OpenAI's GPT-Live Adds Async Delegation: Voice Keeps Talking While GPT-5.5 Works in the Background
OpenAI launched GPT-Live on July 8, 2026, and Simon Willison (who had weeks of preview access) details its standout pattern: the full-duplex voice model delegates hard sub-tasks — web search, deeper reasoning, complex work — to GPT-5.5 running in the background while it keeps the conversation flowing, folding results back in when ready, and auto-upgrades its backing model as new frontier models ship. For builders: a clean reference architecture for responsive voice agents that stay conversational while offloading heavy reasoning asynchronously, rather than blocking on one slow call.
