About
Boson AI provides voice agents powered by foundation audio models, built to run in business workflows and learn from every call. Higgs Realtime enables live voice agents for support lines, sales calls, and product assistants that listen, reason, call tools, and respond in real time with low latency and natural speech-to-speech interaction. Higgs Audio and Avatar extend these capabilities with text-to-speech, speech-to-text, voice cloning, sentiment detection, and avatar generation, producing natural speech while understanding tone, emotion, and intent. The models support high-accuracy multilingual speech recognition, real-time translation, and expressive voice generation, while sentiment signals can improve routing, analytics, and context-aware agent behavior. Designed for real-world production, the platform emphasizes quality, latency, reliability, and flexible deployment across managed and self-serve environments.

About
Grok Voice 3.0 is a speech-to-speech model offered through the Grok Voice Agent API for developers building real-time voice applications. It accepts audio and text and returns spoken audio or text through a WebSocket session, supporting conversational turn-taking, interruptions, and function calling. Developers can connect the model to custom functions and server-side tools, including web search, X search, collections, and remote MCP servers. The API is intended for interactive voice agents such as customer-support and service-call experiences, and is also used for voice interactions in Tesla vehicles and Grok Bot. Billing is usage-based, with audio charged per minute and text input events billed separately. The API documentation includes setup instructions and examples for Python and JavaScript clients.
