sqlite-vec an SQLite extension for vector search under development.
"I'm working on a new SQLite extension! It's called sqlite-vec, an extension for vector search, written purely in C. It's meant to replace sqlite-vss, another vector search SQLite extension I released in February 2023, which has a number of problems. I believe the approach I'm taking with sqlite-vec solves a number of problem it's predecessor has, will have a much nicer and performant SQL API, and is a better fit for all applications who want an embed vector search solution!"
"sqlite-vec will be a SQLite extension written purely in C with no dependencies. It will provide custom SQL functions and virtual tables for fast vector search, as well as other tools and utilities for working with vectors (quantization, JSON/BLOB/numpy conversions, vector arithmetic, etc.)."
