public final class ResponseFormatJsonSchemaSchema implements JsonSerializable<ResponseFormatJsonSchemaSchema> {

    /*
     * The schema for the response format, described as a JSON Schema object.
     * Learn how to build JSON schemas [here](https://json-schema.org/).
     */
    @Generated
    private Map<String, BinaryData> additionalProperties;

    // ...
}
