Lesson & Term of the Day

Today's lesson

What is an AI Cluster?

An AI cluster is a connected system that turns many GPUs and supporting infrastructure into usable model-training or serving capacity. Why it matters today: Today's lesson connects the Power & Data Centers track to the compute market readers are watching.

Term of the Day

Model Context Protocol

Model Context Protocol, or MCP, is a shared way for AI applications to connect to tools and data sources. It standardizes the connection; it does not decide which actions a user has authorized. An application can use an MCP connection to read a project tracker instead of building a different custom connector for every client.
