./scripts/generate.py --prompt "A serene mountain landscape at sunset" --output images/landscape.png
With reference image for style guidance
./scripts/generate.py --prompt "Same character but wearing a party hat" --reference images/character.png --output images/party.png
Different output size
./scripts/generate.py --prompt "Abstract art" --output art.png --size 2K
