Las estadísticas de salida se devuelven en el campo de nivel superior usage, al mismo nivel que output. Léase como response.usage["image_count"], donde image_count es el número total de imágenes generadas por la tarea. El objeto output no contiene estadísticas: response.output.usage se devuelve como {} y no contiene image_count.
