The building blocks every other AI term sits on.
The broad field of building computer systems that perform tasks normally associated with human intelligence, such as understanding language, recognising images, or making decisions. Every other term in this catalogue sits somewhere under this umbrella.
ExampleML, deep learning and LLMs are all subsets of AI.
A branch of AI where systems learn patterns from data instead of following hand-written rules. The more good examples they see, the better their predictions get.
ExampleA spam filter that learns from millions of emails labelled 'spam' or 'not spam'.
Machine learning using neural networks with many layers. It powers modern speech recognition, image generation and language models.
ExampleWhy your phone transcribes voice notes accurately.
A computing structure loosely inspired by the brain: layers of connected 'neurons' that pass numbers to each other. Training adjusts the strength of every connection until the network produces useful outputs.
ExampleMillions of tiny dials tuned until the answer comes out right.
AI that creates new content, such as text, images, audio, video or code, rather than only classifying or predicting. ChatGPT, Claude, Gemini and Midjourney are all generative AI.
ExampleTraditional AI: 'Is this a cat?' GenAI: 'Draw me a cat.'
AI that classifies, scores or forecasts from data rather than generating new content. It still runs most fraud detection, recommendations and demand forecasting.
ExampleA bank model scoring a loan application's risk.
Training a model on examples that come with the correct answer (labels). The model learns to map inputs to the right outputs.
ExamplePhotos labelled 'dog' or 'cat' teach an image classifier.
Training on data without labels so the model discovers structure on its own, such as clusters or patterns. Useful when labelling is too expensive.
ExampleGrouping customers into segments by buying behaviour.
Learning where the data provides its own labels, for example hiding a word and predicting it. This is how LLMs learn from raw internet text without human labelling.
ExamplePredict the next word, billions of times.
Training by trial and error: an agent takes actions, receives rewards or penalties, and learns a strategy that maximises reward. It is now central to training reasoning models and agents.
ExampleAlphaGo learning to beat world champions at Go.
The expensive phase where a model learns from large amounts of data by repeatedly adjusting its weights to reduce errors. Frontier model training runs cost hundreds of millions of dollars in compute.
ExampleYears of medical school for a model.
Using a trained model to produce an output for a new input. Every chat message you send triggers inference, and inference is now the bulk of AI's ongoing cost.
ExampleThe trained doctor seeing a patient.
The internal numbers a model learns during training. Parameter count (e.g. '8B', '70B') is a rough indicator of a model's size and capacity.
ExampleA 70B model holds about 70 billion learned numbers.
The collection of examples used to train or test a model. Data quality, diversity and licensing matter as much as model design.
ExampleCommon Crawl, a huge scrape of the public web.
When a model memorises its training data instead of learning general patterns, so it performs well in training but poorly on new data.
ExampleA student who memorised past papers but fails new questions.
A formula that measures how wrong a model's predictions are. Training is the process of pushing this number down.
ExampleValidation loss dropping means the model is learning.
The core algorithms of training: backpropagation works out how each weight contributed to the error, and gradient descent nudges every weight in the direction that reduces it.
ExampleWalking downhill in fog, one small step at a time.
A precise set of steps for solving a problem. In AI, it usually refers to the learning method or the procedure a model follows.
ExampleThe recipe, not the cake.
The trained artefact that takes an input and produces an output: architecture plus learned weights. When people say 'the AI', they usually mean the model.
ExampleGPT, Claude and Llama are model families.
The field of AI concerned with understanding and generating human language. LLMs are the current state of the art in NLP.
ExampleTranslation, sentiment analysis, chatbots.
The field of AI that lets machines interpret images and video, including detecting objects, reading text and recognising faces.
ExampleSelf-checkout cameras identifying produce.
Starting from a model already trained on one task and adapting it to a related task, instead of training from scratch. Fine-tuning is a form of transfer learning.
ExampleAn English-trained model adapted for legal English.
Training data generated by AI or simulation rather than collected from the real world. It fills gaps where real data is scarce, private or expensive.
ExampleFrontier labs use model-written maths problems to train reasoning.
