Seedream 5.0 Flashvs.Kandinsky-5.0-T2I-Lite-Pretrain

Which one is better?

In our own test, Seedream 5.0 Flash leads. Neither is in the arena. Neither has an API price.

Test images

Same task, the first image of each. The task with the biggest difference is preselected.

Seedream 5.0 Flash: Infographic, first image from the fixed test run — Seedream 5.0 Flash86 out of 100

Kandinsky-5.0-T2I-Lite-Pretrain: Infographic, first image from the fixed test run — Kandinsky-5.0-T2I-Lite-Pretrain23 out of 100

Result for “Infographic”:Seedream 5.0 Flash ahead

Prompt given to both modelsCreate a square German infographic titled SO FUNKTIONIERT PHOTOSYNTHESE. Show exactly four numbered steps in this order: 1 LICHT, 2 WASSER, 3 CO₂, 4 ZUCKER + SAUERSTOFF. Use a clean editorial science style with one plant cross-section, simple arrows, high contrast, legible labels, and no other text.

What the rating looks at: Numbers, labels, and visual organization.

“Ahead”: better in all three rating rounds. “Slightly ahead”: a higher value, but not in every round.

Test protocol of the images

Each test attempt uses the same archived prompt and one request. The first output of that attempt counts. Repeats after technical test failures are disclosed for the affected images. Files are normalized to 1,024 × 1,024 pixels without cropping. Provider resolution, randomness, quality tier and prompt processing can still differ. The images are a practical visual test, not a reconstruction of the arena configuration.
