Upstage's Solar Pro 4 goes live on government AI infrastructure
Solar Pro 4 is delivered through Samsung SDS's FabriX platform and runs on administrative-network servers that passed a spy agency security review.
Upstage said on November 3, 2026, that its Solar Pro 4 large language model has been deployed on the government-wide common AI infrastructure and has begun formal service.
The model is provided through Samsung SDS's AI platform FabriX and runs on administrative-network infrastructure that passed a security review by the National Intelligence Service. According to digitaltoday.co.kr, agencies can use the model through a chat interface or an API without building their own GPU servers.
Solar Pro 4 supports answers grounded in internal data such as statutes, press releases and administrative work materials. Upstage lists the main uses as checking ordinance and regulation revisions for conflicts with higher law, drafting responses to civil complaints, writing reports from meeting materials and summarizing long policy documents.
Built for Korean-language document work
Solar Pro 4 is Upstage's own model, unveiled in August 2026, which the company describes as specialized for Korean language and document processing.
Public institutions had previously struggled to use internal data with external AI services because of security concerns, and faced a burden in building their own GPU infrastructure.
