Sam Francis

Custom FLUX.1-dev LoRA, fine-tuned on Sam Francis's own canvas work.

A LoRA (low-rank adaptation) is a compact set of trainable weights that sits on top of a much larger frozen base model. Instead of retraining FLUX.1-dev, the open-source 12-billion-parameter text-to-image transformer from Black Forest Labs, the LoRA only adjusts ~50 million new parameters using a small artist-specific dataset. The result keeps FLUX's general image-generation ability intact while teaching it one artist's visual language.

Pieces in this gallery are produced by a private FLUX.1-dev LoRA trained on 31 hand-curated reproductions from samfrancis.com, drawn from his Works on Canvas catalog (1946-1992), including oil and acrylic paintings across his action-painting and color-field periods. Every image was captioned with its title, medium, dimensions, and year, binding the trigger to specific painterly cues rather than a generic style label.

Trigger word sam_francis_style is prepended to every weather-derived prompt before inference. Trained 2026-05-05 via ostris/flux-dev-lora-trainer on Replicate.
