Today Google releases Nano Banana Pro, also known as Gemini 3 Pro Image, a high-fidelity image model designed for developers who want to generate and edit studio-quality images. Interested in creating mockups, ad campaigns, or faithful infographics without losing creative control? This is built exactly for that.
What Gemini 3 Pro Image (Nano Banana Pro) offers
Gemini 3 Pro Image is the highest-quality member of the Gemini family for images, built for applications that demand precision and professional results. The version is rolling out in paid preview and is available via the Gemini API in Google AI Studio and in Vertex AI for enterprises.
- Outputs in 2K and 4K to meet production standards.
- Controls over visual physics: volumetric lighting, bokeh, camera, focus, and color grading.
- Improvements in
text rendering: it generates embedded text in images with high legibility and stylistic coherence. - Grounding with Google Search to incorporate real-world knowledge in real time.
This model combines image quality with real-world knowledge and context, useful for technical diagrams, historical maps, or educational materials.
Integrations and workflow for developers
It’s not just an isolated model: Google is integrating it into platforms and tools across the ecosystem to speed up development.
Google Antigravity: development agents can invoke image generation to create UI mockups, visual assets, and prototypes before writing code.- Integrations with Adobe and Figma for workflows you already use.
- Access via
Gemini APIin Google AI Studio andVertex AIfor enterprise-scale.
That means you can automate steps of the creative pipeline: from a brief to assets ready for human review.
Fine control and technical use cases
If you work on tools that need precision, Gemini 3 Pro Image provides technical controls that matter:
- Composition and photography: define lighting, lens, focal length, and depth of field.
- Character consistency: keeps likeness consistent for up to five people.
- Multiple references: combine up to six high-fidelity shots or mix up to fourteen standard inputs into a single composite image.
Practical cases: creating coherent ads that combine product and logo, generating e-commerce mockups, photo restoration, and local editing on infinite canvases.
Text, localization and visual logic
One of the standout improvements is the ability to handle text inside images more intelligently. Need a menu, sign, or document changed to another language without losing the original style? Gemini 3 Pro Image does that while preserving composition and the implicit typography.
Quick example: convert a brochure in English to French while keeping the texture, shadow, and layout of the original text using image-to-image.
This opens doors for:
- Multilingual marketing materials.
- Localized educational content.
- Dynamic advertising where text changes based on the target audience.
Grounding with Search and factual accuracy
When you enable grounding with Google Search, the model can fetch web information in real time to produce images that better reflect reality. That’s valuable for representations that require accuracy:
- Biological diagrams.
- Historical maps with updated data.
- Technical infographics with current figures.
Technically, this reduces “hallucination” errors by allowing the model to check its output against external sources at generation time.
Provenance and responsibility
Google includes SynthID directly in images generated or edited with Gemini 3 Pro Image. That means each image carries a digital mark indicating its AI origin, making traceability and transparency easier in media distribution.
The integration of digital marks helps maintain trust and identify AI-generated content in professional workflows.
Practical comparison: Nano Banana (2.5 Flash) vs 3 Pro Image
Gemini 2.5 Flash Image(Nano Banana): faster and cheaper, ideal for prototypes and high-load scenarios where latency matters.Gemini 3 Pro Image(Nano Banana Pro): higher quality, better text rendering and grounding, but with higher cost and latency.
Choose based on your needs: speed and cost vs quality and precision.
