AI Agent Glossary

Everything you need to know about AI agents, infrastructure, and the technology that powers them. Plain-language definitions for technical and non-technical readers alike.

AI Agent

An autonomous software entity that perceives, reasons, decides, and acts within an environment to achieve specified goals.

AI Agent Infrastructure

The technology stack required to deploy, run, govern, and monitor AI agents in production environments.

Managed AI

Enterprise AI delivered as a fully managed service — vendor operates the AI engineering layer; customer configures workflows.

CISO-Compliant AI

Enterprise AI designed to clear the security review — deployment posture, audit governance, and compliance framework alignment built in from the deployment-posture layer.

Self-Hosted AI

AI infrastructure operated inside the customer's own environment under full operational and security control.

Knowledge Base

A structured repository of internal information used to ground AI agent responses in the organization's actual policies, procedures, and historical context.

Hardened Container

A container image built to satisfy enterprise security review — minimal attack surface, signed builds, alignment with CIS/STIG/NIST hardening benchmarks.

AI Orchestration

The layer that coordinates multi-step AI agent workflows across multiple systems, tools, and decision points.

LLM Hosting

The infrastructure layer that runs large language model inference for production AI workloads.

Vector Database

A database optimized for storing and searching high-dimensional embeddings — the technical foundation for semantic search and retrieval-augmented generation.

Retrieval-Augmented Generation

The pattern where AI agents retrieve relevant content from a knowledge base before generating a response — grounding outputs in organizational knowledge and reducing hallucination.

AI Compliance

Alignment of AI system deployment with the regulatory frameworks and audit/governance posture the customer's environment requires.

AI Security

The security posture of AI systems — covering model security, data security in inference, prompt-injection defense, supply-chain provenance, and deployment posture.

Prompt Engineering

The practice of structuring inputs to language models to elicit desired outputs reliably.

AI SLA

A service-level agreement covering AI system availability, latency, accuracy guarantees, escalation, and incident response.

Agentic AI

AI systems that exhibit autonomy, planning, tool use, and multi-step execution — the architecture pattern underlying modern AI agents.

AI Ops

The operational practices for running AI systems in production — lifecycle management, observability, drift detection, incident response, capacity planning, cost management.

Tool Integration

The layer that lets AI agents call external systems and APIs to take actions in the world.

Conversational AI

AI systems designed for natural-language interaction — typically chatbots, voice assistants, and customer-facing AI surfaces.

AI Infrastructure as a Service

The consumption model where AI agent infrastructure is delivered as a fully managed service — vendor operates, customer configures.

Multi-Tenant AI

The deployment pattern where AI infrastructure is shared across multiple customers with strict data isolation — distinct from dedicated single-tenant deployments.

Decision Intelligence

A discipline that combines data analytics, simulation, and decision modeling to support high-stakes organizational decisions.

Scenario Simulation

Modeling how a hypothetical future scenario will unfold across multiple stakeholders and decision branches.

Stakeholder Modeling

The discipline of representing how different stakeholder groups will respond to organizational decisions, communications, or events.

Audience Simulation

Modeling how a target audience will receive a message before it ships — for marketing, communications, decision intelligence, and pre-deployment rehearsal.

Agent-Based Modeling

A simulation approach where individual agents follow rules and interact to produce emergent system behavior — used in economics, epidemiology, urban planning, and AI-driven audience simulation.

Generative Engine Optimization

The discipline of making sure a brand is correctly represented in AI-mediated search — ChatGPT, Claude, Perplexity, Gemini, Google AI Overviews, Bing Copilot.

Answer Engine Optimization

The discipline of optimizing for direct-answer search surfaces — Google AI Overviews, Bing Copilot, ChatGPT, Perplexity, and the next wave of AI-mediated answer engines.

llms.txt

A proposed standard file at a website's root that gives AI engines a structured Markdown guide to the site's content — analogous to robots.txt for search crawlers, but designed for LLM ingestion.

AI Overviews Ranking

The practice of optimizing content to be cited in Google's AI Overviews — the AI-generated summary at the top of many Google search results.

AI Citation Monitoring

Tracking how a brand is cited (or not cited, or misquoted) across AI engines — the measurement layer underneath GEO and AEO remediation.
