AI and LLM fundamentals

An agent loop alternates decision, action, and observation. ReAct is a pattern that combines deciding what information/action is needed with executing tools and observing results. “Reasoning” here means useful task planning and decision-making, not a…

Multi-agent systems involve several model-driven roles cooperating. Hierarchical systems organize those roles into levels of coordinators and workers. Multiple ordinary functions in a workflow are not automatically multiple agents.

A router chooses a specialized path based on the request. It can use deterministic rules, a classifier, or an LLM with a bounded enum output. Routing does not automatically require a full agent loop.

An AI agent is software that uses a model to choose actions toward a goal, observes results, and decides what to do next within application limits. A chatbot describes a conversational interface; it may or may not contain an agent. A workflow defines the…

A planner proposes steps; an executor performs permitted steps and reports results. Splitting the roles separates deciding from acting. The executor still enforces constraints rather than blindly following the plan.

Reflection revises an output after examining it. A critic is a separate checking role that evaluates an output against criteria. Either can be model-based, rule-based, or a combination.

A supervisor coordinates specialized workers and often combines their outputs. A handoff transfers responsibility for a conversation or task to another specialist. Coordination and transfer are different: the supervisor may retain ownership, while a handoff…

Tools are approved external capabilities. Planning breaks a goal into steps; state records current execution facts; memory carries selected information across turns or tasks. Autonomous action means the system can perform some actions without a new user…

Human-in-the-loop means a workflow includes a person who supplies information, reviews a result, or authorizes an action. The system can pause durably while waiting. Human approval is a business event with identity and scope, not a sentence in the prompt.

The OpenAI Agents SDK provides agent-oriented building blocks for model calls, tools, handoffs, and run management. It offers a higher-level agent interface than manually processing each API response. SDK features and provider integration details depend on…

I identify its intended version, consult the current official docs, and separate the concept from the old API. I pin compatible dependencies and avoid mixing legacy chain APIs with newer agent construction patterns.
