# Seedream > Seedream 5.0 Flash is a fast image generation and editing model, built for workflows where speed and budget matter. ## Overview - **Endpoint**: `https://fal.run/bytedance/seedream/v5/flash/edit` - **Model ID**: `bytedance/seedream/v5/flash/edit` - **Category**: image-to-image - **Kind**: inference **Tags**: realism, typography, stylized ## Pricing - **Price**: $0.027 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. 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 1024x1024 and 2048x2048, 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: `"jpeg"` - Default: `"jpeg"` - Options: `"jpeg"`, `"png"` - Examples: "jpeg" - **`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 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.
