Kunavo 与直连 OpenAI 的区别

同一个 GPT-6 Astra，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 1M tokens）$4.00 / $20.00 (−60%)$10.00 / $50.00
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-6-astra"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-6 Astra cost?

On Kunavo, GPT-6 Astra is $4.00 per 1M input tokens and $20.00 per 1M output tokens — about 60% 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-6 Astra with the OpenAI SDK?

What is GPT-6 Astra good for?

GPT-6 Astra is a text model from OpenAI, with support for function, streaming, thinking, long-context.

What is different from calling OpenAI directly?

The model is the same, at about 60% 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-6 Astra specifically, go direct to OpenAI.

Is GPT-6 Astra cheaper on Kunavo?

Yes — GPT-6 Astra is about 60% 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.
