Fable 5 alone is smart, but with Karpathy’s LLM Wiki, it becomes unstoppable. Every fact, context, and prompt is absorbed, creating a second brain that thinks ahead.. Ai Fire 101, 🔥 Ai Fire Academy.
TL;DR
An AI second brain helps your AI read, connect, and reuse your own knowledge instead of searching through messy notes every time.
This setup uses Obsidian, Claude Code, and Karpathy’s LLM Wiki idea to turn videos, PDFs, meeting notes, transcripts, and articles into linked markdown pages. The AI creates summaries, key takeaways, concept pages, and backlinks automatically.
The real value comes from routing. Your AI can move through the index, log, wiki pages, and backlinks to find the right context faster. Once the system has enough data, Fable 5 can turn that context into clean resources, business recaps, content ideas, and cross-source insights.
Key points
One source can become 5–10 connected wiki pages.
Avoid treating your AI second brain as a random storage folder.
Start simple, add sources often, and update ingest rules when the structure feels messy.

Introduction
Andrej Karpathy, OpenAI co-founder, former Tesla AI director, and a member of Anthropic’s pre-training team, published a GitHub Gist called llm-wiki.md. It went viral almost immediately.
The thing is, it’s not code or a product. It’s a pattern, a single markdown file designed to be copy-pasted into an Claude Code or Codex, which then builds the actual system for you based on your specific needs.
