选 LLM API 提供方首先是运维决策，其次才是价格决策。撑得起生产的提供方有四个共同点：目录够宽、可以跨模型路由；单价按模型按 key 可审计；一个 OpenAI 兼容端点，换提供方只改 base_url；费用管控能在财务找上门之前拦住失控任务。用这页的表对照评估任何提供方（包括 NextModel）：模型广度、上下文、来源、单价。兼容性看 /best/openai-compatible-gateway，要离开聚合市场的看 /best/openrouter-alternatives，决定前再核一遍 /pricing。
来源依据: NextModel 精选目录、提供方公开定价，以及可用时的 OpenRouter 元数据。 · 更新日期 2026-08-28

常见问题
目录广度、按模型的价格透明度、一个 OpenAI 兼容端点、key 级预算、可对账的用量报表。缺两条以上的提供方，问题会在事故里暴露，不会在选型时暴露。
深度只用一家时直连合理；一旦要跨厂商路由、要预算和 BYOK，网关把切换成本压到改 base_url 的量级。
按自己的真实用量结构比每百万 token 的输入输出单价，再算上缓存和路由的节省。这页的表列单价；/tools/llm-cost-calculator 可以折算月费。
没有。页面只描述模型来源与目录数据；合作声明只在单独核实后才出现。
