Let it think.

“Think step by step” used to be a trick. Many models now reason on their own. The skill is knowing when thinking helps, and asking to see it.

Standard models

Ask For The Working

For maths, logic or multi-part problems, ask it to work through the steps before giving the answer.

Reasoning models

Give Goals, Not Scripts

They already think before answering. Give the goal and the constraints, and skip micromanaging each step.

Either way

Make It Checkable

Ask it to list its assumptions and show key calculations, so you can spot where it went wrong.
