Nano Banana 2 Lite

Google's fastest, most cost-efficient Nano Banana image model, built for high-volume 1K generation.

POST /v2/images/generate — model: "nano-banana-2-lite"

Google's fastest and cheapest Nano Banana model, built on Gemini 3.1 Flash Lite Image. It delivers text-to-image outputs in roughly 4 seconds while keeping the character consistency and text rendering of the Nano Banana family. Outputs are generated at 1K resolution across 14 aspect ratios, making it ideal for prototyping, real-time apps, and high-volume workflows at scale.

See Image Generation overview for common request fields, response format, and error codes.

Model-specific parameters

Parameter	Type	Description
`nanoBananaParams.aspect_ratio`	string	`"match_input_image"` or `"W:H"` format (e.g. `"16:9"`)
`nanoBananaParams.output_format`	string	`"jpg"` (default) or `"png"`
`nanoBananaParams.image_input`	string[]	Up to 14 reference image URLs
`nanoBananaParams.google_search`	boolean	Use Google Web Search grounding for real-time information
`nanoBananaParams.image_search`	boolean	Use Google Image Search for visual context

Nano Banana 2 Lite generates at 1K resolution only — there is no resolution parameter.

Credit cost

7 credits per generation.
