Nagent AI

AI Agent Glossary

Plain-English definitions for agentic AI concepts — from autonomous execution to sovereign deployment.

A

Agentic AI
AI systems capable of autonomous, multi-step action — perceiving context, planning, and executing tasks without human intervention at each step.
Agent Orchestration
The coordination of multiple specialised AI agents working together on a shared goal, with routing, sequencing, and error-handling logic managing the flow.
Agent Smriti
Nagent's persistent memory layer that stores contextual knowledge, user preferences, and interaction history across sessions and agents.
Autonomous Execution
The ability of an AI agent to carry out a defined task from start to finish without requiring human approval at each step.

F

Feedback Loop
A mechanism where agent outputs are evaluated and used to improve future performance — either through human signals or automated evaluation.
Fine-tuning
The process of updating a language model's weights using domain-specific training data to improve performance on targeted tasks.
Function Calling
A capability in modern LLMs that allows the model to invoke external tools, APIs, and services in a structured, predictable way.

H

Human-in-the-Loop (HITL)
A workflow design pattern where an AI agent pauses at defined checkpoints to wait for human review or approval before proceeding.
Hallucination
When a language model generates content that is factually incorrect or fabricated, presented with apparent confidence.

K

KARMIC Feedback Loop
Nagent's proprietary continuous-learning engine that scores every agent output and uses that signal to automatically improve prompts, routing, and agent behaviour over time.
Knowledge Base
A structured repository of domain-specific information that agents can retrieve and reference when executing tasks.

L

LLM (Large Language Model)
A deep learning model trained on large text corpora that can generate, classify, summarise, and transform natural language.
LangChain
An open-source framework for building applications powered by language models, widely used for constructing agent pipelines.

M

Memory (Agent Memory)
The ability of an agent to retain and recall information from prior interactions — enabling personalisation, consistency, and context-awareness across sessions.
Multi-Agent System
An architecture where multiple specialised AI agents collaborate on a task, each handling the part of the problem it is best suited for.
Multi-Step Reasoning
The capacity of an AI agent to decompose a complex goal into sub-tasks, reason through them in sequence, and synthesise a final output.

P

Prompt Engineering
The practice of crafting and optimising the instructions given to an LLM to elicit more accurate, relevant, or structured outputs.
Programmatic SEO
The technique of generating large volumes of SEO-optimised pages from structured data, targeting long-tail search queries at scale.

R

RAG (Retrieval-Augmented Generation)
An architecture that combines a language model with a retrieval system — the model queries a knowledge base to ground its responses in relevant, up-to-date information.
ReAct (Reasoning + Acting)
A prompting pattern where an LLM alternates between reasoning steps and tool-use actions, mimicking how a human might tackle a problem.

S

Sovereign AI
An approach to AI deployment where an organisation retains full control over their AI infrastructure, data, and models — typically via private cloud or on-premise deployment.
System Prompt
Instructions passed to an LLM before the user message that define the agent's role, constraints, tone, and behaviour.

T

Tool Use (Function Calling)
The ability of an LLM to invoke external functions — APIs, databases, calculators, code runners — and incorporate the results into its response.
Token
The basic unit of text processed by a language model — roughly equivalent to a word or word-part. Context limits and costs are measured in tokens.

W

Workflow Automation
The use of software (including AI agents) to execute a repeatable sequence of business tasks with minimal human intervention.
