Introduction
Vessios is a wiki that writes itself — knowledge that compounds with every ingest and query.
Vessios is a knowledge management platform built on the Karpathy LLM Wiki pattern: instead of treating every question as a fresh, stateless retrieval problem, Vessios maintains a living wiki that grows and improves with use.
Standard RAG vs. Vessios
| Standard RAG | Vessios | |
|---|---|---|
| Knowledge handling | Re-derived from raw documents on every query (stateless) | Accumulated and compounded in a wiki (stateful) |
| Role of the LLM | Synthesizes an answer from scratch each time | Reads and extends an existing, curated wiki |
Three core operations
Vessios is built around three operations that work together to keep the wiki accurate and useful over time.
Ingest
A single ingest run creates 10–15 new wiki pages and strengthens related existing pages, rather than producing an isolated document summary.
Query
Good answers are written back into the wiki as new or reinforced pages, so the same question gets faster and better answered next time.
Lint
A weekly automated pass detects contradictions, orphaned pages, and stale content — a required part of the architecture, not an optional extra.
Why Lint matters
The biggest risk in any system that accumulates knowledge automatically is compounding hallucination: an error introduced during one ingest can be picked up and reinforced by later ingests and queries. Vessios treats Lint as a first-class, architecturally required component — run at least weekly, and immediately after any large ingest — specifically to contain this risk.
