OpenAI launched three new real-time audio API models in May 2026, marking the Realtime API's exit from beta into general availability. GPT-Realtime-2 is the flagship - OpenAI's first voice model built on GPT-5-class reasoning that processes audio in a continuous stream without the transcription-to-LLM-to-synthesis latency gap. GPT-Realtime-Translate adds 70+ input / 13 output language live translation. GPT-Realtime-Whisper adds streaming live transcription. Together they move real-time audio from call-and-response toward voice interfaces that can listen, reason, translate, and take action as conversations unfold.
