Text prompt describing the edit to apply to the reference image(s).

  • https://media.modelrunner.ai/4ZQTl9vZZdFI944B05Cuu.jpeg

Reference image(s) to edit or use for reference-based generation. Required — provide 1 to 10 images. Reference images are free on this tier.

Output image dimensions as WxH pixels, which set both resolution and aspect ratio. All options are 2K-class (~3.7-4.3 megapixels); this tier does not produce smaller images. Match the aspect ratio to your source image to avoid unwanted cropping. Price is flat regardless of the value chosen.

Use Seedream 5.0 Lite Image Editing from Claude & Cursor (MCP)

Point Claude Code, Claude Desktop, Cursor, or any MCP client at the ModelRunner MCP server and Seedream 5.0 Lite Image Editing becomes a tool your assistant can call directly — it authorizes via OAuth (no API key in config) and runs this model with the run_model tool using the endpoint bytedance/seedream-v5/edit.

MCP client config (Claude Desktop, Cursor)

{
  "mcpServers": {
    "modelrunner": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.modelrunner.run/mcp"]
    }
  }
}

Claude Code

claude mcp add --transport http modelrunner https://mcp.modelrunner.run/mcp

Then ask your assistant, for example: “Run bytedance/seedream-v5/edit on ModelRunner to generate image”. MCP setup guide.

Model Details

Model Details

Seedream 5.0 Lite Image Editing applies a written instruction to one or more images you supply. Give it up to ten reference images plus a prompt and it edits, restyles, or composites them into a single coherent 2K-class result. It is the fast, affordable tier of the Seedream 5.0 line: reference images are free, and every output bills the same flat price per image.

## Best for - Editing or restyling a photo from a text instruction while keeping the rest intact - Reference-based generation: transferring style, identity, or product details from up to 10 images - Compositing several products, people, or scenes into one image - Adding, removing, or replacing objects in an existing image

## Choose another model when - You have no reference image and want to generate from a prompt alone — use `bytedance/seedream-v5/text-to-image` - You need the highest edit fidelity, or output below 2K — use `bytedance/seedream-v5-pro/edit` - You need a video rather than a still image — use an image-to-video model

## Tips - Pass the source image(s) in `image_urls` and describe the change precisely, stating explicitly what should stay unchanged - Reference images are free on this tier — supply up to 10 without affecting the price - `size` sets both resolution and aspect ratio. Every option is 2K-class; this tier does not produce smaller images. Match the aspect ratio to your source image to avoid unwanted cropping - Put any text you want rendered inside quotation marks in the prompt for the most accurate spelling

To run via the ModelRunner JavaScript client: ```js import { modelrunner } from "@modelrunner/client";

const result = await modelrunner.subscribe("bytedance/seedream-v5/edit", { input: { prompt: "replace the background with a sunlit studio, keep the subject unchanged", image_urls: ["https://media.modelrunner.ai/example-photo.jpg"], size: "2048x2048", }, }); ```
