Developer notes on the Realtime API

OpenAI has recently launched its gpt-realtime speech-to-speech model alongside the general availability of the Realtime API, introducing numerous enhancements in model quality, reliability, and developer ergonomics. The release includes new API features and improvements designed to better support production voice applications, such as conversation idle timeouts, asynchronous function calling, and a long context handling capability. The Realtime API has been updated to a GA interface, which supports a range of features unavailable in the beta interface, urging clients to migrate for continued access and functionality. Notable changes include the removal of the temperature parameter in the GA interface, improved handling of long sessions, automatic truncation of messages when token limits are reached, and support for EU data residency. Developers can now leverage hosted prompts and sideband connections for more flexible session management and integration, ensuring secure and client-agnostic business logic. These updates aim to enhance the user experience and provide developers with robust tools to create sophisticated voice applications.
