开放平台地址DeepSeek
登录deepseek开放平台创建API keys注意创建的时候复制key要不然找不到了 新账号有10元的体验额度不足可以充值10元体验额度的有效期为1个月 v3和R1的收费标准
1. deepseek-chat 模型优惠期至北京时间 2025 年 2 月 8 日 24:00期间 API 调用享历史价格优惠结束后将按每百万输入 tokens 2 元每百万输出 tokens 8 元计费。 2. deepseek-reasoner 模型上线即按每百万输入 tokens 4 元每百万输出 tokens 16 元计费。 二、获取开放API文档
接口地址首次调用 API | DeepSeek API Docs
进入接口文档提供了对话、补全、模型等接口我们找一个【对话补全】接口给了一个上下文让他补充说话 三、JAVA调用API文档
使用java调用API跟其他接口没什么区别方便上手注意下入参和返回参数就可以采用json格式。
-----对话上下文 { content: 欢迎加入虚拟电厂, role: system , name: muyunfei }, { content: 你好虚拟电厂与deepseek结合的方向说一下吧, role: user , name: 路人甲}
组装请求参数
{messages: [{content: 欢迎加入虚拟电厂,role: system,name: muyunfei}, {content: 你好虚拟电厂与deepseek结合的方向说一下吧,role: user,name: 路人甲}],model: deepseek-chat,frequency_penalty: 0,max_tokens: 2048,presence_penalty: 0,response_format: {type: text},stop: null,stream: false,stream_options: null,temperature: 1,top_p: 1,tools: null,tool_choice: none,logprobs: false,top_logprobs: null
}
返回数据参数格式
{id: 2fe86f3b-6e3b-4e65-b35a-1127c14c8739,object: chat.completion,created: 1738810567,model: deepseek-chat,choices: [{index: 0,message: {role: assistant,content: Hello!
