arch_sktechs_flux_lora_v1

This is a LyCORIS adapter derived from black-forest-labs/FLUX.1-dev.

The main validation prompt used during training was:

an architectural sketch of a modern architecture, concrete, two stories, gray, windows, urban landscape, cultural building, side view, geometric shape, clean lines, flat roof, minimalistic design, public space, large mass, dominant volume, no visible vegetation, straight edges, sleek facade

Validation settings

• CFG: 3.0
• CFG Rescale: 0.0
• Steps: 20
• Sampler: None
• Seed: 42
• Resolution: 1024x1024

Note: The validation settings are not necessarily the same as the training settings.
