Seedream 4.5 vs Seedream 5 Lite
Generated on PixelDojo. Produced by PixelDojo's generation pipeline.
Seedream 4.5 and Seedream 5 Lite both cost 1 credit per image, so this comparison comes down to what each one actually produces. We edited the same character reference into the same rainy street scene with both on August 26, 2026. Seedream 5 Lite finished in about 36 seconds and wrote legible shop signs into the background. Seedream 4.5 also took about 36 seconds and attempted signage that came out as garbled, not-quite-words.

How It Works
How we ran the comparison:
Start from the same reference photo
One character sheet, generated earlier with a character-consistency tool, fed as the only reference to both models.
Send the same scene-placement instruction
One prompt naming every identity detail to preserve, with neon shop signage as part of the setting.
Zoom into the signage in both results
Since the prompt didn't specify exact sign text, we checked whether each model's attempt at lettering came out as real, readable words or as decorative gibberish.

| What we saw: Seedream 5 Lite | A 2848x1600 side-angle shot with a coffee shop and noodle stand behind the subject, and three separate signs rendered as clean, real, readable words: 'NOODLES', 'COFFEE', and 'OPEN'. |
