IntermediateAn always-on agent is an AI assistant that runs on a provider's servers and starts by itself at a set time or when something happens, even while your computer is off.
BeginnerInformation agents are AI assistants in Google Search that follow a topic for you and send a summary when something changes; Google announced them in May 2026.
IntermediateA managed agent is an AI agent that runs on the AI provider's servers: you describe the task, tools and rules, and the provider handles the computer and the access keys.
IntermediateIn a multi-agent system several AI agents share one task, each doing its own part, which helps with large tasks that split into pieces and costs more to run.
AdvancedSelf-evolving agentic models are AI agents that learn from their own work: they change their notes, tools, code or training data and test whether that helps.
IntermediateAI orchestration connects several AI steps, such as recognising a question, searching your documents and writing an answer, into one process that runs in the right order.
IntermediateBinex is a free, open-source tool from one developer that runs a chain of AI steps on your own computer and records what each step received, produced and cost.
IntermediateCoDream lets a team of AI agents learn from a failed task: they discuss what went wrong and pass the lesson to the teammates who are weakest at that kind of task.
IntermediateGalactic is an open-source Mac app by one developer that lets several AI coding assistants work on the same project at once, each in its own copy of the code.
IntermediateITBench-AA is a test from May 2026 in which AI agents must find the cause of IT outages in Kubernetes systems; at launch the best model scored 47%.
IntermediateJobBench is a May 2026 test that scores AI agents on 130 work tasks that professionals most want to hand off; at launch the best agent reached 45.9%.
IntermediateKairos is the codename of an unreleased Claude Code feature, found in leaked code in March 2026, that would tidy up the AI's memory in the background.
BeginnerA chatbot answers your questions in a conversation; an AI agent carries out a task for you in steps, with tools such as your email or order system.
IntermediateAgent evaluation tests whether an AI agent really completes the tasks you give it, such as a refund, by checking both the end result and the steps it took.
BeginnerAgent operational memory is a set of text files with an AI agent's rules and lessons, read at the start of every session so you need not explain them again.
IntermediateAgentic AI is AI that carries out a task on its own: it plans the steps, uses software such as email or an expense system, checks the results and asks when it gets stuck.
IntermediateWith agentic RAG, an AI agent searches in steps: it decides what to look for, checks whether the results answer the question and searches again if they do not.
IntermediateAgentic engineering is building software with AI coding agents that write and test the code, while a developer decides what to build and checks the result.
BeginnerAn AI agent is software that carries out a task on its own: it plans the steps, uses tools such as your email or order system, and asks you when it is unsure.
AdvancedBelief-action decoupling splits an AI agent in two: one part keeps a short list of what it knows and how sure it is, the other picks the next step from that list.
IntermediateContext compression keeps what an AI model has to read short, by summarising or removing old material, so long tasks stay affordable and the model keeps its focus.
AdvancedDynamic cognitive scaffolding means an AI agent works out for each task how to split it into steps, instead of always following the same fixed recipe.
IntermediateFunction calling lets an AI model ask your own software to do something, such as look up an order or check stock, and then answer with the real result.
AdvancedInference-time co-evolution, a research idea from May 2026, lets a team of AI agents improve how it works together while in use, without retraining the AI model.
IntermediatePrompt chaining gives an AI model a task in small steps one after another; each answer is the input for the next, so every step is simpler and easier to check.
AdvancedProof-derived authorization lets an AI agent do a risky action only after independent checks approve a recorded reason, with a temporary key for just that action.
AdvancedTest-time co-evolution, a research idea from May 2026, lets a team of AI agents improve while in use by learning who is good at what, without retraining the model.
IntermediateThe real-world agent reliability gap is the difference between how well AI agents score on popular tests and how reliably they do real work, time after time.
IntermediateTrajectory refinement improves an AI agent's plan by comparing it with what happened when the agent carried it out, and repairing the steps that went wrong.
