Nano Banana 2 guide: Prompts, features, and examples

Google just dropped Nano Banana 2, the latest evolution of its wildly popular AI image generation model. Built on Gemini 3.1 Flash Image, Nano Banana 2 inherits the high-fidelity output that made its predecessor a hit, but with faster performance and better creative control. 

The model is now rolling out as one of the default image engines across the Gemini app, Google Search (via Lens and AI Mode), and Flow, Google’s AI-powered video tool. It’s also live on Freepik with unlimited generations at 1K and 2K resolution for Premium+ and Pro users. 4K generations consume credits.

If you’ve been using the original Nano Banana or Nano Banana Pro, the upgrade is significant. 

If you’re new to Google’s models, this guide will walk you through everything you need to know: what Nano Banana 2 actually is, what’s changed, how to write prompts that get results, where it excels, and how it stacks up against competing models in the rapidly evolving AI image generation space.

What Is Nano Banana 2?

Nano Banana 2 is Google’s third-generation AI image generation and editing model, launched on February 26, 2026. Technically, it is Gemini 3.1 Flash Image, but the “Nano Banana” name stuck after the original model debuted under that codename on LMArena’s crowdsourced evaluation platform in August 2025. It quickly reached the top spot in both text-to-image and image editing rankings before Google officially claimed it.

The model supports image generation at resolutions ranging from 1K to 4K across multiple aspect ratios. It handles both text-to-image and image-to-image workflows. This means you can generate entirely new visuals from a text description or upload an existing photo and modify it through conversational commands. Every image created with Nano Banana 2 carries a SynthID watermark, Google’s tool for identifying AI-generated content, and is interoperable with C2PA Content Credentials, the industry standard supported by companies such as Adobe, Microsoft, and OpenAI.

What’s new in Nano Banana 2? Key features

The jump from the original Nano Banana (and even from Nano Banana Pro in some ways) involves several meaningful improvements. Here are the standout features that define Nano Banana 2.

Faster generation without sacrificing quality

This is the biggest improvement. Nano Banana 2 runs on the Flash architecture, which means generation times are measured in seconds instead of the longer waits you’d get with Pro-tier models. Google engineered the model for ultra-low latency while retaining much of the visual quality that made Nano Banana Pro a favorite among professionals. For users who depend on rapid iteration ( testing prompt variations or producing content at scale), this speed advantage makes a real difference.

Stronger instruction following

One of the biggest frustrations with earlier AI image models was the gap between what you asked for and what you received. Nano Banana 2 has been refined to follow complex, multi-layered instructions with much greater precision. It respects detailed constraints and negative prompts more reliably, reducing the need for endless regeneration loops. If you describe a specific lighting setup, a particular camera angle, and a defined mood, the model is more likely to deliver that exact combination on the first try.

Enhanced character consistency 

Nano Banana 2 can maintain character consistency for up to five characters and preserve the fidelity of up to 14 objects within a single workflow. This is a critical upgrade for storytelling, storyboarding, and commercial projects where visual continuity across multiple frames matters. Previous models often drifted in facial features or clothing details across sequential generations; Nano Banana 2 holds these details far more reliably.

Improved visual fidelity

The model produces images with more vibrant lighting and sharper detail than its predecessors. Skin tones look more natural, reflections map more accurately, and material differentiation (like fabric, metal, glass, or skin) is way better. The decoding process has been refined to minimize common artifacts like visual distortions, logical inconsistencies, and blurring that affected earlier versions.

Best prompts for Nano Banana 2

The quality of your output with Nano Banana 2 depends heavily on how you write your prompts. The model responds well to natural language (write prompts as if you were briefing a human art director), but structuring your descriptions produces much more consistent results.

The prompt anatomy 

Every effective Nano Banana 2 prompt benefits from including these core components:

• Subject: who or what appears. 
• Action or state: what’s happening 
• Environment or setting: where the scene takes place. 
• Composition and camera: framing, angle, lens. 
• Lighting and mood: emotional and visual atmosphere. 
• Style: photographic, illustrative, cinematic, etc.
• Exclusions: what to avoid. 

You don’t need all of these for every prompt, but the more specific you are, the better the output.

Portrait and headshot prompts

For professional portraits, specifying about lighting and lens simulation gives you high-quality results. 

A prompt like “Professional businesswoman, confident stance, modern glass office, natural window light, corporate photography style, 85mm lens, shallow depth of field, high resolution, sharp focus on eyes” will produce editorial-grade headshots. 

Adding constraints like “avoid: casual attire, cluttered background, harsh shadows” tightens the output even more.

