About

GPT-4o Audio is OpenAI’s GPT-4o line for models that take and produce audio as well as text. It sits on GPT-4o (“o” for omni), OpenAI’s flagship trained end-to-end across text, vision, and audio so one network can hear tone and speakers and reply with speech, not only a separate speech-to-text then text then text-to-speech pipeline. In the API, the GPT-4o Audio preview models accept text and audio input and return text and audio output through Chat Completions.
