From RAG to Compiled Knowledge Systems — Semantica (inspired by Karpathy)

Semantica: From RAG to Compiled Knowledge Systems

Inspired by Andrej Karpathy’s “LLM Wiki” idea.


What We’re Building

We’re building Semantica — a semantic layer that transforms unstructured data into persistent, structured knowledge graphs with reasoning and provenance.

The goal is simple:

Move beyond retrieval systems → toward systems that build and maintain understanding

The Problem with RAG

Most LLM systems today rely on retrieval (RAG):

  • Upload documents
  • Retrieve relevant chunks at query time
  • Generate answers

This works — but it has a fundamental limitation:

The system re-discovers knowledge from scratch on every query.

There is no accumulation. No memory. No evolving understanding.


The Shift: Retrieval → Compilation

As Andrej Karpathy points out, the real shift is:

From retrieving fragments → to compiling knowledge

Instead of repeatedly searching raw documents, systems should:

  • Extract entities and relationships
  • Build structured representations
  • Maintain cross-references
  • Continuously update knowledge

The system evolves from:

documents → retrieval → answers

to:

documents → structured knowledge → evolving understanding → answers

How Semantica Fits

Semantica is built around this exact paradigm.

Instead of chunk-based retrieval, it focuses on:

  • Entity extraction & linking
  • Graph-based knowledge representation
  • Provenance tracking (why something is true)
  • Reasoning over structured context

This creates a persistent semantic layer that LLMs can rely on — rather than re-deriving context every time.


Why This Matters

The hardest part of knowledge systems isn’t storage — it’s maintenance.

Humans don’t scale at:

  • updating cross-references
  • resolving inconsistencies
  • keeping knowledge fresh

LLMs can.

This is where compiled systems win.


Final Thought

RAG retrieves. Semantica builds understanding.

We’re moving from:

“find relevant text”

to:

“construct and evolve knowledge”
