Karpathy says he no longer reads or writes code
Andrej Karpathy, who joined Anthropic in May, described building a video site from Hacker News recommendations in about two hours by talking to Claude, and said his own work was a cloud key, a server and a domain. In later posts he described the engineering stack moving from the model to the graph.

Karpathy’s HackerTube collects 6,454 videos from 2007 to 2026, chosen from 40,000 Hacker News comments that the model downloaded, filtered and kept. He wrote that he now only talks to the model and does not read code or run terminal commands. The time and the division of labour are his own account, and he works for the company that sells the model.
In separate posts he framed engineering as moving from the model to the prompt, the agent, the loop and the graph, and argued that an observer in the 1970s could have reasoned from digital knowledge work, the internet and big data to something like today’s language models.
