## AI 摘要

5倍上下文压缩对GPT-5.5的最终任务结果影响出奇地小。

压缩后的智能体在统计上与完整上下文版本同样成功。

变化的是达成方式：它更重度依赖检索来重建被丢弃的信息。

## 正文

5× context compression did surprisingly little to GPT-5.5’s final task result.

The compressed agent remained statistically as successful as the full-context version.

What changed was how it got there: it relied much more heavily on retrieval to reconstruct dropped information.
