They treat the technology as a tool when they should treat it as an operating system. - Author: Rafael Cordeiro - Tags: Rafael Cordeiro, colunista, #historico-linkedin Most companies are using AI the wrong way. And it is not a technology problem. It is a mindset problem. They treat AI as a tool, when they should treat it as an operating system. One honest question helps tell the two apart. Does your AI make decisions, or does it only answer questions? There is a huge difference between the two. For decades, software did one thing very well. It executed rules defined by humans. AI agents change that. They observe, decide and act. But not all of them do it at the same level. *Editor's context.* The classification broadly matches chapter 2 of the textbook [Artificial Intelligence, A Modern Approach](https://aima.cs.berkeley.edu/contents.html?ref=futureinuse.ai), by Stuart Russell and Peter Norvig, 4th edition. The book divides agents into simple reflex, model-based reflex, goal-based, utility-based and learning agents. ## 1\. Reactive agents They execute simple rules. They do not learn. They do not plan. They are automation, not intelligence. Useful, but limited. ## 2\. Agents with a model of context They already understand their environment. They can operate with incomplete information. They stop reacting blindly. This is where real value begins. ## 3\. Goal-based agents Now the how no longer matters, the why does. They weigh different paths to reach a goal. This is no longer traditional software. It is decision-making. ## 4\. Utility-based agents The real world has trade-offs. Cost, time, risk, quality. These agents choose the best possible compromise, exactly as an experienced manager would. ## 5\. Learning agents This is the watershed. They get better with use, learn from mistakes and adjust their behavior. Now we are talking about systems that evolve. Not features. ## The step almost everyone ignores Multi-agent systems. Not one agent that does everything, but several specialized agents, coordinated, with clear roles. That is how companies scale. That is how complex operations work. It always has been. ### In short - Traditional software executes rules defined by humans. - Agents observe, decide and act, at five different levels. - Companies scale with several specialized, coordinated agents with clear roles. ## The question that matters The question that matters is not which AI tool to use. It is which human decision you are trying to automate, and which one you should not. Companies that understand this early will operate with smaller, faster and smarter teams. The rest will keep asking for answers when they should already be delegating decisions. > **What has changed since January 12, 2026 ยท Editor's note** > Vendors began offering the infrastructure to coordinate multiple agents as a product. On September 10, OpenAI opened the [Agents API](https://futureinuse.ai/openai-agents-api/) in beta, which hosts the layer that coordinates context, tools and subagents. **Further reading** - [The enterprise knowledge layer, the context AI agents need to operate](https://futureinuse.ai/camada-de-conhecimento-ia-empresarial/) - [OpenAI opens up the Agents API](https://futureinuse.ai/openai-agents-api/) - Agentic AI and more autonomous organizations --- *Originally published on LinkedIn on January 12, 2026\.* [*See the original post*](https://www.linkedin.com/feed/update/urn:li:activity:7416603142223564801/?ref=futureinuse.ai)*.
