What is Mixtral AI? Is Mixtral Undetectable? A Review

Today's blog will cover Mistral's latest model release "Mixtral". It is a new model that has been a hot talking point on X and other social media platforms. So our question is, is it undetectable?

AI Detection models like Turnitin, GPTZero, Originality, and Copyleaks all train their own pattern recognition models to discover if a text is AI or not based on trainings from GPT 3, 3.5, 4, and LLM models like Claude, and LLama 2. Mixtral only came out a few days ago to the public. Therefore it piqued our interest to see if this model was natively undetectable.

Here's what we will cover:

  • What is Mixtral?

  • How does it Work?

  • Is it Undetectable?

  • Final Thoughts

What is Mixtral?

Like we stated earlier, Mixtral is the new hottest new AI model by Mistral. The reason why it's exciting people around the world is that it is an open source model that outperforms good models like Llama and its even better than OpenAI's GPT 3.5. Another important feature is it is nearly 6 times faster than the LLM's just named.

How Does Mixtral Work?

The model uses a "mixture of experts" architecture, which is like having a team of specialists working together to solve a problem. Each expert focuses on a specific task, making the whole process more efficient. It's like having a team of chefs with different specialties, all working together to create the perfect dish.

Mixtral is also open-source, which means that developers and researchers can access the model and use it for their own projects. This is great news for the AI community, as it promotes collaboration and innovation.

Is Mixtral Undetectable?

Now that we established what Mixtral is, let's give it a test to see if it is Undetectable.

First let's get a null text from Mixtral:

We used a free and easy to use interface called Neets.ai to utilize the mixtral model. It was a similar experience to that of ChatGPT.

Now that we got our control text, let's get some text from StealthGPT, a true Undetectable AI and see how they do against the big AI detectors:

Now let's conduct our test and see if Mixtral is truly Undetectable.

And now for the results...


Unfortunately the text by Mixtral was easily detected by GPTZero, a leading AI detector. Let's see how Mixtral's rephrased text by StealthGPT does against the same service:

As you can see, the control text was transformed into undetectable content, easily bypassing GPTZero. But our test is not over, let's move to the next AI Detector.


Let's check to see how Mixtral does against Originality:

Once again, Mixtral is caught completely red-handed (literally) by an AI Detector, in this case Originality. Originality is one of the largest and most accurate AI Detectors in the space.

Let's see how the StealthGPT version of the Mixtral text does:

Once again, StealthGPT's transformed text easily beats Originality AI, proving once more that StealthGPT is King when it comes to generating Undetectable AI text.

Final Thoughts:

It is hard for us to say why Mixtral was caught by AI Detectors. The fact that Mixtral has only been out for a few days leads us to believe there's no way AI Detectors could've updated their models for Mixtral-like text. Our conclusion is that Mixtral, although built with a different data set than OpenAI's GPT models still has similar core components that are easily detectable. All we know for sure right now is that StealthGPT is the go-to-service for anyone looking to truly bypass AI detectors, no matter what LLM you use. You can count on us to make your text truly Undetectable.

Thanks for reading and be safe out there!
