A Study Reveals Alarming Similarity Between DeepSeek and ChatGPT Outputs
The world of artificial intelligence has been abuzz with the recent findings of a study conducted by Copyleaks, a company specializing in AI detection technology. The study revealed that a staggering 74.2% of DeepSeek’s written text is stylistically similar to OpenAI’s ChatGPT outputs, fueling the ongoing debate over the intellectual property (IP) rights of training data. This discovery has far-reaching implications for the AI industry, and it remains to be seen how this will impact the development and deployment of language models.
The Study Methodology
To conduct their research, the Copyleaks team employed a combination of screening technology and three AI classifiers. These classifiers were designed to identify subtle stylistic features in text, such as sentence structure, vocabulary, and phrasing. The team applied these classifiers to texts from various AI models, including Claude, Gemini, Llama, and OpenAI. The results revealed that the classifiers achieved a 99.88% precision rate and a mere 0.04% false-positive rate, accurately identifying texts from both known and unknown AI models.
The Findings
When the Copyleaks team applied their classifiers to DeepSeek-R1, they found that an astonishing 74.2% of the generated text aligned with OpenAI’s stylistic fingerprints. This finding was in stark contrast to Microsoft’s Phi-4 model, which demonstrated a 99.3% disagreement rate. The researchers concluded that this similarity is not coincidental and raises concerns about DeepSeek’s potential reliance on OpenAI’s output.
The Implications
The implications of this study are far-reaching and have significant consequences for the AI industry. If DeepSeek has indeed been trained on OpenAI’s data, it could be seen as a case of intellectual property infringement. The researchers suggest that this potential undisclosed reliance on existing models could lead to biases being reinforced, limit the diversity of responses from language models, and pose legal or ethical risks.
A Breakthrough in Tracking IP
The Copyleaks team believes that their research has led to a breakthrough in tracking AI model-specific attribution. This capability is crucial for improving transparency, ensuring ethical AI training practices, and protecting intellectual property rights. Shai Nisan, Chief Data Scientist at Copyleaks, emphasizes the significance of this development: "This is a breakthrough that fundamentally changes how we approach AI content. This capability is essential for multiple reasons, including improving overall transparency, ensuring ethical AI training practices, and, most importantly, protecting the intellectual property rights of AI technologies."
The Future of AI Development
The findings of this study have significant implications for the future of AI development. If AI companies are found to be relying on each other’s data without proper disclosure, it could undermine their claims of innovation and creativity. The researchers suggest that this could lead to a re-evaluation of how AI models are developed and deployed.
Conclusion
The Copyleaks study has shed new light on the world of AI development, revealing potential vulnerabilities in IP protection and AI model attribution. As the industry continues to evolve, it is essential to prioritize transparency and ethics in AI development. The findings of this study serve as a reminder that the line between innovation and imitation can be thin, and it remains to be seen how the AI industry will respond to these revelations.
