Summary

OpenViking addresses AI Agent context management challenges—fragmentation, surging demand, and poor retrieval—by offering an open-source context database. It unifies memories, resources, and skills via a file system paradigm, enabling hierarchical context delivery and self-evolving agent capabilities for developers.

How It Works

The core innovation is a "file system paradigm" that maps agent context (memories, resources, skills) to a viking:// URI structure, treating context like files and directories for unified, deterministic manipulation. It employs tiered context loading (L0 Abstract, L1 Overview, L2 Details) for efficient, on-demand retrieval, significantly reducing token costs. "Directory Recursive Retrieval" combines intent analysis with vector search and hierarchical directory traversal for more globally accurate context acquisition. Automatic session management extracts long-term memories, enabling agents to learn and improve over time.

Quick Start & Requirements

• Installation: pip install openviking
• Prerequisites: Python 3.9+, Linux/macOS/Windows, network. Requires VLM and Embedding models (OpenAI, Volcengine Doubao, or compatible APIs).
• Configuration: An ov.conf file is mandatory, specifying model service endpoints, API keys, provider types, and model names. The OPENVIKING_CONFIG_FILE environment variable must point to this configuration.
• Example: A Python script demonstrates core functionalities: adding resources, listing, reading, semantic search, and retrieving abstracts/overviews.
• Documentation: Available via the header "Docs" link and "Full Documentation."

Highlighted Details

• File System Paradigm: Unifies context management beyond flat RAG into a hierarchical, traceable structure.
• Tiered Context: L0/L1/L2 layers optimize token usage and retrieval depth.
• Recursive Retrieval: Enhances context accuracy via hierarchical directory exploration alongside semantic search.
• Self-Iteration: Automatic memory extraction enables agents to learn and improve.

Maintenance & Community

Limitations & Caveats

As an early-stage project, OpenViking may have instability or incomplete features. Setup requires careful configuration of external model service APIs, which may incur costs.
