Simple single-file key-value store database built on SQLite. Lightweight, portable, and designed for embedding in other applications.
About Kohaku Lab
Kohaku Lab is a virtual lab made by enthusiasts who build tools we actually want to use ourselves.
We publish research at top venues (LyCORIS at ICLR 2024, TIPO at ICLR 2026), build infrastructure we rely on daily (KohakuHub, KohakuRiver), create databases and ML utilities, and even play with AI-powered board games. Simple as that - scratch your own itch.
No grand mission. Just people building things they want to exist, sharing them openly, and having fun in the process. Everything we make is 100% open access.
Virtual First
Global collaboration without geographic boundaries
Open Access
Everything we create is freely accessible to all
Research Driven
Pushing boundaries with innovative techniques
Community Focused
