Agent
An autonomous AI system equipped with diverse tools and reasoning capabilities that continuously perceives its environment and takes actions to achieve a goal.
Think of It Like This
Like a digital employee who doesn't just answer questions, but actively opens spreadsheets and browses the web to finish the job you gave them.
Unlike static language models that merely output text, agents execute a continuous loop of planning, acting, and observing. They can browse the web, write code, or query databases to solve complex, multi-step problems without human intervention. The reliability of an agent largely depends on its ability to recover gracefully from tool failures and unexpected environment changes.
