Best for	Discovering latent topics or training custom word embeddings on large text corpora.	Teams putting NLP into a production service rather than a research notebook.	Teaching, learning and prototyping classic NLP techniques rather than production deployment.	Teams that want pretrained neural models for text, vision or audio without training from scratch.
Pricing	Free and open source with no paid tier. Pricing has not been verified yet — see the vendor's site.	Free and open source; Explosion AI separately sells the Prodigy annotation tool, but spaCy itself has no paid tier. Pricing has not been verified yet — see the vendor's site.
