Nano Banana 2 AI Image Model (Gemini 3.1 · Native 4K)
Nano Banana 2 is designed for high-resolution image generation and precise edits. Use text-to-image to create visuals from scratch, or image-to-image to transform existing photos with natural language instructions (background swaps, object removal, lighting tweaks, detail refinements). With multi-image references, extreme aspect ratios (including 1:8 and 8:1), and a Thinking-style reasoning flow for complex prompts, it’s a strong fit for marketing creatives, infographics, brand visuals, product shots, thumbnails, and storyboard frames.
Main Features of Nano Banana 2
Flagship capabilities for native 4K and complex prompts
Focused on five pillars—real-world grounding, multi-subject consistency, typography & localization, reasoning for instruction following, and native 4K with extreme aspect ratios—Nano Banana 2 fits production-grade marketing creatives, infographics, brand visuals, and storyboard workflows.
Real-World Knowledge (Google Search semantics)
Align visuals with real-world landmarks and facts by grounding generation with search semantics and image understanding. Great for infographics, educational posters, and concept work where accuracy matters.
Multi-Subject Consistency
Keep identity and key visual elements stable across a sequence. Use up to 14 reference images to better lock in characters, outfits, objects, and style for storyboards and series content.
Advanced Typography & Localization
Render clearer, more readable text for posters and infographics, and adapt creative concepts across languages for global campaigns with fewer “garbled text” reworks.
Thinking-Style Reasoning (Better instruction following)
Stronger multi-step reasoning for layered prompts helps improve spatial logic and object placement, keeping complex constraints closer to your structured requirements.
Native 4K + Extreme Aspect Ratios
Generate native high-resolution outputs (including 4096×4096) and specialized ratios like 1:8, 8:1, 1:4, and 4:1—ideal for banners, long images, and layouts that shouldn’t rely on harsh cropping.
How to use Nano Banana 2 for free
Open the Nano Banana 2 page, write your prompt, optionally add references, then set ratio and resolution to generate 4K-ready visuals for real projects.
Step 1: Open the generator and choose the model
Go to the AI Image Generator page (/image) or open /image/nano-banana-2 directly, then select Nano Banana 2 from the model menu.
Step 2: Enter a prompt (and upload references)
Write your text prompt. To keep characters or objects consistent, you can upload up to 14 reference images.
Step 3: Configure settings and generate a 4K image
Choose aspect ratio and resolution (1K/2K/4K), then generate and download the result for marketing creatives, infographics, or storyboard frames.
Frequently Asked Questions
Answers about Nano Banana 2 positioning, differences vs Pro, references, aspect ratios, and reasoning for complex prompts.
Nano Banana 2 is a Google AI image model built on the Gemini 3.1 Flash Image architecture. It targets fast generation with high-fidelity output, and it’s optimized for native 4K, consistency, and complex instruction following.
Nano Banana 2 is geared toward speed and cost-efficient iteration while keeping premium-quality output (including native 4K and multi-image consistency). Nano Banana Pro is better suited for highly technical, precision-critical scenarios and advanced design requirements.
This app uses a credit-based system. New users typically have some credits to try features. When credits run out, you can continue via subscription or credit packs.
Thinking (reasoning) controls how deeply the model analyzes complex prompts before generating. Higher reasoning tends to improve spatial logic and instruction adherence, but may increase generation time.
You can upload up to 14 reference images to improve consistency across characters, objects, style, and details.
It supports common ratios like 1:1, 16:9, and 9:16, plus extreme ratios such as 4:1, 1:4, 8:1, and 1:8 for banners and long layouts.
Yes. With a stronger typography tendency and 4K output, it works well for posters, marketing banners, infographics, and localized social assets that require readable text.