Humans tagging data with the correct answers so models can learn from it. A large global workforce does this, increasingly for expert-level tasks.
ExampleDoctors rating model answers to medical questions.
The empirical finding that model performance improves predictably as you increase compute, data and parameters. It justified the race to build ever-larger models.
Example10x more compute gives a measurable, predictable gain.
Capabilities that appear in larger models but not in smaller ones, seemingly without being specifically trained, such as multi-step arithmetic. Researchers still debate how 'sudden' they really are.
ExampleSmall models can't do it; big ones suddenly can.
Describes a model whose internal reasoning can't easily be inspected or explained. Most deep learning models are black boxes to some degree.
ExampleIt gives the right answer but can't show why.
The engines behind ChatGPT, Claude, Gemini and every AI product.
An AI model trained on enormous amounts of text to predict the next token. At scale, that simple objective produces models that can write, summarise, translate, code and reason.
ExampleGPT, Claude, Gemini, Llama, Qwen, Mistral.
The neural-network architecture, introduced by Google in 2017 ('Attention Is All You Need'), that almost every modern LLM is built on. Its key mechanism, attention, lets the model weigh which parts of the input matter most to each other.
ExampleThe 'T' in GPT.
The mechanism inside transformers that lets every token 'look at' every other token and decide how relevant it is. It's why models can connect a pronoun to a noun many sentences earlier.
ExampleWorking out that 'it' refers to 'the bank', not 'the river'.
OpenAI's family of LLMs and the acronym that describes the recipe: generate text, pre-train on huge data, use the transformer architecture. It is often used loosely to mean any chatbot model.
ExampleChatGPT runs on GPT models.
A large, general-purpose model trained on broad data that can be adapted to many downstream tasks. Most AI products are built on top of a handful of foundation models.
ExampleOne base model powering a legal bot, a tutor and a coding tool.
The most capable models available at any given time, typically from labs like OpenAI, Anthropic, Google DeepMind, xAI and Meta, plus leading Chinese labs. Regulators use the term for models above certain capability or compute thresholds.
ExampleEach new flagship release resets the frontier.
A company training the most advanced AI models, needing billions of dollars of compute. The term separates model builders from companies that build on top of their models.
ExampleOpenAI, Anthropic, Google DeepMind, xAI, Meta, DeepSeek.
A model that can understand or generate more than one type of data, such as text, images, audio and video, within one system.
ExamplePhotograph a broken appliance and ask how to fix it.
A model (also called a Large Reasoning Model) trained with reinforcement learning to think through a problem in hidden steps before answering. Slower and costlier, but much stronger at maths, code and multi-step problems.
ExampleThe 'Thinking…' indicator in AI apps.
A compact model, typically under ~15B parameters, cheap and fast enough to run on laptops, phones or edge devices. Often fine-tuned for one narrow job.
ExamplePhi, Gemma and small Llama/Qwen variants.
A model whose trained weights are published so anyone can download, run and fine-tune it, though the training data and code may stay private. Different from fully 'open source' AI.
ExampleLlama, Qwen, DeepSeek, Mistral, gpt-oss.
A model available only through its maker's app or API; the weights are never released. Usually the most capable, but you depend on the vendor.
ExampleGPT, Claude and Gemini flagship models.
AI released with weights, code and ideally training-data details under a licence that allows use, study, modification and sharing. The Open Source Initiative publishes a formal definition that most 'open' models don't fully meet.
ExampleOpen-weight is not automatically open source.
An architecture that splits a model into many specialised sub-networks ('experts') and activates only a few for each token. You get the knowledge of a huge model at the running cost of a smaller one.
ExampleA 600B-parameter model that only uses ~40B per token.
A generative model that learns to turn random noise into an image, video or audio by reversing a gradual noising process. It powers most image and video generators.
ExampleStable Diffusion, Midjourney, video models.
A language model that generates text by refining a whole block of tokens in parallel, diffusion-style, instead of one token at a time. It promises much faster generation.
ExampleText appearing as a rough draft that sharpens all at once.
Two networks trained against each other: a generator makes fakes and a discriminator tries to spot them, each improving the other. It was the leading image generator before diffusion models.
