AI Agents: What They Are and How They’re Changing Work in 2025

AI Agents: What They Are and How They’re Changing Work in 2025

Artificial intelligence is no longer just about chatbots that follow a script. A new generation of software known as AI agents is taking center stage. You may have heard the term used loosely, so this article explains what AI agents are, how they work, and why they are becoming important for everyday tasks. It also highlights practical frameworks and real-world uses.

What Are AI Agents?

An AI agent is an autonomous program that perceives its environment, reasons about what it senses, and takes actions to achieve specific goals. Unlike a simple chatbot, an AI agent integrates decision-making, learning, memory, and multi-step planning. The MarkTechPost guide notes that agents can manage data, call tools and APIs, and act without constant human intervention.

Researchers in early 2025 agreed that these agents differ from typical AI systems. They emphasized that agents plan, reason, learn, and interact with their environments to accomplish complex objectives. In practical terms, an agent knows your goal, decomposes it into steps, and executes those steps using available tools. This autonomy makes them more adaptable than traditional automation.

Key Traits of AI Agents

AI agents share a set of core abilities that distinguish them from basic automation:

  • Autonomy: Agents operate with minimal supervision. They can initiate tasks and make decisions on your behalf.
  • Learning and adaptation: Agents learn from feedback and improve over time.
  • Reasoning and decision-making: Agents use models (often large language models) to interpret information and plan actions.
  • Memory: Short-term memory helps agents keep context within a session, while long-term memory stores preferences and history.
  • Tool usage: Agents can call external APIs, run code, or interact with other software to perform tasks.
  • Planning: Agents break down goals into sub-tasks and execute a sequence of actions.

These traits allow agents to handle multi-step workflows, from answering questions to booking flights, without you micro-managing every step.

How AI Agents Work

AI agents are built from several interconnected components rather than being a single monolithic program. Here’s how the parts fit together:

Perception and Memory

An agent first perceives inputs—text, voice, images, sensor data or API responses. It processes these inputs into an internal representation, then stores context in short-term memory and longer patterns in long-term memory. Memory lets an agent recall previous interactions, personalize responses, and learn from past outcomes.

Planning and Decision-Making

Agents rely on a processing module—usually a large language model—to analyze information and decide what to do next. They convert high-level goals into smaller tasks, simulate possible actions, and select a sequence that should achieve the goal. Planning algorithms such as Tree-of-Thoughts or reinforcement learning help them choose efficient paths.

Tool Use and Autonomy

Once a plan is in place, the tool use module allows agents to call APIs, execute code, search the web, or interact with software. This step sets them apart from chatbots: they can fetch live data, perform calculations, or control devices. The agent then evaluates the outcome, updates its memory, and decides whether to take another action. This loop continues until the goal is met. The MarkTechPost guide highlights that this integration of perception, memory, planning, and tool use enables agents to function as cognitive layers over data and applications.

Leading AI Agent Frameworks

Several frameworks make it easier for developers to build and deploy AI agents. According to MarkTechPost’s 2025 overview, the most notable include:

  • LangChain: An open-source framework that chains together prompts, tools, and memory. It integrates with services like OpenAI, Anthropic, vector databases, and web scrapers.
  • Microsoft AutoGen: Designed for multi-agent orchestration and code automation. It defines roles such as Planner, Developer, and Reviewer that collaborate via natural language.
  • Semantic Kernel: A toolkit from Microsoft that embeds AI into applications via “skills” and planners. It’s model-agnostic and supports multiple languages.
  • OpenAI Agents SDK: A lightweight SDK optimized for GPT-4. It provides structured workflows with built-in monitoring and guardrails.
  • SuperAGI: An agent operating system offering persistent multi-agent execution, memory management, and a marketplace for components.
  • CrewAI: Focuses on collaborative teams by defining specialized roles (Planner, Coder, Critic) and coordinating them.
  • IBM watsonx Orchestrate: A no-code solution for creating digital workers across enterprise workflows.

These frameworks handle heavy lifting—planning, memory management, and tool integrations—so you can focus on what the agent should accomplish.

