**Nano Banana 2 Lite** is designed as the efficiency specialist of the image generation family, offering ultra-low latency and cost-effective image generation and editing. By targeting a sub-2 second latency and significantly reduced TPU compute costs, this model enables high-volume interactive developer use cases and real-time consumer applications. **Key capabilities:** - **Sub-2 second end-to-end latency** - **Interleaved generation and editing** with native support for Text -\> Text + Image(s) and Image + Text -\> Text + Image(s). - **Optimized for lower resolutions** of 1K (1024x1024px). - Supports a discrete set of **14 aspect ratios** including standard formats. - **Fast multi-turn local edits** (swapping colors, sticker creation, background adjustments). - Maintains high character alignment matching original Nano Banana standards. - New `1:1`, `3:2`, `2:3`, `3:4`, `4:3`, `4:5`, `5:4`, `9:16`, `16:9`, `21:9` aspect ratios. - Supported `image_size` values: `1024px` (1K). *(Note: 2K and 4K are unsupported).* - **SynthID watermarking (Always On) + C2PA**.
