English(EN) Why more context makes your AI answers worse

大型语言模型尽管拥有大型上下文窗口，但在处理长上下文时仍会遇到困难

作者 PulseAugur 编辑部 · [3 个来源] ·

尽管声称拥有大型上下文窗口，但大型语言模型在处理超过一定阈值的信息时常常会遇到困难。注意力机制的计算成本随输入大小呈二次方增长，并且当关键信息被置于长提示的中间时，模型的性能往往会下降。此外，在大量上下文中区分相似但不正确的数据点会进一步降低性能，这表明发送较少、更集中的信息并利用提示结构可以改善结果。 AI

影响 强调大型上下文窗口并不等同于有效记忆，这影响了开发人员应如何构建提示以获得更好的AI性能。

排序理由 该集群讨论了LLM上下文窗口和注意力机制的局限性，这是对现有技术的分析，而不是新的发布或研究里程碑。
