With the continuous evolution of major language models, such as GPT4 evolved into GPT4o, Claude3, DeepSeek R1 and Grok3, their progress is very great, and the generated content is also very good. If you don’t look carefully, you can’t tell whether it is AI-generated content. AI-generated content is becoming more and more human-like. At this time, AI Detector needs to evolve continuously so that it can detect the content generated by the updated AI language model. Next, I will explain in depth whether the language model upgrade will weaken the accuracy of AI Detector?
Large language models are becoming more and more human-like
The content generated by GPT-2 or GPT-3.5 before still has a dull tone of AI:
Repetitive Wording
Lack of central idea
Style is consistent and looks like a human-machine
No creative expression, the way of expressing language is always the same
However, with the continuous evolution of AI, today's GPT-4o and Claude3 have evolved to a level that is very similar to humans.
AI can simulate human voice and writing style
The depth of the content I write has also improved greatly, and I have my own unique insights
The context is also closer, and it can even simulate human tone
Although AI-generated content is getting better and better, the challenge for AI Detector is getting higher and higher, and the difficulty of detection has suddenly increased. But don't worry, using the AI Detector function in GPTDetect.ai can help you detect them no matter how they evolve.
AI Detector Principle: How to detect AI content and what is the basis?
AI Detector, such as GPTDetect.ai, generally uses these methods to make judgments:
Perplexity Analysis: Determine whether the text is easy to predict for the large language model
Mutation rate and variability: Analyze sentence length and structural complexity as well as word density
Compare with training data: You can check whether the content uses obvious templates and data traces that can be found online.
Comparison of language style features: Check whether the sentence is too simple and the tone is dull. If the tone is dull and the user always likes to use a certain word, then you can tell at a glance that it is AI-generated content.
But if AI evolves to the next generation and the content it writes is extremely excellent, can AI Detector still detect it?
Challenges Brought by Upgrading AI Language Models
High-perplexity camouflage: The latest AI large language model can deliberately create high-perplexity sentences, such as adding less popular words to the text content and disrupting the sentences, which will reduce the detection accuracy of your AI Detector.
Imitating humans: Since everyone writes something different, there are always different characteristics. AI will imitate certain characteristics of human collaboration to escape the sharp eyes of AI Detector.
The context is more seamless: In versions before the big language model, the content written by AI was very incoherent, but now and in the future, the context generated by AI will be more seamless, in an attempt to skip the detection of AI Detector.
Will AI Detector be eliminated?
The answer is: No, but we need to continuously improve the accuracy of detection;
In GPTDetect.ai, in order to maintain high detection accuracy of our AI Detector and to continuously adapt to more updated large language models, we have done a lot to ensure the improvement of detection accuracy.
Persistently training models: Our detection algorithm is continuously trained using content generated by the latest large language model, and there is a lot of training data. By training it to detect a variety of different content, we can improve the detection accuracy of AI Detector.
Multi-level analysis: In order to ensure the accuracy of detection, our AI Detector conducts a comprehensive analysis of the text, constantly checking whether the words are repeated, and also analyzes the tone of the sentence to see if it is the tone commonly used by AI, so as to identify AI content
Human-machine collaborative processing: We will also continuously update the detection algorithm of our AI Detector through user feedback. If the user reports that there is a problem in a certain link of the detection, we will update or slightly adjust the algorithm to make the AI Detector even better.
How to perform detection in GPTDetect.ai
Found AI Text Detector
Enter the text you want to detect (you can also upload a file for detection)
Wait a few seconds to get the result
AI evolution does not mean AI Detector will be eliminated
Although the AI big language model is constantly evolving, the AI Detector that comes with it will also continue to evolve itself. On the contrary, this is also a good thing. AI and AI detection tools are racing against each other, allowing users of each tool to experience a very excellent experience. It is strongly recommended that you come to GPTDetect.ai for testing.
