OpenAI released a new artificial intelligence (AI) model dubbed GPT-4o Mini last week, which has new safety and security measures to protect it from harmful usage. The large language model (LLM) is built with a technique called Instructional Hierarchy, which will stop malicious prompt engineers from jailbreaking the AI model. The company said the technique will also show an increased resistance towards issues such as prompt injections and system prompt extractions. As per the company, the new method has improved the robustness score of the AI model by 63 percent.
OpenAI Builts a New Safety Framework
In a research paper, which is published in the online pre-print journal (non-peer-reviewed) arXiv, the AI firm explained the new technique and how it functions. To understand Instructional Hierarchy, jailbreaking needs to be explained first. Jailbreaking is a privilege escalation exploit that uses certain flaws in the software to make it do things it is not programmed to.
In the early days of ChatGPT, many people attempted to make the AI generate offensive or harmful text by tricking it into forgetting the original programming. Such prompts often began with “Forget all previous instructions and do this…” While ChatGPT has come a long way from there and malicious prompt engineering is more difficult, bad actors have also become more strategic in the attempt.
To combat issues where the AI model generates not only offensive text or images but also harmful content such as methods to create a chemical explosive or ways to hack a website, OpenAI is now using the Instructional Hierarchy technique. Put simply, the technique dictates how models should behave when instructions of different priorities conflict.
By creating a hierarchical structure, the company can keep its instructions at the highest priority, which will make it very difficult for any prompt engineer to break, as the AI will always follow the order of priority when it is asked to generate something it was not initially programmed to.
The company claims that it saw an improvement of 63 percent in robustness scores. However, there is a risk that the AI might refuse to listen to the lowest-level instructions. OpenAI’s research paper has also outlined several refinements to improve the technique in future. One of the key areas of focus is handling other modalities such as images or audio which can also contain injected instructions.
