Seedream 常見問題

What is the maximum output resolution?

文生圖最高支援 4K 解析度。圖片編輯可在 v4 上選擇 1K、2K 或 4K 輸出。

How accurate is text rendering in Seedream?

Seedream has strong typography support — it reliably renders text like headlines, logos, and labels within generated images, especially in v4.5 and v5.

What is the difference between text-to-image and edit modes?

文生圖從零開始生成。編輯模式接受一張或多張來源圖片加上文字指令,進行有針對性的指令引導編輯,同時保留圖片其餘部分。

Does Seedream 5 Lite use web search?

Yes — Seedream 5 Lite can perform real-time web search for time-sensitive prompts, generating images informed by current events and trends.

How fast is generation?

Seedream 4.5 generates in a few seconds. Seedream 5 Lite is faster and ~15% cheaper.

我應該先從哪個版本開始?

先選擇符合你品質標準中最便宜的版本。大多數團隊會先用快速版本,之後再升級到專業版用於正式上線。
