Summary

The video is a tutorial by Renaud Dékode on using OpenAI’s Prompt Optimizer to improve prompts for GPT-5. The creator explains that GPT-5 requires a different prompting approach and criticizes the sale of ‘magic prompts’ as scams. He demonstrates how to access the tool via the OpenAI platform (not ChatGPT), paste an existing prompt, and let the optimizer rewrite it in a more structured and effective way. The video highlights the importance of structuring prompts with role, task, objective, context, constraints, and format. The creator shows a side-by-side comparison of the original and optimized prompts, and then tests both with GPT-5, noting that the optimized prompt yields better results. He emphasizes that the ‘review changes’ feature is particularly valuable as it explains why each change was made, helping users learn better prompting habits. The video concludes with an invitation for viewers to share their experiences.