Use Cases for AI Agents

AI agents are already being adopted across many domains. MarkTechPost outlines several practical applications:

  1. IT and service desk automation: Agents route help-desk tickets, diagnose issues, and resolve common problems.
  2. Customer support and sales: They handle inquiries, recommend products, and even manage returns.
  3. Contract and document analysis: Agents can extract and summarize data from contracts, reducing time spent by up to 75%.
  4. E-commerce and inventory management: They predict demand, track inventory, and process returns.
  5. Logistics and operations: Agents optimize routes and monitor equipment health; UPS reportedly saves hundreds of millions of dollars through AI-driven route optimization.
  6. HR and finance: Agents process HR queries, automate invoice processing, and perform financial reconciliation.
  7. Research and analytics: They summarize reports, retrieve insights, and generate dashboards.

These examples show how agents are moving from labs into everyday workflows, saving time and improving efficiency.

How AI Agents Differ from Chatbots and LLMs

It’s easy to confuse AI agents with chatbots or large language models. The MarkTechPost article compares the three. Chatbots are reactive—good for answering specific questions but limited to predefined scripts. LLMs like GPT-4 generate text and provide context but lack persistent memory and decision-making. AI agents combine LLMs with memory, planning, tool use, and feedback loops to create autonomous systems. They are proactive, goal-oriented, and adapt as they execute tasks. This integration makes them powerful but also introduces challenges.

Challenges and the Path Ahead

Despite the buzz, AI agents are not a panacea. Early research highlights concerns about safety, ethics, and control. Fully autonomous agents raise issues of alignment with human values, security risks, and potential misuse. Balancing autonomy with oversight is an active area of research. For example, frameworks like CrewAI emphasize roles that allow humans to audit or override decisions.

Another challenge is evaluating agent performance. Benchmarking initiatives such as AARBench, AgentEval, and HELM are emerging to measure task execution and tool use. You should also be aware of data privacy and transparency when deploying agents in sensitive areas.

On the positive side, the field is progressing quickly. Multi-agent systems, modular architectures, improved planning algorithms, and robust safety protocols are advancing. Many frameworks now provide guardrails and monitoring to mitigate risk. As these systems mature, expect agents to become reliable co-workers that extend your capabilities rather than replace you.

Getting Started

If you’re curious to experiment with AI agents, several resources exist. Open-source templates from LangChain, AutoGen, and SuperAgent allow you to build simple agents without deep coding expertise. Start with a focused goal—such as automating email responses or summarizing documents. Pay attention to memory management and define clear boundaries for what the agent can do. Over time, you can add more tools and refine the agent’s behavior.

For a broader perspective, check out the MarkTechPost guide on agent architectures and the ML-Science landscape analysis that explores evolving definitions and capabilities. These articles provide deeper dives into frameworks, research developments, and future directions.

Conclusion

AI agents are shifting the focus of artificial intelligence from passive chatbots to autonomous partners. By combining perception, memory, planning, tool use, and learning, agents can perform complex, multi-step tasks. They are already transforming IT support, customer service, logistics, and more. While challenges remain around safety, evaluation, and ethics, the momentum is clear. As frameworks mature and best practices emerge, AI agents will likely become an integral part of how you work and interact with technology.

How To Set up Philips Hue Without Bridge

How To Set up Philips Hue Without Bridge

Philips Hue is a smart lighting system that uses your existing wireless network. It has WiFi light bulbs, LED lights, and a bridge that connects them to the network. It’s innovative, but the setup can be complicated especially for newbies to the smart home ecosystem.

We wanted to dive a little bit into the process to set up Philips Hue without Bridge; to simplify it because we’ve seen a handful of users complain about the difficulty of using Philips smart bulbs without the bridge. Certain options (if you know what you’re looking for), such as Bluetooth or Dimmer Switch, can help you complete the Philips Hue Smart lighting setup without a bridge.

Philips Hue Bluetooth Bulbs

Philips Hue Bluetooth bulbs are a great addition to any room. With these bulbs, you can forgo the option of not needing to use the Hub at all and just use the Bluetooth connection to sync the bulbs. I’m not the biggest fans of hubs. I’ll use them where I absolutely have to, but leveraging Bluetooth for connectivity is simple and effective. Previously, the Philips BT App used this feature, but now the Bluetooth feature is also included in the Hue app.

