Nano Banana Pro Is Now available on OneRouter

Nano Banana Pro Models Are Now Live

We’re excited to introduce NanoBanana 2, the state-of-the-art image generation model, now live on OneRouter. With two powerful endpoints for text-to-image and image-to-image, NanoBanana 2 gives creators unparalleled control over visual output.

• nano‑banana‑pro‑text‑to‑image – Generates high‑quality, detailed images from text descriptions with improved realism and artistic control.

• nano‑banana‑pro‑image‑to‑image – Transforms or refines existing images based on prompts, enabling style transfer, image editing, and creative remixing.

1. Character Consistency

One of the standout capabilities of NanoBanana Pro is its exceptional character consistency. Whether you're designing recurring characters for a story, a brand, or a creative project, the model preserves identity across poses, lighting setups, and scenes. This makes it ideal for long-form content creation, marketing campaigns, or any workflow that relies on predictable, repeatable character appearance.

2. Text Rendering

Text inside generated images has traditionally been a challenge, but NanoBanana Pro changes the game. The model randers clean, legible, and accurate text, even in complex environments like signage, labels, packaging, or UI screens. This unlocks new possibilities for product mockups, advertising concepts, and design prototypes without the usual post-processing struggles. The magazine example below showcases how the model can handle the previously impossible task of generating long paragraphs of text.

3. Product Consistency

For creators working with physical goods or branded objects, NanoBanana Pro delivers highly reliable product representation. Logos, shapes, materials, and proportions remain stable across different angles and backgrounds. This makes it especially powerful for e-commerce visuals, marketing imagery, and industrial design explorations where precision and reproducibility matter.

4. 2K & 4K Resolution

NanoBanana Pro was built for clarity. With output options in both 2K and 4K resolution, the model enables ultra-sharp, production-ready imagery suitable for print, large displays, and high-detail digital content. Whether you're generating cinematic scenes or crisp product close-ups, the visual fidelity holds up even under scrutiny.

5.Reference images

To give creators maximum influence over the final result, Nano-Banana-Pro supports up to 10 reference images. This allows you to define characters, textures, environments, and layout details with pinpoint accuracy. You can dial in the exact look and feel you want, while the model harmonizes these elements into a high-quality, coherent output.
