How to use ChatGPT 5
Step 1
Hand ChatGPT 5 the hardest version of your task: give it the full background, the goal, and every constraint, since it reasons best when it can see the whole problem at once.
Step 2
Ask it to think step by step, weigh tradeoffs, and surface assumptions before committing to an answer, which is where GPT-5's reasoning depth pays off over faster models.
Step 3
Use follow-ups to pressure-test the logic, request a more rigorous version, or have it turn the reasoning into a polished long-form deliverable.
