Agentic AI and AI agents
The two terms overlap. An AI agent is a single system that runs a loop of deciding, acting and checking. Agentic AI is the wider approach: designing AI systems, from simple workflows to many cooperating agents, that take actions towards a goal rather than only producing a reply.
Autonomy is a dial, not a switch. Anthropic’s guide to building effective agents describes the settings along it:
- Prompt chaining: a task is split into fixed steps, each handled by a model call.
- Routing: an input is classified and sent to the right specialised step.
- Parallelisation: independent parts run at the same time and are combined.
- Orchestrator and workers: a model breaks the task down while it works and delegates the parts.
- Evaluator and optimiser: one model drafts, another checks and asks for changes.
- Agents: the model plans and uses tools on its own until the task is done.
The guide’s advice is to choose the simplest option that works, and to add autonomy only where it pays for itself.
How multi-agent systems work
In a multi-agent system an orchestrator agent receives the goal, makes a plan and hands tasks to specialised agents: one researches, one drafts, one reviews. Each has its own instructions, tools and context, so it can focus on one job. The orchestrator collects the results, resolves conflicts and decides what happens next.
The design has clear benefits: parallel work on large tasks, a separation between the agent that does and the agent that checks, and shorter, clearer instructions for each part. It also has costs: more model calls and therefore more spend, more time per task and more places where things can go wrong. A single agent is often enough. Several agents earn their place when a task splits naturally into parts.
People stay in the loop at defined points: approving the plan, signing off before anything is sent, paid or changed, and reviewing a sample of finished work.
Examples of agentic AI in companies
- Bid responses: one agent pulls the requirements from the tender, another drafts answers from past proposals, a third checks them against the requirements.
- Due diligence: agents read a data room in parallel, extract issues by topic and assemble a report for the deal team.
- Month-end support: agents reconcile accounts, explain variances and prepare a pack for the controller.
- Software changes: coding agents such as Claude Code plan a change, edit the code, run the tests and open a pull request for review.
What the research says
- Gartner expects 40% of enterprise applications to include task-specific AI agents by the end of 2026, up from less than 5% in 2025.
- Gartner also expects over 40% of agentic AI projects to be cancelled by the end of 2027, because of rising costs, unclear business value or inadequate risk controls.
- In McKinsey’s State of AI 2026 survey, about two in ten respondents said their organisation had reached the scaling phase with AI agents.
Read together, the figures point the same way: the technology is arriving quickly, and the projects that last have a measurable goal and proper controls from the start.
