Best ChatGPT Courses in 2026: A Full Guide

ChatGPT is easy to open and hard to use well. With ChatGPT, people type a question, get a passable answer, and never find out what the tool does when you give it context, examples and a clear format to work to.

A good ChatGPT course closes that gap in an hour or two. This list covers the best options for complete beginners, for prompt engineering, for custom GPTs, for specific jobs, and for developers who want to build on the OpenAI API.

Most picks are our own courses, because we can show you verified ratings and learner numbers for them. Where someone else does a job better, we say so.

Best ChatGPT Courses Compared

Best ChatGPT Courses For Beginners

The best ChatGPT course for beginners teaches you to write a clear prompt, check the answer, and know what not to paste into the chat box. All 3 picks below do that in 2 hours or less.

1. Introduction to ChatGPT

Our newest ChatGPT course, and the one we point beginners to first.

• Level: Beginner
• Time: 1 hour
• Cost: Included in a DataCamp subscription. The first chapter is free.
• Best for: Complete beginners who want to be useful with ChatGPT by the end of the day

The course covers how to phrase a request, how to get more accurate responses, and how to use AI safely at work. It runs in 2 chapters and takes about 1 hour.

It was last refreshed in Jul 2026, so the screenshots and features match the ChatGPT you will actually open. It holds a 4.8/5 rating from 5,784 reviews.

2. Understanding ChatGPT

Our most-taken ChatGPT course, and the first course in the ChatGPT Fundamentals track.

• Level: Beginner
• Time: 1 hour
• Cost: Included in a DataCamp subscription. The first chapter is free.
• Best for: Learners who want the business use cases alongside the basics

With 437K learners, this is the course most people start with. It covers prompt best practices and common business uses such as drafting, summarising and brainstorming.

Its last content refresh was Sep 2025, which is older than our Introduction to ChatGPT. Take this one if you plan to finish the full track, since it is the first step.

3. Introduction to AI for Work

A wider course that puts ChatGPT next to the other AI tools you will meet at work.

• Level: Beginner
• Time: 2 hours
• Cost: Included in a DataCamp subscription. The first chapter is free.
• Best for: People whose employer has just rolled out AI tools and asked everyone to use them

This course spends less time on ChatGPT specifically and more on what AI is and how to use it responsibly. It is the most-taken course in our AI Fundamentals track with 126K learners.

Its rating of 4.7/5 is a little lower than the ChatGPT-specific courses above. Choose it if you need the bigger picture rather than one tool.

Our pick: Start with our Introduction to ChatGPT. It is the most current of the three and takes 1 hour. Add Introduction to AI for Work if your workplace uses more than one AI tool.

Best Free ChatGPT Course

The best free ChatGPT course comes from OpenAI itself. Our courses let you take the first chapter free, but a full free course with a certificate is a different offer, and OpenAI's is a good one.

1. AI Foundations (OpenAI Academy)

OpenAI's own beginner course, hosted on OpenAI Academy and open to anyone with a ChatGPT account.

• Level: Beginner
• Time: Self-paced
• Cost: Free. Needs a ChatGPT account, which is also free.
• Best for: Learners who want an official certificate without paying

AI Foundations covers the core habits: prompting, giving context, and evaluating what comes back. It ends with an assessment and a certificate of completion.

That certificate is a course-completion record, not OpenAI's separate paid certification program. Describe it accurately on a CV or LinkedIn profile.

Our pick: Take OpenAI Academy's AI Foundations if cost is the deciding factor. If you already have a DataCamp subscription, our Introduction to ChatGPT covers the same ground in 1 hour with hands-on exercises.

Best ChatGPT Course For Prompt Engineering

Prompt engineering is the practice of structuring a request so the model gives you a useful answer on the first try. These courses suit anyone who already uses ChatGPT and wants better, more consistent output.

1. Understanding Prompt Engineering

Our most-reviewed course on this list, and the fastest route to better prompts.

