首先需要先申请文心千帆大模型申请地址文心一言 (baidu.com)点击加入体验等通过审核之后就可以进入文心千帆大模型后台进行应用管理了。
在百度智能云首页即可看到文心千帆大模型平台
然后进入后台管理之后点击应用接入创建应用即可
创建完应应用之后便可以调用文心一言的http开发接口进行交互了。
接口对接
接口文档
首先要看一下接口文档API调用指南 - 文心千帆WENXINWORKSHOP | 百度智能云文档 (baidu.com)
这里我用的是ERNIE-Bot-turbo API主要是由于它响应更快。
下面介绍一下具体接入的代码

以上就是通过文心一言的OpenAPI与大模型交互的整体逻辑等代码功能再做完善之后改代码会以SDK的方式开源到Gitee欢迎一起探讨。
