AI services company ESTsoft, led by CEO Sang-won Jung, announced on the 20th that it has won a contract to build an in-house generative AI language model (sLLM) for the Jeju Free International City Development Center (JDC).
The six-month project will deploy generative AI on JDC’s internal servers to improve staff accuracy and efficiency. Security and privacy requirements limit the use of institutional data with external AI services, making a secure, isolated environment central to the project.
ESTsoft will combine an on-premises sLLM with AI agents, connecting knowledge across JDC so employees can quickly find reliable information and make evidence-based decisions.
Specialized chatbots will support development projects, duty-free operations, budgeting, safety, contracts, and HR. Models with at least 30 billion parameters will handle routine queries, while models with at least 120 billion parameters will support complex reasoning over long texts.
Approximately 3.8 TB of internal documents will be embedded for retrieval-augmented generation (RAG), enabling AI-powered document search. Integration with existing systems, including enterprise content management (ECM), and external data will keep responses current.
Beyond answering questions, API-driven agents will execute tasks. An agent builder will let JDC design and run workflows involving multiple agents, enabling it to expand AI adoption independently.
Security, monitoring, and LLMOps tailored to the isolated network will support reliable, sustainable operations. With accuracy essential to public-sector work, the platform will provide supporting documents alongside answers and carry out tasks to deliver practical efficiency gains.
ESTsoft will apply capabilities proven through its agentic AI service Alan, AI orchestration expertise that delivers strong performance with limited resources, and nearly three decades of cybersecurity experience.
Following recent projects in agriculture and defense, the contract further expands ESTsoft’s sLLM and AI agent business in the public sector.
“This project will demonstrate how public institutions with strict security requirements can use generative AI safely and effectively,” said Sang-won Jung, CEO of ESTsoft. “Drawing on the agentic AI capabilities developed through Alan, we will help JDC transform its operations and accelerate our growth in the public-sector AI market.”
