Nano Banana Lite: Text to Image

HOW IT WORKS

Step 1. Write your prompt
Describe the subject, setting, mood, and style. Simple prompts get automatically expanded into a detailed scene by the built-in system prompt; detailed prompts are followed closely as written.
Works great with: scene descriptions · characters · concept art · stylized/illustrative portraits

Step 2. Pick your aspect ratio
Choose the shape that fits your output — 16:9 for widescreen, 1:1 for square, 9:16 for vertical, and so on.

Step 3. Set your generation options
Choose how many images to generate at once, lock or randomize the seed, and set output format.

Step 4. Hit run and download
Nano Banana Lite generates your image directly from the prompt in seconds.
Ready for: Photoshop · Figma · Canva · any editor

First time? Leave every setting as-is. The defaults (16:9 · seed randomized · PNG · thinking level off) are the right starting point for almost everyone.

RECOMMENDED SETTINGS

Quick-start guide. Find the goal that matches yours and copy the settings.

• Standard run (most people) — Start here — 16:9 · seed randomized · PNG · thinking level off. The right starting point for almost everyone.

• Reproduce a result you liked — Lock the seed to the number that produced it, instead of leaving it on randomize.

• Need multiple options fast — Raise num_images to generate several variations from one prompt in a single run.

• Prompt feels ignored or over-interpreted — Turn thinking_level on for more deliberate interpretation of complex prompts; leave it off for speed on simple ones.

• Content getting filtered unexpectedly — Adjust safety_tolerance and enable_safety_checker to match how permissive you need the output to be.

Prompt: Describe the subject, environment, lighting, and style directly — simple prompts are automatically enriched with composition and atmosphere detail by the system prompt, so you don't need to over-write it yourself.

USE CASES

🖼️ Stylized Character & Group Art Generate whimsical, illustrative, or clay-like character scenes from a text description alone, no reference image needed.

🎨 Rapid Ideation Produce several prompt variations quickly to explore different visual directions before committing to one.

📐 Any Aspect Ratio Generate directly in the ratio you need for social, print, or web without cropping afterward.

✍️ Text-in-Image Prompt for legible on-image text and have it rendered clearly as part of the scene.

WHAT WORKS BEST / WHAT TO AVOID

✅ Works great

• Clear, descriptive prompts with subject + setting + style

• Letting the system prompt auto-enhance simple ideas

• Locking a seed once you find a result worth iterating on

• Stylized, illustrative, or character-driven compositions

⚠️ May produce softer results

• Overly vague one-word prompts with high expectations for detail

• Very cluttered multi-subject scenes in one prompt

• Conflicting style instructions in the same prompt

• Leaving safety tolerance too strict for the intended content

FAQ

What is Nano Banana Lite? It's Google's fast image-generation model, served here through fal.ai. This workflow wraps it in a single text-to-image node with a built-in system prompt that improves composition, lighting, and detail automatically.

How is this different from the Nano Banana 2 Lite workflow? Same node layout and settings, but this one calls the original Nano Banana Lite model instead of the newer "2" version — the rest of the pipeline (prompt in, image out) is identical.

Does this workflow support image input or ControlNet? No — this graph is text-to-image only. There's no LoadImage node or ControlNet model in the pipeline, so structure (pose, edges, depth) isn't carried over from a reference image.

How do I get more consistent results across a batch? Lock the seed and keep the prompt identical, then only vary the parts you want to change (subject, style keyword, etc.).

Can I use the results commercially? Check Google/fal.ai's current terms for Nano Banana Lite outputs, since commercial usage rights depend on the model provider's licensing, not on Floyo itself.
