AI Memory Part 1 — Chain of Density

Author: .ktg

Chain of Density does more than shorten text. Used properly, it summarizes and condenses as a context extension protocol.

Overview

Reframes Chain of Density (CoD) — typically used for summarization — as a context extension mechanism for LLMs. The key insight: CoD’s value isn’t human readability, but achieving high-fidelity machine recall (9.52/10) for fresh AI instances.

Key Concepts

  • Progressive Density Layering (PDL): Iteratively compress text with increasing density targets, each pass evaluated for fidelity
  • The Carry Packet: Structured context handoff between sessions — the compressed artifact that carries memory forward
  • Cross-model validated: Tested on Claude, Grok-4
  • Iterative Density by Experts: Different “expert” compressors for different content types