• Level: Beginner
• Time: 1 hour
• Cost: Included in a DataCamp subscription. The first chapter is free.
• Best for: Daily ChatGPT users who want reliable results

With 41,801 reviews and a 4.8/5 rating, this is the most-reviewed course in this article. It teaches the prompt patterns that make the biggest difference: clear instructions, examples, a role, and a specified output format.

It was updated in Aug 2026 and takes about 1 hour across 3 chapters. You can use what you learn in the next prompt you write.

2. Intermediate ChatGPT

The follow-on course once the basics feel easy.

• Level: Beginner
• Time: 1 hour
• Cost: Included in a DataCamp subscription. The first chapter is free.
• Best for: Users who want to understand why a prompt works, not only that it works

Intermediate ChatGPT explains how GPT models produce text, then moves to advanced prompt crafting. Knowing the architecture makes the odd failures easier to predict.

It takes about 1 hour and was last refreshed in Mar 2026. Our catalogue lists it at beginner level, so you do not need a technical background.

3. Prompt Engineering for ChatGPT (Vanderbilt University, on Coursera)

A university course taught by Jules White that goes much further into prompt patterns than a 1-hour course can.

• Level: Beginner
• Time: About 18 hours, per its Coursera listing
• Cost: Certificate requires a Coursera subscription
• Best for: Learners who want depth and a university name on the certificate

This is the longest course on the list by a wide margin. It works through a catalogue of reusable prompt patterns and builds up to complex, multi-step prompting.

The length is the trade-off. If you want to write better prompts this week, a 1-hour course gets you most of the way there.

Our pick: Take our Understanding Prompt Engineering first. If you want to go deeper, Vanderbilt's Prompt Engineering for ChatGPT is the most thorough option, at roughly 18 times the time.

Best ChatGPT Course For Custom GPTs And Workflows

A custom GPT is a version of ChatGPT set up with your own instructions and reference files for one repeated job. These courses suit people who keep pasting the same setup prompt into every new chat.

1. Introduction to GPTs

Our course on how GPT tools work and how to use them responsibly.

• Level: Beginner
• Time: 1 hour
• Cost: Included in a DataCamp subscription. The first chapter is free.
• Best for: Team leads who want a shared assistant everyone uses the same way

The course covers how GPT tools work, how to write prompts for them, and how to judge the output. It takes about 1 hour across 3 chapters, and was updated in May 2026.

With 1,088 reviews, it has the smallest review base of our ChatGPT courses, though the 4.8/5 rating is in line with the rest.

2. Agents and Workflows (OpenAI Academy)

OpenAI's course on handing structured, repeatable tasks to agents.

• Level: Intermediate
• Time: Self-paced
• Cost: Free with a ChatGPT account
• Best for: Learners who have finished a beginner course and want ChatGPT to do multi-step work

This course picks up where prompting stops. It covers delegating structured tasks so ChatGPT works through a sequence of steps rather than answering one message.

It comes from the company that builds the agent features, so it tends to cover new ones early.

Our pick: Start with our Introduction to GPTs, then take OpenAI Academy's Agents and Workflows for the agent features.

Best ChatGPT Courses For Your Job

A role-specific ChatGPT course teaches the prompts and workflows for one kind of work, using examples from that job. They are a better use of 3 hours than a general course if you already know the basics.

1. AI for Marketing

Our course on using AI for campaign planning and content.

• Level: Beginner
• Time: 3 hours
• Cost: Included in a DataCamp subscription. The first chapter is free.

• Level: Intermediate
• Time: 4 hours
• Cost: Included in a DataCamp subscription. The first chapter is free.
• Best for: Analysts who want AI to speed up the work without trusting it blindly

We are not quoting a star rating for this course. It has 137 reviews, below the 200 we require before we publish a score.

The course covers sharper prompts for analysis, auditing data quality, and checking AI output before it reaches a stakeholder. It takes about 4 hours and our catalogue lists it at intermediate level.

5. Introduction to SQL Querying with AI

Our course on writing and checking SQL with an AI assistant.

