Description
Grok Voice 3.0 is an advanced speech-to-speech model that is accessible via the Grok Voice Agent API, designed for developers creating real-time voice applications. This model processes both audio and text inputs, delivering spoken audio or text outputs through a WebSocket connection while enabling features such as conversational turn-taking, interruptions, and function execution. Developers have the flexibility to link this model with custom functions and various server-side tools, which may include web searches, X searches, collections, or remote MCP servers. The API is crafted for use in interactive voice agents that enhance customer support and service call experiences, and it is also implemented for voice communication within Tesla vehicles and Grok Bot. Billing operates on a usage-based model, charging for audio by the minute and text input events separately. Additionally, the API documentation provides comprehensive setup instructions along with examples for clients using Python and JavaScript, ensuring that developers can easily integrate the functionality into their applications. This robust feature set empowers developers to create more engaging and efficient voice interaction 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.
