GPT-Realtime-2
Also known as: GPT-Realtime-2 / gpt-realtime-1.5 / GPT Realtime API
OpenAI's real-time voice AI model delivering ultra-low-latency full-duplex speech interaction — designed for voice agents and live translation use cases.
Overview
GPT-Realtime-2 succeeds gpt-realtime-1.5 and packages a reasoning voice agent, live translation, and streaming Whisper into a unified stack. See OpenAI GPT-Realtime-2 explainer for details.
Use cases
Used in contact-centre automation, real-time meeting interpretation, and voice-first UIs where text-only LLMs struggle with latency.
