Pythia-6.9B由EleutherAI研发并开源，在Pile数据集上训练的6.9B参数transformer语言模型。本文介绍了相关API。

创建completion

调用本接口，发起一次文本续写请求。

请求示例（流式）

• bash
• Python

# 步骤一，获取access_token，替换下列示例中的应用API Key与应用Secret Key
curl 'https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id=[应用API Key]&client_secret=[应用Secret Key]'

# 步骤二，调用本文API，使用步骤一获取的access_token，替换下列示例中的“调用接口获取的access_token”；替换示例中的申请发布时填写的API名称
curl -X POST 'https://aip.baidubce.com/rpc/2.0/ai_custom/v1/wenxinworkshop/completions/[申请发布时填写的API名称]?access_token=[步骤一调用接口获取的access_token]' -d '{
  "prompt":"Introduce the city Beijing",
  "stream": true
}'

错误码

如果请求错误，服务器返回的JSON文本包含以下参数。

名称	描述
error_code	错误码
error_msg	错误描述信息，帮助理解和解决发生的错误

例如Access Token失效返回以下内容，需要重新获取新的Access Token再次请求。

{
  "error_code": 110,
  "error_msg": "Access token invalid or no longer valid"
}

说明： （1）较高的数值会使输出更加随机，而较低的数值会使其更加集中和确定 （2）范围 (0, 1.0]，不能为0 （3）建议该参数和top_p只设置1个

{
  "prompt": "string",
  "stream": true,
  "temperature\t": 0,
  "top_k\t": 0,
  "top_p\t": 0,
  "penalty_score": 0,
  "stop\t": [
    "string"
  ],
  "user_id": "string"
}
