About
GPT Realtime Whisper is OpenAI's streaming speech-to-text model, released May 7, 2026. It transcribes spoken audio live as a speaker talks rather than waiting for utterance completion, making it suitable for live captions, meeting notes, classroom transcripts, and real-time agent pipelines. The model is exposed through /v1/realtime/transcription_sessions and is priced per minute at $0.017 rather than per token.
GPT Realtime Whisper is a proprietary model in the GPT Realtime 2 family. The structured metadata tracks audio. This page tracks provider routes through OpenAI API. No headline benchmark score is tracked for GPT Realtime Whisper yet.
