LY Corporation needed to modernize flagship consumer platforms and internal operations with AI while safely handling large volumes of user and enterprise information and maintaining trust in user-facing experiences.
Reported impact
LY Corporation created 32 AI-driven use cases, cut hundreds of thousands of work hours through internal productivity gains, improved consumer search and assistant experiences, and projected material revenue and productivity upside from AI-powered features.
LY Corporation built a shared OpenAI-powered foundation for both employee productivity and consumer-facing product features. Internally, the company rolled out SeekAI, an in-house tool built on the OpenAI API that uses retrieval-augmented generation over internal workspaces and documentation databases to answer employee questions quickly and reduce verification work across departments. Externally, LY uses GPT-4o in the LINE AI Assistant so users can access conversational help inside the messaging app they already use every day, and it added GPT-4 and GPT-4o features to Yahoo! JAPAN Search to summarize reviews and generate travel plans. The rollout was wrapped in governance, ethics, and employee-education controls, including zero-data-retention guarantees and clear rules around model inputs and outputs, enabling 32 production use cases by late 2024.
Internal documents and workspace content are indexed for SeekAI, which retrieves and synthesizes answers for employees. On the consumer side, LINE and Yahoo! JAPAN user requests are routed through GPT-4-series models, and the resulting summaries or plans are refined with user feedback and LY’s product data.
