Audio en Chat Completions

Si ya tienes una aplicación de texto que usa un LLM a través del punto de acceso de Chat Completions, quizá quieras agregar funciones de audio. Por ejemplo, si tu aplicación de chat acepta texto como entrada, puedes agregar entrada y salida de audio. Para hacerlo, incluye audio en el arreglo modalities y usa un modelo de audio, como gpt-audio-1.5.

Actualmente, la documentación de la API de Responses describe las entradas de texto e imágenes con salidas de texto. Para implementar este tipo de chat con audio, usa Chat Completions con un modelo compatible con audio.