• Level: Beginner
• Time: 3 hours
• Cost: Included in a DataCamp subscription. The first chapter is free.
• Best for: Spreadsheet users who want to query a database without learning SQL from scratch

The course teaches you to describe the data you want in plain language, generate the query, and check it before you trust the result. It takes about 3 hours.

Our pick: Pick the course that matches your job title. If you work with data, take Introduction to SQL Querying with AI first, since it has the most reviews in this section.

Best ChatGPT Track

A track is a set of courses taken in order, which suits learners who want a structured path rather than choosing course by course.

1. ChatGPT Fundamentals

Our ChatGPT-only track, built from 3 of the courses above.

• Level: Beginner
• Time: About 3 hours
• Cost: Included in a DataCamp subscription. The first chapter is free.
• Best for: Learners who want one structured path through ChatGPT

The track runs Understanding ChatGPT, Understanding Prompt Engineering and Intermediate ChatGPT in order. Finish it and you have covered the basics, prompting and how the models work.

The rating is a review-weighted average across those 3 courses. The track page itself shows a score from only 14 reviews, which is too few to quote.

2. AI Fundamentals

Our broader track for people who want ChatGPT in the context of AI as a whole.

• Level: Beginner
• Time: About 9 hours
• Cost: Included in a DataCamp subscription. The first chapter is free.
• Best for: Learners who want to understand AI in general, not only one product

The track covers AI at work, machine learning, large language models, generative AI and AI ethics across 5 courses. It is longer than ChatGPT Fundamentals, and less about ChatGPT specifically.

Our pick: Take our ChatGPT Fundamentals track if ChatGPT is the tool you care about. Choose AI Fundamentals if you want the whole field.

Best Course For Building With The OpenAI API

The OpenAI API lets you call the models behind ChatGPT from your own code. These courses suit developers and data scientists who want ChatGPT inside an application rather than in a browser tab.

1. Working with the OpenAI API

Our first API course, and the most-taken developer course on this list.

• Level: Beginner
• Time: 3 hours
• Cost: Included in a DataCamp subscription. The first chapter is free.
• Best for: Python users making their first API call

With 180K learners, this is where most developers start. It covers the functionality behind applications like ChatGPT and has you calling the API within the first chapter.

You need some Python. It takes about 3 hours.

2. Prompt Engineering with the OpenAI API 

Our course on prompt engineering when the prompt lives in code.

• Level: Beginner
• Time: 4 hours
• Cost: Included in a DataCamp subscription. The first chapter is free.
• Best for: Developers who need consistent output from a production prompt

This course applies prompt engineering to GPT models through the API, where you cannot fix a bad answer by retyping. It is the longest of our individual courses here at 4 hours.

Its rating of 4.8/5 is from 4,575 reviews, refreshed in Jul 2026.

3. OpenAI Fundamentals

Our track that combines both courses above with embeddings, multi-modal models and the Responses API.

• Level: Beginner to intermediate
• Time: About 15 hours
• Cost: Included in a DataCamp subscription. The first chapter is free.
• Best for: Developers who want to build a full AI feature, not only call the model

The 5 courses go from a first API call to semantic search and audio. The rating is a review-weighted average across them, since the track page has no rating of its own.

4. ChatGPT Prompt Engineering for Developers (DeepLearning.AI)

A short course taught by Andrew Ng and Isa Fulford of OpenAI.

• Level: Beginner
• Time: About 1.5 hours, per DeepLearning.AI
• Cost: Free
• Best for: Developers who want a quick, free look before committing to a longer course

The course covers summarising, inferring, rewriting and expanding text through the API, and ends with a simple chatbot. The code runs in notebooks in the browser.

It is the fastest free starting point for developers. It is also short, so treat it as a taster rather than a full course.

Our pick: Developers short on time should take DeepLearning.AI's free short course first. For a full path from first call to working feature, take our OpenAI Fundamentals track.

Final Thoughts

Most people need 1 or 2 hours of training to get far more out of ChatGPT, not a long program. Start with our Introduction to ChatGPT, then Understanding Prompt Engineering.

After that, follow your use case. Pick a role course for your job, a custom GPT course for your team, or the OpenAI Fundamentals track if you write code.
