Over the last couple of weeks, we've been completely changing the vectorization library in Magic to use sqlite-vector. This library is significantly better than the one we used, implying much less memory consumption, faster, better cohesion (although not perfect).
In addition we've changed the distance calculation to cosine as we retrieve context (RAG process), which should provide better matches. In addition we've got Slack integration (check out plugins), and lots of other goodies for you.