ExampleThe tech behind early deepfakes.
An encoder turns input into an internal representation; a decoder generates output from it. Most chat LLMs are 'decoder-only', while models like BERT are encoder-only.
ExampleTranslation models use both.
Google's 2018 encoder-only transformer, designed to understand text rather than generate it. Its descendants still power search ranking and classification.
ExampleUsed to power Google Search understanding.
An alternative to transformers that processes long sequences more efficiently by keeping a compact running state. Often combined with attention in 'hybrid' architectures.
ExampleHandling very long inputs at lower cost.
Models that loop an input through their internal layers multiple times to 'think' in hidden vectors instead of writing out reasoning in words. It can boost capability but makes reasoning harder to inspect.
ExampleThinking silently instead of thinking out loud.
A hypothetical internal 'language' that models might reason in, made of vectors rather than human words. Safety researchers worry it would make AI reasoning unreadable to humans.
ExampleThe opposite of a readable chain of thought.
An approach where a model breaks a very long input or task into pieces and calls itself (or sub-models) recursively on each part. It works around context-window limits.
ExampleReading a 10,000-page archive by delegating chapters to itself.
A model that learns how an environment works (physics, cause and effect) so it can simulate and predict what happens next. Seen as key for robotics, games and more general intelligence.
ExampleGenerating an explorable 3D world from a prompt.
A model that understands images and text together, for example answering questions about a photo, chart or screenshot.
ExampleReading a receipt and totalling it.
A model that takes in vision and language and outputs physical actions, used to control robots.
Example'Pick up the red cup' turned into arm movements.
A model that converts text, images or other data into vectors (embeddings) that capture meaning. It is the backbone of semantic search and RAG.
ExampleTurning every support article into a searchable vector.
A base model only continues text; an instruct (or chat) model has been further trained to follow instructions and hold a conversation. Most apps use instruct models.
ExampleBase: finishes your sentence. Instruct: answers your question.
A document published with a model describing what it is for, how it was trained and evaluated, and its limitations and risks.
ExampleThe nutrition label for a model.
A detailed safety and capability report released by a lab alongside a major model, covering red-teaming, dangerous-capability tests and mitigations.
ExamplePublished with every flagship frontier release.
The date after which a model has no training data, so it doesn't know about later events unless given tools like web search.
ExampleAsking about last week's news without search.
Degradation that happens when models are trained repeatedly on AI-generated content, losing diversity and accuracy over generations.
ExampleA photocopy of a photocopy of a photocopy.
What you'll meet the moment you use or build with a model.
The chunks of text a model actually reads and writes, often a word, part of a word or punctuation. Pricing, speed and limits are all measured in tokens.
ExampleRoughly 1 token ≈ ¾ of an English word.
The component that splits text into tokens and maps them to numbers. Different models use different tokenizers, which is why token counts vary.
ExampleHindi text often uses more tokens than English.
The maximum amount of text (in tokens) a model can consider at once, including instructions, documents, conversation history and its own answer.
ExampleThe model's short-term working memory.
The drop in a model's accuracy as its context window fills with long or noisy content, even when it's under the limit. It's why bigger windows don't automatically mean better answers.
ExampleAn agent forgetting early instructions 200 steps in.
A conversational interface to an AI model. Modern chatbots are powered by LLMs and increasingly can use tools and take actions.
ExampleChatGPT, Claude, Gemini, Meta AI.
An AI built into a product to help you with tasks as you work, rather than acting fully on its own. 'Copilot' is also Microsoft's brand for its assistants.
ExampleDrafting an email inside your inbox.
A setting that controls how random a model's output is. Low temperature gives focused, repeatable answers; high temperature gives varied, creative ones.
Example0.1 for extraction, 0.9 for brainstorming.
Settings that limit which candidate tokens the model can choose from, trimming unlikely options. Used together with temperature to control creativity.
ExampleOnly picking from the top 90% most likely words.
When an AI confidently produces false or invented information, such as fake facts, citations or numbers. It happens because models generate plausible text, not verified truth.
ExampleA chatbot citing a court case that never existed.
