Japanese-language LLM research and development with production ML infrastructure

Technology, Information and Internet 港区, 東京都 51–200 employees Public Company

SB Intuitions is a public R&D company building large-language models optimized for Japanese. The tech stack reveals deep ML infrastructure maturity: vLLM, SGLang, TensorRT-LLM for inference optimization; Kubernetes, Docker, Terraform, CloudFormation for orchestration; and multi-cloud deployment across GCP, AWS, Azure. The project backlog—Sarashina model deployment, petabyte-scale data management, multi-datacenter integration, and incident response—maps directly to the pain points (LLM scaling, data governance, network security), indicating an organization moving from research prototype to production systems.
