API follows the OpenAI Realtime specification for easy adoption. Pricing is a flat per-minute rate, making costs predictable at scale. The Grok Voice Agent API is designed for production-ready voice applications.
