# 插件的开发过程<a name="ZH-CN_TOPIC_0000001077767652"></a>

AI引擎框架规定了一套算法插件接入规范，各插件需实现规定接口以实现获取插件版本信息、算法推理类型、同步执行算法、异步执行算法、加载算法插件、卸载算法插件、设置算法配置信息、获取指定算法配置信息等功能。（同步算法实现SyncProcess接口，异步算法实现AsyncProcess接口）。

1）算法插件类IPlugin接口设计如下[表1](#table1329717488505)所示。

Request、Response是ai引擎服务端与算法插件进行通信的对象。Request封装了调用方的请求、输入数据等，而插件主要通过Response将运算之后的结果返回给AI引擎服务端。
