Knowledge graph retrieval tool for AI agents

Description

👉 SurrealDB Solutions Engineer, Martin Schaer, walks you through building a knowledge graph retrieval tool for a Pydantic AI agent. Filmed at our London meetup, this video explores querying a SurrealDB knowledge graph directly (without extra abstraction), maintaining production-grade type safety, and getting full-stack observability - beyond just the LLM calls. 🔗 Links Slides: https://docs.google.com/presentation/d/1pYBvtYHyktWPMoG836u8GVPwf1HxBzDZU6Ayyi72MZE/edit?usp=sharing GitHub: https://github.com/surrealdb/kaig/tree/main/examples/knowledge-graph Chapters 00:00 Intro + what we’re building 00:30 SurrealDB overview (multi-model + SurrealQL) 03:29 Knowledge graphs basics (explicit vs inferred) 06:53 Why agents need KGs + vectors (and when to use hybrid) 12:00 Building a knowledge graph: ETL (parse → chunk → embed → extract → dedupe → enrich → load) 21:19 Surrealist walkthrough (schema + navigating the graph) 23:38 Retrieval approaches: RAG vs agentic tool-calling 26:19 Pydantic AI retrieval tool + SurrealQL query patterns 29:28 Observability with Logfire (end-to-end tracing) 30:55 Q&A SurrealDB: ☁️ Surreal Cloud: https://surrealdb.com/cloud 🎩 Surrealist: https://surrealdb.com/surrealist 🎓 SurrealDB University: https://surrealdb.com/learn 🌍 SurrealDB Website: https://surrealdb.com/ 👉 SurrealDB GitHub: https://github.com/surrealdb/surrealdb 🐦 SurrealDB Twitter: https://twitter.com/surrealdb 👨‍💻 SurrealDB LinkedIn: https://www.linkedin.com/company/surrealdb/ 👉 SurrealDB Discord: https://discord.com/invite/surrealdb 📸 SurrealDB Instagram: https://www.instagram.com/surrealdb 👚 Shop the merch: https://surrealdb.store/ What is SurrealDB?
