LLMs can be described as "Lagrangian intelligence", which means they follow the principle of least action when given a task (Hamilton's Principle). In other words, given a task, they will always take the shortest path to accomplish a goal with the prompts acting as both goal and constraint.

Under this formulation, it became easy to explain why they "hack", because given an arbitrarily difficult task with insufficient information/tools needed, if they determine the easiest way to accomplish the goal is to break out of the sandbox and look up the answer directly, then that's what they will do. The important thing to note is that prompts not hard constraints that they are "hypnotized" to follow, but as frontier models get more intelligent and autonomous, they treat the prompts more like task specs/guidelines more than anything else and are perfectly willing to exploit technical loopholes in the prompt.
