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` `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

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.	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

Parameter	Type	Description	Modes
`allow_fallback_model` replicate	boolean	Fallback to another model (currently bytedance/seedream-5) if Nano Banana Pro is at capacity.	T2I Edit
`enable_web_search` fal	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` fal	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.	T2I Edit
`safety_filter_level` replicate	string	block_low_and_above is strictest, block_medium_and_above blocks some prompts, block_only_high is most permissive but some prompts will still be blocked `block_low_and_above` `block_medium_and_above` `block_only_high`	T2I Edit
`safety_tolerance` fal	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` fal	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

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.

Overview

Gemini 3 Pro Image Preview is a multimodal model developed by Google that integrates advanced reasoning capabilities with native image generation and editing. Specifically designed to bridge the gap between complex cognitive tasks and visual synthesis, this model allows users to perform interleaved text-and-image workflows within a single session. It is distinctive for its high-density reasoning performance and its ability to process diverse inputs—including audio, video, and files—while outputting both descriptive text and high-fidelity images.

Strengths

Interleaved Reasoning and Synthesis: Unlike models that treat image generation as a separate tool, this model can reason about a prompt’s context and generate images that reflect complex logic or multi-step instructions.
Comprehensive Modality Support: The model accepts a wide array of input types, including video and audio, allowing for “visual-to-visual” workflows such as generating a static image based on a specific scene from a video file.
Structured Output and Tool Use: It excels at generating valid JSON schemas and executing function calls, making it highly effective for automation pipelines where image generation must be triggered by specific data conditions.
Long-Context Reasoning: Inheriting the Gemini family’s strength in context window management, it can maintain consistency across large amounts of input data before producing a visual or textual response.

Limitations

Preview Stability: As a “Preview” release, the model may exhibit inconsistencies in image composition or adherence to highly granular spatial constraints compared to specialized, single-purpose diffusion models.
Output Latency: Due to the computational overhead of combined reasoning and image synthesis, response times may be higher than text-only or small-scale generative models.
Specialized Artistic Control: While capable of high-quality generation, it may lack some of the fine-grained aesthetic control (such as specific seed-based styling or LoRA support) found in dedicated image generation frameworks.

Technical Background

Gemini 3 Pro is built on a transformer-based multimodal architecture designed for native cross-modal understanding. Rather than using a separate text-to-image “wrapper,” the model leverages integrated training objectives that allow visual and textual tokens to be processed in a unified latent space. Key technical features include a “thinking” mode for enhanced chain-of-thought processing and built-in code execution for validating logic before generating final outputs.

Best For

This model is ideal for building sophisticated creative assistants that require deep context, such as storyboard generators that analyze scripts (text or PDF) to create visual frames, or marketing tools that generate ad copy and matching imagery simultaneously. It is also well-suited for developers needing structured data extraction from images coupled with automated visual editing.

Gemini 3 Pro Image Preview is available through Lumenfall’s unified API and playground, allowing for easy integration into existing multimodal applications.
