Optional
backgroundThe 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.
Optional
input_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
.
Optional
maskAn 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
.
Optional
modelThe 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.
Optional
nThe number of images to generate. Must be between 1 and 10.
Optional
output_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.
Optional
output_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
.
Optional
partial_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
.
Optional
qualityThe 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
.
Optional
response_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.
Optional
sizeThe 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
.
Edit the image in streaming mode. Defaults to false
. See the
Image generation guide
for more information.
Optional
userA 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
,opaque
orauto
(default value). Whenauto
is 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
.
