Improbable Bigrams Expose Vulnerabilities of Incomplete Tokens in Byte-Level Tokenizers (2025.emnlp-main)
Copied to clipboard
| Challenge: | Recent studies have revealed that tokenizers can be exploited to elicit unwanted behavior. |
| Approach: | They propose to exploit incomplete tokens with stray bytes to exploit their dependency . they propose to use improbable bigrams to exploit the dependency of their adjacent tokens . |
| Outcome: | The proposed tokenizers can be exploited to elicit unwanted behavior in language models. |
