ByteDance Seedream 5.0 Lite
Seedream 5.0 Lite — ByteDance Reasoning Image Model
The thinking tier of the Seedream line: multi-step visual reasoning, stable targeted edits, and 4K output at one flat price.
Seedream 5.0 Lite is ByteDance’s reasoning image model, released in February 2026 as the first Seedream that thinks before it draws. It plans a prompt in steps rather than rendering it in one shot, which pays off on complex scenes and precise edits. On Nano Banana AI, Seedream 5.0 Lite generates at 2K and 4K for a flat 30 credits per image, five credits less than Seedream 4.5.
What is Seedream 5.0 Lite?
Seedream 5.0 Lite is a unified multimodal model: understanding, reasoning, and generation run in one network. ByteDance calls the headline feature deep thinking. The model works through a complex prompt in steps before rendering, so multi-subject scenes, layouts, and instructions with several constraints come out coherent instead of averaged together.
Editing got specific upgrades over Seedream 4.5 Edit: better small-face rendering, more faithful skin texture, and stable non-edited regions. When you change one element of a photo, the rest of the image stays put instead of drifting. Attach up to four reference images here and the platform switches to the edit model automatically.
Despite the Lite name, it is not a stripped-down model. It is the fast, affordable tier of the Seedream 5.0 line, sitting below Seedream 5.0 Pro, which adds interactive precise editing and layer separation for professional design work.
On Nano Banana AI, the 2K tier runs standard quality and the 4K tier runs high quality, both at 30 credits. It needs a Premium plan for 2K; 4K unlocks on Pro. Eight aspect ratios are available, including 21:9 ultrawide.
