使用 LangChain 来自建 pdf 资料库效果如何？

[Tilie]

有谁试过么？

[UltraXiaoZi]

能用 但是不走微调的话缺陷不少

你可以试用一下 目前优化最好的 https://www.mendable.ai/

代码都是开源的 用零代码平台 也不用写代码

但是需要和向量数据库、gptapi 一块使用 功能比模糊搜索好很多

@UltraXiaoZi 官方说不是全开源呀
Are you open-source?
We are starting to open source some of our technology, but currently most of it is not. However, we're strongly considering moving to a more open-source model. If you have input here, please message us [e-mail].
