Create image edit

client.Images.Edit(ctx, body) (*ImagesResponse, error)

POST/images/edits

Creates an edited or extended image given one or more source images and a prompt. This endpoint supports GPT Image models (gpt-image-1.5, gpt-image-1, and gpt-image-1-mini) and dall-e-2.

ParametersExpand Collapse

body ImageEditParams

Image param.Field[ImageEditParamsImageUnion]

The image(s) to edit. Must be a supported image file or an array of images.

For the GPT image models (gpt-image-1, gpt-image-1-mini, and gpt-image-1.5), 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.

Reader

[]Reader

Prompt param.Field[string]

A text description of the desired image(s). The maximum length is 1000 characters for dall-e-2, and 32000 characters for the GPT image models.

Background param.Field[ImageEditParamsBackground]optional

Allows to set transparency for the background of the generated image(s). This parameter is only supported for the GPT image models. Must be one of transparent, opaque or auto (default value). When auto 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 either png (default value) or webp.

const ImageEditParamsBackgroundTransparent ImageEditParamsBackground = "transparent"

const ImageEditParamsBackgroundOpaque ImageEditParamsBackground = "opaque"

const ImageEditParamsBackgroundAuto ImageEditParamsBackground = "auto"

InputFidelity param.Field[ImageEditParamsInputFidelity]optional

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 and gpt-image-1.5 and later models, unsupported for gpt-image-1-mini. Supports high and low. Defaults to low.

const ImageEditParamsInputFidelityHigh ImageEditParamsInputFidelity = "high"

const ImageEditParamsInputFidelityLow ImageEditParamsInputFidelity = "low"

Mask param.Field[Reader]optional

An 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.

Model param.Field[ImageModel]optional

The model to use for image generation. Only dall-e-2 and the GPT image models are supported. Defaults to dall-e-2 unless a parameter specific to the GPT image models is used.

string

type ImageModel string

Accepts one of the following:

const ImageModelGPTImage1_5 ImageModel = "gpt-image-1.5"

const ImageModelDallE2 ImageModel = "dall-e-2"

const ImageModelDallE3 ImageModel = "dall-e-3"

const ImageModelGPTImage1 ImageModel = "gpt-image-1"

const ImageModelGPTImage1Mini ImageModel = "gpt-image-1-mini"

N param.Field[int64]optional

The number of images to generate. Must be between 1 and 10.

minimum1

maximum10

OutputCompression param.Field[int64]optional

The compression level (0-100%) for the generated images. This parameter is only supported for the GPT image models with the webp or jpeg output formats, and defaults to 100.

OutputFormat param.Field[ImageEditParamsOutputFormat]optional

The format in which the generated images are returned. This parameter is only supported for the GPT image models. Must be one of png, jpeg, or webp. The default value is png.

const ImageEditParamsOutputFormatPNG ImageEditParamsOutputFormat = "png"

const ImageEditParamsOutputFormatJPEG ImageEditParamsOutputFormat = "jpeg"

const ImageEditParamsOutputFormatWebP ImageEditParamsOutputFormat = "webp"

PartialImages param.Field[int64]optional

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.

maximum3

minimum0

Quality param.Field[ImageEditParamsQuality]optional

The quality of the image that will be generated. high, medium and low are only supported for the GPT image models. dall-e-2 only supports standard quality. Defaults to auto.

const ImageEditParamsQualityStandard ImageEditParamsQuality = "standard"

const ImageEditParamsQualityLow ImageEditParamsQuality = "low"

const ImageEditParamsQualityMedium ImageEditParamsQuality = "medium"

const ImageEditParamsQualityHigh ImageEditParamsQuality = "high"

const ImageEditParamsQualityAuto ImageEditParamsQuality = "auto"

ResponseFormat param.Field[ImageEditParamsResponseFormat]optional

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 the GPT image models always return base64-encoded images.

const ImageEditParamsResponseFormatURL ImageEditParamsResponseFormat = "url"

const ImageEditParamsResponseFormatB64JSON ImageEditParamsResponseFormat = "b64_json"

Size param.Field[ImageEditParamsSize]optional

The size of the generated images. Must be one of 1024x1024, 1536x1024 (landscape), 1024x1536 (portrait), or auto (default value) for the GPT image models, and one of 256x256, 512x512, or 1024x1024 for dall-e-2.

const ImageEditParamsSize256x256 ImageEditParamsSize = "256x256"

const ImageEditParamsSize512x512 ImageEditParamsSize = "512x512"

const ImageEditParamsSize1024x1024 ImageEditParamsSize = "1024x1024"
