 - GPT-4o real-time audio is designed to handle real-time, low-latency conversational interactions, making it a great fit for support agents, assistants, translators, and other use cases that need highly responsive back-and-forth with a user. For more information on how to use GPT-4o real-time audio, see the [GPT-4o real-time audio quickstart](../realtime-audio-quickstart.md) and [how to use GPT-4o audio](../how-to/realtime-audio.md).
 - GPT-4o audio completion is designed to generate audio from audio or text prompts, making it a great fit for generating audio books, audio content, and other use cases that require audio generation. The GPT-4o audio completions model introduces the audio modality into the existing `/chat/completions` API. For more information on how to use GPT-4o audio completions, see the [audio generation quickstart](../audio-completions-quickstart.md).

 To use GPT-4o audio, you need [an Azure OpenAI resource](../how-to/create-resource.md) in one of the [supported regions](#global-standard-model-availability).
 
 When your resource is created, you can [deploy](../how-to/create-resource.md#deploy-a-model) the GPT-4o audio model.
