Google/gemini-3-pro-image-preview

Nano Banana Pro (Gemini 3 Pro Image, model ID gemini-3-pro-image-preview) is Google DeepMind's flagship image generation and editing model released in November 2025, built on the Gemini 3 Pro foundation model. As the successor to Nano Banana (Gemini 2.5 Flash Image), it delivers significant improvements in multimodal reasoning, real-world grounding, and visual synthesis fidelity.

The model's core breakthrough is bringing advanced reasoning into the image generation pipeline — it "plans" scenes by understanding physics, lighting, and compositional logic before rendering, producing results with professional-grade logical consistency and technical quality. It can also access real-time data via Google Search to generate content grounded in real-world information (e.g., weather maps, sports data, biological diagrams), dramatically reducing factual hallucinations.

Key Capabilities

• High-Fidelity Text Rendering: Industry-leading in-image text generation — renders clear, correctly spelled, stylistically diverse text directly within images across Chinese, English, Japanese, Korean and more, ideal for posters, menus, infographics, and UI mockups.
• 4K Ultra-High Resolution Output: Supports native 1K, 2K, and 4K resolution output to meet needs ranging from social media to print publishing.
• Multi-Image Fusion & Character Consistency: Accepts up to 14 reference images as input, maintaining facial consistency for up to 5 people or blending 6 high-fidelity reference shots into a unified composition.
• Studio-Quality Creative Controls: Fine-tune camera angles, depth of field, focus, lighting (e.g., day-to-night, bokeh effects), and color grading for professional photography-grade image control.
• Google Search Grounding: Connects to real-time Google Search data to generate data-driven visual content such as maps, charts, and infographics based on factual information.
• Multilingual Localization: Understands the semantic context of text within images, enabling direct cross-language translation of menus, signs, and documents while preserving original layout and artistic style.
• Precise Localized Editing: Select, refine, and transform any region of an image through natural language descriptions to add, remove, or replace elements.

Technical Strengths

Feature	Benefit
Reasoning-driven generation	Leverages Gemini 3 Pro's advanced reasoning to understand physics, lighting, and causal logic before rendering, producing more spatially and compositionally coherent results
Text rendering precision	Accurately renders everything from taglines to long paragraphs with multilingual and typographic style support, solving the "gibberish text" problem in AI-generated images
Native 4K resolution	Outputs 4K quality without post-processing upscaling — texture detail, color depth, and sharpness meet print and large-format display standards
World knowledge & real-time data	Combines Gemini 3 Pro's knowledge base with Google Search access for factually accurate and timely generated content
14-image visual context window	Simultaneously loads complete brand style guides (logos, color palettes, character sheets, etc.) to ensure generated results precisely match brand identity
SynthID watermarking	All generated or edited images are automatically embedded with an invisible SynthID digital watermark for AI content provenance
