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

Vision Agents is a versatile open-source Python framework designed for developing low-latency voice and video AI agents utilizing any model. This framework empowers developers to integrate large language models, speech recognition, and vision models from over 25 different providers, enabling the creation of real-time agents for applications such as telehealth, voice assistance, live coaching, video analysis, interactive avatars, security surveillance, sports commentary, and a variety of other multimodal uses. Its architecture is tailored to facilitate the development of agents capable of listening, speaking, seeing, processing media, accessing tools, and providing instant responses, all while operating on Stream's expansive global edge network, which ensures latency below 500ms. With just a minimal Python setup, developers can quickly create their first agent by leveraging platforms like Gemini Realtime, OpenAI, Deepgram, ElevenLabs, Stream, or other compatible providers. Furthermore, Vision Agents accommodates both real-time speech-to-speech models and tailored speech-to-text, language processing, and text-to-speech pipelines, allowing teams to either rapidly deploy a functional voice agent or exercise complete control over the components involved in speech recognition, language reasoning, and text-to-speech functionalities. Overall, this framework not only simplifies the process of building sophisticated AI agents but also enhances flexibility and performance across diverse applications.
