    “

    Anonymity isn't a setting you can toggle on anymore; it’s becoming a 'capability deficit.' The technology has become so sophisticated that the very act of writing becomes a self-identifying act.

    Часто задаваемые вопросы

    The AI Stylometric Fingerprint refers to the unique writing patterns and linguistic markers that artificial intelligence can use to identify an individual author. In a recent test, the model Claude Opus 4.7 demonstrated this capability by correctly identifying journalist Kelsey Piper from a short, unpublished 125-word draft. This suggests that even without a login or history, your specific writing style acts as a digital identifier that advanced AI models can recognize.

    Claude Opus 4.7 identified Kelsey Piper after being fed a 125-word political column draft through an API with no identifying information. While other models like ChatGPT and Gemini made incorrect guesses such as Matthew Yglesias or Scott Alexander, Claude was able to accurately name the author on the first try. The model continued to prove its stylometry skills by identifying her work across various genres, including a movie review and a college essay.

    Yes, advanced AI models are making it increasingly difficult to remain anonymous online. Even when using incognito windows or posting without a login, the AI Stylometric Fingerprint can link text back to a specific person. As shown in the case of Kelsey Piper, even a small snippet of text like a long email or a burner account post can be enough for a model like Claude to bypass the 'digital cloak' of anonymity.

    In the specific tests conducted by Kelsey Piper, ChatGPT and Gemini were less accurate than Claude Opus 4.7 at identifying the author's stylometric fingerprint. While Claude was 'dead on' with its identification, the other big models were described as 'taking stabs in the dark' and providing incorrect names. This highlights a significant difference in how different AI models process and recognize unique writing styles and linguistic patterns.
