The MetaSys AI Glossary
Plain-language definitions of the AI, automation, data, cloud, and logistics terms we use across our work. Written for decision-makers, not just engineers, and linked to the capabilities and guides where each idea shows up in practice.
Agentic AI & LLMs
Agentic AI
AI systems that plan, decide, and take action across multi-step workflows with limited human input, instead of only answering a single prompt. They monitor, evaluate options, and act inside your tools.
Agentic AI SystemsAI Agent
Software that pursues a goal by choosing its own sequence of tool calls, rather than following a fixed script.
Agentic AI SystemsAI Assistant
A conversational AI tool that answers questions, drafts content, or completes a single requested task within one exchange, rather than independently planning and executing a multi-step task.
Chatbot
A conversational interface, rule-based or model-driven, that carries on a scripted or pattern-matched exchange to answer common questions or complete simple, predefined transactions.
Large Language Model (LLM)
A model trained on large volumes of text that predicts and generates language. LLMs power reasoning, summarization, classification, and the planning loop inside agents.
Multi-Agent System
An architecture where specialist agents work in sequence or in parallel, handing off tasks with shared memory and state. Used when one agent cannot own an end-to-end process alone.
Multi-Agent Systems guideRetrieval-Augmented Generation (RAG)
A pattern that retrieves relevant documents from your own data and feeds them to the model at query time, so answers are grounded in your knowledge rather than the model's training alone.
RAG implementation guideHuman-in-the-Loop
A design where the agent pauses at defined gates for a person to review, approve, or correct an action before it executes. It keeps autonomy bounded where the cost of error is high.
AI & Intelligent AutomationFine-Tuning
Further training of a base model on domain-specific examples so it performs better on your task, terminology, and edge cases than a general-purpose model.
AI engineering stackContext Window
The amount of text a model can consider at once. It limits how much history, retrieved data, and instruction the model can use in a single step, and it shapes how systems are architected.
Model Context Protocol (MCP)
An open protocol for how an AI model discovers and calls external tools, data sources, and services. It makes each tool integration reusable across models instead of bespoke glue rewritten per vendor.
AI engineering stackEvals
A repeatable test suite for an AI system, scoring accuracy, cost, and latency on real task examples. Without evals you are shipping on assumptions, and you cannot tell whether a model swap made things better or worse.
How to evaluate an AI agentGuardrails
Constraints that stop a model from acting outside an approved range, checked before an action is executed rather than after.
Coding Agent
An AI tool that reads a codebase, plans a change, edits files, and runs tests, rather than only suggesting the next line.
AI engineering stackOpen-Weight Model
A model whose weights are published so it can be run, fine-tuned, and hosted on infrastructure you control, rather than reached only through a vendor API.
AI engineering stackAutomation
Intelligent Automation
Automation that combines rules with machine learning so it can handle variation, unstructured inputs, and judgment, not just fixed scripts.
AI & Intelligent AutomationRobotic Process Automation (RPA)
Rule-based bots that mimic clicks and keystrokes to move data between systems. Reliable for stable, structured tasks, but brittle when inputs change.
RPA vs AI automationWorkflow Orchestration
Coordinating multiple steps, tools, and approvals into one reliable flow with error handling, retries, and observability.
AI workflow automation guideIntelligent Process Automation (IPA)
An umbrella for combining RPA, AI, and orchestration to automate end-to-end business processes rather than isolated tasks.
IPA guideProcess Mining
Analyzing system event logs to reconstruct how a process actually runs today, variants and exceptions included, before deciding what to automate. Skipping this step is a common reason automation projects target the wrong workflow.
AI & Intelligent AutomationAI Center of Excellence
A cross-functional group that sets standards, shares reusable components, and governs how AI and automation projects get approved and scaled across an organization, rather than leaving each team to solve the same problems independently.
AI & Intelligent AutomationData & Machine Learning
Data Platform
The ingestion, storage, transformation, and serving layer that makes data usable for analytics and AI. Without it, AI projects stall on data access and quality.
Data & AI PlatformsData Lakehouse
An architecture that combines the low-cost storage of a data lake with the structure and performance of a warehouse, so one platform serves both analytics and machine learning.
