PG Vector Search Stopped Working On Newest Embedding Model

I’ve just done this migration on two databases in Production, (both using pgvector) and the only issue I hit was with the similarity search - the thresholds need to be changed. I had a cosine distance threshold filter set at 0.8 which worked great with gen 2, but with 3rd gen no results were coming up. You have to lower this value to almost half to get results as the 3rd gen is more picky!

No, this was not the problem. The problem was regardless of threshold, the order of cosine distance was prefering data that was clearly more different. And that’s definitely a problem!
