Prompt injection in LLMs is an architectural problem, not merely a security bug, because systems process trusted instructions and untrusted data within the same context window. Traditional filtering methods are insufficient as attackers can hide malicious instructions within external content like webpages or documents, which the LLM treats as just another sequence of tokens. Addressing prompt injection requires a shift from defensive prompting to fundamental architectural design that establishes clearer trust boundaries. AI
