NTT has announced an update to its LLM (Limited Licensing Memory) system, “tsuzumi2.” Due to its lightweight design, tsuzumi2 is increasingly being used in on-premise and private cloud environments to handle sensitive information. This update focuses on the fact that documents containing sensitive information often include charts and diagrams. It was developed to understand the visual meaning of documents containing charts and diagrams by reading them as images. In addition to chart and diagram understanding, it also enhances logical thinking capabilities such as numerical processing, which are essential for practical use. By prioritizing the understanding of Japanese business documents, it achieves world-class performance compared to models of the same size.
