• It allows creators to blend many elements, up to ~14 reference images, and even maintain consistent appearance for up to 5 different people in one composition. This makes it powerful for collages, mockups, group compositions, marketing materials, product visuals, etc.  
• Nano Banana Pro offers Strong product photography capabilities, useful for infographics, diagrams, brand materials, mockups, ads, storyboards, etc.  

How Much is Nano Banana Pro?

Google now offers the model under a tiered pricing structure, depending on resolution, platform, and usage level. Nano Banana Pro has a free trial, but the “Pro” and “Ultra” tiers require a monthly subscription fee, with costs varying based on usage and platform. This means casual users can explore the tool at no cost, while professionals and businesses can opt for higher-quality, higher-volume plans.

• For standard 1K/2K images: about US $0.13–$0.14 per image.  
• For 4K images: about US $0.24 per image.
• If you use “Batch mode” (for bulk or less time-sensitive generation), costs may be lower, e.g. 4K could drop to ~US $0.12 per image.

This pricing applies when you use Nano Banana Pro via API / developer platforms (e.g. AI Studio, Vertex AI) or any paid plan that bills per generation. So how can we access free-user generations with Nano Banana Pro? Check ways below.

Step 3. Open the Models section and inside the model list, scroll to the image generation section. Select Gemini 3 Pro Image, which contains the Nano Banana Pro engine.

Step 4. AI Studio offers two access paths: Playground UI with no code; ideal for testing prompts, styles, prompts with references, etc.; and API tab with ready-made Python/Node.js snippets for production integration.

Note: Free-tier credits refresh monthly (often $300 credits in trial + ongoing limited free credits afterward). API usage requires enabling billing after the trial expires, but you won’t be charged until you exceed free limits. If Nano Banana Pro does not appear, switch the project region to Global as rollout timing varies.

How to Use Nano Banana Pro to Generate Images?

No matter which platform you gain free access to Nano Banana Pro, Gemini app, Flow Labs, Adobe tools, or AI Studio, the core workflow for generating images with Nano Banana Pro remains consistent. Below is a step-by-step workflow that shows exactly how to generate an image in Nano Banana Pro.

Step 1. Input a focused prompt

Write one clear sentence that establishes subject, lighting, and style (see prompt templates below). Keep this first pass concise, Nano Banana Pro interprets compact briefs very efficiently.

Step 2. Attach reference media (optional)

Upload example images to guide look, color palette, or subject consistency. Nano Banana Pro allows you to upload up to 14 images and maintains the consistency and resemblance of up to 5 people.

Step 3. Pick output format

Set aspect ratio (square, vertical, horizontal) and target resolution (1K/2K/4K).

Step 4. Generate, review, iterate

Produce a batch of outputs, inspect them, then refine with short follow-up instructions, e.g., tweak lighting, tighten crop, or swap a background element. Use localized edit commands to change parts of the image rather than full regeneration. Once you have a suitable image, export it.

Generate Images in Nano Banana Pro with Proper Prompts

To unlock the full creative potential of Nano Banana Pro, you need more than basic descriptions. The model responds exceptionally well to prompts that define style, composition, lighting, and constraints. Below are ten actionable techniques to help you generate cleaner, sharper, and more consistent images with Nano Banana Pro.

1. Start with a Clear Subject Focus

State your main subject clearly. For example, say “a stainless-steel water bottle on a white background” instead of vague phrases. A focused subject ensures sharper, more consistent images.

2. Add Style or Art Direction Early

Specify style upfront: photorealistic, cinematic lighting, studio-quality product photo, or anime-style illustration. Early style cues improve consistency, especially for series of images.

3. Use Camera Terms to Control Composition

Photography terms like “35mm lens,” “top-down shot,” or “macro close-up” help the AI understand framing and perspective, producing professional-looking compositions.

4. Specify Lighting for More Realistic Results

Detail light type and direction: “soft diffused light,” “golden hour warm light,” or “hard shadows for dramatic effect.” Proper lighting enhances realism and depth.

5. Describe Texture and Material Clearly

Explicitly mention surfaces: “matte ceramic,” “smooth reflective metal,” or “textured linen fabric.” Essential for product photos or any scene requiring realistic materials.

6. Use Negative Prompts to Avoid Unwanted Artifacts

Prevent unwanted artifacts with phrases like “no extra limbs, no distortion, no text, no watermark.” Keeps outputs clean and reduces post-editing.

7. Use Multi-Sentence Prompts Instead of One Overlong Sentence

Structure your prompt by covering the subject in one sentence, style or camera in the next, lighting in another, and negative constraints at the end. Clear segmentation helps the model follow instructions accurately.

8. Give the Model a Purpose

Specify the image’s intended use: “for e-commerce listing,” “for character sheet,” or “for cinematic poster.” This guides composition, scale, and clarity.

9. Use Reference Art Directions (Non-Copyrighted)

Guide style safely: “3D Pixar-like lighting,” “retro 90s magazine photography,” or “K-pop fashion editorial look.” Improves lighting, colors, and composition.

10. Add Output Constraints for Better Control

Include constraints like “centered composition,” “plain white background,” or “high contrast.” Helps produce consistent, controlled results across multiple images.
