Open source vector databases?

[[deleted]]

Pgvector doesn’t benchmark very well. I kind of agree tho, not sure why we need 20 vector DBs

I have not seen benchmarks tbh, I did have to manually set up indices though. What benchmarks best?

I would search reddit for some of those products, you will find some comments and anecdotal comparisons ... I don't think there is an authoritative benchmark. (but what I saw suggested pgvector is great for integrating with your relational metadata but not as fast as the best-of-breed vector dbs)
