What Is the Nano Banana 2 Lite API?
Nano Banana 2 Lite is Google’s efficiency-focused image model, officially named Gemini 3.1 Flash-Lite Image. It became generally available in June 2026 under the stable ID gemini-3.1-flash-lite-image. Text and image inputs support both generation and natural-language editing.
Google reports approximately four seconds for a 1K text-to-image result. This makes the model a practical default for concepts, previews, thumbnails, social variants, and product-scene drafts before selected assets move to a higher-resolution model.
Is Nano Banana 2 Lite the Same as Gemini 3.1 Flash-Lite Image?
Yes. Nano Banana 2 Lite is the product name; Gemini 3.1 Flash-Lite Image is the official model name. Do not confuse it with the text-only Gemini 3.1 Flash-Lite model or the full Nano Banana 2 model (gemini-3.1-flash-image).

Best Nano Banana 2 Lite Use Cases
Interactive features: Return a usable 1K draft inside creative apps, learning tools, games, or generative interfaces.
Creative testing: Produce ad concepts, thumbnails, product backgrounds, or social variants at a low cost per rejected draft.
Targeted edits: Change a background, color, object, or style with an input image and a concise instruction.
Pre-production: Explore storyboards or campaigns, then render approved directions with a higher-resolution model.
Nano Banana 2 Lite vs Nano Banana 2, Seedream 5.0 Pro, and GPT Image 1.5
| Model | Output options | Workflow strength | Choose it when… |
|---|---|---|---|
| Nano Banana 2 Lite | 1K only | Fast drafts, affordable volume, lightweight edits | You need many usable images quickly and do not require 2K or 4K output |
| Nano Banana 2 | 0.5K, 1K, 2K, and 4K | General-purpose generation, search-grounded imagery, multi-reference work | You need higher resolution, current web context, or stronger character and reference consistency |
| Seedream 5.0 Pro | 1K, 1.5K, and 2K | Dense layouts, multilingual text, precise element placement, multi-reference editing | You are creating posters, product graphics, technical visuals, or layout-sensitive assets |
| GPT Image 1.5 | 1024×1024, 1024×1536, and 1536×1024; low, medium, and high quality | Detailed instruction following and controllable generation or editing | Your workflow needs quality tiers, portrait/landscape size control, or compatibility with OpenAI image tooling |
Nano Banana 2 Lite vs Nano Banana 2
Choose Lite when speed and cost matter more than maximum resolution. Choose Nano Banana 2 for 2K or 4K delivery, Search grounding, and reference-heavy work.
Nano Banana 2 Lite vs Seedream 5.0 Pro
Use Lite for fast 1K ideation and bulk variants. Choose Seedream 5.0 Pro for denser compositions, multilingual copy, exact placement, or output above 1K.
Nano Banana 2 Lite vs GPT Image 1.5
Lite offers one inexpensive 1K tier. GPT Image 1.5 provides three output sizes and three quality levels, making it a better fit when those controls or an existing OpenAI workflow matter more.
What to Know Before Using Nano Banana 2 Lite in Production
The Lite label represents a real trade-off: output is limited to 1K, and Search grounding is unavailable. Although Google documents up to 14 object references, it says this model is not optimized for reference-heavy or long sequential editing workflows.
Review small typography, long text blocks, character identity, and left-versus-right placement. Google lists these as remaining limitations, so keep visible copy short and verify every final image.
Nano Banana 2 Lite API Prompt Patterns
Fast product variant
Create a 1K studio product photo of [product] on [surface], with [lighting], [camera angle], and [background color]. Keep the product shape, label, and logo unchanged. No extra objects.
Targeted image edit
Using the provided image, change only [specific element] to [new description]. Preserve the subject, camera angle, lighting, composition, and all other objects exactly as they are.
Short-text social graphic
Create a [aspect ratio] social graphic for [topic]. Place the exact headline “[short headline]” in large, high-contrast type. Use [palette], one clear focal subject, generous spacing, and no additional text.
For dense posters, long paragraphs, repeated characters, or multi-round precision edits, route the approved concept to a model with more resolution or stronger reference handling.
Why Access Nano Banana 2 Lite on GPTProto?
GPTProto places 200+ text, image, video, and audio models under one key and balance. Compare the same brief across Nano Banana 2, Seedream 5.0 Pro, or GPT Image 1.5 without maintaining separate provider credit pools.
Use the request format in the fixed API Usage section. The current GPTProto rate is $0.02016 per 1K generation; check the live panel before estimating a production budget.
