获取给定输入的矢量表示，机器学习模型和算法可以轻松使用该表示。

Create embeddings

POST https://api.openai.com/v1/embeddings

创建表示输入文本的嵌入向量。

Request body

字段	类型	是否可选	说明
model	string	必须	要使用的模型的 ID。您可以使用 List models API 来查看所有可用模型。
input	string or array	必须	输入文本以获取嵌入，编码为字符串或标记数组。要在单个请求中获取多个输入的嵌入，请传递一个字符串数组或令牌数组数组。每个输入的长度不得超过 8192 个标记。
user	string	可选	代表您的最终用户的唯一标识符，可以帮助 OpenAI 监控和检测滥用行为。

import openai
openai.api_key = os.getenv("OPENAI_API_KEY")
openai.Embedding.create(
  model="text-embedding-ada-002",
  input="The food was delicious and the waiter..."
)

const { Configuration, OpenAIApi } = require("openai");
const configuration = new Configuration({
  apiKey: process.env.OPENAI_API_KEY,
