GPT-4o Mini Realtime

by OpenAI

GPT-4o Mini Realtime is the smaller, faster member of OpenAI's realtime voice family, built for interactive, low-latency conversations. It is a native speech-to-speech model, taking audio in and producing spoken responses directly rather than chaining separate transcription and synthesis steps. It supports function calling, so voice agents can invoke external APIs mid-conversation, and voice activity detection helps it respond promptly without processing silence. Its smaller size keeps cost and latency low, which fits customer service bots, voice assistants, and hands-free applications where responsiveness matters more than maximum reasoning depth.
