Stanford's Computer Science Department is launching a new course CS329Z "Engineering AI Agents" in Fall 2026, shifting the focus from monolithic large models to composite systems consisting of retrievers, tools, optimizers, and multiple models.

The course website outlines a path that begins with hand-writing RAG, tool invocation, and agent loops, followed by comparing what has been abstracted away in frameworks like DSPy, LangChain, LangGraph, and LlamaIndex. The syllabus includes tool and function calls, Model Context Protocol, code sandboxing and retries, multi-agent systems, evaluation, and coding agents. Classes will be held on Mondays and Wednesdays from 1:30 PM to 2:50 PM in Packard 101, offering three credits, starting around September 23 for the fall semester. Prerequisites point to NLP backgrounds such as CS224N, CS224V, CS336, or CS221.

Instructors include Diyi Yang, Michael Ryan, and John Yang. The school is also offering a remote class with the same name, costing $4,866, lasting 10 weeks with 9 to 15 hours of work per week, with enrollment open until September 6. Additionally, CS329A "Self-Improving AI Agents" runs concurrently, covering topics such as expansion during testing, validators, feedback loops, and long-term memory. CS329Z emphasizes two application assignments plus a semester project, requiring students to select problems, decompose them, choose components, conduct evaluations, and explain trade-offs.

This course incorporates MCP, multi-agent failure cases, and the principle of "implementing from scratch before introducing frameworks" into the core curriculum, effectively formalizing the industry stack developed over the past two years into Stanford's fall catalog. Diyi Yang has previously taught human-centric LLM courses and participated in language agent tutorials. The school text states that the shift from single models to composite systems represents a fundamental change in application construction methods.

From a market mechanism perspective, this represents a repricing of elite school credits for industry positions. The buyers are students aiming for agent engineering roles and professionals who can afford the nearly $5,000 remote class, while the sellers are the computer science department that has integrated the latest protocols into the syllabus. Funding comes from tuition and online projects, benefiting employers who have already adopted MCP and evaluation as default skills, while putting pressure on departments that still consider the previous generation of courses as core training, and training programs that only teach invocation of encapsulated models without teaching from scratch.
