What Is Nano Banana 2 Lite?
Definition & Official Model Code
Nano Banana 2 Lite is the public nickname for Google's gemini-3.1-flash-lite-image model — officially documented as Gemini 3.1 Flash-Lite Image. It is the fast, low-cost tier of Google's Nano Banana family of image models, built for near-real-time, high-volume image generation and editing rather than maximum output quality. Nano Banana 2 Lite is an independent workspace built on top of this model — nanobanana2lite.me is an independent third-party service and is not affiliated with Google.
What It Can Do
Two core capabilities, both available from a single workspace.
Text-to-image generation
Describe a subject, scene or composition in plain language and generate a new image from scratch.
Prompt-based image editing
Upload a source image and describe a change — background, style, color, composition — to edit it with a prompt instead of manual tools.
Multiple reference images
Upload more than one reference image per request, though per official docs Lite is not tuned for heavy multi-reference or long multi-turn editing chains.
Speed and Cost Positioning
Nano Banana 2 Lite is explicitly the "fast and cheap" tier of the family: Google's own launch materials describe it as built for speed and near-real-time, high-volume workflows. In practice on Nano Banana 2 Lite, that means typical generations complete in ~4s generation — fast enough to iterate through several variations of an idea in the time a single higher-tier generation would take.
1K Resolution and Aspect Ratios
Nano Banana 2 Lite's official native output is Native 1K (1024px). Nano Banana 2 Lite generates images at native 1K (1024px) only — there is no higher-resolution output tier. It supports multiple aspect ratios at that same native resolution tier — see the Generation Workflow docs for the full per-ratio output table, the single source of truth for exact numbers on this site.
Best Use Cases
Lite fits any workflow where speed and iteration matter more than a maximum resolution ceiling.
Rapid concepting
Generate many quick variations of an idea before committing to one direction.
Social and web content
Native 1K is typically sufficient for feeds, thumbnails and web banners, where load speed matters more than a large native file.
High-volume batches
Product mockups, ad variant testing and prompt experimentation all benefit from Lite's lower per-image cost.
Prompt-based touch-ups
Small edits — background swaps, color changes, style shifts — on an existing image.
