TL;DR

How much you can delegate to AI, and how much human review it needs, depends on the task and the model.

Tasks with few possible solutions and easy rollback are easier to delegate. Tasks with many possible solutions, product-policy implications, or long-term maintenance impact need human decision-making alongside AI.

This is not something you define once and forget. You need to use models from different vendors repeatedly and build a feel for how much you can trust each one in your own work.

AI capability and review depth are matters of intuition
