Nyckel is an AutoML-as-a-service platform exposing trained classification models through a REST API (versioned at /v0.9/). Under the hood it benchmarks hundreds of ML models against your training data and selects the best performer, supporting multi-class classification across image, text, and tabular (structured) data types. Inference is served from Nyckel-managed GPU infrastructure with millisecond response times and built-in monitoring for model drift and retraining triggers. The platform is SOC2 certified and HIPAA compliant, with strict data isolation — customer data and models are never shared across tenants.
