        Creates an embedding vector representing the input text.

        Args:
          input: 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
              all embedding models), cannot be an empty string, and any array must be 2048
              dimensions or less.
              [Example Python code](https://cookbook.openai.com/examples/how_to_count_tokens_with_tiktoken)
              for counting tokens. In addition to the per-input token limit, all embedding
              models enforce a maximum of 300,000 tokens summed across all inputs in a single
              request.

          model: ID of the model to use. You can use the
              [List models](https://platform.openai.com/docs/api-reference/models/list) API to
              see all of your available models, or see our
              [Model overview](https://platform.openai.com/docs/models) for descriptions of
              them.

          dimensions: The number of dimensions the resulting output embeddings should have. Only
              supported in `text-embedding-3` and later models.

          encoding_format: The format to return the embeddings in. Can be either `float` or
              [`base64`](https://pypi.org/project/pybase64/).

          user: A unique identifier representing your end-user, which can help OpenAI to monitor
              and detect abuse.
