Seedream 5.0 Image-to-Image - Starrise AI

Seedream 5.0 Image-to-Image is an image-to-image model from ByteDance’s Seedream series, available through the Starrise AI API.

When referencing external image URLs, if Volcengine takes more than 10 seconds to download the image, the request will time out. Ensure image URLs load quickly, or use Base64 encoding for large files.

Key Capabilities

Image-to-image — Generate images using reference images and text prompts
Sequential generation — Generate multiple images in a single request
Custom size — Flexible output dimensions
Watermark control — Optional watermark and logo configuration
