Feature Comparison
NB2 Hub
Faithful Text and Image Remix
This feature allows users to upload a reference image alongside a short text prompt. The Nano Banana 2 model intelligently preserves the core layout, composition, and lighting of the original reference while upgrading details, textures, and specific elements as directed. This is ideal for iterative design processes, such as refining product shots, updating user interface mockups, or enhancing comic panels without altering the foundational structure.
Crisp Text Inside Images
NB2 Hub excels at generating clean, legible on-image text, from headlines to full paragraphs, with support for multilingual typography. The model avoids common artifacts like blurring or halo effects around letters, ensuring text is sharp and integrated seamlessly into the visual. This capability is perfect for creating professional posters, advertisement creatives, social media covers, and any asset requiring embedded textual information.
Multi-Reference Fusion & Identity Consistency
This advanced feature enables the fusion of elements from multiple uploaded reference images into a single, coherent output. Crucially, it maintains strict consistency for characters, products, logos, and other brand elements across generated shots. This is essential for creating cohesive storyboards, multi-angle product sets, or surreal landscapes that combine distinct visual inputs into a unified scene.
