Anthropic has a new way to protect large language models against jailbreaks

Most large language models are trained to refuse questions their designers don't want them to answer. Anthropic's LLM Claude will refuse queries about chemical weapons, for example. DeepSeek's R1 appears to be trained to refuse questions about Chinese politics. But certain prompts, or sequences of prompts, can force LLMs off the rails. Some jailbreaks involve asking the model to role-play a particular character that sidesteps its built-in safeguards, while others play with the formatting of a prompt, such as using nonstandard capitalization or replacing certain letters with numbers.
