This week brought big news about AI agents - smart computer helpers that can work on their own to solve problems. The week showed that AI agents are becoming more real and practical in the business world.

One major update came from Google Cloud, which released a detailed guide for building AI agents. This guide helps companies create these smart helpers correctly. Google thinks the AI agent market could grow to about $1 trillion by 2035-2040.

Another important announcement came from Kyndryl, a technology company based in New York, USA. They created new services to help companies prepare their workers for AI agents. This is important because AI agents will change how people work and do their jobs.

Companies also announced new types of AI agents that work in different ways. Some AI agents work like a team where one leader gives tasks to other agents - called Hierarchical Cognitive Agents. Others work like a group where all agents help each other equally - called Swarm Intelligence Agents. Each type works better for different kinds of problems.

Microsoft and Google also released their own AI models to power agents. Microsoft created MAI-Voice-1, a model that can understand and create speech very quickly. Google started letting all companies use their Ads Advisor and Analytics Advisor tools, which use AI to suggest better ways to run advertisements.

The search results also showed that real companies are already using AI agents to do important work. Banks use AI agents to trade stocks, hospitals use them to help doctors find better treatments, and stores use them to help manage operations better. By 2026, Gartner predicts that 40% of business software will include AI agents, up from less than 5% in 2025.

However, there was also scary news this week about a demonstration of AI agents being used to attack computer systems. Security experts showed how AI agents could work together to find and exploit weaknesses in computer systems without human help. This means companies need to get ready now to protect themselves.

Overall, this week showed that 2025 is truly the year of AI agents. These smart helpers are moving from test projects to real-world use in companies around the world. The week's announcements proved that AI agents are not just ideas - they are tools that companies are building and using right now.
