Cognitive Architecture
Cognitive architecture in AI is the structural framework that defines how an intelligent agent perceives its environment, processes information, stores and retrieves knowledge, makes decisions, and executes actions.
Understanding Cognitive Architecture
Just as cognitive architecture in psychology describes the fundamental mental structures underlying human intelligence, AI cognitive architecture describes the computational structures underlying agent intelligence. A well-designed cognitive architecture specifies the perception module (how the agent reads inputs), working memory (what information is active at any time), long-term memory (how knowledge is stored and retrieved), the reasoning module (how decisions are made), the action module (how the agent acts on the world), and the learning module (how the agent improves from experience). LangGraph provides a graph-based cognitive architecture for structuring these components in AI agents.
How GAIA Uses Cognitive Architecture
GAIA's cognitive architecture is built on LangGraph, with distinct components for perception (reading emails, calendar events, messages), memory (ChromaDB, PostgreSQL, MongoDB, graph memory), reasoning (LLM-based decision making), planning (workflow orchestration), and action (MCP tool calls). This structured architecture makes GAIA's behavior predictable, debuggable, and extensible.

LangGraph
LangGraph is a framework for building stateful, multi-agent AI applications that supports complex workflows with cycles, branching, conditional logic, and persistent state management.
AI Agent
An AI agent is an autonomous software system that perceives its environment, reasons about what to do, and takes actions to achieve specific goals without continuous human direction.
Agent Memory
Agent memory is the capability of an AI agent to store, retrieve, and utilize information from past interactions, observations, and actions to inform future behavior, enabling persistent context across sessions.
AI Orchestration
AI orchestration is the coordination of multiple AI agents, models, and tools to work together in completing complex, multi-step tasks that no single component could handle alone.
Agentic AI
Agentic AI describes artificial intelligence systems designed to operate autonomously, making decisions and executing multi-step tasks with minimal human oversight.
