This is a simplified guide to an AI model called Flux-Krea-Dev maintained by Black-Forest-Labs. If you like these kinds of analysis, you should join AImodels.fyi or follow us on Twitter.

Model overview

The flux-krea-dev model represents a collaboration between Black Forest Labs and Krea, delivering an opinionated approach to text-to-image generation that prioritizes photorealism. This model distinguishes itself from other AI image generators by producing images that avoid the oversaturated, artificial appearance common in many AI-generated outputs. Unlike the speed-focused flux-schnell or the premium flux-pro, this variant emphasizes natural-looking results that could pass for traditional photography.

Model inputs and outputs

The model accepts text prompts and various configuration parameters to generate high-quality images. Users can control aspects like image dimensions, generation steps, and output quality while optionally providing reference images for image-to-image transformations.

Inputs

prompt: Text description for the desired image
aspect_ratio: Output dimensions from square to ultrawide formats (1:1, 16:9, 21:9, etc.)
image: Optional input image for image-to-image generation
num_inference_steps: Denoising steps (28-50 recommended range)
guidance: Control over prompt adherence (0-10 scale)
megapixels: Resolution selection (0.25 or 1 megapixel options)
go_fast: Toggle for fp8 quantization optimization
seed: Random seed for reproducible results
