Nyckel classification API

Last year, Nyckel announced the launch of our pretrained classifiers. These let anyone launch their own machine learning model in just minutes. Since then we’ve been releasing more every month, and below contains all of our new classifiers this month.

These classifiers exist as public-facing pages that anyone can interact with. We also offer API access to the models for free.