Product photography prompts 

Nano Banana 2 is great at generating studio-quality product visuals. Good prompts specify the product, the surface or setting, the lighting setup, and the commercial feel you’re going for. 

This is an effective prompt example: “Luxury leather handbag on marble surface, soft directional studio lighting, clean white background, commercial product photography, detailed texture rendering, professional grade, high-end aesthetic.” 

Including material-specific language (leather grain, brushed metal, frosted glass) helps the model render textures more accurately.

Scene and environment prompts

For landscapes, interiors, and atmospheric scenes, describing the mood and time of day matters just as much as describing the physical elements. For example:

 “Misty mountain valley at dawn, soft golden light breaking through low clouds, pine forests in foreground, wide-angle perspective, cinematic landscape photography, serene atmosphere” produces dramatically different results from a basic “mountain landscape” prompt.

Conversational editing prompts

One of Nano Banana 2’s best features is its ability to understand iterative and conversational edits. Instead of starting over when an image is 80 percent there, you can refine it with natural commands: “Keep the composition but change the lighting to golden hour,” “Replace the background with a neon-lit city street,” or “Remove the person on the left and extend the sidewalk.”

This edit-first workflow saves time and keeps the elements that already work.

Character consistency prompts 

For projects that need the same character across multiple scenes, the best approach is to create a reference sheet first. Generate two or three views of your character in a single session (front-facing, profile, three-quarter view), then use those images as references for later generations. 

Prompts like “Using @img1, place this character in a rainy Tokyo street, wearing the same outfit, cinematic lighting, low angle” maintain identity across differentcontexts.

Style transfer and creative prompts 

Nano Banana 2 handles style transfer well when you provide clear visual references. Prompts like “Change this image to a sleek, minimalist futurism style with all organic textures replaced by smooth white polymer and chrome, using cool sterile laboratory-white lighting, maintain the exact same composition” produce predictable transformations. 

The model also responds well to era-specific references, like: “1970s analog film grain, warm color palette, slightly overexposed highlights” or “90s disposable camera aesthetic, harsh flash, candid framing.”

Negative prompts and exclusions 

Ending your prompt with clear exclusions prevents common AI image problems. A simple addition like “Avoid: blurry, low quality, distorted, artificial, oversaturated colors, extra fingers, deformed hands” can improve output quality, especially for photorealistic images.

Best use cases for Nano Banana 2

The combination of speed, quality, and versatility of this model makes it suitable for a wide range of professional and creative work.

E-commerce and product visualization

Generating multiple product variations, lifestyle shots, and contextual displays without hiring photographers or renting studios is one of its most valuable commercial uses. 

Upload a product image and ask the model to place it in different settings (kitchen counter, outdoor table, minimalist shelf) with consistent lighting and commercial-grade polish. The 4K resolution support makes outputs ready for Amazon listings, Shopify stores, and print catalogs.

Social media content creation 

The model’s speed makes it ideal for high-volume social content production. You can generate platform-ready visuals for Instagram, TikTok, or LinkedIn in seconds. In addition, you can also maintain a consistent visual identity across posts and iterate quickly when creative direction shifts. 

The viral success of the original Nano Banana was driven largely by social media creators experimenting with action-figure transformations, retro photo styles, and magazine-cover simulations. Nano Banana 2 handles all these things even better.

Marketing and advertising 

Nano Banana 2 can produce commercial-grade assets at a fraction of traditional production costs, from hero images for landing pages to banner ads and email campaign visuals. Its improved text rendering means you can include legible headlines, taglines, and call-to-action text directly in generated images. Still, complex typography benefits from post-production refinement.

Storyboarding and sequential narratives 

The ability to maintain character consistency across up to five characters and 14 objects in a single workflow makes Nano Banana 2 a powerful tool for storyboarding, concept art, and pitch decks. Film pre-production teams, advertising agencies, and comic creators can generate sequential visual narratives with coherent characters and environments far more efficiently than before.

Photo editing and restoration 

Nano Banana 2 keeps its predecessors’ strength in conversational image editing. Remove unwanted objects, change backgrounds, adjust lighting, modify clothing or accessories, or restore old and damaged photographs through simple text commands. 

The precision of these edits (changing one element without disturbing the rest of the composition) remains one of the Nano Banana family’s key advantages.

Educational and informational content

Infographics, diagrams, step-by-step visual guides, and educational illustrations are all within Nano Banana 2’s capabilities. The model’s improved text rendering and spatial understanding mean it can generate visual content that organizes information clearly. Of course, fact-checking any data or text included in generated images remains essential.
