# sqlite-vector

A SQLite extension for working with float and binary vectors.

Still a work in progress, not meant to be wildly shared!

Once complete, you'll be able to do things like:

```sql

.load vector0

-- create a "vector" object from json

select vector_from_json(

  json('[0.1, 0.2, 0.3]')

);

-- convert a vector object into a compact BLOB

select vector_to_blob(

  vector_from_json(json('[0.1, 0.2, 0.3]'))

);

-- Result: X'760103000000cdcccc3dcdcc4c3e9a99993e'

select vector_length(

  vector_from_blob(X'760103000000cdcccc3dcdcc4c3e9a99993e')

);

-- Result: 3

select vector_value_at(

  vector_from_blob(X'760103000000cdcccc3dcdcc4c3e9a99993e'),

  2

);

-- Result: 0.3

select *

from vector_fvecs_each(readfile('sift1m_base.fvecs'));
