模型价格对比器
Compare model price, context, source, and capabilities before routing traffic.
并排比较大模型 API 价格——每百万 token 的输入/输出成本、混合价、上下文窗口、能力和数据来源,在把生产流量路由出去之前看清楚。包含国内与全球提供方,便于在成本之外权衡地域适配。
- 按每百万 token 混合价对模型排序
- 查看上下文窗口、工具/JSON/视觉支持与生产适配
- 找到既满足能力又最便宜的模型

如何公平地比较模型价格？
用按真实比例加权输入与输出的混合成本,并统一货币。对话密集型流量下,输出便宜但输入贵可能颠覆排名。
这些价格是实时的吗？
价格来自 NextModel 目录,每个模型带来源标签。大流量上线前请向提供方再次确认。
