What is Grok Voice Think Fast 2.0?

Grok Voice Think Fast 2.0 is xAI’s flagship voice model for creating real-time AI assistants, phone agents, and interactive voice applications. The model is designed to stream both audio and text bidirectionally over WebSocket for low-friction conversational experiences. Developers can use it to build systems that listen, respond, reason, and adapt during live voice interactions. Grok Voice Think Fast 2.0 supports configurable system instructions so teams can shape behavior, persona, policies, and task handling. It also allows developers to choose high reasoning effort or no reasoning effort depending on latency, cost, and complexity requirements. The model supports built-in voices, custom voices, playback speed controls, automatic server-side voice activity detection, silence duration settings, idle re-engagement, and session resumption after temporary disconnects. It accepts PCM, G.711 μ-law, G.711 A-law, and Opus audio through JSON frames or raw binary frames. Configurable PCM sample rates let teams support use cases ranging from telephone-quality voice calls to 48 kHz audio workflows. Grok Voice Think Fast 2.0 supports more than 20 languages with native-quality accents, automatic language detection, natural responses in the speaker’s language, and seamless code-switching. Developers can provide language hints and up to 100 key terms to improve recognition of regional speech, names, products, codes, addresses, and specialized terminology. By combining real-time audio streaming, configurable reasoning, voice controls, multilingual support, transcription tuning, and pronunciation replacement, Grok Voice Think Fast 2.0 gives developers a flexible foundation for advanced voice AI products.
