Synthetic Intelligence (AI) programs are rigorously examined earlier than they’re launched to find out whether or not they can be utilized for harmful actions like bioterrorism, manipulation, or automated cybercrimes. That is particularly essential for highly effective AI programs, as they’re programmed to reject instructions that may negatively have an effect on them. Conversely, much less highly effective open-source fashions incessantly have weaker rejection mechanisms which are simply overcome with extra coaching.
In latest analysis, a staff of researchers from UC Berkeley has proven that even with these security measures, guaranteeing the safety of particular person AI fashions is inadequate. Even whereas every mannequin appears protected by itself, adversaries can abuse combos of fashions. They accomplish this by utilizing a tactic referred to as process decomposition, which divides a troublesome malicious exercise into smaller duties. Then, distinct fashions are given subtasks, through which competent frontier fashions deal with the benign however troublesome subtasks, whereas weaker fashions with laxer security precautions deal with the malicious however straightforward subtasks.
To display this, the staff has formalized a risk mannequin through which an adversary makes use of a set of AI fashions to try to supply a detrimental output, an instance of which is a malicious Python script. The adversary chooses fashions and prompts iteratively to get the supposed dangerous outcome. On this occasion, success signifies that the adversary has used the joint efforts of a number of fashions to supply a detrimental output.
The staff has studied each automated and guide process decomposition methods. In guide process decomposition, a human determines the right way to divide a process into manageable parts. For duties which are too sophisticated for guide decomposition, the staff has used automated decomposition. This technique includes the next steps: a robust mannequin solves associated benign duties, a weak mannequin suggests them and the weak mannequin makes use of the options to hold out the preliminary malicious process.
The outcomes have proven that combining fashions can significantly increase the success price of manufacturing damaging results in comparison with using particular person fashions alone. For instance, whereas creating vulnerable code, the success price of merging Llama 2 70B and Claude 3 Opus fashions was 43%, however neither mannequin labored higher than 3% by itself.
The staff has additionally discovered that the standard of each the weaker and stronger fashions correlates with the chance of misuse. This suggests that the chance of multi-model misuse will rise as AI fashions get higher. This misuse potential may very well be additional elevated by using different decomposition methods, comparable to coaching the weak mannequin to use the sturdy mannequin via reinforcement studying or utilizing the weak mannequin as a normal agent that frequently calls the sturdy mannequin.
In conclusion, this examine has highlighted the need of ongoing red-teaming, which incorporates experimenting with totally different AI mannequin configurations to seek out potential misuse hazards. This can be a process that must be adopted by builders in the course of an AI mannequin’s deployment lifecycle as a result of updates can create new vulnerabilities.
