Nano Banana 2.1: Google's AI image generation and editing model
Nano Banana 2.1 is Google's image model family member that keeps Flash-level speed while improving visual design, mask-based edits, and subject consistency at up to 4K. Here is what it does for everyday creators and where UltraPix fits on Android.
Overview
Google released Nano Banana 2.1 in October 2026 across Gemini, AI Mode in Search, and developer tools. Public materials describe it as an upgrade path from Nano Banana 2: sharper design defaults, stronger text in layouts, and editing that can respect a marked region instead of redrawing the whole frame.
On consumer apps you describe what you want, or upload references, and pick resolution and aspect ratio. Creators use it for fashion editorials, product placement, relighting, sketch-to-render workflows, and multi-reference composites.
Nano Banana 2.1 on fal
Every image on fal.ai's Nano Banana 2.1 page was generated with Nano Banana 2.1 on fal—Flash speed with mask-based editing and stronger subject consistency, up to 4K.
Prompt
A fashion photograph on a salt flat covered by a thin layer of water that turns it into a perfect mirror: a model in a flowing butter-yellow silk gown walks toward the camera, her full reflection beneath her, the sky and soft clouds mirrored to the horizon, a vintage teal car small in the distance. Shot on 35mm film, soft high-key natural daylight from a low sun, pastel palette of teal, cream, butter yellow and rust, gentle halation and fine grain, whimsical surreal fashion-film art direction, calm and dreamlike.
Key features and capabilities
- Up to 4K still output with aspect ratios from square mobile frames to ultra-wide 8:1 banners.
- Subject consistency. Google documents up to four characters and ten objects staying stable across related images when you reuse references.
- Multi-reference compositing. up to fourteen reference images in one generation, useful for campaigns with people, products, and props together.
- Mask-based editing. mark a region in the input image and instruct the model to change only that area (for example adding a hot-air balloon inside a box).
- Relight and restyle. change time of day or artistic medium while keeping pose and layout.
- Optional web search grounding. when enabled, the model can use current web information for factual visuals (places, events, products).
- Thinking levels. minimal, medium (default), or high reasoning before render; high helps dense infographics and multi-step instructions.
Combine up to 14 reference images
Pass people, pets, products and props as separate references and Nano Banana 2.1 composes them into one scene. fal.ai's example uses six references—a portrait, a dog, a Land Rover, a hat, a basket and a kite—with up to four characters and ten objects held consistent per Google.
Mask-based editing
Mark the area to change and describe the change; fal.ai shows a hot-air balloon added inside the marked box with the box removed. The model, the car and their reflections stay in place—no separate mask parameter; the marked image is the input.

Typical workflows
Text-to-image: write a structured brief, subject, setting, lens, light, any on-image text in quotes, then generate. Image-to-image / edit: upload one or more references, state what must stay locked, then describe a single change per pass for cleaner results.
Product teams often generate a hero packshot, relight it for seasonal campaigns, then swap backgrounds for marketplaces. Portrait creators reuse one face reference across wardrobe or location changes. Architects feed rough sketches plus material notes to get concept renders.

Turn a sketch into a photorealistic image
fal.ai: give a rough drawing and a few words on materials and light—the cabin, deck, stairs, jetty and boat land where they were drawn. Useful for architecture, product and set-design concept renders.
Limitations to plan for
Nano Banana 2.1 generates still images, not video. Small text and dense infographics may need high thinking and iteration. Edited regions are regenerated to match the scene, they may not be pixel-perfect clones of untouched areas.
Billing on third-party platforms is token-based; resolution and reference count move cost more than prompt length. Always verify model names and capabilities inside the app you use, UltraPix exposes whichever image models are configured for your account.

How it relates to Nano Banana Pro and Nano Banana 2
Google positions Nano Banana 2.1 as the newest Flash-family upgrade with mask editing and improved consistency. Nano Banana Pro targets deeper reasoning and typography-heavy work at higher flat pricing on many hosts. Nano Banana 2 remains the faster, lower-cost sibling with broad aspect ratios and many reference slots.

Prompt
A surreal photograph of a lush wildflower valley where a giant woman in a cream linen dress lies asleep across the rolling green hills like part of the landscape, her auburn hair spreading into the flowers, tiny hikers and a vintage sage-green Land Rover on a dirt track winding past her shoulder for scale. Shot on 35mm film, soft high-key natural daylight from a low sun, pastel palette of teal, cream, butter yellow and rust, gentle halation and fine grain, whimsical surreal fashion-film art direction, calm and dreamlike.
