Description
Welcome to CIS-1990! In this course, you will learn how to practically instantiate and apply LLMs by designing intelligent, interactive agents. Moving beyond basic prompting, this course explores the full lifecycle of building LLM-powered applications, from reasoning and planning to extending capabilities with memory, retrieval, and tool integration. Through hands-on projects, you will learn techniques such as Retrieval-Augmented Generation (RAG) and multi-step agent design, while also addressing reliability and safety by diagnosing failure modes, implementing guardrails, and conducting systematic evaluations. The course culminates in a final project where you build and present your own LLM agent. Python proficiency is required, but no prior machine learning background is assumed.

Assignments & Grading
Assignments are due at 11:59 PM Eastern Time. Every student has 3 late days that may be used at their discretion across the semester; beyond this allowance, late work will not be accepted. Grades will be 35% homeworks, 45% final project, and 20% participation. Participation is based on attendance + contribution during class activities. You are allowed to miss class 2 times without penalty (otherwise you need to email me).
