In addition to AI-native frameworks, traditional software
or cloud service providers have also expanded their service
range. For instance, Verba7, provided by the vector database
company Weaviate, focuses on personal assistants. Amazon
offers its users the intelligent enterprise search service tool
Kendra, based on RAG thinking. Users can search in different
content repositories through built-in connectors.

on the existing technical stack, while the optimization of the
technical stack’s functions further promotes the development
of RAG technology. Overall, the technical stack of RAG’s

plications have gradually emerged, but an all-in-one platform
still needs to be refined.
