接口说明

DeepSeek模型API HTTPS地址：

https://openapi.youdao.com/llmgateway/api/v1/chat/completions

协议须知

调用方在集成大模型翻译API时，请遵循以下规则。

规则 描述
传输方式 HTTPS
请求方式 POST
请求格式 application/json

接口调用参数

调用API需要向接口发送以下字段来访问服务。

  • Headers
参数名称 参数值 是否必须 示例 备注
Content-Type application/json 是 application/json
Authorization Bearer ${api_key} 是 在智云控制台申请 token鉴权

  • Body

    名称 类型 是否必须 默认值 备注 其他信息
    model string 必须 模型名称
    messages object [] 必须 消息列表 [ { "role": "system", "content": "You are a helpful assistant." }, { "role": "user", "content": "How's the weather in Hangzhou?" }, { "role": "assistant", "content": "", "tool_calls": [ { "id": "chatcmpl-tool-f6c2f72b91284f31b51988456cd9e8f0", "type": "function", "function": { "name": "get_weather", "arguments": "{\"location\":\"Hangzhou\"}" } } ] }, { "role": "tool", "tool_call_id": "chatcmpl-tool-f6c2f72b91284f31b51988456cd9e8f0", "content": "24℃" }, { "role": "assistant", "content": "The weather in Hangzhou is currently 24°C." } ]
    stream boolean 非必须 是否流式返回：默认值 false
    stream_options object 非必须 流式响应时的配置 备注: 流式响应时的配置
    max_tokens integer 非必须 模型的最大tokens数量：默认值 4096，最大16k
    stop string [] 非必须 模型遇到 stop 字段所指定的字符串时将停止继续生成，这个词语本身不会输出。最多支持 4 个字符串。 类型: string 或 string []
    presence_penalty number 非必须 存在惩罚系数。如果值为正，会根据新 token 到目前为止是否出现在文本中对其进行惩罚，从而增加模型谈论新主题的可能性。取值范围为 [-2.0, 2.0]。
    frequency_penalty number 非必须 频率惩罚系数。如果值为正，会根据新 token 在文本中的出现频率对其进行惩罚，从而降低模型逐字重复的可能性。取值范围为 [-2.0, 2.0]。
    temperature number 非必须 采样温度。控制了生成文本时对每个候选词的概率分布进行平滑的程度。取值范围为 [0, 2]。当取值为 0 时模型仅考虑对数概率最大的一个 token。较高的值（如 0.8）会使输出更加随机，而较低的值（如 0.2）会使输出更加集中确定。通常建议仅调整 temperature 或 top_p 其中之一，不建议两者都修改。
    top_p number 非必须 核采样概率阈值。模型会考虑概率质量在 top_p 内的 token 结果。取值范围为 [0, 1]。当取值为 0 时模型仅考虑对数概率最大的一个 token。如 0.1 意味着只考虑概率质量最高的前 10% 的 token，取值越大生成的随机性越高，取值越低生成的确定性越高。通常建议仅调整 temperature 或 top_p 其中之一，不建议两者都修改。
    logit_bias object 非必须 调整指定 token 在模型输出内容中出现的概率，使模型生成的内容更加符合特定的偏好。logit_bias 字段接受一个 map 值，其中每个键为词表中的 token ID（使用 tokenization 接口获取），每个值为该 token 的偏差值，取值范围为 [-100, 100]。-1 会减少选择的可能性，1 会增加选择的可能性；-100 会完全禁止选择该 token，100 会导致仅可选择该 token。该参数的实际效果可能因模型而异。 备注: 调整指定 token 在模型输出内容中出现的概率，使模型生成的内容更加符合特定的偏好。logit_bias 字段接受一个 map 值，其中每个键为词表中的 token ID（使用 tokenization 接口获取），每个值为该 token 的偏差值，取值范围为 [-100, 100]。 -1 会减少选择的可能性，1 会增加选择的可能性；-100 会完全禁止选择该 token，100 会导致仅可选择该 token。该参数的实际效果可能因模型而异。
    tools object [] 非必须 待调用工具的列表，模型返回信息中可包含。当您需要让模型返回待调用工具时，需要配置该结构体。 [{ "type": "function", "function": { "name": "get_weather", "description": "Get weather of an location, the user shoud supply a location first", "parameters": { "type": "object", "properties": { "location": { "type": "string", "description": "The city and state, e.g. San Francisco, CA" } }, "required": ["location"] } } }]

模型选项

模型 版本 最大上下文长度 最大输入长度(token) 最大输出长度 最大思考内容长度 刊例价(元/1M token)
DeepSeek-R1 实时 64k 48k 16k 16k 输入：4元 输出：16元
DeepSeek-V3 实时 64k 48k 16k - 输入：2元 输出：8元

输出结果

  • 如果stream=false，非流式返回，返回结果为json
  • 如果stream=true，流式返回，输出结果为响应式流。
