Same prompt, real images — no cherry-picking
We ran each prompt once on both models at the entry tier (1K / Basic) and kept the first result. Here's exactly what came back.
Round 1 — Poster typography
The prompt: A retro travel poster with the headline "VISIT KYOTO" in large elegant serif type at the top and the tagline "Old streets, new stories" below it, a torii gate at sunset, warm oranges and deep reds, clean vintage print style
Both models spelled every word perfectly. Nano Banana Pro chose a flat vintage-print illustration; Seedream 5 Pro went photographic with type over a real scene. A style choice, not a quality gap.
Round 2 — Photoreal portrait
The prompt: A photorealistic close-up portrait of an elderly fisherman with weathered skin and a gray beard, golden hour light on his face, shallow depth of field, visible skin texture and fabric detail on his wool sweater
Both could pass for photos. Nano Banana Pro renders heavier skin texture and pore-level detail up close; Seedream 5 Pro leans into a warmer, more cinematic sunset look.
Round 3 — Busy market scene
The prompt: A busy Saturday farmers market from a slightly elevated angle: at least eight distinct stalls with fruit, flowers, bread, and cheese, dozens of people browsing, string lights overhead, every stall sign readable, rich detail everywhere
A surprise: Nano Banana Pro kept every stall sign crisp and readable, while Seedream 5 Pro packed in a larger crowd but let a couple of signs wobble. Dense scenes are closer than the spec sheet suggests.
Round 4 — Labeled infographic
The prompt: A product infographic for a smartwatch on a clean white background: the watch centered, four labeled callout lines pointing to the screen, strap, sensor, and button, each label short and readable, minimal tech aesthetic
Nano Banana Pro followed the four-callout plan to the letter. Seedream 5 Pro delivered a cleaner, more minimal layout with icon labels. Both readable — pick by taste.
