Understand the key concepts behind AI agents, automation, and modern productivity tools. Learn how GAIA uses these technologies to manage your digital workflow.
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.
Agentic AI describes artificial intelligence systems designed to operate autonomously, making decisions and executing multi-step tasks with minimal human oversight.
Proactive AI is AI that acts before you ask: it watches for events (a new email, an upcoming meeting, a deadline), decides when something needs attention, and starts the work or alerts you on its own. Reactive AI is the opposite: it does nothing until you send a prompt or a command, and then it responds.
Graph-based memory is an AI memory architecture that stores information as interconnected nodes and relationships, enabling rich contextual understanding and persistent knowledge across interactions.
Semantic search is a search technique that understands the meaning and intent behind a query, returning results based on conceptual relevance rather than exact keyword matches.
A Large Language Model (LLM) is an artificial intelligence model trained on vast amounts of text data that can understand, generate, and reason about human language with remarkable fluency.
Context awareness in AI is the ability to understand the full situation surrounding a task or interaction, including who is involved, what has happened before, related projects, deadlines, and the user's preferences and patterns.
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.
A transformer is a neural network architecture introduced in 2017 that uses self-attention mechanisms to process sequences of data in parallel, forming the foundation of all modern large language models.
Fine-tuning is the process of taking a pre-trained AI model and continuing its training on a smaller, task-specific dataset to adapt its behavior for a particular domain or application.
Embeddings are dense numerical vector representations of data, such as text, images, or audio, that capture semantic meaning and relationships in a high-dimensional space.
A vector database is a database system designed to store, index, and query high-dimensional vector embeddings at scale, enabling fast similarity search across large collections of embedded data.
Retrieval-Augmented Generation (RAG) is a technique that enhances LLM responses by first retrieving relevant documents or data from an external knowledge base and injecting that context into the model's prompt.
Prompt engineering is the practice of designing and refining inputs to AI language models to reliably elicit desired outputs, shaping model behavior without modifying the underlying weights.
Zero-shot learning is the ability of an AI model to perform tasks it has never explicitly been trained on, relying on general knowledge and reasoning rather than task-specific examples.
Few-shot learning is the ability of an AI model to adapt to a new task or output format from just a small number of input-output examples provided in the prompt, without any weight updates.
Chain-of-thought (CoT) reasoning is a prompting technique that instructs an AI model to articulate its intermediate reasoning steps before producing a final answer, significantly improving accuracy on complex multi-step problems.
AI hallucination is the phenomenon where a language model generates confident-sounding but factually incorrect, fabricated, or nonsensical information that is not grounded in the input or training data.
Tokenization is the process of breaking text into smaller units called tokens, which serve as the basic input units for language models. Tokens typically represent word fragments, whole words, or punctuation.
The context window is the maximum number of tokens a language model can process in a single inference call, encompassing the system prompt, conversation history, retrieved documents, and generated output.
A neural network is a computational model inspired by biological neural systems, consisting of interconnected layers of nodes that learn to transform input data into outputs by adjusting connection weights during training.
Natural Language Processing (NLP) is a branch of artificial intelligence that focuses on enabling computers to understand, interpret, generate, and respond to human language in a meaningful way.

Inference is the process of running a trained AI model on new input data to generate predictions, responses, or decisions, as opposed to training, which is the process of building the model from data.
AI alignment is the field of research and engineering focused on ensuring that AI systems pursue goals that are beneficial, safe, and consistent with human values and intentions, even as they become more capable and autonomous.
Tool use is the capability of AI agents to invoke external functions, APIs, databases, and services to retrieve information or take actions in the real world beyond generating text.
Function calling is a feature of AI models that allows them to generate structured, machine-readable invocations of predefined functions, enabling AI systems to reliably call external APIs and tools with the correct arguments.

