class langchain_community.utilities.dalle_image_generator.DallEAPIWrapper

Bases: BaseModel

Wrapper for OpenAI’s DALL-E Image Generator.

https://platform.openai.com/docs/guides/images/generations?context=node

Usage instructions:

1. pip install openai

2. save your OPENAI_API_KEY in an environment variable

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.

param default_headers: Optional[Mapping[str, str]] = None

param default_query: Optional[Mapping[str, object]] = None

param http_client: Optional[Any] = None

Optional httpx.Client.

param max_retries: int = 2

Maximum number of retries to make when generating.

param model_kwargs: Dict[str, Any] [Optional]

param model_name: str = 'dall-e-2' (alias 'model')

param n: int = 1

Number of images to generate

param openai_api_base: Optional[str] = None (alias 'base_url')

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

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

Automatically inferred from env var OPENAI_API_KEY if not provided.

param openai_organization: Optional[str] = None (alias 'organization')

Automatically inferred from env var OPENAI_ORG_ID if not provided.

param openai_proxy: Optional[str] = None

param quality: Optional[str] = 'standard'

Quality of the image that will be generated

param request_timeout: Optional[Union[float, Tuple[float, float], Any]] = None (alias 'timeout')

param separator: str = '\n'

Separator to use when multiple URLs are returned.

param size: str = '1024x1024'

Size of image to generate

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

Parameters

• _fields_set (Optional[SetStr]) –

• values (Any) –

Return type

Model

copy(*, include: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, exclude: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, update: Optional[DictStrAny] = None, deep: bool = False) → Model

Duplicate a model, optionally choose which fields to include, exclude and change.

Parameters

• include (Optional[Union[AbstractSetIntStr, MappingIntStrAny]]) – fields to include in new model

• exclude (Optional[Union[AbstractSetIntStr, MappingIntStrAny]]) – fields to exclude from new model, as with values this takes precedence over include

• update (Optional[DictStrAny]) – values to change/add in the new model. Note: the data is not validated before creating the new model: you should trust this data

• deep (bool) – set to True to make a deep copy of the model

• self (Model) –

Returns

new model instance

Return type

Model

dict(*, include: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, exclude: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, by_alias: bool = False, skip_defaults: Optional[bool] = None, exclude_unset: bool = False, exclude_defaults: bool = False, exclude_none: bool = False) → DictStrAny

Generate a dictionary representation of the model, optionally specifying which fields to include or exclude.

Parameters

• include (Optional[Union[AbstractSetIntStr, MappingIntStrAny]]) –

• exclude (Optional[Union[AbstractSetIntStr, MappingIntStrAny]]) –

• by_alias (bool) –

• skip_defaults (Optional[bool]) –

• exclude_defaults (bool) –

• exclude_none (bool) –

Generate a JSON representation of the model, include and exclude arguments as per dict().

encoder is an optional function to supply as default to json.dumps(), other arguments as per json.dumps().
