Episode Details

OpenViking from Volcengine rethinks how AI agents store and retrieve context — replacing the standard vector database + skill files stack with a single browsable filesystem. This episode unpacks the viking:// URI protocol, the three-tier L0/L1/L2 abstraction that cuts token usage by up to 91%, and how the system's directory-tree structure makes retrieval observable and debuggable. We cover the Rust, Python, and C++ codebase, the asynchronous memory extraction pipeline, and what "self-evolving" means in practice — memories that merge, patch, and update without creating duplicates.
