PCS is a vendor-neutral architectural standard that defines the externalization of persistent cognitive state from AI models into durable, auditable systems.

 

What PCS is:

• A normative specification (PCS-CORE)
• A conformance test suite (PCS-CTS)
• A certification framework (PCS-L1–L4)
• A registry of cognitive state types

 

What PCS is Not:

• Not an AI model
• Not a framework
• Not a SaaS platform
• Not a service offering
•  

PCS is designed to be implemented by any organization building AI systems requiring persistence, governance, or model portability.

Implementation of PCS may require licenses to patent rights held by Exocortical Concepts, Inc.
