Ultra efficient vector extension for SQLite
Making vector search fast, memory-efficient, and natural in SQLite.
These projects are valuable experiments, but they didn’t solve the constraints we were facing: speed, memory limits, and natural SQL usage. With quantization + preload, queries run in under 4 ms, roughly 17× faster than sqlite-vec, while still achieving perfect recall. Vector search is becoming an essential feature in many modern applications; yet, the SQLite ecosystem lacks an extension that meets the everyday needs of its community.
