How to evaluate Seedream 4

A practical decision guide based on Magic Hour's current product support and the questions creators ask when comparing models.

Best fit on Magic Hour

Detailed image generation and editing when you need strong visual composition and a flexible general-purpose workflow.

Consider another model when

Use a newer Seedream model when multi-image consistency or the highest-detail final output matters more than draft cost.

Three useful first-run tests

Use the prompts below to test the failure modes that matter before committing to a larger batch.

Complex composition

“Editorial photograph of a glassmaker at work, furnace on the left, glowing vase centered, two assistants softly visible behind.”

Check subject count, spatial relationships, hands, tools, lighting, and unwanted duplicated objects.

Style-preserving edit

“Change the afternoon scene to blue hour while preserving the architecture, camera position, people, and painted illustration style.”

Check layout preservation, coherent relighting, color spill, and style consistency.

Text and product detail

“Create a premium tea tin labeled "JASMINE No. 8" with small text "SPRING HARVEST" beneath it.”

Check exact text, container geometry, material detail, and whether the label looks attached to the object.

These prompts are evaluation recipes, not controlled benchmark results. Run the same prompt and settings across models before drawing a conclusion.
