Loops

Also written: Agentic loops, Agent loops

AI systems that repeatedly perform a task, analyze results, and refine their approach.

In plain terms

Loops in AI mean a system keeps trying something, learning from it, and trying again to get better. Think of a student practicing a math problem. They solve it, check their answer, and if it's wrong, they try again using what they learned from the mistake.

This process helps AI improve at tasks like writing, coding, or even playing games. It's like a continuous cycle of doing, checking, and adjusting until the AI reaches a good outcome.

The expert version

In AI, 'loops' refer to iterative processes where a system executes a task, evaluates the outcome, and uses that feedback to modify its subsequent actions or parameters. This is fundamental to many learning algorithms and agentic systems.

These loops can range from simple feedback mechanisms within a single model's inference step to complex agentic cycles involving multiple tools, observations, and planning stages. The efficiency and effectiveness of these loops are critical for achieving complex goals and adapting to dynamic environments.

Why it matters now

AI agents are increasingly being designed to perform complex tasks that require iterative refinement. This involves agents repeating cycles of action, evaluation, and adjustment to achieve goals, as seen in coding, design, and scientific problem solving. The term 'loops' captures this essential process of repeated, self-correcting steps in agentic AI.

Questions people ask

How do loops help AI get better?
Loops allow AI to try tasks, see what works and what doesn't, and then adjust its approach for the next try. This continuous improvement cycle leads to better performance over time.
Are loops the same as AI training?
Loops can be part of training, but they also happen when an AI is actively working on a task (inference). Training is about learning from data, while loops during inference are about executing and refining actions.
