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
1:1,3:2,2:3,3:4,4:3,4:5,5:4,9:16,16:9,21:9aspect ratios. - Supported
image_sizevalues:1024px(1K). (Note: 2K and 4K are unsupported). - SynthID watermarking (Always On) + C2PA.
