Historical Lineage
PRIMUS is the direct successor of CogPrime, the cognitive architecture described in Building Better Minds (2012) and Engineering General Intelligence (2014). CogPrime defined the same fundamental pattern — multiple memory systems, attention dynamics, goal-directed reasoning, cognitive synergy — but without the unified mathematical controls (weakness, geodesic effort) or the advanced components (TransWeave, SubRep, WILLIAM, ActPC-Chem) that the 2025 design adds. The deeper roots are described in Goertzel's 2021 General Theory of General Intelligence, which provides the theoretical framework these components instantiate.
CogPrime Theoretical Foundations
CogPrime was built on patternism — the philosophy that "mind is made of pattern" and cognition consists of recognizing patterns in environments and in oneself. The cognitive synergy hypothesis — that integration of diverse components produces intelligence gains no single process could achieve alone — was the central design thesis (see Cognitive Synergy).
Two additional CogPrime concepts that carry into PRIMUS:
-
Glocal memory: Memory items are stored as paired (key, map) structures where keys are localized representations and maps are distributed patterns of activation across the network — transcending the local/global dichotomy. Knowledge representation combines logical relationships with attention values weighted similarly to neural activations, enabling both explicit reasoning and emergent pattern dynamics.
-
Mind-world correspondence principle: The system's internal decomposition must naturally map from world-state sequences to mind-state sequences, ensuring that component design mirrors environmental structure. This guided CogPrime's insistence that internal dynamics map appropriately to real-world goal structures.
CogPrime also integrated DeSTIN (Deep SpatioTemporal Inference Network) as its sensorimotor perception layer — a hierarchical temporal memory system handling low-level learning separately from symbolic reasoning while maintaining dynamic feedback connections. In PRIMUS, this role is subsumed by QuantiMORK's sensory encodings and the broader neural-symbolic integration via Neural Spaces. (Provenance: official-site, wiki.opencog.org— CogPrime Overview)
System Interfaces and Dependencies
PRIMUS sits atop the Hyperon infrastructure stack:
-
AtomSpace / MORK — shared memory and control plane. Everything (facts, rules, tensors, motives, certificates, transfer maps) lives as Atoms.
-
MeTTa — PRIMUS is specified in MeTTa; the cognitive cycle is a MeTTa program operating over AtomSpaces.
-
DAS — distributed AtomSpace enables the ambient loop to run widely across a decentralized pool.
-
ASI Chain — RSpace/Rholang enables capability-secured execution, audit, and decentralized governance of cognitive processes.
Implementation Anchors
Open Problems / Research Directions
- Full integration of all PRIMUS components in a single running system (current state: individual components work; full orchestration is the Alpha release target)
- Practical validation of cognitive synergy thresholds — demonstrating emergent capability from component integration
- Scaling the ambient loop across distributed/decentralized AtomSpaces
- Self-modification pipeline implementation (five-stage: proposal → analysis → simulation → certification → deployment)
- Benchmarking PRIMUS against alternative AGI architectures on shared tasks
