Open AI Cookbook | Realtime Prompting Guide
Today, we’re releasing gpt-realtime — our most capable speech-to-speech model yet in the API and announcing the general availability of the Realtime API.
Speech-to-speech systems are essential for enabling voice as a core AI interface. The new release enhances robustness and usability, giving enterprises the confidence to deploy mission-critical voice agents at scale.
The new gpt-realtime model delivers stronger instruction following, more reliable tool calling, noticeably better voice quality, and an overall smoother feel. These gains make it practical to move from chained approaches to true realtime experiences, cutting latency and producing responses that sound more natural and expressive.
Realtime model benefits from different prompting techniques that wouldn’t directly apply to text based models. This prompting guide starts with a suggested prompt skeleton, then walks through each part with practical tips, small patterns you can copy, and examples you can adapt to your use case.
Happy learning!
