Seedream 4.5 vs Seedream V5 Lite: 6 prompt test
Seedream 4.5 and Seedream V5 Lite both target fast, high resolution image generation. This post runs the same six prompts through both models and compares typography, product lighting, crowded scenes, diagram style, portraits, and glass realism.

- Watermark: false
Results
Test 1: typography poster
Prompt: Minimalist poster on white background, big text WIRO, smaller text API MARKETPLACE, Swiss grid layout, clean typography, print texture

Both models place the layout cleanly. Small text still shows edge wobble on close zoom, but it stays closer to real letters than typical diffusion noise.
Test 2: product photo close-up
Prompt: Studio product photo of a stainless steel espresso machine knob with water droplets, softbox lighting, shallow depth of field, ultra sharp

Look for droplet shape consistency and highlight control. This prompt also reveals whether metal turns into plastic under heavy sharpening.
Test 3: crowded scene realism
Prompt: Open air bazaar in Istanbul at dusk, wet cobblestone street, hanging lanterns, crowded scene, cinematic lighting, detailed faces

Crowded scenes tend to break faces and hands first. A good output keeps readable silhouettes without turning the background into mush.
Test 4: diagram style with labels
Prompt: Isometric technical illustration of an API gateway connected to GPU servers and a database, labels GPU API DB, clean vector style, white background

Vector prompts are a trap. Even when the style lands, exact label text rarely stays perfect without a quick edit pass.
Test 5: portrait detail
Prompt: Ultra realistic portrait of a firefighter in a rain soaked jacket, soft rim light, detailed skin texture, 85mm lens look, neutral background

Portraits show whether skin turns waxy and whether eyes stay aligned. Jacket fabric and rain detail also reveal how the model handles fine noise patterns.
Test 6: glass and caustics (hard)
Prompt: Transparent glass perfume bottle on black slate, label text AURA, dramatic spotlights, realistic caustics, high detail, product photo

Glass still exposes fake physics fast. Refraction edges and label text usually break before lighting does.
