Artificial intelligence extends far past traditional question-answering chatbots. Today’s AI reads files, operates software, discovers data, invokes tools, finishes multiple assignments, and collaborates with other artificial intelligence platforms. This evolution has introduced a multitude of fresh concepts, which a proper glossary helps clarify.
Core AI Terms
Artificial Intelligence
AI describes computer systems engineered to handle assignments typically requiring human intellect, such as comprehending language, analyzing imagery, generating forecasts, mapping out strategies, and executing decisions.
Machine Learning
Machine learning empowers computers to detect patterns within datasets and leverage those patterns for forecasting or decision-making, moving beyond strict reliance on fixed rule sets.
Deep Learning
Deep learning employs expansive neural networks to process intricate information, serving as the backbone for modern textual, visual, auditory, video, and general data applications.
Foundation Model
A foundation model is a massive AI model trained across a broad spectrum of data, designed to support a wide array of functions rather than a singular application.
Large Language Model (LLM)
An LLM centers on linguistic processing, capable of composing, condensing, translating, categorizing, explaining, and parsing written text.
Small Language Model (SLM)
An SLM features fewer parameters and demands less computational power, providing advantages in affordability, speedier outputs, and simpler local deployment.
Generative AI
Generative AI builds novel content based on a prompt or alternative input format, yielding text, graphics, audio, video, or software code.
Multimodal AI
Multimodal AI processes diverse information categories simultaneously—for instance, analyzing a photograph, understanding a text-based inquiry about it, and delivering a written reply.
Token
A token denotes a compact text segment processed by a model, which may equate to an entire word, a subword fragment, punctuation marks, or another fundamental unit.
Context Window
A context window determines the maximum data capacity a model can manage concurrently; expansive windows accommodate larger volumes of text, code, documents, or dialogue history.
Embeddings
Embeddings convert data points like text or graphics into numerical values, allowing systems to locate elements sharing semantic similarities.
RAG, Retrieval, and Grounding
Retrieval-Augmented Generation (RAG)
RAG enables an AI setup to retrieve relevant details from an external repository prior to generating a response, allowing enterprises to answer inquiries using proprietary documents, registries, or knowledge bases.
Grounding
Grounding tethers an AI-generated output to a specific reference point, establishing a factual foundation rather than relying strictly on parameters memorized during initial training.
Vector Database
A vector database archives embeddings and assists systems in identifying semantically aligned content, frequently serving as the backbone for RAG architectures.
These three concepts frequently operate in tandem: a vector database isolates pertinent material, RAG relays that material to the model, and grounding anchors the concluding answer to an authoritative source.

Agents and Tools
AI Agent
An AI agent pursues objectives across multiple stages, selecting actions, utilizing tools, scanning files, querying APIs, reviewing outcomes, and determining subsequent steps.
Agentic AI
Agentic AI pertains to frameworks capable of proactively driving toward objectives rather than merely generating isolated responses.
Tool Calling
Tool calling permits an AI model to prompt an external system to execute an action, such as executing a database query, triggering an API call, performing computations, or manipulating files.
Function Calling
Function calling serves as an alternative designation for a comparable mechanism, where a model selects a predefined function and provides the requisite parameters.
AI Orchestration
AI orchestration administers the distinct components of an artificial intelligence infrastructure, managing models, tools, workloads, context data, and agents to ensure synchronized sequencing.
Multi-Agent System
A multi-agent architecture incorporates multiple independent AI agents, each assigned a distinct duty—such as one conducting research, another verifying outcomes, and a third executing the primary assignment.
New AI Protocols
Model Context Protocol (MCP)
MCP supplies AI apps with a standardized method for linking with external data and tools, utilizing MCP servers to grant access to functions, files, databases, and additional assets.
Agent2Agent (A2A)
A2A facilitates communication between discrete AI agents, enabling agents originating from different platforms or networks to divide tasks and exchange results.
A straightforward method for distinguishing between them:
MCP links an AI architecture with tools and data.
A2A links individual AI agents with other AI agents.
AI Safety and Control
Prompt Injection
Prompt injection happens when malicious instructions are embedded within text, documents, web pages, or other inputs, attempting to steer an AI application toward prohibited or dangerous behavior.
AI Evals
AI evaluations, or evals, test how effectively a model or agent executes a designated assignment, quantifying precision, dependability, safety, or other key metrics.
Observability
Observability grants developers transparent insight into internal system operations, detailing model responses, tool activations, system errors, latency, and financial costs.
Human-in-the-Loop (HITL)
HITL maintains human oversight at critical junctures, requiring manual approval before a system executes financial transactions, modifies crucial records, or executes high-stakes choices.

The Bigger Picture
The contemporary AI ecosystem comprises several interconnected layers. Models supply core intelligence, context delivers relevant background data, RAG and retrieval source external knowledge, and tools facilitate active interventions. Agents manage multi-step ambitions, while MCP and A2A bridge separate platforms. Evals and observability allow teams to measure and inspect performance metrics, paired with human oversight and security safeguards to keep systems properly regulated.
This paradigm shift defines contemporary artificial intelligence. Models no longer operate as isolated entities yielding single answers; instead, modern systems access information, wield utilities, execute multi-phase decisions, coordinate with other agents, and function under stringent safety frameworks.
