GPT‑Live‑1 in the API

OpenAI is launching GPT-Live-1 in its API, providing developers with a natural voice model for voice-enabled applications and business workflows. This model, first seen in ChatGPT, can listen and speak simultaneously, and delegate reasoning to paired models and tools. GPT-Live-1 improves Full Duplex Bench performance by 30 percentage points over GPT-Realtime-2.1 and ranks #1 on Tau3 when paired with GPT-6 Astra. OpenAI Presence also utilizes GPT-Live-1 for real-time voice interactions, enabling AI agents for enterprise use.
