#### CNN/CPU pipelines with floret vectors
The Finnish, Korean and Swedish `md` and `lg` pipelines use
[floret vectors](/usage/v3-2#vectors) instead of default vectors. If you're
running a trained pipeline on texts and working with [`Doc`](/api/doc) objects,
you shouldn't notice any difference with floret vectors. With floret vectors no
tokens are out-of-vocabulary, so [`Token.is_oov`](/api/token#attributes) will

differences because floret vectors don't include a fixed word list like the

In the transformer (`trf`) pipelines, the `tagger`, `parser` and `ner` (if
present) all listen to the `transformer` component. The `attribute_ruler` and
`lemmatizer` have the same configuration as in the CNN models.
For spaCy v3.0-v3.6, `trf` pipelines use
[`spacy-transformers`](https://github.com/explosion/spacy-transformers) and the
transformer output in `doc._.trf_data` is a
[`TransformerData`](/api/transformer#transformerdata) object.
For spaCy v3.7+, `trf` pipelines use
[`spacy-curated-transformers`](https://github.com/explosion/spacy-curated-transformers)
and `doc._.trf_data` is a
[`DocTransformerOutput`](/api/curatedtransformer#doctransformeroutput) object.
