OpenAI Unveils WebRTC Architecture for Low-Latency Voice to 900M Users
OpenAI has introduced a new WebRTC system that may help deliver low-latency voice to about 900 million weekly users. This design splits the work between a stateless relay at the network edge and a stateful transceiver in regional clusters, which seems to lower voice delay to under 400 ms for most users. Routing information is encoded in the ICE ufrag, allowing fast connection setup and possibly helping other large deployments with similar issues. Early results suggest this setup reduces costs and speeds up upgrades, while precautions are in place to limit security risks. The architecture appears to suggest a trend toward separating simple routing at the edge from more complex processing deeper in the network.
