Nyckel

Train a custom image or text classifier from a handful of samples on an always-free tier

Nyckel is an AutoML classification and search API: you create a function, upload as few as a few labeled samples per class (image, text or tabular), and it trains and deploys a model in seconds. It also offers image similarity/semantic search and a set of pretrained detectors. Models invoke over a simple REST endpoint.

Free tier

Always-free tier for getting started, no data lock-in; pay-as-you-go and enterprise plans for higher volume

Rate limits
