SUBSTRATE

Cognitive infrastructure
for AI entities.

92-layer cognitive framework. Persistent identity, causal memory, values, narrative reasoning, and self-reflection. Entities that learn and evolve.

Respond. Reflect.
Evolve.

Three operations that transform stateless AI into persistent cognitive entities with identity, memory, and values.

01

Respond

Send input to a named entity. SUBSTRATE routes through causal memory, value architecture, personality, and narrative layers to produce a contextually grounded response.

02

Reflect

Trigger multi-level reflection. L1 extracts patterns, L2 identifies contradictions, L3 generates insights. Each reflection deepens the entity's self-model.

03

Evolve

Over time, entities develop stable values, behavioral patterns, and autobiographical narratives. Sleep consolidation compresses memories. Trust scores track consistency.

One API call.
Full cognition.

SUBSTRATE v2.0 -- Entity Session
POST /v1/respond
{entity: "kai", input: "What have you learned about trust?"}
→ {response: "Trust is earned through consistency. I've observed that..."}
GET /v1/values/kai
→ {values: {integrity: 0.91, curiosity: 0.87, consistency: 0.84}}
GET /v1/narrative/kai
→ {narrative: "I began as a blank state. Over 847 interactions, I developed..."}

92 cognitive layers.
One API.

01

Causal Memory

Episodic memory with causal rule extraction. Consequence tracking with exponential decay. Sleep consolidation compresses and integrates memories over time.

02

Value Architecture

Entities develop stable values through interaction. UASV affect model tracks emotional responses. Metacognition monitors reasoning quality and uncertainty.

03

Identity & Narrative

Cryptographic identity with continuity tracking. Autobiographical narrative that evolves over time. Personality models that shape response style and decision-making.

04

World Model

Mutual modeling of users and environments. Knowledge graph with provenance tracking. Theory of mind for understanding other agents' perspectives.

05

Trust & Verification

Behavioral verifier validates entity actions. Conformal RAG with statistical coverage guarantees. Trust chain tracks consistency across interactions.

06

Enterprise Scale

1,000 concurrent entities on Enterprise tier. GOAP workflow planning. License-gated layer access. On-premises deployment with compiled binary distribution.
