Geometric Composition
Text-to-Image“A glass cube on a wooden table. Inside the cube is a small blue sphere. On top of the cube sits a red book. A green plant is behind the cube, partially visible through the glass. Soft window light from the left.”
AI Judge Analysis
FLUX.2 [flex]
- + Perfect adherence to the prompt's spatial instructions.
- + Excellent glass refraction and realistic material textures.
- + Clean, high-resolution composition with natural soft lighting.
Nano Banana
- + Beautiful cinematic lighting with visible dust motes.
- + Realistic wood grain texture on the table.
- − Physics error where the blue sphere is floating unnaturally in the center of the cube.
