In this video, I show you how I managed to bypass GPT-OSS’s alignment with a single, simple tweak—no fine-tuning or complex hacks required. I walk through how the model’s prompt template works, why removing it changes its behavior, and share my own tests replicating this jailbreak. This is purely for educational purposes so you can understand how alignment works under the hood.
