最划算的三家
| # | 服务商 | 输入 | 输出 | 合计 | 精度 |
|---|---|---|---|---|---|
| 1 | Baidu | $0.033 | $0.132 | $0.165 | FP8，精度接近原版 |
| 2 | Sail Research | $0.090 | $0.250 | $0.340 | FP4，精度有損，適合非關鍵任務 |
| 3 | Sail Research | $0.090 | $0.250 | $0.340 | FP4，精度有損，適合非關鍵任務 |
怎么选
只看价格会踩坑。建议按这个顺序判断：先看量化精度是否满足任务要求，再看上下文是否够用，最后才比价格。同一个模型在不同服务商之间可以随时切换，配置里换个 base_url 和 key 即可，不需要改代码逻辑。
官方 API 的优势是稳定性与文档完整，第三方服务商的优势是价格。对成本敏感的批量任务，用第三方通常能省一半以上；对稳定性要求高的线上服务，官方或大厂云服务更稳。
