# Bytedance Seedream V4.5 Edit > A new-generation image creation model ByteDance, Seedream 4.5 integrates image generation and image editing capabilities into a single, unified architecture. ## Overview - **Endpoint**: `https://fal.run/fal-ai/bytedance/seedream/v4.5/edit` - **Model ID**: `fal-ai/bytedance/seedream/v4.5/edit` - **Category**: image-to-image - **Kind**: inference **Tags**: stylized, transform ## Pricing - **Price**: $0.04 per images 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. For the title copy the text in Figure 3 to the top of the screen, the title should have a clear contrast with the background but not be overly eye-catching." - **`image_size`** (`ImageSize | Enum`, _optional_): The size of the generated image. Width and height must be between 1920 and 4096, or total number of pixels must be between 2560*1440 and 4096*4096. - Default: `{"width":2048,"height":2048}` - One of: ImageSize | Enum - Examples: "auto_4K" - **`num_images`** (`integer`, _optional_): Number of separate model generations to be run with the prompt. Default value: `1` - Default: `1` - Range: `1` to `6` - **`max_images`** (`integer`, _optional_): If set to a number greater than one, enables multi-image generation. The model will potentially return up to `max_images` images every generation, and in total, `num_images` generations will be carried out. In total, the number of images generated will be between `num_images` and `max_images*num_images`. The total number of images (image inputs + image outputs) must not exceed 15 Default value: `1` - Default: `1` - Range: `1` to `6` - **`seed`** (`integer`, _optional_): Random seed to control the stochasticity of image generation. - **`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 - **`image_urls`** (`list`, _required_): List of URLs of input images for editing. Presently, up to 10 image inputs are allowed. If over 10 images are sent, only the last 10 will be 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.
