Prompt injection is text hidden inside content that a model mistakes for an instruction. The defense is not a cleverer model. It is a model with fewer powers.
A short explainer video, about a minute. It uses a story about a robot that summarizes a manager’s email.

What Prompt Injection Is
Prompt injection is text hidden inside content that a model mistakes for an instruction.
Why It Works
To a model, your instructions and the email arrive as one stream of text.
Why It Matters
To a model, anything it reads can look like an order.

The defense is not a cleverer robot. It is a robot with fewer powers.
