Best for Teams putting NLP into a production service rather than a research notebook. Teaching, learning and prototyping classic NLP techniques rather than production deployment. Discovering latent topics or training custom word embeddings on large text corpora. Teams that want pretrained neural models for text, vision or audio without training from scratch.
