About

Grok Voice Think Fast 2.0 is xAI’s flagship voice model for building real-time assistants, phone agents, and interactive voice systems that stream audio and text bidirectionally over WebSocket. Developers can configure system instructions, high or no reasoning effort, built-in or custom voices, automatic server-side voice activity detection, silence duration, idle re-engagement, playback speed, and session resumption after temporary disconnects. It accepts PCM, G.711 μ-law, G.711 A-law, and Opus audio through JSON or raw binary frames, with configurable PCM sample rates from telephone quality to 48 kHz. It supports more than 20 languages with native-quality accents, automatic language detection, natural responses in the speaker’s language, and seamless code-switching. Language hints and up to 100 key terms improve transcription of regional speech, names, products, codes, addresses, and specialized terminology, while pronunciation replacements correct spoken output.

About

Layercode is a cloud-based developer platform that makes it easy to build production-ready, low-latency voice AI agents by handling the real-time infrastructure so you can focus on your agent’s logic; it manages WebSockets, voice activity detection, global edge deployment, and voice model integrations while giving you full control over how your agent thinks, speaks, and responds. It enables natural, fluid voice conversations with sub-second response times and human-like turn-taking, offers observability tools so you can inspect calls, latency, and failures in production, and fits naturally into modern TypeScript and Next.js stacks with simple CLI and SDK support so you can receive text and send text back. With Layercode, you can avoid vendor lock-in by hot-swapping leading voice and transcription model providers, maintain complete flexibility by plugging in your own AI agent backend, and deploy voice agents across web, mobile, and phone interfaces.
