You’ve probably seen how Google’s Nano Banana (Gemini 2.5 Flash Image) is going viral for its image generation + editing.

ByteDance’s Seedream 4.0 offers similar-or-better capabilities (generation + editing, reference consistency, up to 4K) in a unified model.

I built a free demo site — [seedream.best] — where you can test Seedream 4.0 yourself. Welcome to try, compare, feedback!
