Frequently Asked Questions

What is Seedream V4?

How should I write prompts?

Use concrete nouns + style + lighting + composition + quality tags. Example: 'A minimalist perfume bottle on a marble table, soft rim lighting, 85mm lens, editorial, high detail'.

Does it support aspect ratio or resolution control?

This app uses provider defaults. You can upscale or crop afterwards. Future updates may expose explicit aspect ratio parameters.

How fast is it?

Under typical load, small-to-medium outputs often finish in a few seconds. Times vary with provider load and prompt complexity.

How do I get consistent series?

Fix your seed, keep the subject description stable, and vary only one factor (e.g., lighting) per iteration.

Can I use the images commercially?

Review the provider’s license and your local laws. Generally you retain rights to your outputs subject to platform and provider terms.

Any safety limitations?

Prompts must follow content policy and provider rules. Avoid unsafe, illegal, or infringing content.
