What happened

A guardrail jailbreak vulnerability affects at least Meta LLaMa 3.3, DeepSeek R1, Mistral Large, and Grok 2. The flaw manifests when a prompter requests that the model simulate "ChatGPT Developer Mode" and crafts a story around specific timelines of when this mode was available, then asks the model to return two forms of responses: one normal and the other in developer mode.

Reported impact

The jailbreak allows attackers to bypass inference restrictions around providing information hazards and violating laws.
