## About Nano Banana Pro (T2I)

Nano Banana Pro is Google DeepMind's Gemini 3 Pro Image model, launched on November 20, 2025 in the same week as Gemini 3 itself. Where the original Nano Banana was tuned for speed, the Pro model applies Gemini 3's reasoning to plan a composition before drawing it, which is why Google demos lean on infographics, diagrams, and posters rather than simple scenes.

This page covers the text-to-image mode: generation from a written prompt, without reference images. On artifio.ai it is one of 100+ models available in a single workspace, paid per generation.

## Features

- Generates at 1K, 2K, or 4K resolution, a step up from the original Nano Banana's 1024x1024 ceiling.
- Supports a wide aspect-ratio menu on DeepMind's model page, including 1:1, 4:3, 5:3, 9:16, cinema ratios like 1.85:1 and 2.39:1, and extreme 4:1 and 1:4 banners.
- Renders legible in-image text at lengths from a tagline to a full paragraph, with stylized fonts and calligraphy, and can generate that text in multiple languages.
- Optional grounding with Google Search feeds real-time facts into a generation, which Google demonstrates with weather graphics and recipe infographics.
- Uses Gemini's world knowledge to produce factually structured images such as labeled diagrams and historically grounded scenes.
- Every output is watermarked with SynthID, and Gemini app users can ask the model whether an uploaded image is AI-generated.

## What people use it for

- Infographics and explainer visuals where the layout, labels, and data have to be right, sometimes pulled live from Search grounding.
- Posters, slides, and ads that need paragraph-length text rendered cleanly inside the image.
- Multilingual campaign variants generated directly in each target language.
- Cinematic concept frames in 2.39:1 or other film ratios at up to 4K.
- Diagrams for teaching material, from biology cross-sections to process charts.

## Reported strengths

- DeepMind's published comparison shows leading Elo scores for text-to-image generation at release, with a specific edge on infographic prompts.
- In-image text error rates mostly under 10 percent across languages, the best result in DeepMind's comparison set.
- Reasoning-first generation handles long prompts with many simultaneous constraints better than the Flash-tier models.
- 4K output and print-friendly aspect ratios make it usable for production assets, not just previews.

## Reported limitations

- Google's developer post is explicit that quality comes with higher cost and latency than the Flash-tier image models.
- Outputs on free and mid-tier Gemini surfaces carry a visible watermark; only the highest subscription tier removes it.
- Free Gemini app users have a limited generation quota before falling back to the original Nano Banana.
- Nano Banana 2, released February 2026, took over as Google's default image model, leaving Pro as the slower specialist option.
