Parameter Reference

Required Supported Not available

Core Parameters

Parameter	Type	Description	Modes
`prompt`	string	Required. Text prompt for image generation	T2I Edit
`seed`	integer	Random seed for reproducibility	T2I Edit

Size & Layout

Parameter	Type	Description	Modes
`size`	string	Image dimensions as WxH pixels (e.g. "1024x1024") or aspect ratio (e.g. "16:9") WxH determines both shape and scale (aspect_ratio and resolution are ignored when size is provided). W:H format is equivalent to aspect_ratio.	T2I Edit
`aspect_ratio`	string	Aspect ratio of the output image (e.g. "16:9", "1:1") Controls shape independently of scale. Use with resolution to control both. If size is also provided, size takes precedence. Any ratio is accepted and mapped to the nearest supported value.	T2I Edit
`resolution`	string	Output resolution tier (e.g. "1K", "4K") `auto` `0.5K` `1K` `2K` `4K` Controls scale independently of shape. Higher tiers produce larger images and cost more. If size is also provided, size takes precedence for scale. Any tier is accepted and mapped to the nearest supported value.	T2I Edit

Output	`size`		`aspect_ratio` + `resolution`

How these parameters work

size

Exact pixel dimensions

"1920x1080"

aspect_ratio

Shape only, default scale

"16:9"

resolution

Scale tier, preserves shape

"1K"

Priority when combined

size › aspect_ratio + resolution › aspect_ratio › resolution

size is most specific and always wins. aspect_ratio and resolution control shape and scale independently.

How matching works

Shape matching – we pick the closest supported ratio. Ask for 7:1 on a model with 4:1 and 8:1, you get 8:1.

Scale matching – providers use different tier formats: K tiers (0.5K 1K 2K 4K) or megapixel tiers (0.25 1). If the exact tier isn't available, you get the nearest one.

Dimension clamping – if a model has pixel limits, we clamp dimensions to fit and keep the aspect ratio intact.

Media Inputs

Parameter	Type	Description	Modes
`image`	file	Required. Input image(s) to edit Supports PNG, JPEG, WebP. Up to 14 images per request.	T2I Edit

Output & Format

Parameter	Type	Description	Modes
`response_format`	string	How to return the image `url` `b64_json` Default: `"url"`	T2I Edit
`output_format`	string	Output image format `png` `jpeg` `gif` `webp` `avif` Gateway converts to requested format if provider doesn't support it natively.	T2I Edit
`output_compression`	integer	Compression level for lossy formats (JPEG, WebP, AVIF)	T2I Edit
`n`	integer	Number of images to generate Default: `1` Gateway generates multiple images in parallel even if provider only supports 1.	T2I Edit

Additional Parameters

Provider-specific passthrough fields, available only when the request is routed to the listed provider.

Parameter	Type	Description	Modes
Universal
`thinking`	string	Model's internal reasoning effort (off, on, minimal, high) `high` `minimal` `off` `on`	T2I Edit
fal
`enable_web_search`	boolean	Enable web search for the image generation task. This will allow the model to use the latest information from the web to generate the image.	T2I Edit
`limit_generations`	boolean	Experimental parameter to limit the number of generations from each round of prompting to 1. Set to `True` to to disregard any instructions in the prompt regarding the number of images to generate and ignore any intermediate images generated by the model. This may affect generation quality.	T2I Edit
`safety_tolerance`	string	The safety tolerance level for content moderation. 1 is the most strict (blocks most content), 6 is the least strict. `1` `2` `3` `4` `5` `6`	T2I Edit
`sync_mode`	boolean	If `True`, the media will be returned as a data URI and the output data won't be available in the request history.	T2I Edit
replicate
`google_search`	boolean	Use Google Web Search grounding to generate images based on real-time information (e.g. weather, sports scores, recent events).	T2I Edit
`image_search`	boolean	Use Google Image Search grounding to find web images as visual context for generation. When enabled, web search is also used automatically.	T2I Edit

Parameter Normalization

How we handle parameters across different providers

Not every provider speaks the same language. When you send a parameter, we handle it in one of four ways depending on what the model supports:

Behavior	What happens	Example
`passthrough`	Sent as-is to the provider	style, quality
`renamed`	Same value, mapped to the field name the provider expects	prompt
`converted`	Transformed to the provider's native format	size
`emulated`	Works even if the provider has no concept of it	n, response_format

Parameters we don't recognize pass straight through to the upstream API, so provider-specific options still work.

Prompt

“A candid street photo of an elderly Japanese man repairing a red bicycle in light rain, reflections on wet pavement, shallow depth of field, 50mm lens, natural skin texture, imperfect framing, motion blur from passing cars, cinematic but realistic, no stylization.”

The Capybara Taxi Driver

24 models

Text-to-Image

Prompt

“Photorealistic scene inside a yellow New York taxi at night. A capybara is driving, wearing a yellow taxi driver cap and a dark jacket. It has a calm, professional expression and both front paws on the steering wheel. In the back seat sits a human businesswoman in a coat, looking at her phone with a completely normal, bored expression (as if this is just another normal ride). Through the windows you can see the streets of Manhattan at night with blurred lights. Realistic taxi interior, photorealistic, detailed fur and fabric, 35mm lens, night lighting with reflections, shallow depth of field.”

Overview

Nano Banana 2 (slug: gemini-3.1-flash-image-preview) is a high-efficiency multimodal model developed by Google that bridges the gap between reasoning and visual synthesis. As the streamlined counterpart to the Gemini 3 Pro Image, it provides a unified interface for complex text generation and fast image creation. It is distinctive for its “Thinking Mode,” allowing the model to perform internal reasoning cycles before generating an image or structured text response.

Strengths

High-Efficiency Generation: Optimized for speed and low latency, making it suitable for real-time applications where rapid image iteration is required.
Complex Text Rendering: Excels at incorporating legible, accurate typography within generated images, a common failure point for many diffusion-based models.
Deep Reasoning Integration: Features a native thinking mode that allows the model to process complex prompts, spatial relationships, and logical constraints before producing visual or textual output.
Grounding and Tool Use: Supports search grounding and code execution, enabling the model to verify facts or perform calculations prior to generating content.
Reference Image Support: Capable of using existing images as structural or stylistic guides to maintain consistency across generated assets.

Limitations

Efficiency vs. Fidelity: While fast, it may lack the extreme aesthetic refinement and intricate textural detail found in the larger Gemini 3 Pro Image model.
Preview Status: As a preview release, the model may exhibit occasional inconsistencies in following highly nuanced stylistic prompts compared to more mature, production-stable versions.
Context Overhead: The use of internal reasoning (Thinking Mode) can increase processing time for simple tasks where a direct generation would have sufficed.

Technical Background

Part of the Gemini 3.1 Flash family, this model utilizes a multimodal transformer architecture trained for both discriminative and generative tasks. It integrates a latent diffusion-based image generation head directly into the language model pipeline, allowing for seamless transitions between modalities. By employing a “distilled” training approach, Google has optimized the model for high throughput while retaining the core reasoning capabilities of the Gemini 3.1 architecture.

Best For

Nano Banana 2 is ideal for building interactive design tools, rapid prototyping of social media assets, and automated content pipelines where both text and imagery are required. Its support for structured output and JSON mode makes it an excellent choice for developers needing to programmatically control visual attributes. You can experiment with these multimodal features and integrate them into your workflow through Lumenfall’s unified API and playground.
