Andrej Karpathy used a short X post on 2026-02-12 to point people to a cleaned-up, one-page mirror of earlier material hosted at karpathy.ai/microgpt.html. The tweet does not introduce a new argument or tutorial on its own; its main function is to redirect readers to a consolidated page because he wanted the content in a single place instead of a gist. The linked page is mostly a personal hub summarizing his current work at Eureka Labs, his recent OpenAI work on midtraining and synthetic data, his Tesla and Stanford history, and a large archive of talks, teaching resources, projects such as micrograd and char-rnn, and publications. Because the post is essentially a link-share and mirror announcement rather than standalone analysis, its value is primarily as a bookmark to Karpathy’s consolidated materials.
