窗口大小有代价，够用比拉满更划算。Window size has a price; enough beats maximum.
上下文窗口越大，长文档就处理得越好。The larger the context window, the better long documents get handled.
标称窗口说明可处理的长度，不保证每段信息都被同样有效地利用。更长输入还可能增加内存与延迟，应按任务比较资料覆盖、答案质量和成本。A stated context window describes capacity, not equally effective use of every passage. Longer input can add memory use and latency. Compare evidence coverage, answer quality and cost for the task.
例子与判断Example and interpretation
以下是教学情境，不是本站运行或实测记录。A teaching scenario, not a measured or executed site test.
材料只有三页时，先提供相关段落和明确问题。若要查一百页政策的例外条件，再比较整篇输入、分段检索及其成本。窗口容量和找到正确信息是不同的要求。For three pages, start with relevant passages and a clear question. For exceptions across a hundred-page policy, compare full input and retrieval with their costs. Capacity and finding the right information are distinct requirements.
