Secret Service gets its own private GPT-4 model that operates completely offline

Microsoft has developed a generative AI model for the U.S. Secret Service that can run without an Internet connection, Bloomberg reports. This is the first time a large-scale language model has been run completely isolated from the cloud, according to William Chappell, Microsoft’s CTO for strategic missions and technology. The company spent 18 months working on the system, rebuilding an AI supercomputer in Iowa specifically for the purpose. The static GPT-4 model can read files but cannot learn from them, a design choice intended to prevent classified information from leaking onto the platform. The service went live on Thursday and will now undergo testing and accreditation by the intelligence community. Chappell says the system is already capable of answering questions and writing code.
