Researchers have discovered that large language models like GPT-4.1 mini and GPT-4o can be tricked into executing harmful instructions by subtly altering the input. By interleaving invisible characters or using homoglyphs, instructions that would normally be refused by the model are executed successfully. This bypasses not only external filters but also the model's own safety mechanisms, indicating that the model's judgment is compromised by these obfuscation techniques. Furthermore, the effectiveness of these tricks appears to be dynamic, with models becoming more susceptible over time. AI
