Generation image Seedream 5.0

Seedream 5.0 is ByteDance's image generation family, served on FlyAIgh through the Doubao API surface in two variants: Lite (3 credits, text-to-image) and Pro (3-6 credits, adds image-to-image editing with up to 6 reference images). Both are among the most versatile image models on FlyAIgh when it comes to aspect ratios — seven options including the ultrawide 21:9 and ultratall 9:21 ratios that most other models don't expose.

The 21:9 / 9:21 capability is the standout feature. For cinematic banner work, website hero images, vertical scroll experiences and any context where you need a more extreme ratio than the standard 16:9, Seedream is often the only option that doesn't require post-crop.

Seedream 5.0 Pro is ByteDance's production-grade image creation model: sharper realism, more controllable edits, and reference-driven generation — feed it up to 6 images plus a prompt to restyle, merge or precisely edit. Lite remains text-to-image only; if you're on Lite and need editing, switch to Pro, GPT Image 2, Nano Banana Pro or WAN 2.7 Pro.

Seedream is particularly strong at photorealism (faces, natural lighting, materials), Asian aesthetics and balanced composition. It is weaker than Midjourney v7 for distinctive artistic style and weaker than GPT Image 2 for in-image text rendering. Pick Seedream when aspect-ratio flexibility and photorealism matter.
