}'Kunavo 與直連 Google 的差異
同一個 Veo 3.1 Fast，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 Google | |
|---|---|---|
| 價格（per video） | $0.36+ (−70%) | $1.20 |
| 帳號 | 一個 Kunavo 帳號，2 分鐘取得 Key，最低儲值 $10 | 需要 Google 帳號，並另外設定其計費 |
| SDK | 繼續用 OpenAI SDK——改 base_url，model 填 "veo-3" | Google 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 Google 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 | Google 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 Google 較合適。若你想要一把 Key、一張帳單，並在所有廠商上取得更低單價，就用 Kunavo。

What is different from calling Google directly?
The model is the same, at about 70% under Google's list price. What changes is around it: one key and one Stripe balance instead of a Google account with its own billing, the OpenAI SDK with base_url swapped instead of a provider-specific SDK, and the same key also reaching Claude, Gemini, GPT, image, video and audio models. The tradeoff is that gateway capacity is shared — if you need a contractual rate limit or an enterprise SLA on Veo 3.1 Fast specifically, go direct to Google.
