Prompt injection, a vulnerability where untrusted text within a language model's context window can be executed as instructions, is not a bug to be patched but a fundamental architectural flaw. Unlike jailbreaking, which aims to make a model say forbidden things, prompt injection targets a system's data by tricking the model into obeying malicious instructions embedded in external content. Effective defenses rely on architectural patterns, such as Simon Willison's Dual-LLM approach or Google DeepMind's CaMeL, which separate trusted instructions from untrusted data, preventing the model from confusing their sources.
