Parameter Reference

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.

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.

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.
