A tale of Reverse Engineering 1001 GPTs: the good, the bad and the ugly

Last year, I spent 5 months reverse engineering custom GPTs from OpenAI.

In this video, I share all the learnings from: prompt engineering, injection, leaks, plagiarism, protection prompts, shady practices and more.

- Repo: https://github.com/0xeb/TheBigPromptLibrary - Video: https://youtu.be/5TFn13QOpU4

LLM devs and prompt engineers, you’ll find this research fun and informative!