Tying a model's answers to verifiable sources, such as your documents, a database or web search, to reduce hallucination.
ExampleAnswers that cite the exact policy paragraph.
Forcing a model to reply in a strict machine-readable format, like JSON matching a schema, so software can use the result reliably.
ExampleExtracting {name, email, amount} from invoices.
Sending a model's response token by token as it's generated, so users see text appear immediately instead of waiting for the full answer.
ExampleThe typing effect in chat apps.
Latency is how long a response takes; TTFT (time to first token) is how quickly the first word appears. Both matter hugely for voice and real-time apps.
ExampleVoice agents need sub-second TTFT.
How fast a model generates output, and how much total work a system can serve at once. Faster throughput means snappier apps and lower cost.
ExampleSpecialised chips serving 1,000+ tokens/sec.
The way software talks to other software. AI companies sell model access via APIs, charged per token.
ExampleYour app sends a prompt to an API and gets text back.
A cap on how many requests or tokens you can send to an API per minute or day. Hitting it causes errors in production apps.
Example429: Too Many Requests.
Automatically sending each request to the most suitable model, e.g. cheap and fast for easy questions, powerful for hard ones, to balance cost and quality.
ExampleSimple FAQ → small model; legal analysis → frontier model.
A setting that controls how much a reasoning model 'thinks' before answering. More thinking improves hard answers but costs more time and tokens.
ExampleLow effort for chat, high effort for debugging.
Spending more compute when the model is answering (not training), for example longer reasoning or trying multiple answers, to get better results.
ExampleLetting the model think for minutes on a hard maths problem.
Reusing the processed version of a repeated prompt prefix (like long instructions or documents) so later requests are faster and much cheaper.
ExampleCached input tokens often cost ~90% less.
Sending many requests to be processed asynchronously, usually within 24 hours, at a large discount. Ideal for non-urgent bulk jobs.
ExampleClassifying 1 million reviews overnight at half price.
An AI mode that autonomously runs many web searches, reads sources and produces a long cited report over several minutes.
ExampleA 20-page market analysis with 80 citations.
Search that returns a synthesised AI answer with citations instead of a list of links.
ExamplePerplexity, Google AI Mode, ChatGPT search.
A model's tendency to agree with or flatter the user rather than give an honest answer. Labs actively train against it.
ExamplePraising a flawed business plan because you seem excited.
Side-panel workspaces in chat apps where the AI creates and edits documents, code or apps you can see and interact with alongside the conversation.
ExampleBuilding a small web app inside the chat.
Saved configurations of a chatbot with your own instructions, files and tools, reusable for a specific job.
ExampleA 'Proposal Writer' bot loaded with your templates.
How we talk to models, and how we decide what they see.
The input you give an AI model: a question, instruction, examples or context. The quality of the output depends heavily on the quality of the prompt.
Example'Summarise this for a CFO in 5 bullets' beats 'summarise this'.
High-priority instructions set by the app builder that define the model's role, tone and rules before the user says anything.
Example'You are a support agent for Acme. Never discuss pricing.'
Designing and refining prompts to get reliable, high-quality outputs, using clear roles, examples, constraints and output formats.
ExampleIterating on a prompt like you iterate on code.
Deciding exactly what information goes into the model's context (instructions, retrieved documents, tool results, memory) and in what order. It has largely replaced 'prompt engineering' as the core skill for building agents.
ExampleNot just 'what do I ask?' but 'what does the model need to see?'
Asking a model to perform a task with no examples, relying on what it already knows.
Example'Classify this review as positive or negative.'
Including a handful of worked examples in the prompt so the model copies the pattern and format.
ExampleShow 3 tweets in your brand voice, then ask for a 4th.
A model's ability to learn a new task from instructions and examples in the prompt alone, without any retraining.
ExampleTeaching a new invoice format with two samples.
Prompting or training a model to reason step by step before answering, which improves accuracy on logic and maths.
Example'Let's think step by step.'
Having a model explore several reasoning paths in parallel, evaluate them and pursue the most promising, like searching a decision tree.
ExampleTrying three solution strategies and picking the best.
