How to choose Retrieval Augmented Generation (RAG) Software
Start by naming the layer you are missing. If an agent needs live web results, the question is a search API and the published rates are directly comparable: Exa lists $4 per 1,000 lite searches, Parallel from $1 per 1,000 requests, Tavily $0.008 per credit and Linkup from $0.005 per search. If the problem is that your PDFs arrive as noise, it is a parsing purchase instead, and there the rates are per page: Unstructured at $0.015, Reducto from $1 per 1,000 pages on its smaller model, Contextual AI at $3 per 1,000 for basic text. If you are standing up the whole sequence and do not want to assemble it, look at the managed pipelines, where Ragie, Morphik and Vectara each sell ingestion, search, ranking and answering as one service. If you already have a store and your results are simply poor, the cheapest fix is usually a reranker rather than a rebuild: Voyage AI, ZeroEntropy and mixedbread all publish per-token rates for that one step. Then test on your own documents before you commit. Published parsing rates assume clean input, and the mode you will actually need on scans and tables often costs several times the headline figure. Finally, check where it can run. Unstructured, Morphik, Reducto and ZeroEntropy all offer a deployment inside your own cloud or on your own hardware, which is the only workable answer when the content cannot be sent anywhere.
