The paradigm worked well for FAQs, simple ticket routing, or basic conversational marketing. Yet the expectations of users—and the capabilities of modern large language models (LLMs)—have outgrown that narrow definition. ...

Early rule‑based chatbots gave way to large language models (LLMs) that can generate human‑like text, and today we stand on the cusp of the next evolution: agentic workflows—systems that not only converse but act autonomously in dynamic environments. ...

The era of the “chatbot” is rapidly evolving into the era of the “agent.” For the past two years, the world has been captivated by Large Language Models (LLMs) that can write essays, debug code, and hold witty conversations. However, the limitation of these models has always been their isolation; they could talk about the world, but they couldn’t do anything in it. Enter Large Action Models (LAMs) and Agentic Workflows. We are currently witnessing a seismic shift from passive text generation to active task execution. With the recent explosion of high-quality, open-source LAMs and agent frameworks, the power to build autonomous systems that navigate the web, manage software, and orchestrate complex business processes is no longer restricted to Big Tech labs. ...

Unlike traditional request-response systems, agents autonomously plan, execute, and adapt their actions to achieve complex goals. In 2026, the landscape has matured significantly—LLM providers offer robust function calling, frameworks have standardized on proven patterns, and production deployments are increasingly common. ...

This tutorial explains how modern AI agents (like those in Cursor, IDE copilots, and autonomous coding tools) create, maintain, and execute to-do lists — and how you can build the same capability from scratch to production. This is not a UX trick. A to-do list is the core cognitive control structure that turns a language model from a chatty assistant into an agent that finishes work. 1. Why To-Do Lists Matter for Agents Large Language Models (LLMs) do not naturally: ...
