Questions & Answers

What is PaperQA2?
PaperQA2 is a package for high-accuracy Retrieval Augmented Generation (RAG) on various document types, including PDFs, text files, and scientific literature. It is engineered to provide grounded responses with in-text citations for tasks like question answering and summarization.
Who is PaperQA2 designed for?
PaperQA2 is primarily designed for researchers and individuals working with scientific literature and complex documents. It targets users who require accurate, citation-backed answers, summaries, and contradiction detection from a collection of papers or technical texts.
How does PaperQA2 differ from other RAG frameworks like LlamaIndex or LangChain?
PaperQA2 differentiates itself by its specialized focus on scientific literature, offering document metadata-awareness in embeddings and LLM-based re-ranking and contextual summarization (RCS). It aims for 'superhuman performance' in scientific tasks with strong citation grounding and agentic RAG capabilities, unlike more general frameworks.
When should I use PaperQA2?
You should use PaperQA2 when you need to extract precise, cited information from a collection of scientific papers, technical documents, or code files. It is particularly effective for complex tasks such as answering specific questions, generating summaries, or detecting contradictions within your document set.
What technical components does PaperQA2 use?
PaperQA2 utilizes several key technical components including Semantic Scholar and Crossref for metadata, LiteLLM for model integration, Pydantic for data validation, and Tantivy for full-text search. By default, it uses OpenAI embeddings and models with a Numpy vector database for document embedding and search, but supports customization.
