SeedDream 4 on VM0. The photoreal text-to-image default
ByteDance's SeedDream 4 text-to-image model. Strong photoreal aesthetic at a cost comparable to the cheapest options in the lineup.
Image / Text-to-image
SeedDream 4 is ByteDance's text-to-image model in the Seedream V4 generation. Its standout property is the photoreal aesthetic — portraits, product shots, lifestyle photography — at a list price ($0.036 per image) that's competitive with the cheapest option in the curated lineup.
It's the natural default when the brief is specifically a photo. For stylised illustration or editorial design pick GPT Image 1 or Flux Pro 1.1 Ultra.
What is SeedDream 4?
April 2026 · ByteDance's photoreal text-to-image default in the Seedream V4 generation.
SeedDream 4 is the fourth generation of ByteDance's text-to-image family. The aesthetic skews towards photoreal output, with portrait, product and lifestyle shots as the standout categories. Prompt adherence on standard descriptive briefs (subject, setting, lighting) is solid.
At $0.036 per image it sits near the bottom of the curated lineup on price, which is what makes it viable as the default for photo-leaning agent workloads. Switch to Flux Pro 1.1 Ultra when the compositional brief is specifically a hero shot that justifies the premium.

How SeedDream 4 behaves in practice
Observed behaviour from production agent runs.
Photoreal aesthetic
Portraits, product shots and lifestyle photography are the standout categories. Output is competitive with Flux Pro 1.1 Ultra on a meaningful share of photoreal briefs and dramatically cheaper per call.
Cost
$0.036 per image — near the bottom of the curated lineup. The natural default for photo-leaning fan-out workloads.
Chinese-language prompts
Strong handling of Chinese-language prompts and culturally-anchored subjects, which is a real advantage for agents serving Chinese-speaking users.
Aesthetic ceiling
Solid for everything in the photoreal lane; less of a fit for hyper-stylised illustration where GPT Image 1 leads.
Best agent tasks for SeedDream 4
The portrait or product-shot agent at scale
Photoreal subjects at a low per-image cost make SeedDream 4 viable for fan-out workloads — a hundred product photos for a catalogue, batch portrait generation for a creator tool.

Strong handling of Chinese prompts and culturally-anchored subjects. The right default for agents serving Chinese-speaking markets.
The cheaper alternative to Flux Pro 1.1 Ultra

When to skip SeedDream 4
Skip SeedDream 4 for stylised illustration (GPT Image 1 leads) or hero-shot editorial work where the Flux premium is justified.