Although Philips Bluetooth is a great feature, it has a few limitations. For example, you’re limited to using only 10 bulbs without any provided remote control by the company. Not a deal-breaker, but if you want to go nuts and really light your smart home this might cause some frustration. Third-party app integrations are not supported for integration. Also, the connection is a bit weak for creating large groups of bulbs at the farthest ends of a house. With this option, the grouping wouldn’t be available with these bulbs either. However, technically, one can create groups within a room, so there is a slight workaround in that regard. This can give you free rein over the aesthetics and dynamics of the room. Overall, the Philips Hue bulb is a great addition to any house and the Google Seamless setup can be integrated to make them work without using a Hue bridge.

Using A Hue Dimmer Switch

The Hue Dimmer Switch controls the Hue Bulb when you buy the two together. What’s nice is you don’t have to go through the hustle of connecting the two because they are linked together. The dimmer switch operates via a battery.

You can put the bulb in the socket and turn it on with the dimmer switch. Super easy. The switch allows turning the bulb on or off and controlling the intensity of light. It does not control the change of the light color in the bulb. For that, you’ll have to use the hue bridge. I wish (if you make dimmer switches here’s one of my free tips for innovation) these switches were multi-dimensional, which would give you the option of controlling the intensity of light along with the color (at least warm vs soft light which shouldn’t be that difficult to program).

TRENDING: Setup An Easy and Cheap Smart Home Intercom System

A dimmer switch works like the switch of a light bulb and it supports up to 10 bulbs. It comes with a connected LED light which is synced with the bulb to confirm the establishment of a connection between the two. It is one of the easiest ways to set up Philips hue lights without a bridge. For the extreme novice user of these smart bulbs, it’s the route I’d recommend.

Philip Setup With Amazon Echo Hub

Philips Hue Bulbs are supported by a feature that allows one to use Zigbee smart home hubs supported by Zigbee standards. You can use Hue bulbs after completing the setup of Amazon’s Echo speaker models.

Echo speakers, such as the Amazon Echo Plus, Amazon Echo Show 10 (not first-gen), (4th-gen) Echo, and Echo Studio can be used as Zigbee hubs to support the Philip setup without a bridge. After using Echo speakers, use the Alexa app to search for the hue bulb. Once the device is detected, the next part is adding the hue bulb by using the plus button on the interface of your screen.

Custom scenes cannot be created (as of the date this was published), but you can group smart lights of different brands with the Amazon Echo hub option. For controlling the light, Alexa can be used to control all the features of light by using your voice or entering the instructions on Alexa.

Using An Ikea Trådfri Gateway As A Hub

The Ikea Tradfri gateway plugs directly into an outlet and controls the communication between your phone and the bulbs. The smart bulbs are already installed by you, and you have to connect the Ikea Tradfri gateway directly to the router.

After this, it starts working. The semi-simple process is to hold and press the button for ten seconds within approximately two centimeters of the router. After releasing the button, the light will blink, confirming that the hue light has been added. The Ikea Tradfri system is great because it saves the person from the hustle of plugging two hubs into the router.

However, there are certain limitations, such as you can’t enjoy scheduling, geolocating, and color cycling options that otherwise you could enjoy with a hue bridge. But, the Ikea Tradfri gateway is a great option to be used as an alternative to Philip’s set-up with a hue bridge.

To Bridge Or Not To Bridge

There are a lot of reasons why I like the option to use the bridge and there are some reasons I’d opt out. Chief among them, the Philips Hue bridge makes it easy to control all of your Philips smart bulbs from one central location. Whether that’s your smartphone, tablet, or computer…it doesn’t matter. With the bridge, you can easily turn lights on or off, dim or brighten them, and even change their color. You can also create custom lighting scenes for different occasions, so your home always has the perfect ambiance. You truly unlock the technology’s potential by using it. On the flip side, setting up your Philips smart bulbs with Amazon Alexa is really easy and if you have your smart home ecosystem integrated already with Alexa, it’s a no-brainer.

What I love about the innovation and evolution of technology (smart home technology included) is the improvements being made to fit the end user. Gone are the days when a person would have to stick to one process of setting up a lighting system. Nowadays, there are alternatives and options, which I’m a big fan of.

