Description

Grok 4.6 is an advanced xAI model built for long-running agents, coding, knowledge work, interactive applications, and visual project creation. It improves on Grok 4.5 with a focus on staying with complex tasks across many steps, whether the user is researching a topic, analyzing information, working across a codebase, or building a polished application. The model was trained through a longer supplemental run that used curated model-generated reasoning data, advanced technical concepts, engineering data, and an improved training recipe. Grok 4.6 was also trained with SFT and RL across domains such as STEM, software engineering, knowledge work, kernel optimization, web development, computer-aided design, and agentic coding. It is designed to turn ambitious ideas into working projects by researching unfamiliar domains, defining application structure, building core interactions, and iterating through feedback. The model shows stronger first passes on visual and interactive projects, helping users establish structure and visual language more quickly. Grok 4.6 also demonstrates more self-testing and verification during longer trajectories. It is available through Cursor, Grok Build, the xAI API, OpenRouter, Vercel, Cloudflare, and other partners, with pricing starting at $2 per million input tokens and $6 per million output tokens. By combining frontier reasoning, agentic coding, long-running task execution, visual project generation, API access, and broad developer availability, Grok 4.6 helps builders move from idea to working software faster.

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.
