Lance Martin of Langchain will discuss the shift in AI from model training to orchestrating powerful LLMs and computing primitives via a new software discipline. Discover practical context engineering techniques—including managing context rot, reduction, offloading, and isolation—and building effective agent harnesses for managing tool calls in non-deterministic systems. This session emphasizes that simplicity and observability remain vital, requiring builders to continuously rearchitect due to exponentially improving foundation models.