How to Make Calls on Your Google Smart Speaker

How to Make Calls on Your Google Smart Speaker

Google Home App has introduced a very useful feature that allows users to make calls to all their contacts rather effortlessly. What’s nice is this added feature lets a person set up a Google Home App and then use its modified features to make calls from smart speakers to businesses or personal contacts. If the technology was completely synced with all of your smart devices (smart watch, smartphone, wireless earbuds), I could see how this would be a major component for your smart home. But some of these wishes just aren’t there yet. And to be honest…despite what you might think, the process of setting this up is quite simple. You just have to make sure you have the latest software version and follow the steps to make calls through Google conveniently.

Setting Up Calls On Google Home

  • The first step in making calls to your desired (business or personal) contacts is to configure the prerequisite settings on the device. 
  • To make a call to your Google contacts, you must go to Settings. In the settings, you have to tap on the “more settings” feature. 
  • Locate the tab named Devices 
  • Here, you have to add the desired contact by selecting a speaker of your choice. 
  • While doing so, you must ensure that your personal results toggle is turned on.

Syncing Your Contacts

The process of syncing the contacts on Android or iOS works differently. 

For Android

  1. You have to go to Google Home App. 
  2. In the Google Home app, select manage your Google account
  3. In the Google Account, there is a feature named People and Sharing
  4. In this feature, tap on contact info from your devices, and simply turn on save contacts from your signed-in devices.

For iOS

  1. Go to the Google Home app and tap on settings. 
  2. In settings, hit the more settings tab and select voice and video calls from the services tab. 
  3. Here, select the Mobile Calling tab that appears, and turn on the ‘Contacts uploading’ tab. 
  4. After that, a pop-up will appear asking for permission. If permission is granted, the contacts will successfully be synced.

Add Or Hide Your Number:

In the Google Home app, you can hide your number and appear as a private caller or with your identity. 

  1. Click on the Settings tab, tap more settings, and select Services.
  2. In Services, tap on Voice and Video Calls and Mobile Calling to change your name from Private to your name. 
  3. You will be asked to confirm the action via an SMS. 
  4. Once the technical formalities are done, your number is added to the selected name. 

TRENDING: Digital Assistants: The Uninvited Guest

Making Phone Calls On Google Home:

To make a call to your desired contact, you will have to say, ‘Hey, Google, call (contact)’. From here, there are two possibilities:

  • If you want to call any popular business, you just have to mention the name of that business. Google can automatically take you to the phone line of the business. 
  • If you want to call any personal contact, you have to say the number out loud for Google to connect to the caller. The person you call doesn’t have to go through any prerequisites to receive the call. 

How To End A Call?

Voice commands such as, “Hey Google, stop/disconnect/hang up/end the call” can be used to end the call. But Google provides users with other options as well. 

The other options include Google Nest Hub, Hub Max, and Google Nest Mini. 

  • In Google Nest Hub, a button on the screen allows you to decide on your calls (answer/decline/hang). 
  • In Google Nest Mini, one can tap the speaker’s top to answer or hold a finger down to decline the call. 
  • Additionally, if you have a Google Home Max, you may answer calls by tapping the line on the top or side of the speaker, depending on how it’s oriented, or by pressing and holding the line.

RELATED: Google Family Link: My Go-To App

Setting Up Voice Match For Google Home Calls:

If you have a Google Home App running on your phone, the next step is to train your Google assistant. After that, the assistant will work by recognizing your voice. The only real necessity of this is that your personal accounts must be synced so that it picks the calls and access your contacts based on the settings you have selected. 

Bottom Line 

Making calls from Google Smart Speaker has enabled people to shift from obsolete ways of calling and bring communication into the future. Previously, Google Assistant helped people in making calls. Now, the Google Home App has made it possible to contact anyone essentially from any part of the world with just an app. 

There are a lot of nice things about making phone calls using your smart speaker. In a lot of regards, it is convenient. For example, the Google Home App detects the speaker’s voice once the setup is completed. You have to personalize all the settings to make use of the feature to the fullest. Once everything is set, you just have to say the command, and Google will dial up that call for you.

