The People Who Ship series brings behind-the-scenes stories from developers building production-grade AI applications using MongoDB. In this episode, John Ziegler shares insights learned while developing Central RAG, a centralized infrastructure that enables teams to rapidly build RAG-based chatbots and copilots for diverse use cases. Key takeaways include enforcing access controls across all operations, anchoring evaluations in the problem being solved, and educating users on what's possible and what's not. The backbone of Central RAG is the Credal tool, which provides a platform for teams to create AI applications on top of their data.
