Describe What You Want
Type a natural-language prompt. You can be specific ("a corgi wearing aviator sunglasses, studio lighting, shallow depth of field") or loose ("a cozy autumn coffee shop"). Seedream 5 understands both. Upload reference images if you want to lock a character's face, a brand style, or a product. Structured prompts help, but aren't required — the model fills in sensible defaults.

Seedream 5 Reasons Through Composition
This is what's new in Seedream 5: chain-of-thought reasoning. Instead of generating pixels greedily, the model first plans composition, lighting, color palette, and subject placement — then generates. It can pull in real-time web search for current references (events, products, locations) rather than relying on stale training data. You see progress stream via SSE as the image builds.

Edit, Iterate, Download
Not perfect on the first try? Use plain-English edits ("make the sky warmer," "remove the lamp," "give her a red jacket"). Or use precision editing to change one element while keeping the rest. When ready, download your finished image. Need maximum resolution? Seedream 4.5 outputs native 4K — 3840×3840, 3840×2160, or 2160×3840. All outputs include commercial-use rights.
5 Pro Tips
Start broad, then refine. One vague prompt + three targeted edits beats one overly-engineered prompt.
Reference images lock identity. Upload up to 10 reference images for a character — Seedream 5 keeps the face consistent across completely different scenes.
Text prompts that read as sentences beat keyword lists. "A woman laughing in a sunlit kitchen" outperforms "woman, laughing, kitchen, sunny, portrait."
Use 1:1 for social, 16:9 for hero images, 9:16 for vertical video thumbnails. Choose early — switching aspect ratio mid-iteration burns credits.
When in doubt, ask Seedream to "think about the composition" in the prompt itself. Chain-of-thought reasoning triggers on cues like "plan the shot" or "arrange the scene thoughtfully."
常见问题
不需要。Seedream 5 的链式推理会为简短提示填入合理的默认值。详细提示给您更多控制，但简短提示适用于大多数创意探索。
这取决于模型。Seedream 5 Pro 最高渲染 2720×1530，Seedream 5 Lite 最高 3072px，Seedream 4.5 输出原生 4K，支持三种比例：3840×3840（1:1 正方形）、3840×2160（16:9 横向）、2160×3840（9:16 纵向）。无需放大 — 开箱即可打印。
可以。用自然语言描述编辑（"将夹克改为红色"），或使用精确编辑来更改一个元素同时保留其余部分。编辑消耗的积分与新生成相同。
