Pipeline-Specific Guidelines

🔹 Flux Dev

• Upload 10–20 images in a ZIP.

• Select a trigger_word → model learns to associate this word with your subject/style.

• Captions: Auto-generated or custom .txt per image.

  • Example: img_0.jpg → img_0.txt.

• Image resolution: ~1024×1024 (larger images will be resized).

• Style LoRAs: Use images highlighting distinctive features, keep style consistent.

• Character LoRAs: Show subject in different settings/expressions.

  • Avoid different haircuts, ages, or excessive hand-face overlaps.
