SKULD
BRAIN-FIRST AI
AI with its own brain — not the LLM. A persistent mind that remembers, learns, and decides what matters.
Imagine every person with their own Jarvis. Knowledge isn't a privilege — it's a right. That future starts with giving AI its own brain.
Every piece of knowledge becomes a typed node — fact, preference, procedure, hypothesis — with confidence scores and source tracing. The graph grows and prunes across sessions. Close the tab. The brain stays.
SEC discovers what's worth observing from prediction errors alone. No labels. No reward engineering. Validated across 7 experimental systems.
Same task ×10: token use drops 54.9%, LLM calls drop 55.6%, quality unchanged. The inflection at iteration 3→4 is when the brain bypasses the LLM entirely.
Three tasks. Three different cognitive behaviors. Same brain.
Searched the web, extracted 6 new beliefs — market size, funding trends, key investors. Standard observation path.
Zero new beliefs. Zero searches. Wrote directly from existing knowledge in the belief graph. The brain already knew enough.
Told not to search — but it did. It judged its knowledge about "what beliefs are" was insufficient, and looked it up. Then stored the answers in its own belief graph.

Skuld ran autonomously for 240 cycles across two experiments. Here's what happened.
5 seed beliefs. 65 autonomous cycles. It grew, abandoned goals — and decided to learn something no one asked.
Emergent: Skuld extracted "negative emotions can promote growth" and "avoid threatening language" — beliefs no one asked it to form.
It decided on its own.
We injected 955 seed beliefs across 70+ topics. Over 127 cycles, Skuld kept only what it could verify — and specialized on its own.
Five topic directions entered. One specialist emerged. SEC discovered where the world was still changing — cloud computing costs, the only domain with fresh data each cycle — and discarded everything else.
Knowledge metabolism: 1 new verified belief every ~10.7 cycles. The Brain breathes.
