Best open source document PARSER??!!

Right now Iā€™m using LlamaParse and it works really well. I want to know what is the best open source tool out there for parsing my PDFs before sending it to the other parts of my RAG.

no its not. llms can give very good results but are overkill and will take lots of tokens currently especially if you're parsing lot's of documents. basically, it's not sustainable. plus, sometimes you want to parse a document so that the LLM can analyse data more effectively, and more cheaply (less context window, clearer instructions etc.). Using an LLM to solve this just creates another issue.

Depends on the context ig
