Meta unveiled a new suite of tools named "Purple Llama" on December 7, aimed at securing and evaluating generated artificial intelligence (AI) models.
The toolkit, Purple Llama, intends to assist developers in safely constructing and reliably utilizing generative AI tools like Meta's open source model Llama-2. Meta's blog post explained that the term "Purple" in "Purple Llama" represents a blend of "Red Team" and "Blue Team."
Within the context of Purple Llama, Red Teaming involves developers or internal testers deliberately attacking AI models to identify bugs, glitches, or unintended outcomes and interactions. This approach aids in developing robust policies against malicious attacks, strengthening security measures, and ensuring safety.
Conversely, the Blue Team approach involves developers or testers responding to Red Team attacks. This enables them to determine strategies to counter real threats in production, customer-facing models, or consumer applications.
According to Yuan, a spokesperson for Meta, adopting both an offensive (Red Team) and defensive (Blue Team) stance is essential to addressing the challenges posed by generative AI. The concept of the Purple Team combines the responsibilities of both the Red and Blue Teams, offering an assessment and collaborative approach to mitigating potential risks.
Meta claims this release marks the industry's first comprehensive cybersecurity assessments of large language models (LLMs). This includes metrics designed to gauge cybersecurity risks associated with LLMs, tools to evaluate the frequency of unsafe code recommendations, and measures to make it tougher to generate malicious code or assist in cyberattacks.
The primary aim of these tools is to integrate them into the model pipeline, curbing undesirable output and unsafe code. Additionally, the tools aim to limit the exploitation of model vulnerabilities by cybercriminals and other malicious actors.
The Meta AI team stated, "With this initial release, our objective is to provide tools that address the risks outlined in the White House commitment."
