TEN (Transformative Extensions Network) is an open-source framework that enables developers to create real-time multimodal AI agents capable of interacting through voice, video, text, images, and data streams with extremely low latency. The framework encompasses a comprehensive ecosystem, including TEN Turn Detection, TEN Agent, and TMAN Designer, which collectively allow developers to quickly construct agents that exhibit human-like responsiveness and can perceive, articulate, and engage with users. It supports various programming languages such as Python, C++, and Go, providing versatile deployment options across both edge and cloud infrastructures. By leveraging features like graph-based workflow design, a user-friendly drag-and-drop interface via TMAN Designer, and reusable components such as real-time avatars, retrieval-augmented generation (RAG), and image synthesis, TEN facilitates the development of highly adaptable and scalable agents with minimal coding effort. This innovative framework opens up new possibilities for creating advanced AI interactions across diverse applications and industries.
