The best free AI courses and certificates in 2025 - and I've tried many

1 week ago 19

Generative AI is an astonishing technology that's not only here to stay but promises to impact all sectors of work and business. It's already made unprecedented inroads into our daily lives.

We all have a lot to learn about it. Spewing out a few prompts to ChatGPT may be easy, but before you can turn all these new capabilities into productive tools, you need to grow your skills. Fortunately, there is a wide range of classes that can help.

Many companies and schools will try to sell you on their AI education programs. But as I'll show in the following compendium of great resources, you can learn a ton about AI and even get some certifications -- all for free.

I have taken at least one class from each of the providers below, and they've all been pretty good. Obviously, some teachers are more compelling than others, but it's been a very helpful process. When working on AI projects for ZDNET, I've also sometimes gone back and taken other classes to shore up my knowledge and understanding.

So, I recommend you take a quick spin through my short reviews, possibly dig deeper into the linked articles, and bookmark all of these, because they're valuable resources. Let's get started.

Course selection: Huge, more than 1,500(!) AI courses
Program pricing: Free trial, then $39.99/mo

LinkedIn Learning is one of the oldest online learning platforms, established in 1995 as Lynda.com. The company offers an enormous library of courses on a broad range of topics. There is a monthly fee, but many companies and schools have accounts for all their employees and students.

LinkedIn Learning is probably the one online education site I've used more than any other -- starting back in the late 1990s. For years, I paid for a membership. Then, I got a membership as an alum of my grad school, which is how I use it now. With so many courses on so many topics, it's a great go-to learning resource.

I took two classes on LinkedIn Learning. Here's my testimonial on one of them.

I also took the two-hour Machine Learning with Python: Foundations course, which had a great instructor -- Prof. Frederick Nwanganga -- who was previously unknown to me. I have to hand it to LinkedIn. They choose people who know how to teach.

I learned a lot in this course, especially about how to collect and prepare data for machine learning. I also was able to stretch my Python programming knowledge, specifically about how a machine learning model can be built in Python. In just two hours, I felt like I got a friendly and comprehensive brain dump.

Since there are so many AI courses, you're bound to find a helpful series. To get you started, I've picked three that might open some doors:

ChatGPT Tips for the Help Desk: Learn to apply strategic planning, prompt engineering, and agent scripting, as well as other AI techniques, to AI operations.
Machine Learning with Python: Foundations: Get step-by-step guidance on how to get started with machine learning via Python.
Building Career Agility and Resilience in the Age of AI: Learn how to reimagine your career to adapt and find success in the age of AI.

It's worth checking with your employer, agency, or school to see if you qualify for a free membership. Otherwise, you can pay by month or year (the by-year option is about half price).

A company representative told ZDNET, "LinkedIn Learning has awarded nearly 500K professional certificates over the past 2.5 years. And, generative AI is one of the top topics represented."

Course selection: 93
Program pricing: Free during the Skills Fest, mostly free after

Microsoft earned itself a Guinness World Record for its online training session called Skills Fest, which ran in April and May of 2025. This was a mixed combination of live and on-demand courses that anyone could take for free. The only cost was giving up your email account and registering with Microsoft.

Also: You can get free AI skills training from Microsoft for a few more days, and I recommend you do

Here are three courses I took. The Minecraft one was adorable, and I recommend it for a kids' intro to generative AI.

AI Adventurers: A Minecraft Education presentation about the basics of generative AI
Building applications with GitHub Copilot agent mode: YouTube video that teaches how to use the new agent mode in GitHub
AI for Organizational Leaders: A LinkedIn Learning course with a certificate

Not all the courses are available on demand. After Skills Fest ends, you should be able to get to the course catalog by visiting this link. There's a Filters block on the left. Click On-Demand and then Apply Filters. You should see a bunch of courses still available for you to enjoy.

Course selection: Quite a lot
Program pricing: Many free, some on a paid subscription

Amazon puts the demand in infrastructure on demand. Rather than building out their own infrastructure, many companies now rely on Amazon to provide scalable cloud infrastructure on demand. Nearly every aspect of IT technology is available for rent from Amazon's wide range of web services. This also includes a fairly large spectrum of individual AI services from computer vision to human-sounding speech to Bedrock, which "makes LLMs from Amazon and leading AI startups available through an API."

Also: I spent a weekend with Amazon's free AI courses, and highly recommend you do too

Amazon also offers a wide range of training courses for all these services. Some of them are available for free, while others are available via a paid subscription. Here are three of the free courses you can try out:

Foundations of Prompt Engineering: Learn about the principles, techniques, and best practices for designing effective prompts.
Amazon Bedrock -- Getting Started: Learn about Amazon's service for building generative AI applications.
Twitch Series: AWS Power Hour Introduction to Machine Learning for Developers: This is a recording of a Twitch-based learning chat series. It helps you learn the foundations of machine learning and get a practical perspective on what developers really need to know to get started with machine learning.

In addition to classes located on Amazon's sites, the company also has quite a few classes on YouTube. I spent a fun and interesting weekend gobbling up the Generative AI Foundations series, which is an entire playlist of cool stuff to learn about AI.

If you're using or even just considering AWS-based services, these courses are well worth your time.

Course selection: Fairly broad IT and career building
Program pricing: Free

IBM, of course, is IBM. It led the AI pack for years with its Watson offerings. Its generative AI solution is called Watsonx. It focuses on enabling businesses to deploy and manage both traditional machine learning and generative AI, tailored to their unique needs.

The company's SkillsBuild Learning classes offer a lot, providing basic training for a few key IT job descriptions -- including cybersecurity specialist, data analyst, user experience designer, and more.

