HUMAN FRAGMENTS editorial poster sample

Create a 9:16 editorial poster in the HUMAN FRAGMENTS visual system. Theme: [surfing / basketball / boxing / cake decorating] Subject: [gender, age, appearance, outfit] Action: [specific movement or handcraft] Scene: [location and environment] Title: [custom two-word title] Supporting line: [one short phrase] Year: 2026 Use oversized cropped typography as the main structural framework. The letters should act as windows that reveal the surrounding environment, while the main person remains visually complete in front of the type. Do not let the letters cut through the face, torso, arms, thighs, or other important parts of the body. Let one key action element break beyond the typography to create strong depth: 1. WAVE CUT — a surfer carving across a rising wave, with the board nose, hand, water spray, and curled wave breaking outside the letters. 2. RIM RISE — a basketball player reaching toward the hoop from a camera placed above the rim, with the basketball, hand, and hoop fully outside the letter masks and aligned naturally. 3. IMPACT FRAME — a boxer throwing a straight punch toward the camera, with the foreground glove enlarged and breaking beyond the typography while the gym remains inside the letters. 4. SOFT SWIRL — a graceful young woman decorating a cake, with the piping bag, hands, cake, and cream details extending beyond the letters while the bakery interior appears inside the type. Use realistic photography, believable anatomy, natural skin texture, strong foreground perspective, subtle paper grain, a warm off-white background, restrained colors, and clean editorial spacing. Keep the text minimal and freely placed: [Title] HUMAN FRAGMENTS [Short supporting line] 2026

为快速 1K 迭代而生,不是最终 4K 模型

Lite 是工作流里的低成本第一步:草拟、编辑、比较,然后把胜出的方向升级到更重的模型。

常规 Nano Banana 2 页面主打高分辨率生成、推理和完整场景。Nano Banana 2 Lite 的任务不一样:它让工作流保持轻量。需要多试几版提示词、快速做一次图生图修改,或在还不需要 2K/4K 时预览版式,都适合先用 Lite。输出固定为 1K,价格固定为 4 积分,失败任务会自动退回积分,因此它最适合作为更重模型最终渲染之前的快速第一轮。

Why the Nano Banana 2 Lite generator wins for draft AI images

Use Nano Banana 2 Lite when you need a fast 1K AI image lane, low credit AI image runs, and cheap prompt edit loops—not a final 4K print pass.

Fast 1K AI image drafts in one fixed lane

Nano Banana 2 Lite locks output at 1K so you can run many draft AI images without resolution guesswork—thumbnails, concept boards, social mockups, and layout previews. Skip print-scale waits until a direction is worth finishing elsewhere.

Low credit AI image runs at a flat 4 credits

Every Nano Banana 2 Lite generate or edit is a flat 4-credit run—the low credit AI image price that makes ten variants feel normal. Signup credits can cover a real free trial of the nano banana 2 lite generator before you buy a pack.

Cheap prompt edit without a heavyweight setup

Need a cheap prompt edit? Upload a reference and describe the change in plain words—background directions, recolors, quick style tests. The nano banana lite path keeps image to image light so you kill weak ideas before spending on a flagship model.

Nano banana lite generator → promote winners later

Treat the nano banana 2 lite generator as step one: lock the idea with draft AI images, then reuse the winning prompt on Nano Banana 2 or Pro when you need multi-subject Flash strength or photoreal finish. Lite is the bridge, not the final gallery print.

Nano Banana 2 Lite 细节

Nano Banana 2 Lite 在 Nano Banana 系列里适合什么位置?

把它当作快速、低积分的草稿模型来用。原始 Nano Banana 是更便宜的日常编辑模型,Nano Banana 2 是更高分辨率的 Flash 模型,Nano Banana Pro 是旗舰级最终作品模型。Lite 介于低成本编辑和高分辨率完成之间。

Nano Banana 2 Lite 和 fal.ai 上的 Nano Banana Lite 是同一个吗?

是的。SupaImagine 里显示为 Nano Banana 2 Lite,上游 fal.ai endpoint 名称是 Nano Banana Lite / Gemini 3.1 Flash Lite Image。页面同时保留这两个名字,方便你在不同平台识别同一个模型。

Nano Banana 2 Lite 支持 4K 吗?

不支持。当前 Lite 接入固定为 1K,也不提供分辨率选择。如果你需要 2K 或 4K,请在 SupaImagine 中切换到 Nano Banana 2 或 Nano Banana Pro。

Nano Banana 2 Lite 可以编辑上传图片吗?

可以。你既可以从提示词生成,也可以上传图片后用自然语言描述要修改的地方。每次运行会返回一张编辑结果,并保存到 SupaImagine 素材库。

Lite 每张图片需要多少积分?

Nano Banana 2 Lite 每次生成或编辑图片都需要 4 积分。新账号有 10 个 starter credits 可用于试用模型,付费计划可补充更多积分。

Nano Banana 2 Lite 结果可以商用吗?

付费计划下可以,生成或编辑结果可按 SupaImagine 条款用于商业项目。使用 starter credits 生成的内容用于测试模型,不包含商业授权。

Is it meant for final client delivery at print size?

No. Treat it as a draft lane. Promote the winning prompt to a higher model when you need photoreal detail or large-format resolution.

Can I use output commercially?

On a paid plan, yes — subject to SupaImagine terms. Starter-credit runs are for testing the model, not commercial licensing.
