This is the actual vector of your object. So considering you never passed a vector when you created that object, it was generated by your transformers model.

this endpoint http://localhost:8080/v1/objects?include=vector will yield all the objects in your cluster.

So this is a list of objects, and one of the properties is the class it belongs to.

Let me know if this helps :)
