Nano Banana model family

Choose the right Nano Banana variant for a scientific image task

The Nano Banana name covers three distinct options in SciFig. Compare their live limits before choosing fast text generation, multi-reference editing, or higher-quality image work.

Branching scientific diagram of cell differentiation — Nano Banana 2Fast multi-reference edits

One family, three product profiles

Nano Banana 2 is preselected below because it combines text-to-image, image-to-image, multi-reference input, and resolution controls. Pro emphasizes higher-quality image work, while the base model is a lightweight text-only option.

Scientific cross-section of a battery showing ion transport — Materials process cross-section
Test component consistency, directional flow, and technical spatial organization.

Where this family fits well

Generating several visual directions quickly before committing to a layout
Revising an existing draft while preserving visual cues from reference images
Testing square and unusually wide or tall compositions
Moving between a lightweight option and more capable editing variants

What to plan around

The three variants do not share the same modes, input limits, or resolution controls.
A reference image can guide appearance, but it does not make the scientific content correct.
Dense labels, pathways, and exact structures still require author correction.
Choose a specific variant from the live capability table rather than relying on the family name alone.

Provenance: SciFig reads these limits from its Kie integration and shared model registry. The public panel may accept fewer reference images, so use the active generator controls as the current product limit.

Tasks to test across the family

These examples show useful comparison tasks, not certified model benchmarks. Run the same prompt through different variants to compare composition, detail, and editability.

Branching hierarchy

Compare how variants preserve repeated visual elements and a clean branching structure.
