無縫相容 OpenAI SDK

把 OpenAI SDK 的 base_url 指向 api.kunavo.com/v1，換 model id 即可。流式、工具呼叫、SDK 行為完全一致。

在 /app/keys 建立 API key，複製為 KUNAVO_API_KEY，然後任選下面一段程式碼執行。

curl
curl https://api.kunavo.com/v1/images/generations \
  -H "Authorization: Bearer $KUNAVO_API_KEY" \
  -H "Content-Type: application/json" \

    "size": "1024x1024"
  }'

Kunavo 與直連 OpenAI 的差異

同一個 GPT-Image-2，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 OpenAI
價格（per image）$0.0633 (−50%)$0.13
帳號一個 Kunavo 帳號，2 分鐘取得 Key，最低儲值 $10需要 OpenAI 帳號，並另外設定其計費
SDK繼續用 OpenAI SDK——改 base_url，model 填 "gpt-image-2"OpenAI 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 OpenAI 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OpenAI 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 OpenAI 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。

FAQ

How much does GPT-Image-2 cost?

On Kunavo, GPT-Image-2 is $0.0633 per image — about 50% under OpenAI's official price. Failed requests are never billed, and it's pay-as-you-go — you only pay for successful calls.

Can I call GPT-Image-2 with the OpenAI SDK?

Yes. Set base_url to https://api.kunavo.com/v1, pass your Kunavo key, and set model to "gpt-image-2". Requests and responses are OpenAI-compatible.

What endpoint does GPT-Image-2 use?

GPT-Image-2 is called via POST /v1/images/generations on Kunavo's OpenAI-compatible API.

What is GPT-Image-2 good for?

GPT-Image-2 is a image model from OpenAI, with support for text-to-image.

What is different from calling OpenAI directly?

The model is the same, at about 50% under OpenAI's list price. What changes is around it: one key and one Stripe balance instead of a OpenAI 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 GPT-Image-2 specifically, go direct to OpenAI.

Is GPT-Image-2 cheaper on Kunavo?

Yes — GPT-Image-2 is about 50% under OpenAI's official list price on Kunavo, with no subscription and no minimum monthly spend. You pay per token from a $10 top-up, failed requests are never billed, and the balance never expires.
