To use, you should have the environment variable AZURE_OPENAI_API_KEY set with your API key or pass it as a named parameter to the constructor.

Example

from langchain_openai import AzureOpenAIEmbeddings

openai = AzureOpenAIEmbeddings(model="text-embedding-3-large")

Create a new model by parsing and validating input data from keyword arguments.

Raises ValidationError if the input data cannot be parsed to form a valid model.

Base URL path for API requests, leave blank if not using a proxy or service emulator.

param openai_api_key: Optional[SecretStr] = None (alias 'api_key')¶

Automatically inferred from env var AZURE_OPENAI_API_KEY if not provided.

Constraints

  • type = string

  • writeOnly = True

  • format = password

param show_progress_bar: bool = False¶

Whether to show a progress bar when embedding.

param skip_empty: bool = False¶

Whether to skip empty strings when embedding or raise an error. Defaults to not skipping.

param tiktoken_enabled: bool = True¶

Set this to False for non-OpenAI implementations of the embeddings API, e.g. the –extensions openai extension for text-generation-webui

param tiktoken_model_name: Optional[str] = None¶

The model name to pass to tiktoken when using this class. Tiktoken is used to count the number of tokens in documents to constrain them to be under a certain limit. By default, when set to None, this will be the same as the embedding model name. However, there are some cases where you may want to use this Embedding class with a model name not supported by tiktoken. This can include when using Azure embeddings or when using one of the many model providers that expose an OpenAI-like API but with different models. In those cases, in order to avoid erroring when tiktoken is called, you can specify a model name to use here.

param validate_base_url: bool = True¶
async aembed_documents(texts: List[str], chunk_size: Optional[int] = 0) → List[List[float]]¶

Call out to OpenAI’s embedding endpoint async for embedding search docs.

classmethod construct(_fields_set: Optional[SetStr] = None, **values: Any) → Model¶

Creates a new model setting __dict__ and __fields_set__ from trusted or pre-validated data. Default values are respected, but no other validation is performed. Behaves as if Config.extra = ‘allow’ was set since it adds all passed values
