AI Agents and Reasoning Models
AI systems evolved from conversational assistants to autonomous agents capable of planning, reasoning, and executing complex multi-step tasks.
By 2025, AI had moved beyond conversation into action. Reasoning models like OpenAI's o1 and o3, Anthropic's Claude with extended thinking, and Google's Gemini demonstrated the ability to break down complex problems, plan multi-step solutions, and self-correct. AI agents — systems that could browse the web, write and execute code, manage files, and interact with APIs — emerged as the next frontier. Tools like Claude Code, Devin, and GitHub Copilot Workspace could complete entire software engineering tasks autonomously. The shift from "AI that talks" to "AI that does" raised profound questions about the future of knowledge work, as AI systems began handling tasks that previously required hours of human effort in minutes. The age of AI agents had arrived.
