Vertex AI search is (finally) catching up with advanced RAG features like VLM document parsing, chunking, citations, re-ranking, grounding generation/verification.
As usual, you will have to choose between an all-in-one closed-source monolytic solution like this or aggregating the best open-source solutions.
But this now looks, at least on paper, like a solid RAG/search solution with the key advantage of being serverless and scalable end-to-end.
Similar to the new features of Amazon Bedrock knowledge bases https://aws.amazon.com/bedrock/knowledge-bases/.
It is not easy to clone this with disparate components without investing time and money.