Right now, there's only one free AI credential, but it's one that excited a lot of our readers. That's the AI Fundamentals learning credential, which offers six courses. You need to be logged in to follow the link. But registration is easy and free. When you're done, you get an official credential, which you can list on LinkedIn. After I took the course, I did just that -- and, of course, I documented it for you.

My favorite was the AI Ethics class, which is an hour and 45 minutes. Through real-world examples you'll learn about AI ethics, how they are implemented, and why AI ethics are so important in building trustworthy AI systems.

Course selection: Nearly 90 AI-focused courses
Program pricing: Free

DeepLearning is an education-focused company specializing in AI training. The company is constantly adding new courses that provide training, mostly for developers, in many different facets of AI technology. It partnered with OpenAI (the makers of ChatGPT) to create a number of pretty great courses.

I took the ChatGPT Prompt Engineering for Developers course below, which was my first detailed introduction to the ChatGPT API. If you're interested in how coders can use LLMs like ChatGPT, this course is worth your time. Interspersing traditional code with detailed prompts that look more like comments than commands can help you understand these two very different styles of coding.

Three courses I recommend you check out are:

ChatGPT Prompt Engineering for Developers: Go beyond the chat box. Use API access to leverage LLMs into your own applications, and learn to build a custom chatbot.
Evaluating and Debugging Generative AI Models Using Weights and Biases: Learn MLOps tools for managing, versioning, debugging, and experimenting in your ML workflow.
Large Language Models with Semantic Search: Learn to use LLMs to enhance search and summarize results.

With AI such a hot growth area, I am always amazed at the vast quantity of high-value courseware available for free. Definitely bookmark DeepLearning and keep checking back as it adds more courses.

Course selection: Thousands of courses on AI alone
Program pricing: Free trial, then $20/mo. Courses are also sold individually.

Udemy is a courseware aggregator that publishes courses produced by individual trainers. That makes course style and quality a little inconsistent, but the rating system does help the more outstanding trainers rise to the top. Udemy has a free trial, which is why it's on this list.

I spent some time in Steve Ballinger's Complete ChatGPT Course For Work 2023 (Ethically)! and found it quite helpful. Clocking in at a little over two hours, it helps you understand how to balance ChatGPT with your work processes, while keeping in mind the ethics and issues that arise from using AI at work.

Udemy offers a $20/month all-you-can-eat plan, and also sells individual courses. I honestly can't see why anyone would buy the courses individually, since most of them cost more for one course than the entire library does on a subscription.

Here are three courses you might want to check out:

ChatGPT Masterclass: ChatGPT Guide for Beginners to Experts!: Gain a professional understanding of ChatGPT, and learn to produce high-quality content seamlessly and grow your earning potential.
Discover, Validate & Launch New Business Ideas with ChatGPT: Learn how to generate startup ideas, evaluate their potential, and test them with customers in real life.
Midjourney Mastery: Create Visually Stunning AI Art: Learn how to use Midjourney to create art.

One of the more interesting aspects of Udemy is that you may find courses on very niche applications of AI, which might not suit vendors offering a more limited selection of mainstream courses. If you have a unique application need, don't hesitate to spend some extra time searching for just the right course.

Course selection: One AI course
Program pricing: Free

Google's Grow With Google program offers a fairly wide range of certificate programs, which are normally run through Coursera. Earning one of those certificates often requires paying a subscription fee. But we're specifically interested in one Grow With Google program, which is aimed at teachers, and does not involve any fees.

The Generative AI for Educators class, developed in concert with MIT's Responsible AI for Social Empowerment and Education, is a 2-hour program designed to help teachers learn about generative AI, and how to use it in the classroom.

Also: Google and MIT launch a free generative AI course for teachers

Generative AI is a big challenge in education because it can provide amazing support for students and teachers and, unfortunately, provide an easy way out for students to cheat on their assignments. So a course that can help teachers come up to speed on all the issues can be very powerful.

The course provides a professional development certificate on completion, and this one is free.

I've been working with AI for a very long time. I conducted one of the first-ever academic studies of AI ethics as a thesis project way back in the day. I created and launched an expert system development environment before the first link was connected on the World Wide Web.

I did some of the first research of AI on RISC-based computing architectures (the chips in your phone) when RISC processors were the size of refrigerators.

I also wrote and deployed the AI Editor, a generative AI tool that built news and content dynamically. That may not seem like much today, but I did it way back in 2010, when I had to create a generative AI engine from scratch. At that point, to work, it had to be distributed across five individual servers, each running one agent of a team of clustered AI agents.

I also have a master's degree in education, focusing on learning and technology. My specialty is adult online learning, so this kind of stuff is right up my alley.

When it comes to the courses and programs I'm spotlighting here, there's no way I could take all of them. But I have taken at least one course from each vendor, in order to test them out and report back to you. And, given my long background in the world of AI, this is a topic that has fascinated and enthralled me for most of my academic and professional career.

With all that, I will say that the absolute high point was when I could get an AI to talk like a pirate.

Let's be clear: A micro-degree is not a degree. It's a set of courses with a marketing name attached. Degrees are granted by accredited academic institutions, accredited by regional accrediting bodies. I'm not saying you won't learn anything in those programs. But they're not degrees and they may cost more than just-as-good courses that don't have a fancy marketing name attached.

Yes, but how much value they have depends on your prospective employer's perspective. A certificate says you completed a course of study successfully. That might be something of value to you, as well.

You can set a goal to learn a topic, and if you get a credential, you can be fairly confident you have achieved some learning. Accredited degrees, by contrast, are an assurance that you not only learned the material but did so according to some level of standard and rigor common to other accredited institutions.

My advice: If you can get a certificate, and the price for getting it doesn't overly stretch your budget, go ahead and get it. It still is a resume point. But don't fork over bucks on the scale of a college tuition for some promise that you'll get qualified for a job faster and easier than, you know, going to college.
