Zero Runtime architecture: users connect through integrations to the fully managed real-time voice pipeline (denoise, VAD, STT, turn detection, LLM/realtime model, TTS), driven by your agent code in the Python SDK.
Zero Runtime lets you build real-time voice AI agents in Python. You write the agent code; we run the entire voice infrastructure including speech-to-text, LLM processing, text-to-speech, turn detection, noise cancellation, scaling, and GPUs. Your code runs in your process, while all real-time voice handling runs on ours.
Think serverless for voice AI: you build the agent, we run the runtime.
