Large language models like ChatGPT face security challenges from adversarial attacks and jailbreak prompts that can bypass safety measures implemented during alignment processes like RLHF. Unlike image-based attacks that operate in continuous space, text-based adversarial attacks are more challenging due to the discrete nature of language and lack of direct gradient signals.
