OptionalbackgroundThe image(s) to edit. Must be a supported image file or an array of images.
For gpt-image-1, each image should be a png, webp, or jpg file less than
50MB. You can provide up to 16 images.
For dall-e-2, you can only provide one image, and it should be a square png
file less than 4MB.
Optionalinput_Control how much effort the model will exert to match the style and features,
especially facial features, of input images. This parameter is only supported
for gpt-image-1. Supports high and low. Defaults to low.
OptionalmaskAn additional image whose fully transparent areas (e.g. where alpha is zero)
indicate where image should be edited. If there are multiple images provided,
the mask will be applied on the first image. Must be a valid PNG file, less than
4MB, and have the same dimensions as image.
OptionalmodelThe model to use for image generation. Only dall-e-2 and gpt-image-1 are
supported. Defaults to dall-e-2 unless a parameter specific to gpt-image-1
is used.
OptionalnThe number of images to generate. Must be between 1 and 10.
Optionaloutput_The compression level (0-100%) for the generated images. This parameter is only
supported for gpt-image-1 with the webp or jpeg output formats, and
defaults to 100.
Optionaloutput_The format in which the generated images are returned. This parameter is only
supported for gpt-image-1. Must be one of png, jpeg, or webp. The
default value is png.
Optionalpartial_The number of partial images to generate. This parameter is used for streaming responses that return partial images. Value must be between 0 and 3. When set to 0, the response will be a single image sent in one streaming event.
Note that the final image may be sent before the full number of partial images are generated if the full image is generated more quickly.
A text description of the desired image(s). The maximum length is 1000
characters for dall-e-2, and 32000 characters for gpt-image-1.
OptionalqualityThe quality of the image that will be generated. high, medium and low are
only supported for gpt-image-1. dall-e-2 only supports standard quality.
Defaults to auto.
Optionalresponse_The format in which the generated images are returned. Must be one of url or
b64_json. URLs are only valid for 60 minutes after the image has been
generated. This parameter is only supported for dall-e-2, as gpt-image-1
will always return base64-encoded images.
OptionalsizeThe size of the generated images. Must be one of 1024x1024, 1536x1024
(landscape), 1024x1536 (portrait), or auto (default value) for
gpt-image-1, and one of 256x256, 512x512, or 1024x1024 for dall-e-2.
OptionalstreamEdit the image in streaming mode. Defaults to false. See the
Image generation guide
for more information.
OptionaluserA unique identifier representing your end-user, which can help OpenAI to monitor and detect abuse. Learn more.
Allows to set transparency for the background of the generated image(s). This parameter is only supported for
gpt-image-1. Must be one oftransparent,opaqueorauto(default value). Whenautois used, the model will automatically determine the best background for the image.If
transparent, the output format needs to support transparency, so it should be set to eitherpng(default value) orwebp.
