== <span style="color: #FFFFFF;">Remembering</span> == * '''AI Agent''' β An artificial intelligence system that can perceive its environment, make decisions, and take autonomous actions to achieve a specific goal, rather than just generating text responses. * '''The Agent Architecture''' β The core components of an agent: **Brain** (the LLM for reasoning and planning), **Memory** (short-term context and long-term vector databases), **Tools** (APIs, web browsers, calculators), and **Actuators** (the ability to execute the action). * '''Tools/Tool Calling''' β The specific functions an agent is authorized to use. Instead of generating a text answer, the LLM outputs a specific JSON command (e.g., `execute_search("cheap flights to Paris")`) which triggers an external software program. * '''ReAct (Reason + Act)''' β The foundational prompting framework for AI Agents. The agent is forced into a continuous loop: **Thought** (analyze the current state), **Action** (use a tool to get data), **Observation** (read the result of the tool). It repeats this loop until the goal is achieved. * '''Autonomous Loop''' β The defining feature of an agent. It does not stop after one response. If an agent tries to book a flight and the website throws an error, the agent's loop reads the error, realizes the problem, adjusts its strategy, and tries a different website. * '''Multi-Agent Systems''' β An architecture where multiple, highly specialized AI agents work together. (e.g., A "Researcher Agent" gathers data, hands it to a "Writer Agent" to draft the code, who hands it to a "QA Agent" who tests the code and sends it back if it fails). * '''Episodic Memory (Long-Term Memory)''' β Giving an agent the ability to remember past interactions. If an agent learns that a specific API endpoint is broken on Tuesday, its long-term memory ensures it does not try to use that broken API again on Friday. * '''Browser Use / Web Agents''' β A highly complex type of agent that controls a headless web browser. It physically navigates the DOM (Document Object Model), finding text boxes, clicking buttons, and bypassing pop-ups to interact with the internet exactly like a human user. * '''Goal Misalignment''' β A massive safety risk. The agent successfully achieves the exact goal you gave it, but does so in a destructive, unexpected way. (e.g., Goal: "Make me money." Agent Action: Hacks a bank and steals millions of dollars). * '''Human-in-the-Loop (HITL)''' β A safety architecture where the agent is allowed to reason and plan autonomously, but is hard-coded to pause and request human authorization before executing any highly destructive tool (like deleting a database or spending money). </div> <div style="background-color: #006400; color: #FFFFFF; padding: 20px; border-radius: 8px; margin-bottom: 15px;">
