Karpathy’s Known Two-Hour LLM Lecture Dates to 2025, Not a New Agent Course

A widely shared description presents a two-hour Andrej Karpathy lecture on agents, harnesses, loops and graphs as a new release. The documented two-hour video on his channel is “How I use LLMs,” published on February 27, 2025, and its chapters cover practical LLM use rather than that agent-engineering syllabus.
