DALLEImageGenerator

Generates images using OpenAI's DALL-E model.

Basic Information

• Type: haystack_integrations.generators.openai_dalle.DALLEImageGenerator

Inputs

Parameter	Type	Default	Description
prompt	str		The prompt to generate the image.
size	Optional[Literal['256x256', '512x512', '1024x1024', '1792x1024', '1024x1792']]	None	If provided, overrides the size provided during initialization.
quality	Optional[Literal['standard', 'hd']]	None	If provided, overrides the quality provided during initialization.
response_format	Optional[Optional[Literal['url', 'b64_json']]]	None	If provided, overrides the response format provided during initialization.

Outputs

Parameter	Type	Default	Description
images	List[str]		A dictionary containing the generated list of images and the revised prompt. Depending on the response_format parameter, the list of images can be URLs or base64 encoded JSON strings. The revised prompt is the prompt that was used to generate the image, if there was any revision to the prompt made by OpenAI.
revised_prompt	str		A dictionary containing the generated list of images and the revised prompt. Depending on the response_format parameter, the list of images can be URLs or base64 encoded JSON strings. The revised prompt is the prompt that was used to generate the image, if there was any revision to the prompt made by OpenAI.

Parameters

Init Parameters

These are the parameters you can configure in Pipeline Builder:

Parameter	Type	Default	Description
model	str	dall-e-3	The model to use for image generation. Can be "dall-e-2" or "dall-e-3".
quality	Literal['standard', 'hd']	standard	The quality of the generated image. Can be "standard" or "hd".
size	Literal['256x256', '512x512', '1024x1024', '1792x1024', '1024x1792']	1024x1024	The size of the generated images. Must be one of 256x256, 512x512, or 1024x1024 for dall-e-2. Must be one of 1024x1024, 1792x1024, or 1024x1792 for dall-e-3 models.
response_format	Literal['url', 'b64_json']	url	The format of the response. Can be "url" or "b64_json".
api_key	Secret	Secret.from_env_var('OPENAI_API_KEY')	The OpenAI API key to connect to OpenAI.
api_base_url	Optional[str]	None	An optional base URL.
organization	Optional[str]	None	The Organization ID, defaults to None.
timeout	Optional[float]	None	Timeout for OpenAI Client calls. If not set, it is inferred from the OPENAI_TIMEOUT environment variable or set to 30.
max_retries	Optional[int]	None	Maximum retries to establish contact with OpenAI if it returns an internal error. If not set, it is inferred from the OPENAI_MAX_RETRIES environment variable or set to 5.
http_client_kwargs	Optional[Dict[str, Any]]	None	A dictionary of keyword arguments to configure a custom httpx.Clientor httpx.AsyncClient. For more information, see the HTTPX documentation.

Run Method Parameters

These are the parameters you can configure for the component's run() method. This means you can pass these parameters at query time through the API, in Playground, or when running a job. For details, see Modify Pipeline Parameters at Query Time.

Parameter	Type	Default	Description
prompt	str		The prompt to generate the image.
size	Optional[Literal['256x256', '512x512', '1024x1024', '1792x1024', '1024x1792']]	None	If provided, overrides the size provided during initialization.
quality	Optional[Literal['standard', 'hd']]	None	If provided, overrides the quality provided during initialization.
response_format	Optional[Optional[Literal['url', 'b64_json']]]	None	If provided, overrides the response format provided during initialization.
