Seedream V4 Edit (Bytedance)

Frequently Asked Questions

What inputs are required?

An input image and a text prompt are required. Optionally adjust guidance_scale and seed.

How are results returned?

Results are returned as image URLs. You can download them after generation.

What does guidance_scale do?

It controls how closely the output follows your instruction. Lower values allow more freedom; higher values increase adherence (range 0.0–1.0).

What edit types work best?

Localized object changes (add/remove/replace), style transfer, color/material adjustments, background swaps, and subtle geometry edits with strong identity preservation.

How to write effective edit instructions?

Use 'action + object + target feature'. Example: 'Replace the poster headline with “GRAND OPENING” in bold sans-serif, centered, white text'.

Do I need a mask?

This app does not require masks. If a precise region is needed, describe the region explicitly (e.g., 'only the mug logo').

How to avoid over-editing?

Keep instructions minimal, reduce guidance_scale if global changes appear, and focus on one change per iteration.

Can I chain multiple edits?

Yes. Apply small edits iteratively and re-upload the previous result for the next step to maintain control and quality.

Commercial usage?

Review provider terms. For brand assets or faces, ensure you have the necessary permissions before publishing.