Now…this isn’t something I use often. Most of the time when I make calls through a smart speaker, it’s when I don’t have my phone or wireless headphones near me. In this regard, this feature is awesome. But having the ability to make a phone call through my wireless buds (connected to my phone) or even through my smartwatch is much more convenient than doing it through one of these smart speakers. Nonetheless, for those that don’t have these smart accessories that pair with their smartphones, making a call through your Google smart speaker definitely has it’s purpose.

Social Media Layoffs: The Impact It Will Have On You And Your Digital Citizenship

Social Media Layoffs: The Impact It Will Have On You And Your Digital Citizenship

In recent weeks, both Twitter and Facebook have made headlines for laying off a significant number of employees. An estimated 7500 employees were laid off at Twitter and it’s been reported that Meta (Facebook’s parent company) laid off more than 11,000. While these layoffs are undoubtedly having an impact on the companies themselves, they also raise important questions about what they could mean for the users of these social media platforms. Quite frankly, I’m shocked this isn’t one of the main takeaways from all of this. Let’s take a closer look at the potential implications of these layoffs.

Less Money for Innovation And Expansion

One of the most immediate impacts of these layoffs is that there will be less money available for innovation on Twitter and Facebook. This is because, when a company lays off employees, it is also losing its collective knowledge and expertise. In a lot of cases, these budgets get cut along with the workforce. For example, when Facebook laid off its team of Trending Topics curators, it lost a wealth of experience and knowledge about what topics are being talked about online. As a result, the company has been forced to rely more heavily on algorithms to surface Trending Topics, with mixed results.

In addition, with fewer employees working on a given project, there is less capacity for trial and error. This means that we can expect to see fewer new features being rolled out across all social media platforms in the coming months. So if you’re waiting for that new Facebook update or that new Twitter tool, you may have to wait a little longer than usual.

Fewer Customer Service Resources

Another potential impact of the social media layoffs is that there may be fewer customer service resources available to users. This is because, when companies lay off employees, they often do so in areas where they feel they can save the most money. And customer service is typically one of those areas. If you’ve noticed that it’s taking a bit longer to get a response from Twitter or Facebook when you report a problem, this is likely why.

An Increase In Social Media Scams

Hackers are opportunists (the good kind and bad). There are already numerous social media scams hitting every social media platform out there. I highly suspect that social media scams attacking Facebook and Twitter users will ramp up in the coming weeks.

DISCOVER: The Most Popular Social Media Scams

Lack Of Resources For Security

Yes, many of these layoffs have been those in roles of management (at least with Twitter). But we don’t know the entire scope of which departments and job titles were impacted. These companies are going to hesitate to release a detailed itemized sheet of what people and departments were affected the most. Regardless, your personal data being stored on any of these social media companies’ servers could be at risk. Heck…they’re always at risk when budgets are endless and companies do have all the resources. So what should you do?

Quick + Effective Ways To Protect Your Social Media Accounts

Enable 2FA Where Possible

Two-factor authentication (2FA), a sort of multi-factor authentication (MFA), is a security procedure that cross-verifies people using two separate types of identity. This type of added security feature will help you get that extra layer of protection in addition to putting in your password. In my opinion, if ANY platform, app, website, etc. will allow you to enable 2FA…YOU DO IT. The good news is both Facebook and Twitter have the option to enable two-factor authentication. Is it annoying to use at times? I’d be lying if I said “No.” But considering how much personal information and data these social media servers have on you…it would be very wise to enable 2FA.

RELATED: What Is Two-Factor Authentication?

Change Your Passwords

You’d be surprised how some people never change their passwords. You’d be even more surprised by the number of people that have dumb passwords that can easily be hacked. I’ve detailed exactly how you can make your passwords strong and more secure.

Social Media Layoffs Will Impact You

The layoffs at Twitter and Facebook are undoubtedly having an impact on the companies and their users. With fewer resources available for innovation and customer service, users can expect to see fewer new features and may have difficulty getting help when they need it. However, it’s important to remember that social media platforms are still incredibly popular and widely used despite these challenges. While the layoffs may be having an impact in the short term, it’s unlikely that they will have a significant long-term effect on either company’s bottom line.
