# Delete Vectors

> Deletes the vectors with the given ids.

You can delete one or more vectors by providing their vector ids,
vector id prefix, or metadata filter.

<Tip>
  Vectors will be deleted from the default namespace by default.
  You can use a different namespace by specifying it in the request path.
</Tip>
