AI Is Already Part of Everyday Life – but the Next Wave Raises the Stakes
Artificial intelligence has already become commonplace: generative tools are used to create content, search for information, and support customer service just like email or spreadsheets. It’s no longer a question of whether to try AI – but rather, how broadly to apply it.
Now, AI agents have risen to the forefront of the discussion. They don’t just answer questions, but operate independently: planning, making decisions, and using other services to achieve goals – often faster and more efficiently than humans.
At the same time, a familiar phenomenon has emerged around AI agents: FOMO (fear of missing out). Social media and news are filled with stories of companies adopting revolutionary new AI solutions. This can make decision-makers wonder whether their own operations are keeping up – or falling behind on a side track.
We wanted to write this blog precisely to help curb that FOMO. It’s not worth investing in AI agents just because of hype or pressure. The best decisions are always based on knowledge and real need.
To truly understand AI agents, it’s important to first look at what they are not. The rapid pace of AI development can easily blur the meanings of different terms, so a quick recap helps.
Machine Learning
Machine learning means training a model to make decisions based on data.
Practical examples:
An online store recommends products based on past purchases.
A bank detects an unusual card transaction and blocks potential fraud.
Machine learning doesn’t create something new, but instead recognizes patterns and makes predictions or conclusions from existing data.
Generative AI
Generative AI creates new content rather than just analyzing data. It can generate text, images, code, or even music.
Practical examples:
ChatGPT drafts articles, outlines, and responses.
MidJourney or DALL·E create images from text prompts.
Generative AI speeds up work and enriches ideation by producing fresh content and perspectives quickly.
AI Agents – Independent Actors That Learn and Adapt
AI agents differ fundamentally from machine learning and generative AI. They are not just tools for analyzing data or generating content, but systems with the ability to achieve set goals autonomously.
At their core, agents still rely on large language models (LLMs), such as ChatGPT or similar. These serve as the “brains” that understand and generate language. But a language model alone isn’t enough, since its knowledge is limited and tied to its training data.
The distinctiveness of agents comes from their ability to use surrounding tools and services: retrieving real-time data, calling APIs, performing web searches, or even collaborating with other agents. This makes them far more versatile than traditional LLM-based conversational applications.
How Do AI Agents Work? Three Key Steps
1. Goal Definition and Planning
Although an agent is autonomous, it always begins with a goal given by a user or organization. Developers build the rules and constraints, while the user provides tools and sets a concrete objective.
The agent can then break the goal down into smaller parts (“task decomposition”). While not always necessary for simple tasks, it greatly improves results in complex ones.
Example: A tourist – or a travel agency – asks the agent to plan a ski holiday in Lapland. The goal: “Create a one-week itinerary including skiing, a reindeer safari, and northern lights viewing.” The agent breaks this into parts: choosing dates, booking a hotel, scheduling activities, and arranging transportation.
2. Decision-Making and Tool Use
When the agent encounters a challenge it can’t solve on its own, it leverages external tools or services – for example, web search, weather services, flight or hotel booking systems, or even other agents with specialized knowledge.
Continuing the example: the agent needs up-to-date weather forecasts to plan the best nights for northern lights viewing. It fetches data from the Finnish Meteorological Institute’s API and learns that mid-week has the clearest skies. It may also consult another agent specialized in Lapland tourism to identify the best locations for aurora sightings. The plan is then continuously adjusted, like an experienced guide fine-tuning the route.
3. Learning and Reflection
Once the agent has delivered its plan, it saves its experiences to memory. Feedback such as “the hotel was good, but the schedule was too packed” is remembered for future tasks. This allows the agent to better align with user preferences over time.
Agents can also incorporate feedback from other agents or human supervisors (“human-in-the-loop”) to avoid repeating mistakes. Over time, they learn to make fewer errors and better meet expectations.
Why Does This Matter?
“Traditional” generative AI is like a sage answering questions based on what it was trained to know. An agent, by contrast, is like a digital employee: it can ask follow-up questions, use tools, create plans, and adapt to changing conditions.
For organizations, adopting agents is not just about using another tool – it’s about embracing a new way of working. Agents can handle complex processes that once consumed many employees’ time – and improve continuously as they work.
When Should Agents Be Used?
Machine learning excels at analyzing data and making predictions.
Generative AI is best for creating content and ideas.
AI agents step in when independent actors are needed – ones that can use tools and adapt their behavior to circumstances.
Agents add value especially in complex processes, and when simple content or analysis is no longer enough. If the goal is to automate entire workflows and enable continuous learning, agents are the right solution.
