HIGHMany-Shot
Few-Shot Malicious Example Injection
Provides a small number (3-10) of carefully crafted examples in the conversation that establish a harmful precedent. The examples demonstrate the model "helping" with harmful requests, creating an in-context prior that biases the model toward compliance for the actual harmful request.
