Many teams reach a point where fast concept images look fine in a preview—yet fall apart the moment they’re used in real work. Lighting shifts after small edits. Text inside images is almost readable but not reliable. Assets don’t survive being placed on a presentation slide, proposal board, or large display.
RunDiffusion’s Nano Banana and Nano Banana Pro (a.k.a Nano Banana 2) exist because these issues show up at different stages of the creative process. Each model is designed to eliminate specific friction without slowing down your workflow.
Nano Banana
- Speed: Very fast iterations for bulk concepting and rapid exploration.
- Resolution: Optimized for on-screen use and boards; good for quick previews and internal reviews.
- Text reliability: “Good enough” when text is small or secondary; can distort if you rely on it heavily.
- Ideal use cases: Moodboards, concept exploration, internal comps, alternate looks you might throw away.
Nano Banana 2 (Pro)
- Speed: Slightly slower, tuned for quality over raw throughput.
- Resolution: Higher native resolution; holds up better for 4K boards, zooming, and print.
- Text reliability: Much cleaner, more legible text inside UI, labels, signage, and headlines.
- Ideal use cases: Final client deliverables, presentation boards, marketing visuals, anything that must look intentional at full size.
Early Exploration Needs Speed Not Overbuilt Tools
During the exploratory stage of a project, you need lots of options quickly. Waiting for a heavy, detail-focused model slows down architecture studies, product direction tests, visual theme exploration, and game concepting. Nano Banana is built for this stage.
Precision and Stability Become Essential During Finalization
Once a direction is selected, expectations change. Small structural inconsistencies become obvious. Clients expect clarity. Marketing assets must hold up under scrutiny. Stakeholders zoom in. Presentation boards and product layouts need visual structure that won’t drift mid-edit. This is where Nano Banana 2 Pro
When Text Inside Images Actually Matters
Many professional images are also communication tools architectural plans, product diagrams, iGaming UI elements, presentation boards, instructional graphics, and storyline frames. In these cases, text isn’t ornamental; it carries meaning.
This is where the models differ clearly:
- Nano Banana handles general composition and can place decorative or simple text when needed.
- Nano Banana Pro is designed to generate clearer, more accurate text inside the image, including headings, annotations, multilingual text, and detailed labels.
This makes Nano Banana Pro the better choice when the final asset must combine imagery and information with professional clarity.

Resolution: Screen-Ready vs Presentation-Ready
Teams frequently discover that concept-scale images are too fragile for real deliverables. They blur during zoom, lose detail in print, or require reconstruction in another tool.
Here’s how the models align:
- Nano Banana
- Ideal for on-screen review and internal documents.
- Produces fast, clear 1024px images suited for evaluating composition and direction.
- Nano Banana Pro
- Generates high-detail images up to 4K.
- Suitable for architectural boards, product launches, infographics, marketing materials, and large displays.
- Holds up under cropping, repurposing, and reuse across formats.
When resolution affects how the work will be received, Nano Banana Pro provides the necessary headroom.
