模型短名单

适合成本敏感产品的低价 LLM API 模型

按真实价格、上下文和生产可用性挑低价 LLM API,路由前先估算月度成本。

这份候选名单适合什么用途: 低价 LLM API

标价最低往往不是好起点。分类、短摘要、路由、批量草稿,低价模型通常够用;要严谨推理或长链路 Agent 时,就容易翻车。先对齐任务,再看输入输出单价。这页把价格、上下文、能力、来源放在一张表里。上线前用 /tools/llm-cost-calculator 和 /pricing 算一遍月费。

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 2026-08-05

步骤

如何使用这份名单(低价 LLM API)

  1. 对照任务选模型。 先看「低价 LLM API」短名单是否覆盖你的真实任务,不要只比标价。
  2. 用同一批提示词试跑。 挑 2–3 个候选,用业务提示词对比质量与输出长度。
  3. 估算月费。 用价格页或成本计算器,按预计 token 量估算月度花费。
  4. 定兜底与预算。 定主模型、兜底模型,设项目预算后再接生产流量。

综合价格

推荐候选 低价 LLM API

先从候选名单开始,再用真实提示词测试,并在接入生产路由前比较月度成本。

常见问题

低价 LLM API 常见问题

目录里最便宜的模型是哪一个?

取决于汇率和输出长度。本目录 CNY 生产条目里,Doubao Seed 2.0 Mini 通常是最低价。

团队是否应该总是选最便宜的 LLM API?

不应该。低价模型适合可重复、低风险的工作;最终回答、复杂推理和编码 Agent 仍要和更强模型对比。

缓存和路由怎么压低低价模型的实际成本?

简单请求走便宜模型,安全时再缓存重复前缀,统一用一个 OpenAI 兼容 base URL。可用 /tools/llm-cost-calculator 粗算节省。
