This improves factual accuracy for real places, products, logos, and people, helping outputs reflect how subjects actually look rather than approximations.
Nano Banana 2 vs Other Models - One Prompt
Task: A hyper-realistic 16:9 macro photograph of an oversized, open antique culinary codex resting on a dark velvet museum plinth. Left Page (The Living Diorama): The left side of the book is hollowed out like a secret compartment. Inside is a breathtaking 3D miniature scene. A highly detailed figurine of the dish’s inventor is captured mid-motion in a period-accurate kitchen. Around them are microscopic versions of the 10-15 key ingredients, each in its own tiny hand-blown glass vial or micro-wooden crate. Include miniature brass cooking tools specific to the era. The scene is lit from within the "pages" by a warm, magical amber glow. Right Page (The Technical Recipe): The right page is flat, aged parchment featuring elegant, faded Spencerian calligraphy and hand-painted watercolor illustrations. 1. Top: The dish name in both English and its native language, with the bold "Origin Date." 2. Middle: A vertical "Ingredient Blueprint" with hyper-detailed sketches of each raw component. 3. Bottom: A small, detailed "Origin Map" showing the specific city of birth, styled like a 19th-century cartographic inset. 4. Text: Visible, legible recipe steps written in ink that looks slightly raised on the paper. Style: Museum specimen photography. 85mm macro lens. The lighting should be a mix of cool gallery spotlights and the warm "internal" glow of the book's diorama. Extreme texture on the weathered leather binding and the tooth of the paper.

Yes. The Nano Banana 2 API renders legible, correctly spelled text directly inside generated images, which makes it reliable for posters, packaging, UI mockups, and marketing assets. It preserves font style, color, and layout, and keeps typography sharp even at native 4K resolution.
Nano Banana 2 is the speed and cost optimized tier built on Gemini 3.1 Flash Image, tuned for fast, high-volume generation and editing. Nano Banana Pro targets maximum fidelity and more advanced control for the most demanding, detail-heavy work. For most production workloads the Nano Banana 2 API offers the better price-to-performance balance, and on Atlas Cloud both tiers are reachable through the same unified API.
Use the Nano Banana 2 API as your default for everyday generation, editing, and high-volume work where speed and cost matter most. Switch to Nano Banana Pro for final-pass, text-heavy, or highly detailed compositions that need the highest possible fidelity. Since Atlas Cloud serves both models through one API and one key, you can route between them without changing your integration.
On Atlas Cloud the Nano Banana 2 API costs $0.08 per image on the standard tier and $0.04 per image on the developer tier, a 50% reduction. Pricing is transparent and charged per image with no subscription required, and new users get free credits to test before they spend. You only pay for what you generate.
No. Using Google's official API typically requires a Google Cloud billing account and an international credit card, which is a common barrier for individual developers. With the Nano Banana 2 API on Atlas Cloud you only need an Atlas Cloud account, so you can get a key and start building in minutes without any Google Cloud setup.
The Nano Banana 2 API supports 1K, 2K, and native 4K output, with native 4K reaching up to 4096x2304. Native 4K means images are generated directly at high resolution rather than upscaled, so detail stays sharp across the frame. Output size and aspect ratio are configurable, so you can target everything from square social posts to wide cinematic frames.
The Edit API brings image to image editing to the Nano Banana 2 API, using guided diffusion for precise stylistic transfers and structural modifications. You can adjust existing images with simple text instructions while the model preserves the parts you want to keep, and it accepts up to 14 reference images for complex compositions. Results return at up to native 4K, which suits iterative production and retouching workflows.
