}'Kunavo 与直连 OpenAI 的区别
同一个 GPT-Image-2,同样的输出。网关改变的是账号、SDK 和账单——下面是如实对照。
| Kunavo | 直连 OpenAI | |
|---|---|---|
| 价格(per image) | $0.0633 (−50%) | $0.13 |
| 账号 | 一个 Kunavo 账号,2 分钟拿到 Key,最低充值 $10 | 需要 OpenAI 账号,并单独配置其计费 |
| SDK | 继续用 OpenAI SDK——改 base_url,model 填 "gpt-image-2" | OpenAI 官方 SDK,或其提供的 OpenAI 兼容层 |
| 同一个 Key 还能调用 | Claude、Gemini、GPT 以及图像、视频、音频模型 | 仅 OpenAI 自家模型 |
| 计费 | 一个 Stripe 余额,按量付费,余额不过期;失败请求不计费 | 每家厂商一张独立账单 |
| 速率限制 | 共享网关容量,无按账号的合约级限额 | OpenAI 自家档位限额,可凭用量或合约提升 |
如果你需要合约级速率限制、企业 SLA,或首日就要用上厂商独有功能,直连 OpenAI 更合适。如果你想要一个 Key、一张账单,并在所有厂商上拿到更低的单价,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.
