CryptoWorld News reports that the OpenAI engineering team has publicly revealed the underlying WebRTC architecture supporting real-time voice AI products such as ChatGPT voice and real-time API.
The core solution is to split the traditional WebRTC media routing and protocol termination into two layers: a stateless relay responsible only for UDP packet forwarding, and a stateful transceiver responsible for complete ICE (Interactive Connectivity Establishment), DTLS (Datagram Transport Layer Security) handshake, and encryption/decryption.
This design addresses the classic challenges of WebRTC on Kubernetes, reducing the exposed public UDP surface to a fixed small number of addresses and ports after splitting, allowing the relay to scale horizontally.
The article also reveals that WebRTC protocol original architect Justin Uberti and the creator of the open-source WebRTC library Pion, Sean Dubois, have both joined OpenAI to participate in the integration of real-time AI and WebRTC.
