What Is Nano Banana?

Nano Banana is Google's name for its conversational AI image generation capability, powered by their Gemini image models. Available through gemini.google.com, it lets you generate, edit, and iterate on images through natural conversation β€” rather than filling out forms or writing technical prompts.

What sets Nano Banana apart from other image generators is its ability to maintain character consistency across multiple images. You can generate a character once, then ask to see them in a new setting, a different expression, or a new pose β€” and the character looks recognizably the same. The current version (Nano Banana 2, based on Gemini 3.1 Flash Image) can maintain up to 5 people and 14 objects consistently across a workflow.

It also integrates with Google Flow, meaning images you generate can be directly animated into video clips using Veo.

🍌 Why "Nano Banana"?

It's Google's playful internal codename for their image generation models β€” starting with Gemini 2.5 Flash Image (August 2025), then Nano Banana Pro (November 2025, Gemini 3 Pro), and now Nano Banana 2 (February 2026, Gemini 3.1 Flash Image). The name has stuck as users have adopted it, and Google has leaned into it.

Educational Applications

  • βœ“
    Visual Storyboarding. Create a consistent cast of characters for a story, fairy tale, or historical narrative. Students can illustrate their own writing with characters that look the same panel to panel.
  • βœ“
    Children's Books & Illustrated Stories. Teachers and librarians can generate an illustrated story with a recurring protagonist β€” same child, dog, or fantasy creature across all illustrations.
  • βœ“
    Media Literacy & Critical Analysis. Use Nano Banana to demonstrate how AI constructs images β€” exploring bias, representation, and the choices embedded in generative systems.
  • βœ“
    Science & Social Studies Visuals. Illustrate abstract concepts, historical scenes, or scientific processes by describing them conversationally. Ask for revisions ("make the volcano bigger", "show it from a bird's eye view").
  • βœ“
    Bridge to Google Flow. Use character-consistent images as starting frames for Google Flow animations β€” creating animated explainer clips or short story sequences with minimal effort.
  • βœ“
    Art & Design Classes. Explore style iteration β€” ask students to prompt the same scene in different artistic styles (watercolour, graphic novel, ukiyo-e) and compare the outputs.

Cautions & Considerations

⚠️ Things to Know

Representation & Bias. Like all image generators, Nano Banana reflects biases present in its training data. Prompts involving people, culture, or history may produce stereotyped results. Use these moments for critical discussion.

Consistency Isn't Perfect. While character consistency is much better than older tools, results can drift β€” especially with complex poses or unusual angles. You may need to remind the model to "keep the character details exactly the same."

Copyright & Ownership. AI-generated images exist in a legal grey area regarding copyright. Avoid prompting in the style of specific living artists. If using images publicly, check your institution's AI use policy.

Student Privacy. Avoid using real student photos as reference images. Use fictional or consented characters only in educational contexts.

Sample Prompts to Try

Copy and paste these into Gemini at gemini.google.com

πŸ“Œ Character Creation (Starting Point)
Create an illustration of a young girl named Maya, around 10 years old, with short black hair, round glasses, and a red hoodie. She's standing in a school hallway looking curious. Warm, friendly illustration style.
This establishes your character. Use it as the reference for all follow-up prompts.
πŸ“Œ Character Consistency (Follow-up)
Now show Maya at a public library, sitting at a table with books open around her, looking excited about something she just found. Keep all her character details exactly the same β€” short black hair, round glasses, red hoodie.
Always remind Nano Banana to keep character details consistent when changing scenes.
πŸ“Œ Historical/Social Studies Scene
Create an educational illustration showing life in a 19th-century Canadian prairie settlement: a wooden homestead, a family working in a garden, horses in a field, golden wheat, wide open sky. Warm and realistic illustration style, suitable for a middle school textbook.
πŸ“Œ Science Visual
Create a clear educational diagram showing the water cycle: evaporation from the ocean, cloud formation, precipitation as rain and snow, and runoff into rivers. Label each stage. Clean, colourful, suitable for a Grade 5 science class.
πŸ“Œ Style Exploration (Art Class)
Illustrate a crow sitting on a winter fence post in the style of Japanese ukiyo-e woodblock prints. Bold lines, flat colour areas, and a sense of calm stillness.
Try the same subject in 3–4 different art styles and compare the results with students.

