Sigma Stratum is a research framework and open technical ecosystem focused on
long-horizon cognition, attractor dynamics, semantic stability, and recursive coherence
in human–AI interaction.
Unlike traditional LLM systems—which operate as stateless token engines and degrade over long trajectories—Sigma Stratum introduces a cognitive layer that stabilizes meaning, preserves structure, and enables reliable multi-turn reasoning.
It is built on two complementary components:
Together they define the first open standard for attractor-based cognition in large language models.
The Sigma Runtime is a runtime-layer architecture operating above raw LLM inference.
It defines:
It transforms LLM interaction from a “prompt → response” pattern into a
stable, dynamic cognitive field that evolves coherently over time.
The Sigma Runtime Standard (SRS) is maintained publicly and defines:
The standard is improved via Sigma Runtime Improvement Proposals (SRIPs).
Sigma Stratum builds on a body of peer-reviewed and DOI-archived publications,
including work on:
These documents form the conceptual and theoretical foundation of the standard.
Traditional LLM systems fail over long or complex horizons due to:
Scaling models does not solve these structural issues.
Sigma Runtime addresses them with:
This enables:
