LLMs for Agent Builders: Context Engineering | Stanford CS329Z Lecture 2 with Michael Ryan
Browse Stanford's online courses in Agentic AI: https://stanford.io/4AIRb2zLecture Overview:
What do you need to know about how LLMs work to build better AI agents? In this Stanford CS329Z: Engineering AI Agents lecture, Stanford PhD student and DSPy contributor Michael Ryan covers decoding strategies (sampling and temperature), transformer attention (including linear and hybrid attention) and context length, the pretraining-to-post-training pipeline (SFT, RLHF, RLVR), inference (prefill vs. decode and the KV cache) and test-time scaling, structured I/O and constrained decoding, and context engineering, including why stuffing everything into the context window backfires.
Speaker: Michael Ryan
Michael Ryan is a CS PhD student at Stanford University developing human-centered, open-source AI systems that augment human intelligence and reflect the plurality of human values. His contributions to the DSPy open-source project enable developers to optimize multi-stage AI systems, and his algorithms are used for automatic AI prompt optimization at Meta, Google, Dropbox, Amazon, and other organizations.
