}'Kunavo 与直连 ByteDance 的区别
同一个 Seedance 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 ByteDance | |
|---|---|---|
| 账号 | 一个 Kunavo 账号，2 分钟拿到 Key，最低充值 $10 | 需要 ByteDance 账号，并单独配置其计费 |
| SDK | 继续用 OpenAI SDK——改 base_url，model 填 "seedance-2" | ByteDance 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 ByteDance 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 | ByteDance 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 ByteDance 更合适。如果你想要一个 Key、一张账单覆盖所有厂商，不必逐家开户，就用 Kunavo。