Orchestration in AI refers to the systematic coordination of multiple agents, models, tools, and data sources to execute complex multi-step tasks with managed dependencies, state, and error handling.
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.
Temperature is a parameter in language model inference that controls the randomness of token selection — higher temperatures produce more varied and creative outputs, while lower temperatures produce more consistent and deterministic responses.
A system prompt is a set of instructions provided to a language model at the beginning of a session that defines its persona, constraints, tone, and behavioral guidelines before any user interaction begins.
Structured output is a technique that constrains an LLM to respond in a predefined format — typically JSON or XML — enabling reliable programmatic parsing of model responses rather than free-form text.
Guardrails are safety constraints applied to AI systems that limit, filter, or redirect model outputs to prevent harmful, incorrect, or undesired behavior while allowing beneficial use.
An agent loop is the iterative execution cycle of an AI agent in which it reasons about the current state, selects and executes an action (often a tool call), observes the result, and repeats until the task is complete or a stopping condition is reached.
A supervisor agent is the AI agent in charge of a multi-agent system. It receives the request, splits it into subtasks, hands each one to a specialized worker agent (a subagent) with the right tools, checks what comes back, and combines the results into one answer. The workers do the execution; the supervisor decides who does what and when the job is done.
A subagent is an AI agent that another agent starts to handle one part of a bigger task. The parent agent (often called the supervisor or orchestrator) gives it a written task, a focused set of tools and a fresh context of its own; the subagent works on that piece independently and returns only its result. Splitting work this way lets several subagents run in parallel and keeps the main agent's context clean.
Parallel agents are multiple AI agents that execute concurrently on independent tasks, combining their results to complete complex workflows faster than sequential single-agent processing would allow.
Agent state is the structured data that an AI agent maintains throughout the execution of a task, tracking what has been done, what has been learned, and what steps remain — enabling multi-step reasoning without repeating work.
Prompt chaining is a technique where the output of one LLM prompt is used as the input for the next, creating a sequence of connected calls that collectively accomplish a complex task no single prompt could reliably achieve.
Semantic routing is the practice of classifying user input by its semantic meaning and intent to direct it to the appropriate handler, agent, or response strategy — enabling a single AI interface to manage diverse types of requests intelligently.
A local LLM is a large language model that runs entirely on your own hardware — a laptop, workstation, or self-hosted server — without sending data to external API providers.
Transfer learning in AI is a technique where a model trained on one task reuses what it learned as the starting point for a different but related task, instead of training from scratch. It is the reason large language models are practical: they are pre-trained once on huge amounts of text, then adapted to chat, coding, or a specific domain with a small fraction of the data and compute.
Reinforcement learning (RL) is a machine learning paradigm in which an agent learns to make decisions by receiving reward signals for actions that achieve desired outcomes and penalty signals for undesired ones.
Intent recognition is the process by which an AI system identifies the underlying goal or purpose of a user's input, enabling it to select the appropriate response or action rather than responding only to surface-level phrasing.
Entity extraction is the NLP process of identifying and classifying specific pieces of information — such as people, organizations, dates, locations, and tasks — within unstructured text.
Named entity recognition (NER) is a natural language processing task that identifies and classifies named entities in text into predefined categories such as persons, organizations, locations, dates, and domain-specific entities.
Sentiment analysis is the use of natural language processing (NLP) and AI to identify the emotional tone of a piece of text and label it, usually as positive, negative, or neutral, sometimes with a score for how strong the feeling is or a finer label such as frustrated, excited, or urgent.
Speech-to-text (STT), also called automatic speech recognition (ASR), is AI technology that converts spoken audio into written text: you talk, and the software writes down what you said. It powers phone dictation, live captions, voice assistants and voice chatbots, and it is the first step whenever an AI system has to understand speech.
Text-to-speech (TTS) is the technology that converts written text into synthesized spoken audio, enabling computers and AI systems to communicate verbally through natural-sounding voices.

A reasoning model is an AI language model specifically optimized to think through problems step-by-step using extended internal deliberation before producing a final answer, achieving higher accuracy on complex reasoning tasks.
Reinforcement Learning from Human Feedback (RLHF) is a machine learning technique that trains AI models to produce outputs preferred by humans by learning from human-provided rankings or ratings rather than purely from raw data.
Constitutional AI (CAI) is a training methodology developed by Anthropic that aligns AI models with human values by having the AI evaluate and revise its own outputs against a written set of principles — a 'constitution' — rather than relying exclusively on human-labeled preference data.
In AI, a token is the basic unit of text that language models process — roughly equivalent to 4 characters or ¾ of an average English word. Tokens are used to measure context window capacity and determine API usage costs.
A chatbot is software that talks with you: it answers questions in a chat window using scripted rules or a language model. The difference between a chatbot and an AI assistant is action. A chatbot replies; an AI assistant (often called a virtual or digital assistant) also does the work, such as sending the email, booking the meeting or creating the task, in the tools you already use.
An AI assistant is AI that helps a person on request: you ask, it answers or carries out the task, and you stay in the loop. An AI agent is AI that is given a goal and works toward it by itself, deciding which steps to take and which tools to use along the way. Most capable AI assistants today are built on agents underneath.
An AI assistant is software that understands requests in plain language and then acts on them: it answers questions, but it also drafts and sends email, schedules meetings, tracks tasks and runs multi-step workflows inside the apps you already use. Siri, Alexa, Google Assistant, ChatGPT and GAIA are all AI assistants; what separates them is how much real work each one can do on your behalf.
