Since May 2023, the National Institute of Informatics has launched the LLM Study Group (LLM-jp) https://llm-jp.nii.ac.jp/, advancing the construction of open large language models (LLMs) strong in Japanese language and related research and development. In October 2023, it released 13 billion parameter LLMs, and work is currently underway on a 175 billion parameter LLM.

Building on such achievements, the National Institute of Informatics has become the implementing body for the Ministry of Education, Culture, Sports, Science and Technology's project "Formation of a Research and Development Hub for Ensuring Transparency and Reliability of Generative AI Models." Supported by the FY 2023 supplementary budget, sufficient computational resources will be secured, and the Institute plans to actively continue LLM research and development. (For the FY 2024 budget request, see p.6 at https://www.mext.go.jp/content/20230828-mxt_kouhou02-000031628_10.pdf).
