GPT Audio is OpenAI's latest flagship model capable of understanding and generating text and audio in real-time, designed for natural conversation and auditory tasks.
Coding and code review
Generate, debug, and review code across languages, reading whole files or repos in a single prompt.
Agentic and multi-step workflows
Reliable tool-calling and instruction-following suit agent loops that plan, call tools, and iterate.
Long-document analysis
Summarize and extract from contracts, papers, and reports without aggressive chunking.
Use cases
A voice interface for an existing text agent is a documented use case for this model family, where audio input and output can be added to a chat application to support spoken interaction. Live transcription is another documented fit, because the audio stack supports turning audio into text for streaming or bounded transcription workflows. Narration or generated speech is also supported through the audio system’s text-to-speech path, which is described as useful for producing spoken audio from text.
