•required 88 / 50000

Text instructions used to generate an image.

default auto

Choose the generated image's aspect ratio explicitly, including extreme options 4:1, 1:4, 8:1, 1:8, or select "auto" for a prompt-based choice by the model.

num_images default 1

Image count requested for generation.

Advanced system_prompt · output_format · safety_tolerance · thinking_level · seed · limit_generations
0 / 50000

Optional request-wide persona and output-style guidance, delivered to Gemini as a system instruction or to OpenAI-compatible providers as a system message. Nothing is sent for this instruction when the value is blank.

output_format default png

File format for the resulting image.

safety_tolerance default 4

Set content-moderation tolerance between the least restrictive level, 6, and the strictest level, 1, which blocks most content.

thinking_level

Select 'minimal' or 'high' to activate model thinking at that level and include its thoughts in the generation; leaving the level unset keeps thinking disabled.

Seed value that initializes random-number generation.

About Nano Banana 2 Lite

Generates 1 to 4 images from a `prompt` of up to 50000 characters. `aspect_ratio` supports many options including extreme 4:1, 1:4, 8:1 and 1:8, or auto. Output can be png, jpeg or webp. A `system_prompt` can steer style, and `thinking_level` can enable minimal or high thinking.

Parameters

Send either the canonical name or the native name, not both. Canonical names
