The ChatGPT Prompts: 9 Rules That Will Make AI Work for You

Disclosure: I use GPT search to collection facts. The entire article is drafted by me.

The difference between getting mediocre AI output and exceptional results often comes down to one simple thing: how you ask. It’s not magic — it’s engineering.

OpenAI released new data in 2025 showing that GPT-5 achieves a 91.4% accuracy rate on the MMLU benchmark, yet here’s the kicker: the same model can perform at just 25% accuracy on the same task with poorly structured prompts. That’s not a technology problem. That’s a communication problem. And communication is something you can control right now.​

This isn’t another theoretical guide. What follows are rules that work — tested against real datasets, refined by practitioners across industries, and backed by 2025 research showing that 78% of AI project failures stem directly from poor human-AI communication. But the flip side? Teams that master prompting report 340% higher ROI compared to ad-hoc approaches.​

Let’s talk about the actual rules that make ChatGPT do what you want.

Rule 1: Be Specific About What You Want, Not Vague About It