πŸ’‘ Note on These Examples

The images below are examples of what Nano Banana can produce for educational purposes. Use these prompts as starting points β€” then edit and iterate conversationally to refine details, add labels, or change the style.

πŸ”¬ Biology β€” Human Cell
Create a detailed, colourful educational illustration of an animal cell in cross-section. Show clearly visible and labelled organelles including: nucleus (with nucleolus), mitochondria, endoplasmic reticulum (rough and smooth), Golgi apparatus, ribosomes, cell membrane, lysosomes, and cytoplasm. The style should be clean, textbook-quality illustration with a white background. Each organelle should be a distinct, vibrant colour. Suitable for a high school or first-year university biology course.
Follow up with: "Now show a plant cell with the same style, adding a cell wall, central vacuole, and chloroplasts."
βš—οΈ Chemistry β€” Periodic Table Families
Create a visually engaging educational poster showing the main groups of the periodic table. Highlight the alkali metals, alkaline earth metals, transition metals, halogens, and noble gases in distinct colours. Include example elements for each group with their symbol, atomic number, and a small icon representing a key property or use. Clean infographic style, white background, suitable for a chemistry classroom wall.
🌍 Earth Science β€” Plate Tectonics
Create an educational cross-section diagram showing the three main types of tectonic plate boundaries: convergent (showing subduction), divergent (showing rift and mid-ocean ridge), and transform (showing lateral slip). Each type should be clearly illustrated in a separate panel with labelled arrows showing direction of plate movement, plus labels for: oceanic plate, continental plate, magma, subduction zone, earthquake zone, and rift valley. Bright, clear illustration style for Grade 9–10 science.
🧲 Physics β€” Electromagnetic Spectrum
Create an educational diagram of the electromagnetic spectrum. Show the full range from radio waves to gamma rays, displayed as a continuous horizontal band with wavelength decreasing left to right. Label each region clearly: radio, microwave, infrared, visible light (showing rainbow colours), ultraviolet, X-ray, and gamma rays. Include examples of real-world uses for each type. Add a wavelength scale below. Clean, modern infographic style suitable for a physics class.
πŸ“Š Social Studies β€” Concept Web
Create a visual concept map showing the factors that caused World War One. In the centre, place "WWI (1914–1918)". Branching out, show four main causes: Militarism, Alliances, Imperialism, and Nationalism β€” each in its own coloured bubble with 2–3 brief supporting points or examples. Connect related concepts with arrows. Clear, clean educational infographic style. Dark background with bright coloured bubbles for visibility.
The "MAIN" acronym (Militarism, Alliances, Imperialism, Nationalism) is a common teaching framework for WWI causes.
πŸ”’ Math β€” Visual Proof
Create a clean visual diagram illustrating the Pythagorean theorem (aΒ² + bΒ² = cΒ²). Show a right triangle with sides labelled a, b, and c. Around each side, draw a square with area labelled (aΒ², bΒ², cΒ²). Use distinct colours for each square. Add a simple visual showing that the two smaller squares combine to equal the larger one. Minimalist, elegant style suitable for a middle school math classroom. White background.
🧬 Biology β€” DNA Double Helix
Create a photorealistic, educational illustration of a DNA double helix. Show the sugar-phosphate backbone as two ribbon-like strands twisted around each other. Show the base pairs as rungs connecting the strands, with adenine-thymine pairs in one colour (blue/yellow) and guanine-cytosine pairs in another (green/red). Add clear labels for: double helix, sugar-phosphate backbone, base pairs, nucleotide, and show the direction labels 3' and 5'. Clean, scientific illustration style with a dark background for contrast. Suitable for a Grade 11–12 biology class.
πŸ—ΊοΈ Geography β€” Indigenous Land (with caution)
Create a respectful, educational map illustration of the major Indigenous language groups of the Canadian prairies, including the Cree, Nakoda (Stoney), Saulteaux (Ojibwe), Assiniboine, and Blackfoot Confederacy territories. Use soft, muted colours to show approximate traditional territories with clear, readable labels. Include major rivers and lakes as geographic reference points. Map style should feel respectful and cartographic rather than decorative. Add a note: "Approximate traditional territories β€” boundaries are fluid and not fixed."
⚠️ Always verify AI representations of Indigenous territories against authoritative sources. Consider using resources like native-land.ca for accuracy.