Data lakehouse architectureVector Database
A store optimized for embeddings, the numeric representations of text and images. It powers semantic search and the retrieval step in RAG systems. Selecting one is a core decision in any data and AI platform build.
Data & AI PlatformsFeature Store
A central repository that stores, versions, and serves the input features machine learning models use, so training and production inference read the same definitions instead of drifting apart.
Data & AI PlatformsData Mesh
A decentralized approach where domain teams own and publish their own data as a product, instead of one central team owning a single pipeline. It is often weighed against a data lakehouse depending on how an organization is structured.
Data & AI PlatformsMLOps
The practices and tooling for deploying, monitoring, and retraining machine learning models in production, the way DevOps does for software.
Cloud & DevOps EngineeringLLMOps
MLOps adapted for large language models: prompt and version management, evaluation pipelines, cost and latency tracking per request, and monitoring for drift in a model's outputs rather than only its accuracy metrics.
Cloud & DevOps EngineeringReal-Time Pipeline
A streaming data flow that processes events as they happen, enabling live dashboards, monitoring agents, and instant decisions instead of overnight batches.
Real-time pipeline guideCloud & Delivery
Cloud-Native
Software built to run on cloud infrastructure using containers, managed services, and automation, so it scales elastically and ships frequently.
Cloud & DevOps EngineeringDevOps
A practice that unifies development and operations with automated build, test, and deploy pipelines to release software faster and more safely.
DevOps for AI teamsGlobal Capability Center (GCC)
A dedicated offshore engineering team that operates as an extension of your company, with your processes and standards, rather than a per-project vendor.
Global Capability CentersObservability
The ability to understand a system's internal state from its outputs, traces, logs, and metrics. For AI systems it also covers accuracy, latency, cost, and drift.
FinOps for AI
The practice of tracking and controlling cloud and model inference spend per workload, so AI costs are visible and accountable rather than discovered on the monthly bill.
Cloud & DevOps EngineeringLogistics & Dispatch
Load Board
An online marketplace, such as DAT or Truckstop.com, where carriers find available freight and brokers post loads that need a truck.
Truck Dispatch ServicesDispatch Fee
The percentage of a load's gross revenue a dispatch service charges for finding freight, negotiating the rate, and handling paperwork on the carrier's behalf.
Truck Dispatch ServicesMC Number (MC Authority)
The Motor Carrier number issued by the FMCSA that legally authorizes a company to transport regulated freight for compensation.
MC Lease and Authority PlacementDOT Number
The identifier issued by the FMCSA used to track a carrier's safety information, required alongside or instead of an MC number depending on the type of operation.
MC Lease and Authority PlacementLease-On
An arrangement where a truck runs under another company's MC/DOT operating authority instead of, or while waiting for, its own.
MC Lease and Authority PlacementFreight Broker
A licensed intermediary that arranges transportation between a shipper and a carrier, earning the difference between what the shipper pays and what the carrier is paid.
Brokerage AccessBroker Agent
A representative who sources carriers and covers loads under a licensed brokerage's authority, without holding a brokerage license themselves.
Brokerage AccessDispatcher
A person or service that works for a carrier to find loads, negotiate rates, and manage day-to-day logistics, distinct from a broker who represents the shipper's side.
Truck Dispatch ServicesFactoring (Invoice Factoring)
Selling unpaid freight invoices to a third party at a discount for immediate cash, instead of waiting the standard 30 to 45 days for broker payment.
Freight FactoringDetention Pay
Compensation owed to a carrier when a shipper or receiver holds a truck beyond the agreed free time at a pickup or delivery location.
Deadhead Miles
Miles driven with an empty trailer between delivering one load and picking up the next, unpaid unless negotiated otherwise.
Hours of Service (HOS)
FMCSA regulations limiting how many hours a driver may drive and must rest, tracked to prevent fatigue-related accidents.
ELD (Electronic Logging Device)
A device that automatically records driving time and Hours of Service compliance, mandated by the FMCSA for most commercial drivers.
TMS (Transportation Management System)
Software used to plan, execute, and track freight movement, from load assignment to invoicing.
