GPT-5 prompting guide

• We’ve seen significant gains from applying these best practices and adopting our canonical tools whenever possible, and we hope that this guide, along with the prompt optimizer tool we’ve built, will serve as a launchpad for your use of GPT-5. But, as always, remember that prompting is not a one-size-fits-all exercise – we encourage you to run experiments and iterate on the foundation offered here to find the best solution for your problem.
