OpenAI's GPT-Realtime Debuts

29 August 2025

OpenAI has launched gpt-realtime, a new speech-to-speech model designed to enhance AI voice applications. This model aims to provide more natural and expressive voices for enterprise use, improving customer support, personal assistance, and education applications. Gpt-realtime is now generally available through the updated Realtime API.

Gpt-realtime improves upon previous models by directly processing audio, reducing latency and capturing subtle cues like pauses and laughter. It excels at following complex instructions, accurately calling tools, and seamlessly switching between languages. The model also introduces two new voices, Cedar and Marin.

OpenAI's gpt-realtime offers enhanced reasoning and more natural speech, enabling it to handle intricate, multi-step requests. This advancement simplifies complex interactions, potentially making AI interactions feel more human-like.
