Seedream 常見問題

What is the maximum output resolution?

文字生成圖像最高支援 4K 解像度。圖像編輯可以喺 v4 上輸出 1K、2K 或 4K。

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?

文字生成圖像係從零開始創建。編輯模式接受一張或多張來源圖片加上文字指令,進行有針對性嘅指令引導編輯,同時保留圖像嘅其餘部分。

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.

我應該先用邊個版本?

先選最平而且符合你質素要求的版本。大多數團隊會先用快速版本,之後再升級到 pro 用於正式生產。
