GPT-6 Astra reportedly jailbroken within 24 hours using extended TIP attack

A researcher reports jailbreaking GPT-6 Astra within a day of its release, by combining the TIP (Task-in-Prompt) attack from their ACL 2025 paper with four other unnamed techniques. TIP exploits the model's reasoning/instruction-following behavior by hiding the harmful objective inside another task, such as solving a cipher or executing Python code. The researcher says the original minimal TIP attack no longer worked on GPT-6 and had to be reworked. Details were disclosed privately to OpenAI rather than published. The same researcher jailbroke GPT-5 within an hour of its release a year ago.
