Learn how to control the quality and speed of image generation.
AI Background API provides you with three ways to create a background for your product:
Template-free approach
Template-based approach
Solid color background with product shadow only
Template-free approach
In the template-free approach, only text prompts are used for background generation. You can either generate prompts automatically with Autoprompt AI or write them manually for more control.
Template-free models
The template-free approach supports several background generation models. Available models are listed below:
v1
A stable, production-ready model optimized for product photography. Provides consistent results with fast processing times. Requires specific prompt formatting for best results. See Tips for more info.
v2
Advanced model with improved photorealism. Processes natural language prompts more effectively and works with diverse subjects (products, people, etc.). Slightly slower processing time due to enhanced quality algorithms.
v1 model is used by default.
We recommend starting with the v2 model as it is a flagship model.
Template-free v2 model options
v2 model supports the following options:
Prompt
The AI Background API accepts text prompts to define the background. Prompts can be generated automatically using Autoprompt AI or provided manually.
Autoprompt AI: Automatic prompt generation
Autoprompt AI analyzes the input product image and generates a text prompt tailored to create a contextually relevant background. This is useful for automating background generation, especially with large batches of images.
How to use it: Set the generate parameter to true within the prompt object in the scene section of your API request.
{
"scene": {
"model": "v2",
"prompt": {
"generate": true
}
}
}You can influence Autoprompt AI by providing guidelines. Guidelines can be specific keywords (e.g., "seaside, sunset, ocean") or more abstract concepts (e.g., "summer vibes," "pink monochromatic environment," "real life setting").
{
"scene": {
"model": "v2",
"prompt": {
"generate": true,
"guidelines": "seaside, sunset, ocean, beach, sand, waves"
}
}
}Custom prompts: Manual control
For even more precise control over the background, you can provide your own prompt. Custom prompts must be between 3 and 2048 characters.
Example:
{
"scene": {
"model": "v2",
"prompt": "Professional photo of a product. The background features a serene spa environment with natural wooden textures, soft white towels, and smooth pebbles. Lavender plants add to the calming ambiance. The lighting is soft and natural, coming from the left, creating a tranquil and inviting atmosphere perfect for wellness and relaxation. The setting exudes a sense of luxury and care, aligning with the product's high-end aesthetic."
}
}Negative prompt
The negative prompt parameter specifies elements to exclude from the generated background. The model will avoid including content matching this text. The negative_prompt must be between 3 and 2048 characters.
{
"scene": {
"model": "v2",
"prompt": "Professional photo of a product. The background features a serene spa environment with natural wooden textures, soft white towels, and smooth pebbles. Lavender plants add to the calming ambiance. The lighting is soft and natural, coming from the left, creating a tranquil and inviting atmosphere perfect for wellness and relaxation. The setting exudes a sense of luxury and care, aligning with the product's high-end aesthetic.",
"negative_prompt": "pixelated, low quality"
}
}Aspect ratio
By default, the aspect ratio is 1:1 with dimensions of 1024x1024px. But you can change it to any of the following values, listed from wider to taller:
12:5
1536x640px
16:9
1312x736px
7:4
1344x768px

Lavender plants add to the calming ambiance. The lighting is soft and natural, coming from the left, creating a tranquil and inviting atmosphere perfect for wellness and relaxation. The setting exudes a sense of luxury and care, aligning with the product's high-end aesthetic.",
"negative_prompt": "pixelated, low quality",
"aspect_ratio": "16:9"
}
}Preference
Easy to use parameter to configure model settings to achieve the desired balance between generation speed and output image quality.
Can be set to "fast", "optimal", or "best".
If no preference is specified, "optimal" is used by default. But if negative_prompt is specified - "best"is used by default, since negative_prompt can be specified only with "best"preference.
{
"scene": {
"model": "v2",
"prompt": "Professional photo of a product. The background features a serene spa environment with natural wooden textures, soft white towels, and smooth pebbles. Lavender plants add to the calming ambiance. The lighting is soft and natural, coming from the left, creating a tranquil and inviting atmosphere perfect for wellness and relaxation.

