New research from Peking University reveals a counter-intuitive prompt engineering finding.

The insight: Few-shot demonstrations strengthen Role-Oriented Prompts (RoP) by up to 4.5% for jailbreak defense. Same technique degrades Task-Oriented Prompts (ToP) by 21.2%.

The mechanism: Role prompts establish identity. Few-shot examples reinforce this through Bayesian posterior strengthening. Task prompts rely on instruction parsing. Few-shot examples dilute attention, creating vulnerability.

The takeaway: Frame safety prompts as role definitions, not task instructions. Add 2-3 few-shot safety demonstrations. Avoid few-shots with task-oriented safety prompts.

Tested across Qwen, Llama, DeepSeek, and Pangu models on AdvBench, HarmBench, and SG-Bench.

Собственный контент-фильтр на базе LLM: от эксперимента до стабильной системы

Привет! Меня зовут Миша Мартьянов, я инженер по исследованиям и разработке в red_mad_robot. Моя работа — искать новые идеи, проверять гипотезы и улучшать продукты. На этом пути иногда приходится изобретать уникальные решения. Например, мы создали собственный фильтр, чтобы отсеивать нежелательный контент с помощью LLM. Рассказываю, как мы к этому пришли и с какими сложностями столкнулись.
