OpenAI published an engineering account of GPT-Live, its third-generation voice system, describing six months of work to rebuild inference, context management and media transport for continuous speech. GPT-Live removes the separate turn detector from the audio path in favour of a full-duplex voice model that listens and speaks simultaneously, delegating deeper reasoning and tool calls asynchronously to frontier models such as GPT-5.5. The media frontend and inference logic were rewritten from Python asyncio into Go, with the new system's p95 frame-delivery matching the old p50, and seamless model-instance handoffs allow context compaction mid-call without audible interruption. OpenAI also introduced WARP (WebRTC Abridged Roundtrip Protocol), cutting media and data startup from six network round trips to one, plus an Instant Connect pre-negotiation scheme; WARP is being advanced through the IETF TSVWG working group and is already supported in libwebrtc and Pion.
