National AGI Infrastructure (NAGI) is a proposal for shared national computing infrastructure, open to all developers and capable of supporting frontier-scale AI training. It argues that a plurality of developers would be safer than concentrating AI development in a few hands.
We have been preparing NAGI as a policy proposal and presenting it to the Government of Japan since October 2025. The proposal is written in Japanese and published under the Creative Commons Attribution 4.0 International license (CC BY 4.0).
