FLUX LoRA (RealismLoRA) | Photorealistic Images

Workflow Name: RunComfy/FLUX-LoRA
Workflow ID: 0000...1116
Updated 6/16/2025: ComfyUI version updated to v0.3.39 for improved stability and compatibility. The ComfyUI FLUX-RealismLoRA workflow elevates AI image generation to new heights of photorealism. By combining the FLUX-1 text-to-image model with FLUX-RealismLoRA, trained on a curated dataset of high-resolution photographs and captions, this workflow enables the creation of incredibly lifelike images from text prompts alone. Experience the power of AI-generated realism without the need for complex prompts.

FLUX is a new image generation model developed by Black Forest Labs, The flux-RealismLora created by XLabs AI team, enhances its realism capabilities. This ComfyUI FLUX-RealismLoRA workflow was created by Leo Kadieff. All credit goes to their contribution.

What is the ComfyUI FLUX-RealismLoRA workflow?

The ComfyUI FLUX-RealismLoRA workflow combines the FLUX-1 text-to-image model with a FLUX-RealismLoRA model. The FLUX-RealismLoRA model has been trained on a dataset of realistic photos and prompts, enhancing FLUX-1's capability for photorealism.

By using this FLUX-RealismLoRA workflow, you can generate incredibly photorealistic images from text prompts alone, without the need to include numerous realism-related tokens in every prompt, such as "a RAW ultra-realistic photo, UHD, 8k".

About FLUX

The FLUX models are preloaded on RunComfy, named flux/flux-schnell and flux/flux-dev.

  • When launch a RunComfy Medium-Sized Machine: Select the checkpoint flux-schnell, fp8 and clip t5_xxl_fp8 to avoid out-of-memory issues.
  • When launch a RunComfy Large-Sized or Above Machine: Opt for a large checkpoint flux-dev, default and a high clip t5_xxl_fp16.

About FLUX-RealismLoRA

The FLUX-RealismLoRA is available on RunComfy as flux/realism_lora.safetensors.

Trained on a curated dataset of high-resolution photorealistic images with text captions, the FLUX-RealismLoRA weights guide the FLUX-1 model to generate images resembling real photographs by emphasizing:

  • Detailed sharpness
  • Realistic textures, shadows, and lighting
  • Believable proportions and perspectives
  • Natural color palettes and tones

This compact FLUX-RealismLoRA file (22MB) can be loaded into FLUX-1, enhancing photorealistic generation without altering the base model weights. It functions as a "realism filter," shaping the model's outputs.
