Summary AllenAI's ai2-scholarqa-lib provides a system for answering scientific queries and generating literature reviews by synthesizing evidence from a vast academic corpus. It employs a Retrieval-Augmented Generation (RAG) architecture to automate report generation with clear attribution, targeting researchers and engineers needing efficient scientific literature processing.

How It Works The RAG architecture features a multi-component retrieval stage and a three-step generation pipeline. Retrieval uses the Semantic Scholar API for evidence passages, reranked by mixedbread-ai/mxbai-rerank-large-v1. Generation, defaulting to Claude Sonnet 3.7, extracts quotes, plans/clusters them into a structured outline, and generates section summaries, including literature review tables for comparative analysis.

Quick Start & Requirements Install via pip (pip install ai2-scholar-qa or pip install 'ai2-scholar-qa[all]') or use Docker (docker compose up --build). Requires environment variables: S2_API_KEY (Semantic Scholar), ANTHROPIC_API_KEY (LLM), and OPENAI_API_KEY (fallback/moderation). Docker build installs dependencies like PyTorch.
