Today in Compute College

Lesson & Term of the Day

Today's lesson

Evaluate agents and multi-step workflows

Evaluate the complete path of an agent or workflow, including tools, retries, stopping, and final outcomes. Why it matters today: Today's lesson connects the AI Engineering track to the compute market readers are watching.

Term of the Day

Prompt injection

Prompt injection is an attempt to make a model follow instructions hidden in material it was meant to read. The material might be a web page, document, or tool result. A retrieved page tells an assistant to ignore the user and reveal private information. That page is evidence to read, not permission to act.
