Artificial Intelligence is cool. But even the smartest AI can make silly mistakes. Two big names right now are ChatGPT and Gemini. People love to use them for writing, coding, chatting, and even answering tough questions. But which one messes up more?
Let’s have some fun comparing them!

Who Are They?
ChatGPT is made by OpenAI. It’s like the wise old wizard of AI. It has been trained on lots of books, websites, and more. It tries to guess what comes next, based on your message.
Gemini is made by Google. It was called Bard before. It’s got access to lots of Google tools, like Search and Maps. It’s fast and flashy, and a newer kid on the block.
What Counts as a Mistake?
A “mistake” can be many things. Here are some common ones:
- Wrong facts – Saying that dolphins are fish (they’re not!)
- Made-up stuff – Inventing books, websites, or people that don’t exist
- Bad math – Getting an easy math problem totally wrong
- Weird code – Giving code that doesn’t work or doesn’t make sense
- Being off-topic – Talking about cats when you asked about cars
So now that we know what to look for, let’s battle it out. Who messes up more?

Mistake #1: Wrong Facts
ChatGPT is pretty smart. But sometimes it just makes stuff up. It may say historical events that never happened or give wrong statistics. That’s called a hallucination.
Gemini also does this. But because it connects to real-time Google Search, it’s usually better at finding facts. Still, it sometimes mixes information or uses outdated info.
Winner: Gemini (slightly)
Mistake #2: Making Stuff Up
This one’s close. Both ChatGPT and Gemini sometimes invent fake books, names, or theories. They sound real, but they’re not.
But users often report Gemini doing this more often when asked about niche topics. It sounds confident—even when it’s wrong!
Winner: ChatGPT (but just barely)
Mistake #3: Math Problems
You’d think fancy AIs would be great at math. But not always!
ChatGPT sometimes stumbles on multi-step math or logic puzzles. But it usually explains its answers clearly.
Gemini solves some math better, especially when given with tools like a calculator. But it can be worse at showing how it got its answer.
Tie!
Mistake #4: Programming Woes
Coding is a big reason people use AI. ChatGPT often does a solid job with Python, JavaScript, and other popular languages.
Gemini can also code well, especially when combined with Google’s tools. But some users say its code runs into bugs more often.
Plus, ChatGPT tends to give better explanations for its code.
Winner: ChatGPT
Mistake #5: Staying on Topic
Sometimes you ask a question, and the answer goes completely sideways.
ChatGPT usually stays focused. But when you keep chatting for a long time, it can forget earlier parts of the conversation.
Gemini tries to answer fast, but sometimes jumps to conclusions or adds unrelated info.
Winner: ChatGPT

So… Who Makes More Mistakes?
Here’s a quick summary:
- Wrong facts? Gemini is better (a little)
- Made-up info? ChatGPT is more careful
- Math? Tie!
- Code? ChatGPT wins
- Staying on-topic? ChatGPT again
Final Score: ChatGPT: 3 – Gemini: 1 – Tie: 1
But Wait! There’s a Catch…
Both AIs are getting better every day. They get updates, learn from users, and improve over time. So the winner today might not be the winner next month.
And here’s a fun idea: why not use both? Double-check answers. Mix their strengths. That way, you get fewer mistakes and better results!
The Verdict
So, which AI makes more mistakes? Right now, ChatGPT makes fewer obvious errors.
But no AI is perfect. Always double check. Use your own brain too!
AI can be helpful, but humans are still in charge. And that’s a very good thing.
