FastRTC: Python real-time communication library with WebRTC, Gradio UI, and LLM/TTS/STT integrations

AI Impact Summary

FastRTC introduces a Python-native real-time communication library that consolidates live audio/video streaming, voice activity detection, and a Gradio-based UI to streamline experimentation. It supports WebRTC/WebSocket transport, easy deployment into a FastAPI app, and built-in TTS/STT with optional LLM integration (e.g., SambaNova/OpenAI client), enabling end-to-end real-time conversational workloads on CPU. For teams, this accelerates the development and deployment of voice-enabled features, but adds dependencies on external services (OpenAI, Gemini, SambaNova) and FastPhone quotas that can influence cost and scalability at production scale.