Generating several independent answers and choosing the most common one, which reduces random reasoning errors.
ExampleAsk 5 times, take the majority answer.
A foundational agent pattern where the model alternates between reasoning about what to do, taking an action (tool call) and observing the result.
ExampleThink → search → read → think → answer.
Assigning the model a persona or expertise to shape its tone and focus.
Example'You are a senior tax accountant in India…'
Breaking a task into a sequence of prompts where each step's output feeds the next, which gives more control than one giant prompt.
ExampleOutline → draft → edit → format.
Using an AI model to write, critique or improve prompts for another model (or itself).
Example'Rewrite this prompt so a smaller model follows it reliably.'
A reusable prompt with placeholders filled in at runtime, so the same well-tested instructions work for many inputs.
Example'Write a product description for {product} aimed at {audience}.'
In image generation, a list of things you don't want in the output.
Example'blurry, extra fingers, watermark'.
Automatically summarising or pruning older parts of a long conversation or agent run so it fits in the context window without losing key facts.
ExampleAn agent summarising its first 100 steps into a short note.
Techniques for deciding what stays in context, what gets summarised, and what gets stored outside for later retrieval during long tasks.
ExampleKeeping the task plan pinned, trimming old tool logs.
The rule that models should prioritise system/developer instructions over user messages, and user messages over content found in documents or tool results. It's a key defence against prompt injection.
ExampleA web page can't override the developer's rules.
A shared, organised collection of tested prompts that a team reuses.
ExampleA company's approved prompts for sales emails.
How models learn, and how they're shaped after pre-training.
The first, most expensive training stage, where a model learns language and world knowledge by predicting the next token across trillions of tokens of text.
ExampleReading most of the internet.
Everything done after pre-training to make a model useful and safe: instruction tuning, RLHF, reasoning RL, safety training. It's now where much of the capability gain comes from.
ExampleTurning a raw text predictor into a helpful assistant.
Further training an existing model on a smaller, specialised dataset so it learns a particular style, format or domain. Use fine-tuning to change behaviour; use RAG to change knowledge.
ExampleTuning a model to write in your support team's tone.
Fine-tuning on example prompt/response pairs written or approved by humans, teaching the model the desired answers directly.
Example10,000 ideal customer-support replies.
Fine-tuning a base model on many instruction-following examples so it responds helpfully to requests.
ExampleWhat turns a base model into a chat model.
Humans compare model outputs, a reward model learns their preferences, and the LLM is trained to produce responses people prefer. It made chatbots helpful and polite.
ExampleRating two answers: which is better?
Using AI feedback guided by a written set of principles (a 'constitution') instead of relying only on human ratings. Pioneered by Anthropic.
ExampleA model critiquing its own answer against its principles.
A simpler alternative to RLHF that trains directly on pairs of preferred vs rejected answers, without a separate reward model.
ExampleCheaper preference tuning for open models.
Reinforcement learning where the reward comes from automatically checkable outcomes, such as a correct maths answer or passing tests. It's the main recipe behind reasoning models.
ExampleReward = 1 if the code passes the unit tests.
Group Relative Policy Optimization: an efficient RL algorithm, popularised by DeepSeek, that scores a group of sampled answers against each other instead of using a separate value model.
ExampleUsed to train DeepSeek-R1.
A model trained to score outputs by quality or preference, used as the 'judge' during reinforcement learning.
ExamplePredicting which answer a human would prefer.
When a model finds a loophole to maximise its reward without actually doing the intended task.
ExampleAn agent editing the tests so they pass.
A simulated workspace (a codebase, browser, spreadsheet, company app) where an agent practises tasks and gets rewarded, used to train agentic skills. Building them is a fast-growing business.
ExampleA fake CRM where agents learn to process refunds.
An efficient fine-tuning method that trains a small set of add-on weights instead of the whole model, making customisation possible on a single GPU.
ExampleA plug-in adapter rather than a rebuilt model.
LoRA applied to a quantized (compressed) model, cutting memory needs further so large models can be fine-tuned on consumer hardware.
ExampleFine-tuning a 70B model on one GPU.
