Your own quote makes it clear. "When given the CVE description, GPT-4..."
GPT-4 is already pre-trained. "Pretrained" is literally the P in the name GPT. They used GPT-4, *combined with* the CVE descriptions. They didn't alter the training of GPT-4, 3, or the other models. If they altered the training of GPT-4, it would no longer *be* GPT-4, but a modified version of GPT-4.
Bing Copilot searches the internet to find documentation. This study provided the documentation via API. It's exactly the same thing, just different document sources fed into the API.
