Grok Voice Think Fast 1.0

xAIProprietaryPending Human Review

Grok Voice Think Fast 1.0 is xAI’s reasoning-enabled spoken-dialogue model. It combines low-latency speech interaction with reasoning and tool use for voice assistants. The model can answer spoken questions and take multi-step actions through application tools, so it is distinct from speech transcription or standalone text-to-speech. The first version adds reasoning while maintaining conversational responsiveness. Its parameter count and detailed architecture are not disclosed. Real-time latency and interaction quality also depend on transport, audio capture, and the surrounding application.
