Can I use H2O.ai tools on my own infrastructure or is it cloud-only?

H2O provides both. The core platforms (H2O-3, Driverless AI, LLM Studio) can be deployed on-premise or in private clouds. H2O AI Cloud is their fully managed cloud offering.

How does H2O.ai support generative AI use cases?

Through products like h2oGPTe (enterprise GenAI platform), LLM Studio (no-code fine-tuning), and pre-built models like Danube3 (SLMs) and Mississippi (vision-language models).

What are the technical requirements for running H2O-3?

H2O-3 requires a Java Virtual Machine (JVM). It scales across clusters but can run on a single machine. It integrates with R and Python clients and Spark (via Sparkling Water).

Is H2O.ai suitable for building and deploying real-time models?

Yes. Driverless AI supports real-time scoring deployments, and H2O MLOps provides model monitoring and governance for production pipelines.

How does H2O Driverless AI achieve automatic feature engineering?

It uses a combination of rule-based logic, genetic algorithms, and loss function-based algorithms to automatically generate and select high-performing features from raw data.

AI & Machine Learning: The Foundation Behind Every AI Solution

Every agent, language model and predictive system is built on the same foundation. Get this part right and the rest of the glossary is easier. Terms covered: - Artificial Intelligence: systems that learn, adapt and improve from data instead of following fixed rules written by a programmer - Machine Learning: the mechanism, where a model learns to tell fraud from non-fraud by seeing thousands of examples - Features: the variables and attributes that tell a model what to pay attention to - GPU: the hardware that makes training viable on text, images and video, built for thousands of calculations running at once AI sets the vision. Machine learning is the mechanism. Features are what the model learns from. GPUs are what make it scalable. — AI Fundamentals Glossary | H2O.ai University Full playlist: https://www.youtube.com/playlist?list=PLAWKlIKS-66E Free courses and certifications: https://h2o.ai/university #MachineLearning #AI #GPU #AIGlossary #H2Oai

Knowledge Graphs & Ontology: How Agents Understand Enterprise Context

AI does not automatically understand your organization. It does not know how your products relate to your customers or what your internal terminology means. It needs a map. Terms covered: - Knowledge Graph: information represented as a network of connected entities and relationships rather than rows in a table, so an AI system can reason over how things relate - Ontology: the formal framework that defines the concepts in your domain and how they connect, giving the graph its logic In healthcare, an ontology defines what counts as a symptom, a diagnosis and a treatment. In finance, it defines instruments, transactions, counterparties and risk categories. Together they give AI a shared understanding of your world, so it reasons accurately instead of guessing. — AI Fundamentals Glossary | H2O.ai University Full playlist: https://www.youtube.com/playlist?list=PLAWKlIKS-66E Free courses and certifications: https://h2o.ai/university #KnowledgeGraph #Ontology #AI #AIGlossary #H2Oai

MCP & MCP Runner: The Protocol Behind Agent Communication

MCP & MCP Runner: The Protocol Behind Agent Communication

Connecting an agent to a new tool used to mean custom integration work every single time. MCP is the standard that removes that. Terms covered: - MCP (Model Context Protocol): a standardized way for AI models to communicate with external tools and data sources. One standard, many integrations. - MCP Runner: the runtime component that manages those connections and makes sure the interactions happen reliably at scale In practice: a healthcare organization connects an agent to patient records, scheduling and compliance tools through the same protocol. A financial services firm links market data, risk systems and reporting without rebuilding the connection layer each time. MCP defines how agents talk to the world. The MCP Runner makes those conversations happen. — AI Fundamentals Glossary | H2O.ai University Full playlist: https://www.youtube.com/playlist?list=PLAWKlIKS-66E Free courses and certifications: https://h2o.ai/university #MCP #AIAgents #AgenticAI #AIGlossary #H2Oai
