Parameter Reference

Required Supported Not available

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.	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.	Edit
`resolution`	string	Output resolution tier (e.g. "1K", "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.	Edit

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.	Edit

Output & Format

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

Riverflow 1 Pro is an advanced image-to-image and text-to-image model developed by Sourceful, specifically engineered for high-fidelity professional editing workflows. As the flagship variant in the Riverflow 1 family, it prioritizes output precision and structural integrity over raw generation speed. The model is designed to handle complex manipulations where maintaining the core identity of an input image is as critical as the requested modifications.

Strengths

High-Fidelity Image Editing: Excels at “Pro” level transformations, such as changing specific textures or lighting conditions while preserving the geometry and composition of the original source image.
Text Rendering Accuracy: Demonstrates a high success rate in rendering legible, correctly spelled text within generated images compared to standard diffusion models.
Instruction Adherence: Closely follows nuanced prompts, allowing for granular control over artistic style, color grading, and object placement without significant “hallucination” or unwanted artifacts.
Structural Consistency: Maintains physical proportions and spatial relationships during complex re-rendering tasks, making it suitable for architectural visualization or product staging.

Limitations

Inference Latency: Due to the complexity and precision of the “Pro” variant, generation times may be longer than those of more lightweight or “Turbo” models in the Riverflow family.
Stylistic Rigidity: The model’s focus on precision can occasionally result in a more “clinical” or realistic aesthetic, which may require more descriptive prompting to achieve highly abstract or painterly results.

Technical Background

Riverflow 1 Pro is a latent diffusion model optimized for professional environmental and object manipulation. While it shares a common architecture with the Riverflow series, the Pro variant utilizes a larger parameter count and refined training datasets focused on high-resolution professional photography and design assets. This training approach emphasizes pixel-perfect reconstruction and fine-grained control over global and local image features.

Best For

Riverflow 1 Pro is ideal for professional design workflows, including product photography post-production, architectural overpainting, and high-quality character consistency tasks. It is an excellent choice for developers building creative tools that require predictable, high-caliber outputs rather than rapid-fire iteration.

Riverflow 1 Pro is available for immediate testing and deployment through Lumenfall’s unified API and playground, providing a streamlined way to integrate professional-grade image generation into your applications.
