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
