To sing the praises of Bedrock again, it does have continuous pre-training as well as RAG “knowledge bases”. The former is based on JSON fragments and the RAG stuff is PDFs and other document formats.

With regards to its efficacy, I haven’t gone to production with it yet but I was reasonably impressed.

I uploaded 100 legal case documents to Bedrock via Claude and could push it pretty hard asking about the various cases and for situations across the knowledge base.

It did feel like it broke down and got confused at a certain point of complexity of questioning, but I still think it’s already useful as a “copilot” or search engine and surely it will only improve over time.
