This example walks through training a style LoRA using a fully synthetic dataset β images generated with FLUX.1 [dev] and various illustrative LoRAs at different strengths.
The resulting style has painterly brushwork with strong graphic structure β bold shapes, deep shadows, saturated but limited colors. Edges go between soft and sharp, giving it a hand-painted feel.
Below 20 images: Insufficient variation for generalization
Above 40 images: Style dilution through excessive variation
Dataset composition should include diverse angles, subjects, and compositions to enable aesthetic generalization rather than scene memorization.This example uses: 27 training images with corresponding caption files.Training Dataset:
Captions should only describe whatβs in the image β no style descriptors. With a small dataset, the model strongly associates text with visuals. If you leave out style descriptions, itβs forced to learn the visual style implicitly from the images themselves.A unique trigger word (e.g. GFX_IMPR5N) in every caption gives you a way to activate the style at inference without polluting the base modelβs vocabulary.
Caption:GFX_IMPR5N. Close Up Three Quarter Left of a scorpion standing on a rounded rock surface. The scorpionβs body angles from the lower left toward the upper right, with both pincers extended forward and the segmented tail arched upward over the back ending in a stinger. Multiple legs are spread to either side, and the abdomen shows distinct segment divisions. The rock occupies the lower foreground, with the scorpion centered above it against an open background.Omitted descriptors: Solid black background, red highlight, painterly brushstrokes

The larger network (approximately 500MB per model) captures low-frequency details including subtle textures, color relationships, and tonal variations.Smaller dimension use cases:
Low detail content (e.g., 2D vector logos)
Content-focused training (compositions, high-noise characteristics)
Training objectives focused on high-noise elements
Smaller networks prevent interference with low-noise style characteristics. Film grain training exemplifies super low-noise processing, as grain exists at the granular pixel level. Such fine texture learning requires larger network dimensions for adequate capture.
Timestep Bias: shift
Encourages overfitting of low-frequency information. Textures and colors adopt more rudimentary characteristics, producing unpolished, sketch-like qualities.Learning Rate: 0.000095
Decreased from default value. Preserves broken, gestural linework from training data rather than applying smoothing.Weight Decay: 0.00015
Increased from default value. Simplifies shapes and colors, reducing compositional complexity and emphasizing bolder, cleaner forms.
The 1500-step checkpoint produced optimal results.Style-specific considerations: The loose, sketch-like aesthetic required reduced training duration. Higher step counts introduced excessive realism, compromising painterly spontaneity.Step count, configuration parameters, and target aesthetic form an interdependent system. No universal optimal configuration exists; effectiveness depends on specific training objectives.
Progressive training visualization: Base model only (left) β 6000 training steps (right)
Inference Steps: 8
Significantly reduced from typical ranges (20 to 50 steps). Aligns with reduced training duration to preserve soft, painterly, impressionistic qualities.
