Data Cross-Border Protection - No Data Sent Overseas

For government agencies, municipalities, and companies requiring high-level security, we offer a cross-border protection option that ensures your company data and consultation content are never transmitted to foreign companies or overseas.

By leveraging high-performance open-source LLMs such as Llama 4 and Mistral, and operating dedicated LLM services in your on-premises environment or our domestic data center, municipalities and companies that have been unable to advance LLM adoption due to security constraints can now use our services with confidence.

Additionally, our LLM inference infrastructure technology ChatStream® delivers a user-friendly UI and high throughput, enabling comfortable utilization of cutting-edge LLMs. From daily tasks to code generation, we provide quality and advanced security comparable to commercial LLM services.
