bigRAG is an open-source RAG platform built on top of Turbopuffer for fast ingestion and retrieval, supporting multiple document formats and embedding models.

The tweet thread highlights the importance of infrastructure in AI research, exemplified by the collaboration between turbopuffer and SID AI to train the SID-1 agentic search model using large-scale RL, achieving 1.9x recall over RAG+rerank and 24x faster/99% cheaper than GPT-5.1.
