# Seedream 5.5 Edit > Seedream 5.5 edits images from text instructions and up to 10 reference images, with configurable output dimensions and support for transparent PNG backgrounds. ## Overview - **Endpoint**: `https://fal.run/bytedance/seedream/v5.5/edit` - **Model ID**: `bytedance/seedream/v5.5/edit` - **Category**: image-to-image - **Kind**: inference **Tags**: image-editing, multi-reference, transparent-background ## Pricing Billing is calculated per output image, including an input-image fee for each output generated. Each output costs **$0.03** at **1K** or **1.5K**, or **$0.0405** at **2K**, plus **$0.012 per input image per output**. For custom dimensions, the output rate is **$0.03** up to and including **2,610,000 pixels**, and **$0.0405** above that area. For example, with **2 input images**, one output costs **$0.054** at 1.5K or **$0.0645** at 2K; two outputs cost **$0.108** or **$0.129**, respectively. For more details, see [fal.ai pricing](https://fal.ai/pricing). ## API Information This model can be used via our HTTP API or more conveniently via our client libraries. See the input and output schema below, as well as the usage examples. ### Input Schema The API accepts the following input parameters: - **`prompt`** (`string`, _required_): The text prompt used to edit the image. - Examples: "Replace the product in Figure 1 with that in Figure 2. Seamlessly render the logo in Figure 3 into the product design, in a frosted glass texture." - **`image_size`** (`ImageSize | Enum`, _optional_): The size of the generated image. Total pixels must be between 921600 and 4624220, with aspect ratio between 1/16 and 16. Default value: `auto_2K` - Default: `"auto_2K"` - One of: ImageSize | Enum - Examples: "auto_2K" - **`num_images`** (`integer`, _optional_): Number of separate model generations to run with the prompt. Default value: `1` - Default: `1` - Range: `1` to `6` - **`output_format`** (`OutputFormatEnum`, _optional_): The file format of the generated image. Default value: `"png"` - Default: `"png"` - Options: `"jpeg"`, `"png"` - Examples: "png" - **`watermark`** (`boolean`, _optional_): Whether to add the provider's visible watermark. - Default: `false` - **`sync_mode`** (`boolean`, _optional_): If `True`, the media will be returned as a data URI and the output data won't be available in the request history. - Default: `false` - **`enable_safety_checker`** (`boolean`, _optional_): If set to true, the safety checker will be enabled. Disabling it requires account authorization; unauthorized requests are always checked. Default value: `true` - Default: `true` - Examples: true - **`background`** (`BackgroundEnum`, _optional_): `auto` lets the model choose from the prompt and output format. `transparent` returns an RGBA image and requires `output_format=png`. Default value: `"auto"` - Default: `"auto"` - Options: `"auto"`, `"opaque"`, `"transparent"` - **`image_urls`** (`list`, _required_): List of URLs of input reference images. Up to 10 images are supported; if more are sent, only the last 10 are used. - Array of string - Examples: ["https://storage.googleapis.com/falserverless/example_inputs/seedreamv45/seedream_v45_edit_input_1.png","https://storage.googleapis.com/falserverless/example_inputs/seedreamv45/seedream_v45_edit_input_2.png","https://storage.googleapis.com/falserverless/example_inputs/seedreamv45/seedream_v45_edit_input_3.png"] **Required Parameters Example**: ```json { "prompt": "Replace the product in Figure 1 with that in Figure 2.
