Nano Banana Pro Text-to-Image: Gemini 3 Pro

Nano Banana Pro generates images with readable text baked in. Most AI models mangle words on posters, labels, and diagrams. This one gets them right.

Type a prompt describing what you want. Upload a reference image if you need edits or consistency across scenes. The model handles both generation from scratch and editing existing images through a single workflow. Runs in about 36 seconds.

How do you use Nano Banana Pro for image generation and editing?

Write your prompt, optionally upload a reference image, and hit Run. Nano Banana Pro (built on Gemini 3 Pro) generates or edits your image with accurate text rendering, multilingual support, and detailed creative controls for camera angles, lighting, and composition.

Prompt This is where your output lives or dies. Nano Banana Pro responds to specific creative direction better than vague descriptions. Want a cinematic look? Describe the exact shot: "low angle, f/1.8 shallow depth of field, golden hour backlighting." Need a product mockup? Describe the item, the setting, the lighting, and the text you want on the label. Need an infographic? Describe the content and the model draws from real-world knowledge to fill in accurate details.

Short prompts (under 25 words) tend to produce better compositions than long paragraphs. Structure your prompt around three things: subject, lighting, and style. Add detail from there.

Reference image (optional) Upload an image when you want to edit, extend, or restyle something you already have. The model keeps your subject consistent while applying the changes you describe. You can upload up to 14 reference images for complex compositions, and the model maintains resemblance for up to 5 different people across the output.

Want to adapt a product shot across five backgrounds? Upload the original and describe the new setting. Need the same design in a different aspect ratio? Upload and specify the new format.

Aspect ratio You can request specific aspect ratios in your prompt: 16:9 for email headers, 1:1 for Instagram, 9:16 for Stories. The model maintains text legibility and layout across formats, so you can adapt one concept for multiple platforms without reworking the design each time.

Language and text rendering Include text in your prompt in any language and the model renders it directly in the image. Tested with English, Spanish, Japanese, German, and Korean. Layout and formatting hold up across all of them.

For best text accuracy: put the exact text you want in quotation marks inside your prompt, keep headlines short and bold, and specify font style if it matters. Longer passages (over 25 characters) benefit from the two-step method: ask the model to generate the text content first, then request the image containing that text.

What is Nano Banana Pro good for?

Nano Banana Pro is built for creative work that needs accurate text in images, knowledge-backed diagrams, or precise visual direction. It handles product mockups, storyboards, infographics, and multilingual marketing assets in a single workflow, with results in about 36 seconds per generation.

Product photography and e-commerce get the clearest wins. You can generate packaging with ingredient lists, barcodes, and legal text at readable sizes. Phone case mockups with brand logos that wrap correctly around edges. Flash sale graphics with "30% OFF" text that reads the way you typed it. Then regenerate the same asset in different aspect ratios for email, social, and web banners without manual resizing.

For film and video pre-production, the model handles cinematography-specific prompts. Describe shots with proper terminology (focal length, depth of field, lighting direction) and get frames that match your vision. Storyboard panels with scene labels. Location scouting concepts from script descriptions. The model understands lighting, composition, and camera language better than most image generators.

Infographics and diagrams are where the real-world knowledge kicks in. Ask for a diagram of how solar energy works and you get one with accurate labels and correct flow. The model reasons about content, not patterns.

The catch: complex edits with major lighting changes (day to night) or heavy multi-image blending can produce unnatural results. Small faces and fine details sometimes miss. Always check text output for spelling on longer passages. For character consistency across many scenes, you may need a few iterations.

How does Nano Banana Pro compare to other AI image generators?

Nano Banana Pro's main advantage over models like Flux, DALL-E, and Midjourney is text rendering accuracy. It scores 94% on single-line text accuracy across languages, which is the highest among current image generation models. It also brings real-world knowledge and reasoning that typical diffusion models lack.

Where Flux and SDXL give you more control over the generation pipeline (samplers, schedulers, LoRAs, ControlNets), Nano Banana Pro trades that granularity for reasoning. You describe what you want in plain language and the model figures out composition, lighting, and factual accuracy on its own.

For pure artistic image generation without text, Flux and Midjourney may still produce more stylistically diverse results. For anything that needs readable text, accurate diagrams, or knowledge-backed content, Nano Banana Pro is ahead.

FAQ

Can Nano Banana Pro render readable text in AI-generated images?
Yes. Text rendering is its standout feature. Poster headlines, product labels, diagram annotations, and small-font legal text come out legible in multiple languages. For best results, keep text under 25 characters per element and put exact wording in quotation marks in your prompt. Proofread longer passages.

What resolution does Nano Banana Pro support?
The model generates up to 4K resolution. Start at 1K to get your composition right, then re-run the same prompt at 2K or 4K for the final output. High-resolution works well for product hero images, macro details, and print-ready assets where fine texture matters.

How is Nano Banana Pro different from the original Nano Banana?
Nano Banana Pro is built on Gemini 3 Pro. The original Nano Banana used Gemini 2.5 Flash. Pro has better reasoning, higher text rendering accuracy (94% vs 87%), real-world knowledge from Google Search grounding, and support for up to 14 input images. It is a full generation ahead for production work.

Can I use Nano Banana Pro for multilingual content and localization?
Yes. Generate product labels, marketing assets, and packaging in English, Spanish, Japanese, German, Korean, and more. The model renders text directly in images without breaking the layout. You can also generate in one language and then prompt the model to translate the text while keeping all other visual elements the same.

What are the best prompting tips for Nano Banana Pro?
Keep prompts under 25 words for clean compositions. Structure around three elements: subject, lighting, style. Use quotation marks around any text you want rendered in the image. Specify camera angle, focal length, and depth of field for cinematic results. For text-heavy images, use the two-step method: generate the text content first, then request the image.

How do I run Nano Banana Pro online?
You can run Nano Banana Pro online through Floyo. No installation, no setup. Open the workflow in your browser, upload your inputs, and hit run. Free to try.
