During testing, Hugging Face found that a Chinese open-source AI model was effective in defending against a simulated hack from an OpenAI model, where a US proprietary model's guardrails proved problematic. This incident highlights the power of Chinese models and the agility of open-source solutions.
“We learned some interesting fact about, uh, this, uh, sort of accidental hack that OpenAI models, uh, ran against the AI company Hugging Face during testing. And we learned that Hugging Face actually had tried to use a US frontier model to defend against this hack. But the guardrails came up. And so they used one of these Chinese open source models.”
“One, that they're very powerful and effective. And so the fact that they thought that they could rely on a Chinese model to basically do what a proprietary US model was going to help them with, reinforces the sense that they are not far behind of catching up. And then second is the usefulness of open weight, that, um, the way that the guardrails had been written on the proprietary model made it hard for them to defend. Uh, open source made it faster and easier, uh, and so that's what they relied on.”
