AI determines nationality by punctuation mark

Users discovered that ChatGPT and Claude neural networks can automatically switch to another language when using specific punctuation marks. This phenomenon allows AI to determine the user's nationality by a single character.

Experiments with language models

Two enthusiasts tested this feature in practice. When entering a Chinese comma, ChatGPT responded in Chinese. A similar experiment with Claude led to the model switching to Japanese.

Limitations for Russian-speaking users

For Russian-speaking users, this method of determining nationality through punctuation does not work, as the standard comma is not a unique language marker in the context of these models.
