Summary

OpenAI has launched GPT Real-time Whisper, a new streaming endpoint for its Whisper audio transcription model, designed for low-latency speech-to-text. This model is part of a recent suite of real-time endpoints, including GPT Real-time 2 (based on GPT 5.5) and GPT Real-time Translate. GPT Real-time Whisper offers multilingual transcription, capable of detecting and transcribing various languages in real time, as demonstrated with English, Hindi, and Tamil audio. Unlike other OpenAI models, it is priced per minute at approximately 1.7 to 2 cents, making it cost-effective for high-volume audio transcription. While OpenAI did not specify the underlying Whisper model version (e.g., tiny, small, large), it is optimized for streaming and low-latency use cases, making live speech usable in business workflows for meetings, broadcasts, and interviews.

Key takeaway

For AI Engineers or developers building applications requiring immediate speech-to-text, GPT Real-time Whisper offers a robust, cost-effective solution. You should consider integrating this streaming API for use cases like live meeting transcription, real-time captioning, or processing multilingual audio streams, leveraging its low latency and per-minute pricing model to optimize operational costs and user experience. Explore the provided GitHub repository to quickly set up and test its capabilities with your OpenAI API key.
