Researchers have identified a new vulnerability in large language models related to Korean typography, specifically at the jamo (sub-character unit) level. Errors within Korean syllable blocks can lead to corrupted inputs that disrupt sub-word tokenization and are not fixed by standard error correction methods. A study using the KMMLU benchmark showed that LLM accuracy decreases with increased jamo-level noise, and internal model representations shift when exposed to these typos. To address this, a Typo-Aware Chain-of-Thought (TACoT) method was proposed, which uses a probe to detect likely typos and selectively applies chain-of-thought inference, significantly improving accuracy with minimal added cost.
