How AI Models Work

The steps are neat. The conclusion follows smoothly. It looks as though the AI carefully worked through the problem—but a convincing explanation can still rest on a hidden mistake. What people call AI “reasoning” is not the same as human thought. So what is the model actually doing when its answer appears logical?

The AI remembers your rule at the start of a conversation, then later repeats itself, changes direction, or acts as if the rule was never there. It is not choosing to forget. The earlier text may have slipped outside the model’s active view. What exactly is a context window, and why does it make long conversations less stable?