Template-free v1 model options
v1 model also supports:
Custom prompts: Manual control
For more control over the background, provide your own prompt. Custom prompts must be between 3 and 2048 characters.
Example:
{
"scene": {
"model": "v1",
"prompt": "on a rugged mountain trail, scattered rocks, moss-covered ground, sunlight filtering through pine trees, rich earthy colors, warm light, dynamic perspective, high quality, professional product photography"
}
}Tips for effective custom prompts
Structure: Include place (surface), background, lighting, and mood for control.
Detail: Specify materials, textures, and context clearly (e.g., "rustic wooden table").
Clarity: Use precise terms—avoid vague words like "nice" or "pretty."
For more, see How to write prompts for AI product photos.
In addition it supports the following options:
Color
If you want to change the color of the background, you can specify the desired color in hexadecimal format. The color parameter defines the main color theme for the generated background scene.
{
"scene": {
"model": "v1",
"prompt": "on a rugged mountain trail, scattered rocks, moss-covered ground, sunlight filtering through pine trees, rich earthy colors, warm light, dynamic perspective, high quality, professional product photography",
"negative_prompt": "pixelated, low quality",
"aspect_ratio": "16:9",
"color": "#8fa782"
}
}Inference steps
The inference steps parameter controls the number of iterations the model uses for generation. Increasing the steps value generally improves image quality and detail but also increases processing time. Conversely, decreasing steps speeds up generation, potentially at the cost of some quality.
{
"scene": {
"model": "v1",
"prompt": "on a rugged mountain trail, scattered rocks, moss-covered ground, sunlight filtering through pine trees, rich earthy colors, warm light, dynamic perspective, high quality, professional product photography",

Template-based approach
In the template-based approach, you can use a sample image that will be used to generate a background similar to the image, and you can also use prompts to increase the likelihood of achieving the desired result.
Template image
AI Background API supports several options to provide sample images that will be used to generate background.
HTTP(S) URL
URL of the input image should be from 1 to 4096 characters. The image must be accessible by our system.
{
"scene": {
"template_url": "https://images.claid.ai/photoshoot-templates/docs/scene.png"
}
}Connected storage
You can connect Cloud Storage and use it as a source for images. Currently, our API supports AWS S3 and Google Cloud Storage.
After connecting your Cloud Storage, you can refer the storage name as an input.
{
"scene": {
"template_url": "storage://storage-name/path/scene.png"
}
}Input image file types
The API supports the following image formats as inputs: BMP, GIF, JPEG, PNG, TIFF, WEBP, AVIF, and HEIC.
Template mode
The template mode enables you to determine the degree of similarity between the background and the template image. You can select between lock mode to preserve maximum details, adjust mode to slightly adjust the background to better match the product, or transform mode to freely transform the background with prompt and color parameters. See Color and Prompts for more info.
transform
Template is transformed according to the prompt and color.
adjust
Template is slightly adjusted to the product and prompt.
lock
Template is preserved with maximum detail.
transform template mode is used by default.
{
"scene": {
"template_url": "storage://storage-name/path/scene.png",
"template_mode": "lock"
}
}Template viewpoint
The template viewpoint describes the camera position and tilt angle from which the photo was taken. Available viewpoints are listed below:
top
The view is top-down, looking down on the subject from above.
front
The view is horizontal, looking directly on the subject.
front viewpoint is used by default.
{
"scene": {
"template_url": "storage://storage-name/path/scene.png",
"view": "top"
}
}Prompts
You can use prompt and negative_prompt in the same way as in the template-free approach, but prompt is not a required parameter for template-based approach.
Color
You can use color in the same way as in the template-free approach, and color is not a required parameter for template-based approach as well. If specified, color will be used as the main color of the image sample-based background.
Inference steps
You can use steps in the same way as in the template-free approach, and again, steps is not a required parameter for the template-based approach. By default, each template_mode has an optimal steps value. And steps is not available for lock mode.

Limitations
The template image viewpoint (camera position and tilt angle from which the photo was taken) should match the viewpoint of the product image.
Product Shadows
Shadows generation mode covers the straightforward yet highly popular scenario in product photography. Creating a shadow effect for a product on transparent or on a solid Color can enhance its appearance. A product on a white background, for instance, looks better with a shadow.
{
"scene": {
"effect": "shadows",
"color": "#d3d3d3",
"view": "top"
}
}
The shadow generation effect requires View parameter. Color parameter is optional and omitting it will leave the background of the result image transparent.
Limitations
Background with product shadows does not require placement for the Object, so you don't need to pass any of placement related parameters in request payload. Object payload should be:
{
"object": {
"image_url": "https://images.claid.ai/photoshoot-templates/docs/product.png"
}
