What is an AI Agent?

AI agents are software systems, those use AI to complete goals and tasks on the place of users. They work with reasoning, planning, and memory and have a level of autonomy to make decisions, learn, and adapt.

Key Features of AI Agents

1. Autonomy: The best feature AI Agents has it that they can operate independently once you give them a goal. They don't need step-by-step instructions; they figure out the path themselves. And they found the best path.

2. Goal-Directed Behaviour: Everything an agent does is oriented toward completing an objective and goal. It plans, prioritises, and executes with that end state in mind by itself. 

3. Tools: AI Agents use external tools, web search, code runners, APIs, databases, file systems, email, and calendars. With the help of these tools, AI Agents achieve all the goals accurately. 

4. Memory

• Short-term: context within the current task (what's been done, what's pending)

• Long-term: retain knowledge across sessions (user preferences, past outputs, learned patterns) 

5. Reasoning: AI Agents break complex goals into sub-tasks, sequence them logically, and adapt the plan when something doesn't work.

6. Self-Correction: AI Agents don’t work cluelessly; they do observe the result of each action and adjust. If the code fails, they debug it by themselves. That’s why they don’t need human interference, they build and improve by themself.
