}'Kunavo 與直連 ByteDance 的差異
同一個 Seedance 2.5，同樣的輸出。閘道改變的是帳號、SDK 與帳單——以下是如實對照。
| Kunavo | 直連 ByteDance | |
|---|---|---|
| 帳號 | 一個 Kunavo 帳號，2 分鐘取得 Key，最低儲值 $10 | 需要 ByteDance 帳號，並另外設定其計費 |
| SDK | 繼續用 OpenAI SDK——改 base_url，model 填 "seedance-2-5" | ByteDance 官方 SDK，或其提供的 OpenAI 相容層 |
| 同一把 Key 還能呼叫 | Claude、Gemini、GPT 以及影像、影片、音訊模型 | 僅 ByteDance 自家模型 |
| 計費 | 一個 Stripe 餘額，用多少付多少，餘額不過期；失敗請求不計費 | 每家廠商一張獨立帳單 |
| 速率限制 | 共享閘道容量，無帳號層級的合約限額 | ByteDance 自家級距限額，可依用量或合約調升 |
若你需要合約級速率限制、企業 SLA，或首日就要用到廠商獨有功能，直連 ByteDance 較合適。若你想要一把 Key、一張帳單涵蓋所有廠商，不必逐家開戶，就用 Kunavo。

The tradeoff is that gateway capacity is shared — if you need a contractual rate limit or an enterprise SLA on Seedance 2.5 specifically, go direct to ByteDance.