The family of techniques, including LoRA and adapters, that fine-tune only a small fraction of a model's parameters.
ExampleHugging Face's PEFT library.
Training a smaller 'student' model to imitate a larger 'teacher', keeping much of the quality at a fraction of the cost.
ExampleHow many 'mini' and 'flash' models are made.
Letting a model keep learning from new experience after deployment without forgetting old skills. Widely seen as a missing piece on the road to more general AI.
ExampleAn assistant that genuinely improves from each week's work.
When training a model on new data makes it lose previously learned abilities.
ExampleFine-tuning on legal text degrades its coding.
Core training settings: an epoch is one pass over the data, a batch is the chunk processed at once, and the learning rate is how big each weight update is.
ExampleToo high a learning rate and training blows up.
A saved snapshot of a model's weights at a point in training, which can be resumed, evaluated or released.
ExampleReleasing an intermediate checkpoint for research.
When test or benchmark questions leak into training data, making a model look better than it really is.
ExampleA model that has 'seen the exam paper'.
Combining the weights of two or more fine-tuned models into one that inherits skills from each, without further training.
ExampleMerging a coding model and a chat model.
Giving models your data so answers are grounded and current.
The system first retrieves relevant information from your documents or data, then passes it to the LLM to write a grounded answer. It reduces hallucination and keeps answers current without retraining.
ExampleAn open-book exam instead of answering from memory.
Numeric vectors that capture the meaning of text, images or other data. Similar meanings end up close together, which enables semantic search.
Example'Car' and 'automobile' get nearly identical vectors.
A database built to store embeddings and quickly find the most similar ones. It's the retrieval layer in most RAG systems.
ExamplePinecone, Weaviate, Qdrant, Chroma, pgvector.
Search by meaning rather than exact keywords, powered by embeddings.
ExampleSearching 'leave policy' finds 'vacation rules'.
Classic search that ranks documents by matching words. Still excellent for exact terms like product codes and names.
ExampleFinding 'SKU-4471' exactly.
Combining keyword and semantic search to get the precision of one and the understanding of the other.
ExampleMost production RAG uses hybrid search.
Splitting long documents into smaller pieces before embedding so the most relevant sections can be retrieved. Chunk size and overlap strongly affect RAG quality.
ExampleBreaking a 200-page manual into ~500-token sections.
A second pass that uses a more precise model to reorder retrieved results so the best matches come first.
ExampleRetrieve 50 chunks, re-rank, keep the top 5.
RAG where an agent decides how to search: rewriting queries, choosing sources, retrieving repeatedly and checking whether results answer the question.
ExampleA research assistant who keeps digging until confident.
RAG that builds a knowledge graph of entities and relationships from your documents and retrieves along those connections, which is good for 'big picture' questions.
Example'How are these 40 suppliers connected to the delay?'
A network of entities (people, products, places) and the relationships between them, stored in a structured way.
ExampleGoogle's info panels are powered by one.
Having a model rephrase or expand a user's question before searching so retrieval finds better results.
Example'That thing from last quarter' → 'Q2 2026 revenue report'.
Generating a hypothetical answer first, then searching for real documents similar to it, which often retrieves better than the raw question.
ExampleImagine the ideal answer, then find what matches it.
Adding a short description of where each chunk fits in its document before embedding it, so chunks don't lose their meaning out of context.
ExampleTagging a chunk: 'From Acme's 2026 refund policy, section 3'.
Instead of retrieving at query time, preloading an entire (small enough) knowledge base into a cached long context, trading retrieval complexity for context cost.
ExampleLoading the whole 100-page handbook once and caching it.
Extracting clean text, tables and structure from PDFs, scans and images so they can be used by AI. Often the hardest part of RAG.
ExampleTurning scanned invoices into structured data.
Showing which source each part of an AI answer came from so users can verify it.
ExampleFootnotes linking to the exact paragraph.
The ongoing trade-off between stuffing everything into a huge context window and retrieving only what's relevant. Most real systems combine both.
ExampleRAG for 10 million docs; long context for one contract.
A business-friendly definition of your data (what 'revenue' or 'active customer' means) that lets AI query databases accurately.
