Seedream 5.0 belongs to ByteDance's Dola Seedream 5.0 generation on BytePlus ModelArk, which the official model catalog bills as a leading image generation model with enhanced reference consistency and improved generation quality for professional scenarios.
- It handles text-to-image, single and multi-reference image-to-image, and batch image generation, with streaming delivery, selectable PNG or JPEG output, and high-resolution results up to 4K in the series.
- Requests reach it on Synthorai through the platform's OpenAI-compatible API.
