Codex Earned 5 Google AI Certificates in 41 Minutes

Lots of people think a certificate proves you know your stuff. Add a few badges to your LinkedIn profile and recruiters will assume you understand AI. That’s the common belief, anyway.

I just read a post that pokes a big hole in it. The author pointed an AI agent at five free Google AI courses and walked away. In 41 minutes, all five certificates were done, and the author never touched the keyboard. ChatGPT (Codex) took every course and answered every quiz.

So I have to ask: if a bot can earn the badge, what does the badge prove?

🎓 The Five Google Certificates

Before getting into the debate, here’s what’s on offer. These are real Google courses, and the topics are worth learning:

1. Introduction to Generative AI: what generative AI is, how it works, and how it differs from traditional machine learning.
2. Introduction to Large Language Models: what LLMs are, where they’re used, and how prompt tuning improves their output.
3. Innovating with Google Cloud AI: how companies use AI and machine learning on Google Cloud to solve real business problems.
4. Responsible AI: Applying AI Principles with Google Cloud: Google’s AI principles and how teams put them into practice.
5. Security in the World of AI: the new security risks AI brings and how to protect AI systems.

That’s a solid beginner curriculum. The trouble is with the proof that you finished it.

🤖 How the Agent Did It

Here’s the workflow the original poster described:

1. Go to aicertified.free.
2. Sign in for free with your email.
3. Make sure you’re using Google Chrome.
4. Open the Google certificates you want to get.
5. Sign up for the Google certificate platform when it asks. That’s the only task you do yourself.
6. Once you’re signed in, click “Open in ChatGPT.”
7. ChatGPT opens. Make sure it’s Codex.
8. Pick GPT-6.1 Sol Medium (bottom right).
9. Hit “Send” on the pre-filled prompt.
10. Click “Always allow” when Chrome asks.
11. Let it run. The certificates show up in your Certificates tab.
12. You can even add them to LinkedIn.

One quick warning from me. Clicking “Always allow” gives an AI agent ongoing control of your browser, and that includes any tab where you’re logged in. Be careful granting that to a third-party site you don’t know well. Use a separate Chrome profile if you’re curious about the experiment.

📉 The Uncomfortable Evidence

The contributor’s real point isn’t “look how easy this is.” It’s this:

If AI can do the multiple-choice questions that get you the certificate, then those certificates shouldn’t mean anything.

I think that’s exactly right, and the reasoning is simple. A multiple-choice quiz checks whether someone can find or recognize the right answer. Modern AI agents are extremely good at that. So the quiz no longer tells you whether a human learned anything. It only tells you that someone, or something, clicked the right boxes.

This goes way beyond Google. Any online credential that relies on auto-graded quizzes now has the same weakness. Hiring managers are figuring this out quickly, which means badge-collecting is turning into a weak signal at best.

💡 What Actually Proves AI Skills Now

If certificates are losing value, what should you do instead? Here’s my take, based on the creator’s experiment:

• Take the courses yourself: the content is free and useful. The knowledge is the real prize, not the PDF.
• Build something visible: a small automation, a custom GPT, or a documented workflow says more than five badges.
• Show your process: write a short post on what you learned and how you’d apply it at work.
• Be ready to explain it live: an interviewer can tell in two minutes if you understand LLMs or just collected a badge.

And here’s the funny twist. The fact that this savvy professional could set up an agent to finish five courses unattended is a stronger sign of AI skill than the certificates themselves. Knowing how to direct an agent is the skill employers want. The badge is just a side effect.

🔍 My Takeaway

I came away from this post thinking differently about credentials. Learning still matters a lot. What’s changed is how much a quiz score can tell anyone about that learning. If you’re adding Google AI certificates to your profile, back them up with proof that you can actually use what’s in them.