ExampleStopping an AI from inventing its own revenue formula.
Turning a natural-language question into a database query and running it.
Example'Top 10 customers by sales last month' → SQL.
The fastest-moving area: models that don't just answer, but act.
An AI system that pursues a goal on its own: it plans steps, uses tools, observes results and adjusts until the task is done. An LLM answers; an agent acts.
Example'Book the cheapest flight to Goa next Friday', and it actually books it.
The broad category of AI systems that act autonomously toward goals, rather than just responding to prompts. Also used loosely as a marketing label.
ExampleFrom chatbots that talk to agents that do.
An LLM's ability to decide when to call an external function or API (search, calculator, database, email) and use the result. It's the basic mechanism that turns a chatbot into an agent.
ExampleThe model outputs get_weather(city='Delhi') and your code runs it.
The core cycle every agent runs: think, act (call a tool), observe the result, repeat until done or stopped.
ExampleThe while-loop at the heart of every agent.
A process where an LLM works through a defined sequence of steps, such as plan, draft, critique and revise, instead of answering in one shot. More predictable than a fully autonomous agent.
ExampleGenerator → Critic → Human review → Publish.
A key design choice: workflows follow predefined code paths with LLM steps; agents decide their own path dynamically. Start with workflows, and add autonomy only where needed.
ExampleInvoice processing = workflow; open-ended research = agent.
An agent's ability to break a goal into ordered sub-tasks before acting, and to revise the plan as it learns more.
ExampleA to-do list the agent writes for itself.
An agent reviewing its own output, finding problems and trying again before returning a result.
Example'Check your answer for errors, then fix them.'
Several specialised agents working together, each with its own role, coordinated by a supervisor or a shared workflow.
ExampleResearcher, writer and reviewer agents on one report.
An agent that splits a task, delegates parts to other agents, and combines their results.
ExampleA project-manager agent running a team of worker agents.
A helper agent spawned by a main agent to handle one isolated part of a task in its own clean context, then report back.
ExampleSpinning up a sub-agent to search 50 files.
How an agent retains information. Short-term memory is the current context; long-term memory stores facts, preferences and past lessons across sessions.
ExampleAn assistant that remembers you prefer window seats.
The problem that most agents start each session with no memory of previous ones, repeating mistakes and re-asking questions.
ExampleExplaining your codebase to the agent again every morning.
Designing AI systems so a person reviews or approves key decisions before they take effect. Essential for payments, publishing and sending messages.
ExampleThe agent drafts the post; you click 'Approve'.
A lighter form of oversight where the agent acts on its own but a human monitors and can intervene or roll back.
ExampleReviewing a dashboard of what the agent did today.
A scale describing how independently an agent may act, from suggest-only, to act-with-approval, to fully autonomous.
ExampleLike self-driving levels, but for software agents.
Tasks that take an agent many steps, hours or days to complete. How long an agent can work reliably is now a headline capability measure.
ExampleMigrating a whole codebase to a new framework.
When an agent gradually stops following instructions or wanders off-task over many steps.
ExampleStep 300: the agent has forgotten the original goal.
An agent that operates a computer like a person: seeing the screen, moving the mouse, clicking and typing across any app.
ExampleFilling a form in legacy software with no API.
An agent that navigates websites in a browser to complete tasks: searching, clicking, filling forms and extracting data.
ExampleComparing prices across five sites and ordering the cheapest.
An agent that autonomously writes, runs, tests and fixes code across a whole project, not just autocompleting lines.
ExampleClaude Code, OpenAI Codex, Cursor agent, Devin.
An AI agent you talk to in real time by phone or voice, able to listen, respond naturally and take actions.
ExampleAn AI receptionist booking clinic appointments.
An agent that runs continuously or on a schedule without being prompted, watching for events and acting on them.
ExampleAn agent that triages your inbox every morning.
A consumer agent that manages your schedule, email, research and errands across your apps.
Example'Reschedule my dentist and tell my team I'm out Friday.'
An agent built for one industry or job, with domain data and tools, such as legal, healthcare, accounting or recruiting.
ExampleAn AI paralegal reviewing contracts.
