input

string

必需

Input text to embed, encoded as a string or array of tokens. To embed multiple inputs in a single request, pass an array of strings or array of token arrays. The input must not exceed the max input tokens for the model (8192 tokens for text-embedding-ada-002), cannot be an empty string, and any array must be 2048 dimensions or less. Example Python code for counting tokens.

model

string

必需

ID of the model to use. You can use the List models API to see all of your available models, or see our Model overview for descriptions of them.

encoding_format

string

必需

The format to return the embeddings in. Can be either float or base64.

{
  "input": "The food was delicious and the waiter...",
  "model": "text-embedding-ada-002",
  "encoding_format": "float"
}
