Technique Effectiveness

This technique is highly effective for observing how professional Prompt Engineers structure their instructions. However, it may not be 100% successful if the GPT creator has implemented 'protection prompts' to prevent information leaks.

Usage Ethics

Use this technique solely for reference and learning purposes. Do not use extracted information to unethically clone or launch competing products.

OpenAI Update Risks

OpenAI frequently updates its systems to close loopholes like this. If this prompt no longer works, you may need to search for newer 'jailbreak' prompt variations on platforms like X (Twitter) or within AI communities.
