Same words, three tiers
Seedream 5 Flash against Lite and Pro, on a stopwatch
Pick a brief, then a tier. Each lane shows the measured run time for that exact image.
Mug, rag and brass parts all arrived, but five hex keys instead of six — one bent into an impossible U — and the derailleur became a toy-like sculpture of cogs. Right layout, simplified mechanism.
Output 2048 × 1536. Prompt: “Overhead flat lay of a bicycle mechanic workbench on scratched steel: a disassembled rear derailleur, a coiled chain with individual links, six hex keys fanned by size, a grease-stained cotton rag, brass spoke nipples in a tin lid, and a chipped enamel coffee mug, hard top light with short shadows, every small part sharp, editorial catalogue photography, no text”
Six runs, 60 credits
A Seedream 5 Flash draft sheet, reviewed
One product brief, six colour words. Colour followed the brief every time; the lamp did not — Seedream 5 Flash redesigned it on each run. Select a frame to read our call.
Lock the design, then recolour it
Generate once, then edit. Seedream 5 Flash kept the arm, joints, shade and shadow and changed only the colour, for another 10 credits. The edited terracotta came out deeper, so name the shade.
