Complete guide to using Nano Banana 2 Lite
Access Nano Banana 2 Lite API on ApiPass for low-latency 1K image generation, prompt-based image editing, and scalable creative production. Build fast text-to-image and image-to-image workflows with the ApiPass model google/nano-banana-2-lite.
Nano Banana 2 Lite, also known as Gemini 3.1 Flash-Lite Image, is a speed-focused image model from Google DeepMind. It is designed for fast visual drafting, efficient creative iteration, high-volume 1K image creation, and responsive image output in product-facing scenarios. With Nano Banana 2 Lite API on ApiPass, developers can add fast text-to-image generation and practical prompt-based image editing to apps, creative tools, e-commerce workflows, marketing systems, and user-facing visual products.
Nano Banana 2 Lite API turns natural language prompts into images for visual drafts, marketing concepts, product scenes, social media assets, thumbnails, and app-based creative outputs. By defining the subject, scene, style, composition, lighting, and intended use, developers can quickly test multiple creative directions.
Provide image URLs and editing instructions to refine an existing visual instead of starting from scratch. The API can support use cases such as changing backgrounds, adjusting objects, updating styles, improving composition, or polishing generated images for lightweight creative workflows.
Nano Banana 2 Lite is optimized for fast 1K image output, making it suitable for rapid prompt testing, interactive design tools, in-app visual generation, product previews, and frequent creative requests where responsiveness and efficiency matter.
Nano Banana 2 Lite API provides 1K image output for app visuals, social media graphics, product concepts, thumbnails, creative drafts, and lightweight marketing assets. It is a practical choice when teams need clear visual results quickly without using heavier production models for every request.
Speed is one of the main advantages of Nano Banana 2 Lite API. It is suitable for rapid prompt testing, interactive design tools, visual ideation, creator apps, and user-facing image generation features where users expect a responsive creative experience.
When image generation becomes a frequent product action, Nano Banana 2 Lite gives developers an efficient option for repeated creative requests and scalable visual production, including product visuals, social media assets, marketing variations, and in-app generated images.
Although Nano Banana 2 Lite is built for speed and efficiency, it still supports useful prompt adherence, character consistency, prompt-based editing, readable visual composition, and real-world visual knowledge for creative tools, e-commerce visuals, marketing systems, and lightweight branded image generation.
Design platforms can use Nano Banana 2 Lite API to generate visual ideas directly inside a creative canvas. Users can create hero image drafts, interface illustrations, sticker concepts, mood-board elements, and background visuals while staying inside a drag-and-drop or node-based editor.
Travel, lifestyle, and entertainment apps can use Nano Banana 2 Lite to turn a prompt, user photo, avatar, or character reference into location-themed postcard images, such as a character near the Eiffel Tower, walking through Kyoto at night, or appearing in a vintage road-trip card.
Interactive games and story apps can create fast 1K scene cards, item visuals, location images, and character moments based on player actions. This helps role-playing games, voice-controlled games, and interactive fiction products feel more dynamic.
AI agent products can generate supporting visuals for slide decks, landing pages, blog drafts, reports, and web page sections. Agents can create section banners, concept illustrations, product mockups, and decorative images that make generated content feel more complete.
Seller tools can turn product descriptions or simple product images into lifestyle scene drafts, helping merchants test product positioning, seasonal campaign directions, and marketplace thumbnail ideas before final commercial production.
Creator platforms can let users edit images through natural language instructions, such as replacing backgrounds, removing distracting objects, adjusting lighting, changing visual style, or refining composition without professional retouching software.
Nano Banana 2 Lite is positioned as the faster and more efficiency-focused option in the Nano Banana image family. It is best suited for rapid visual drafting, prompt testing, 1K image generation, and frequent image creation workflows.
Nano Banana 2 Lite focuses on speed and efficient 1K image output, while Nano Banana 2 is designed for stronger overall image quality and broader resolution flexibility. Choose Nano Banana 2 Lite when fast drafts, app visuals, and frequent creative generation matter most; choose Nano Banana 2 when higher-resolution output and stronger visual detail are required.
Nano Banana 2 Lite is optimized for responsive generation and lightweight editing. Nano Banana Pro is better suited for complex, production-oriented creative control, brand-sensitive visuals, accurate text rendering, localization, and detailed scene logic where precision is more important than speed.
Earlier Nano Banana models can still support general 1K image generation, but Nano Banana 2 Lite is designed as a faster and more efficient option for modern product workflows that require responsive visual output and frequent generation.
Nano Banana 2 Lite API is suitable for teams that need fast 1K image generation, frequent prompt testing, creative previews, and lightweight image editing without relying on heavier production models for every request.
ApiPass documentation helps developers understand authentication, request structure, prompt input, image URL handling, response polling, callback behavior, and deployment details. The Create Task endpoint returns a taskId, and results are available through the Query Task endpoint or callback notifications.
ApiPass supports provider routing through the channel parameter. Use auto for automatic allocation, or choose starter, regular, or official depending on your quota, stability, cost, and execution requirements.
Submit generation requests with POST /api/v1/jobs/createTask, then query status with GET /api/v1/jobs/recordInfo. Task states include waiting, queuing, generating, success, and fail. Successful tasks return generated image URLs in resultJson.resultUrls.
Create an ApiPass account or sign in to your existing account, then open the API dashboard to generate your API key. Use this key with the Authorization: Bearer YOUR_API_KEY header when connecting Nano Banana 2 Lite API to your product, backend service, or internal creative tool.
Before deployment, use the ApiPass Playground to test text-to-image prompts, image editing instructions, different visual styles, product scenes, social graphics, and app-ready image drafts. Playground testing helps you understand how the model responds before writing production logic.
Prepare your Create Task request with model google/nano-banana-2-lite and an input object containing prompt, optional image_urls, and aspect_ratio. The prompt is required and supports up to 20000 characters; image_urls supports up to 10 JPEG, PNG, or WEBP image URLs up to 30MB each.
Send requests to POST https://api.apipass.dev/api/v1/jobs/createTask. The API returns a taskId. Query GET https://api.apipass.dev/api/v1/jobs/recordInfo?taskId=YOUR_TASK_ID until the state is success or fail, or provide callBackUrl to receive completion notifications automatically.
Once deployed, review generated images for prompt accuracy, visual quality, text rendering, character consistency, and user experience. Track usage patterns, optimize prompts, refine request logic, and keep your integration aligned with the latest ApiPass API documentation.
All APIs require authentication via Bearer Token.
Authorization: Bearer
Submit a new Google Nano Banana 2 Lite text-to-image or image-to-image task.
The API accepts a JSON payload with model and input at the root level. callBackUrl and channel are optional root-level fields.
