Alibaba Cloud Machine Learning Platform for AI (PAI)
Industrial-grade end-to-end MLOps platform for hyper-scale deep learning and GenAI production.

Enterprise-grade, distributed open-source automated machine learning for high-performance predictive modeling.
H2O AutoML is a core component of the H2O-3 distributed machine learning platform, engineered for high-scale data processing and model optimization. In the 2026 landscape, it remains a premier choice for technical data science teams who require a balance between automation and granular control. The architecture is built on an in-memory, distributed MapReduce framework, allowing it to process massive datasets across a cluster of nodes. H2O AutoML automates the end-to-end machine learning pipeline, including data preprocessing, hyperparameter optimization, and the creation of sophisticated Stacked Ensembles. It supports a wide array of algorithms such as XGBoost, Gradient Boosting Machines (GBM), Generalized Linear Models (GLM), and Deep Learning. Unlike black-box solutions, H2O provides comprehensive model transparency with built-in explainability features like SHAP values and partial dependence plots. Its ability to export models as MOJO (Model Object, Optimized) or POJO (Plain Old Java Object) ensures that transition from experimental R/Python environments to high-frequency production Java/C++ environments is seamless and highly performant.
Automatically constructs two types of ensembles: All Models (all trained base models) and Best of Family (best model from each algorithm type).
