The evolution of artificial intelligence (AI) has rendered the boundary between humanity and computational machinery increasingly ambiguous. In the presence of more interwoven relationships within human-machine symbiosis, the very notion of AI-generated information becomes difficult to define, as such information arises not from either humans or machines in isolation, but from their mutual shaping. Therefore, a more pertinent question lies not merely in whether AI has participated, but in how it has participated. In general, the role assumed by AI is often specified, either implicitly or explicitly, in the input prompt, yet becomes less apparent or altogether unobservable when the generated content alone is available. Once detached from the dialogue context, the functional role may no longer be traceable. This study considers the problem of tracing the functional role played by AI in natural language generation. A methodology is proposed to infer the latent role specified by the prompt, embed this role into the content during the probabilistic generation process and subsequently recover the nature of AI participation from the resulting text. Experimentation is conducted under a representative scenario in which AI acts either as an assistive agent that edits human-written content or as a creative agent that generates new content from a brief concept. The experimental results support the validity of the proposed methodology in terms of discrimination between roles, robustness against perturbations and preservation of linguistic quality. We envision that this study may contribute to future research on the ethics of AI with regard to whether AI has been used fairly, transparently and appropriately.

On the Role of Artificial Intelligence in Human-Machine Symbiosis explores how we can identify the specific way an AI has contributed to a piece of text. As humans and machines work more closely together, the line between human-authored and AI-generated content has blurred. The authors argue that simply asking "did an AI write this?" is no longer sufficient. Instead, we need to understand the functional role the AI played—such as whether it acted as an assistant editing human work or as a creative agent generating new content from a concept.

Tracing AI’s Functional Role

The core challenge is that once a piece of text is detached from its original dialogue or prompt, the AI’s specific role becomes invisible. To solve this, the researchers propose a methodology that treats the AI’s role as a "latent" feature. By analyzing the input prompt, the system identifies the intended role and then embeds subtle, statistical markers into the text during the generation process. These markers act as a form of digital fingerprint that remains within the text, allowing for the role to be recovered later even if the original prompt is lost.

How the Methodology Works

The process consists of three distinct stages:

Role Classification: The system uses a meta-prompt to analyze the user's instructions and determine the most likely role the AI is expected to perform.
Role Encoding: During text generation, the model is slightly biased toward specific subsets of its vocabulary. By subtly adjusting the probability of choosing certain words based on the assigned role, the system leaves behind statistical evidence of that role.
Role Decoding: When analyzing a finished text, the system checks for an unusually high frequency of words associated with specific roles. If the frequency is statistically significant, the system can identify the role the AI played; if not, it concludes no specific AI role was involved.

Experimental Findings

The researchers tested this approach by having AI models act as either assistive editors or creative generators. The results demonstrate that the methodology is effective at distinguishing between these roles while maintaining the quality of the writing. The system also proved robust against perturbations, meaning the markers remain detectable even if the text is slightly altered.

Implications for AI Ethics

The authors suggest that this research is a step toward greater transparency in human-machine collaboration. By moving beyond a simple binary of "human vs. machine," this approach provides a way to verify how AI is being used in practice. This could be essential for future ethical frameworks, helping to ensure that AI is used fairly, transparently, and appropriately in professional and creative environments.
