Seededit V3 | Fast Image Editing API

SeedEdit v3 — /seededit-v3

SeedEdit v3 is a prompt-based image editing model for fast, high-quality transformations. Provide a source image and a short instruction, and the model performs targeted edits—such as changing hair, clothing, colors, backgrounds, or adding/removing elements—while keeping the overall composition and identity stable.

Key capabilities

Prompt-driven image editing from a single input image
Strong preservation of subject identity and scene structure for everyday edits
Works well for localized edits (hair, face details, clothing) and global adjustments (color/lighting)
Efficient for rapid iteration with controllable randomness via seed

Use cases

Portrait edits: hair color/style changes, light makeup tweaks, accessory edits
E-commerce variants: recolor outfits/products, background cleanup, consistent product shots
Marketing creatives: quick visual iterations (color mood, props, text-free adjustments)
Photo cleanup: remove small distractions, fix minor inconsistencies, improve overall clarity
Content localization: adapt visual details (e.g., wardrobe color/style) while keeping the same subject

Pricing

Output	Price
Per image	$0.027

Inputs

image (required): the source image to edit
prompt (required): the edit instruction

Parameters

prompt: what to change (and optionally what to keep)
image: input image (upload or URL)
guidance_scale: how strongly the edit follows the prompt (higher = stronger edit)
seed: random seed (-1 for random; fixed value for reproducible results)

Prompting guide

For clean edits, be explicit about what must stay the same:

Template: Keep [identity/pose/background]. Change [target]. Maintain [lighting/style realism].

Example prompts

Keep the face and pose unchanged. Change the hair to short, curly, rainbow-colored hair. Keep natural lighting and realistic texture.
Keep the subject identity and background unchanged. Change the jacket color to black and add subtle fabric texture.
Remove the object in the background and keep the subject sharp and unchanged.

Seededit v3 API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/bytedance/seededit-v3 with your input as JSON. The endpoint returns a prediction id; poll the prediction endpoint until status flips to completed, then read the output URL from data.outputs[0]. Examples for Seededit v3 below.

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/bytedance/seededit-v3" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY" \
  -d '{
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "image": "https://example.com/your-input.jpg",
    "guidance_scale": 0.5,
    "seed": -1,
    "enable_base64_output": false
}'

# Response includes a prediction id. Poll for the result:
curl -X GET "https://api.wavespeed.ai/api/v3/predictions/{request_id}/result" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY"

# When status is "completed", read the output from data.outputs[0].

Node.js example

// npm install wavespeed
const WaveSpeed = require('wavespeed');

const client = new WaveSpeed(); // reads WAVESPEED_API_KEY from env

const result = await client.run("bytedance/seededit-v3", {
        "prompt": "A cinematic shot of a city at sunset, soft golden light",
        "image": "https://example.com/your-input.jpg",
        "guidance_scale": 0.5,
        "seed": -1,
        "enable_base64_output": false
});

console.log(result.outputs[0]); // → URL of the generated output

Python example

# pip install wavespeed
import wavespeed

output = wavespeed.run(
    "bytedance/seededit-v3",
    {
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "image": "https://example.com/your-input.jpg",
    "guidance_scale": 0.5,
    "seed": -1,
    "enable_base64_output": false
}
)

print(output["outputs"][0])  # → URL of the generated output

Seededit v3 API — Frequently asked questions

What is the Seededit v3 API?

Seededit v3 is a ByteDance model for image editing, exposed as a REST API on WaveSpeedAI. SeedEdit 3.0 enables prompt-guided image editing for precise object, scene, and layout changes without disrupting composition. Ready-to-use REST API, high performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.

How do I call the Seededit v3 API?

POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID; poll the prediction endpoint until status flips to "completed", then read the output URL from the result. The playground generates a ready-to-paste code sample in Python, JavaScript, or cURL for whatever inputs you've set. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/bytedance/bytedance-seededit-v3.

How much does Seededit v3 cost per run?

Seededit v3 starts at $0.027 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.

What inputs does Seededit v3 accept?

Key inputs: `prompt`, `image`, `seed`, `guidance_scale`, `enable_base64_output`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/bytedance/bytedance-seededit-v3.

How long does Seededit v3 take to generate?

Average end-to-end generation time on WaveSpeedAI is around 16 seconds per request — measured across recent runs. Queue time scales with global demand; live status is visible in the prediction record.

Can I use Seededit v3 outputs commercially?

Commercial usage rights depend on the model's license, set by its provider (ByteDance). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
