Switch to Gemini 3.1 Flash-Lite for Ultra-Low Latency Image Generation
Use Gemini 3.1 Flash-Lite Image for fast, cheap visual assets.
Switch to the gemini-3.1-flash-lite-image model for high-speed, cost-effective image generation and conversational editing in high-volume environments.
The Scenario
A developer needs to generate thousands of dynamic product thumbnails or UI placeholders quickly and cheaply for a web application.
Before & after
Previously, developers relied on heavier Imagen models or manual editing, which could take 5–10 minutes per asset and incur higher compute costs.
Using Gemini 3.1 Flash-Lite Image, you can generate or edit assets via API in under 5 seconds, significantly reducing the cost per image.
The Prompt
I need to generate a low-cost, high-speed visual for a flash sale banner. Using the gemini-3.1-flash-lite-image model, create an image based on this description: [DESCRIBE_IMAGE_TOPIC_HERE]. Focus on high-speed rendering requirements.
The new Gemini 3.1 Flash-Lite Image (Nano Banana 2 Lite) is generally available and optimized for low-latency, high-volume image tasks.
