A futuristic robot with blue and red glowing neon lights kneels on a stone platform surrounded by large circular portals emitting warm orange light in a misty sci-fi environment.
Surreal painting of a dark exploded building with jagged edges illuminated by a vibrant sunburst, framed by orange autumn leaves against a blue sky with intricate shattered windows and eerie shadows.
Detailed cybernetic android with a retro-futuristic head and mechanical neck components, wearing an orange leather jacket, set against a blurred industrial background.
A dark, moody futuristic cityscape with towering buildings and light beams, featuring a silhouetted cyborg figure standing at the forefront, inspired by Moebius style.
Adorable small bear wearing a yellow waterproof raincoat stands on wet pavement in a rainy urban street, with water droplets on its fur and coat.
Hyper-detailed photo-realistic portrait of a woman whose skin resembles the surface of the moon, adorned with intricate black and white patterns, set in a haunting Japanese-inspired style with metallic headgear, evoking galactic peace and mystery.
Cadaverous boy with large black-rimmed eyes, alabaster skin, rictus grin, wearing a black top hat decorated with vines and dressed in a dark suit, in an eerie whimsical style.
Hyper-realistic biomechanical cyborg with a rusted yellow and black helmet showing corroded metal and organic alien tissue fused with mechanical parts.
A red bullet train crossing a large gleaming metal arch bridge supported by ring stanchions, with water below reflecting the structure and train.

Tips

Use dedicated SamplersCustomAdvanced node for FLUX for better integration.

Use FluxGuidance node between prompt and sampler for guidance management if not using dedicated FLUX sampler node.

Compact models reduce size by about 30% allowing usage on less powerful machines without quality loss.

Keep CFG at 1 on samplers and adjust guidance via FluxGuidance nodes (recommended Flux Guidance: 2+).

FLUX COMPACT

I am excited to present a collection of compact Flux models, with Clips and VAE included in a single model, optimized to integrate seamlessly into a variety of existing workflows. These compact versions come with the various combinations of Clips and Models, ensuring that they can be easily loaded directly via nodes such as 'CheckpointLoaderSimple' and others, without the need for additional configuration.

As Sampler Node you can use the ones already present for SDXL using CFG 1, or you can use 'SamplersCustomAdvanced' that is dedicated to FLUX.

If you use the dedicated FLUX node above , you can use one of the 'Guiders' as nodes to manage the guidance instead of the 'CFG of the sampler'

if not, you can use the 'FluxGuidance' node placed between the prompt and the sampler to manage the guidance on the other samplers already present for SDXL, keeping their CFG at 1 and modifying that of the new node.

By reducing the final size by about 30%, these models are also accessible on less powerful machines, although I am not sure how this is possible. In my tests, I have not observed any differences in the generated outputs compared to the full versions.

Let me know more with your experiments.

I claim no credit for the original creation and publication of these models; all rights are reserved to 'Black Forest Labs' and their talented team. My goal is to make their excellent work more accessible to the community.

I hope these compact Flux models will be useful to you and contribute to your creative and technical endeavors. Your feedback is greatly appreciated as we continue to explore and refine these tools together.
