5 Ways you are using ChatGPT-5 wrong

Key Takeaways

you are using GPT5 all wrong. Ever since its launch last month, people have been complaining about GPT5 being well just bad. Though its benchmark scores say completely the opposite. And to fill in the mismatch, OpenAI has now come out with a detailed GPT5 prompting guide. So what is going wrong? Most people treat GBT 5 like GBT4. Throw in a vague prompt and expect magic. But GBT5 doesn't just answer, it interprets. And if you leave gaps, it fills them in with assumptions you never asked for. That's why your results feel off. Here's the fix. First, be crystal clear. Don't just say summarize this. Say summarize in three bullet points under 50 words each, highlighting pros and cons. The more structured your ask, the sharper the output. Second, trigger the right mode. GPT5 has a thinking mode built for deep reasoning. Add prompts like think step by step or switch modes manually. Without this, you're leaving its best brain power unused. Third, don't ignore format. If you need JSON, tables, or exact wording, spell it out. GBD5 excels when it knows the container it's working in. Fourth, use examples. Few short prompting isn't a gimmick. It's your way of teaching the model how to behave. Show it the style once and it will replicate flawlessly. And finally, test your prompts. The prompt optimizer from OpenAI's cookbook can reveal hidden contradictions and polish your instructions for max efficiency. So, stop blaming the model. The power is already there. It's your prompting that needs an upgrade. Master that and GPT5 becomes unstoppable. We have added the link to OpenAI's prompt optimizer tool in the comments. Use it to master your prompts and make sure to save this video for the future and share it with your friends.
