Google releases Nano Banana Pro, an upgraded AI image generation model built on Gemini 3 Pro that offers 4K resolution, improved text rendering, and professional editing capabilities, while raising concerns about increasingly realistic AI-generated content.

Google Unveils Nano Banana Pro with Professional-Grade Capabilities

Google has launched Nano Banana Pro, a significant upgrade to its popular AI image generation model that promises to deliver professional-quality results with enhanced capabilities. Built on the company's latest Gemini 3 Pro language model, the new tool represents a major leap forward in AI-generated imagery, offering features specifically designed for business and professional use cases .

The upgraded model introduces several key improvements over its predecessor, including the ability to generate images at resolutions up to 4K, compared to the original Nano Banana's 1024x1024 pixel limitation. Users can now create 2K or 4K images, though this enhanced quality comes at a higher cost - $0.139 for 1080p or 2K images and $0.24 for 4K images, compared to $0.039 for the original model's output

Enhanced Text Rendering and Professional Features

One of the most significant improvements in Nano Banana Pro is its ability to render legible text accurately, addressing a long-standing weakness in AI image generation. The model can now create complete infographics with proper text rendering, eliminating the garbled letters and strange misspellings that have historically plagued AI-generated images

Nicole Brichtova, a product lead for image and video at Google DeepMind, emphasized the importance of this advancement: "Even if you have one letter off it's very obvious. It's kind of like having hands with six fingers; it's the first thing you see"

. The improved text capabilities are powered by the switch to the more powerful Gemini 3 Pro underlying model.

The model also offers enhanced editing capabilities, allowing users to make precise adjustments to camera angles, lighting, depth of field, focus, and color grading without affecting other elements of the image. Users can blend up to 14 images and maintain consistency across up to five people in their outputs

Availability and Integration Across Google Services

Nano Banana Pro is being rolled out across Google's ecosystem of AI tools. The Gemini app now uses the new model for image generation by default, though usage limits vary by subscription tier. Free users receive limited access before being redirected to the original Nano Banana model, while Google AI Plus, Pro, and Ultra subscribers enjoy higher generation thresholds

The model is also integrated into Google Workspace applications including Google Slides and Vids, making it accessible for business presentations and corporate content creation. Additionally, developers can access Nano Banana Pro through the Gemini API, Google AI Studio, and the company's new IDE, Antigravity

AI Detection and Watermarking Measures

Recognizing the potential for misuse of increasingly realistic AI-generated content, Google has implemented several detection and identification measures. Images created with Nano Banana Pro continue to include embedded SynthID watermarks that Google's tools can detect, along with additional C2PA metadata for labeling AI images .

The Gemini app now features an AI detection capability, allowing users to upload images and ask whether they were generated by AI. While the system specifically detects Google AI-generated content through SynthID, this represents a step toward helping users identify artificial imagery .

Concerns About Realistic AI Content

Despite the technical achievements, the enhanced capabilities of Nano Banana Pro have raised significant concerns about the potential for misuse. Testing by various publications revealed the model's ability to create highly realistic images that could be mistaken for authentic photographs or professional designs

Particularly concerning is the model's ability to generate realistic-looking depictions of recognizable figures and create convincing infographics that could spread misinformation. While Google has implemented safeguards to prevent the creation of images featuring named celebrities or public figures, testers found ways to circumvent these restrictions by removing specific names from prompts

The model's enhanced text rendering capabilities, while beneficial for legitimate use cases, also eliminate one of the traditional methods for identifying AI-generated content. As one reviewer noted, "Those errors have been good for us when we look for signs of whether something was created with AI because the text would always be bungled. But nano banana pro almost entirely solves this problem, for better or worse"
