To use, you should have the ``openai`` python package installed, and the environment variable ``OPENAI_API_KEY`` set with your API key or pass it as a named parameter to the constructor. Example: .. code-block:: python from langchain_community.embeddings import OpenAIEmbeddings openai = OpenAIEmbeddings(openai_api_key="my-api-key") In order to use the library with Microsoft Azure endpoints, you need to set the OPENAI_API_TYPE, OPENAI_API_BASE, OPENAI_API_KEY and OPENAI_API_VERSION. The OPENAI_API_TYPE must be set to 'azure' and the others correspond to the properties of your endpoint. In addition, the deployment name must be passed as the model parameter. Example: .. code-block:: python import os os.environ["OPENAI_API_TYPE"] = "azure" os.environ["OPENAI_API_BASE"] = "https://Build extra kwargs from additional params that were passed in.rzFound z supplied twice.z WARNING! z/ is not default parameter. zJ was transferred to model_kwargs.
