英伟达研究称AI智能体极少需要长上下文窗口
Start here
2026年11月4日，英伟达（NVIDIA）研究团队在 arXiv 发表预印本论文指出，AI 智能体在实际应用中极少需要长上下文窗口。该研究显示，通过定期进行状态摘要并将工作上下文压缩至 16K 等短窗口后，Claude Opus 4.5 与 GPT 5.6 Sol 等前沿模型在 13 项长流程与长输入基准测试上的准确率几乎未受影响。

In an arXiv preprint, an NVIDIA research team showed that by using periodic state summarization to compress the working context down to short windows like 16K tokens, frontier models such as Claude Opus 4.5 and GPT 5.6 Sol suffered virtually no loss in accuracy across 13 long-horizon and long-input benchmarks.
