Describes how OpenAI used LiveKit's open source stack to build the production infrastructure for ChatGPT’s Advanced Voice Mode, focusing on architecture choices for scale, reliability, and low latency. Covers technical and business reasons for choosing open source, concrete scaling challenges and metrics from millions of calls, lessons learned and trade-offs, plus how others can reuse the same stack for their voice AI projects.
