HOW OPENAI DELIVERS LOW-LATENCY VOICE AI AT SCALE

Summary from the TLDR Dev newsletter

OpenAI rearchitected its WebRTC stack for low-latency voice AI delivery to over 900 million users by adopting a "split relay plus transceiver" architecture to address Kubernetes integration and port management challenges. This design uses a stateless relay for efficient packet routing and a stateful transceiver to manage WebRTC sessions.
