还是从系统规格书的介绍中看到的。系统规格书的价值在于仔细明确的定义系统功能。列举了系统功能、运行、服务约束的方方面面细节。

The potency of System Specifications emerges from their characteristics – they are exhaustive, explicit and definitive. These detailed documents act as a blueprint, outlining the nitty-gritty of a system’s functional, operational, and servicing constraints.

这里 nitty-gritty 的意思是基本事实、本质实情。

一般在美国的黑人爵士乐中会用到很多。nit 是虱子跳蚤的虫卵。grit 是细石子、沙粒。两者应该都是很小很小的东西。所以放在一起可以表示某些细节的东西。大概可以意会是细枝末节。

在这篇文章中《This new tool can tell you whether AI has stolen your work》,作者Alex Perry介绍了避免被 AI 侵权的一个工具,就是在自己的图片、视频等文件中插入一些非常细微的数据,使得 AI 训练的时候会出错,而普通人查阅又很正常。

The idea of a copyright trap isn’t new to the world, having previously been used for other types of media — but it is new to AI. The nitty-gritty technical details are kind of a lot to parse, but the idea is that strings of gibberish text would be hidden somewhere on a page —like in the source code, for instance— and would be detectable if used to train large language models.

这里作者用 nitty-gritty 这个词表示微乎其微不可见的数据。
