ロングコンテキストに対応した AI モデル
200K トークン以上のコンテキストを扱える LLM の比較。
これは何か
- ロングコンテキスト LLM は一度のプロンプトに 200K トークン以上を受け付けられます —— 書籍一枚、複数ファイルのコードベース、長時間の書き起こしなど。
- 一部モデルは 1M・2M トークン、さらに大規模まで拡張します。
なぜ重要か
- RAG の代替または補完になります —— チャンク検索の代わりに全文を貼れる場合があります。
- 入力が長くなると実効的な想起は低下しやすく、長プロンプトは百万トークン単価で高くなりがちです。
- 200K 超で段階価格を設けるベンダーもあります —— 詳細は各モデルページの >200K レートを参照してください。

Frequently asked questions
How many AI models support 200K+ コンテキスト?
509 canonical models in our database currently support 200K+ コンテキスト. 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+ コンテキスト?
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+ コンテキスト 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+ コンテキスト.
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: Kimi K2.6 (49), Kimi K2.5 (48), GLM-5.1 (47).
How is 200K+ コンテキスト 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.
