Can vectorizer embedding model be changed while in service?

hi @Min !!

You got it right.

You cannot change the vectorizer without vectorizing all your data using the new vectorizer.

Note that the vectorizer is a non mutable configuration of your collection:

So what you’ll need to do is to create a new collection with the configurations you want, and copy your data over so it triggers a new vectorization.

We have a nice example here:

Let me know if that helps!

THanks!
