支持超长上下文的 AI 模型
对比支持 200K tokens 及以上上下文窗口的 AI 模型 —— 长文档与大规模代码场景。
这是什么？
- 长上下文 LLM 可一次接受 200K tokens 或更长的输入 —— 足以装下整本书、多文件代码库或数小时转写稿。
- 部分模型可扩展到 1M、2M 甚至 10M tokens 的上下文。
为什么重要
- 长上下文是 RAG 的替代或补充 —— 你可以直接粘贴全部内容，而不只检索片段。
- 注意：有效召回会随输入变长而下降，且按百万 token 计价会让长提示很贵。
- 部分厂商在 200K 以上有阶梯价 —— 详见各模型详情页的 >200K 费率。

Frequently asked questions
How many AI models support 200K+ 上下文窗口?
693 canonical models in our database currently support 200K+ 上下文窗口. The list is regenerated on every data refresh, so it always reflects the latest releases tracked in our catalogue.
What is the cheapest model with 200K+ 上下文窗口?
Ling-2.6-flash from openrouter is currently the lowest-priced option, at $0.010 per 1M input tokens and $0.030 per 1M output tokens. The full table above is sorted price-ascending.
Which model with 200K+ 上下文窗口 has the largest context window?
Qwen Long (Alibaba (Qwen)) leads on context at 10M tokens. This may matter if you also need long-document understanding alongside 200K+ 上下文窗口.
Which models are available on the most providers?
Production-readiness usually correlates with how many independent providers host the same weights. The top three by provider count are: GLM-5.2 (75), Kimi K2.6 (63), DeepSeek V4 Pro (55).
How is 200K+ 上下文窗口 different from a regular LLM?
Long-context models accept ≥ 200K input tokens — enough for entire books, codebases or hours of transcripts in one prompt. Effective recall and per-token pricing both degrade with input length, so 'big context' is not always the right choice over RAG.
How often is this list updated?
Daily. Our data pipeline syncs once a day, regenerates the canonical model list, and rebuilds these pages so newly released models appear within 24 hours.
