Attribution: Andrej Karpathy, “Andrej Karpathy post on X, 19 May 2026”, 2026-05-19.
Reuse: No open redistribution licence asserted. Bibliographic metadata, editorial paraphrases and short attributed quotations (at most 50 words each). Recheck terms before wider redistribution.
Check notes: Candidate pack passage, lab genealogy 2 (research/lab-genealogy-2). The paraphrase’s verbatim anchor “I've joined Anthropic” matched the retrieved text on 2026-10-29 and again in a fresh retrieval. Read through X’s own syndication endpoint for the post’s text, which truncates long notes. Matching ignored differences of whitespace, case, quotation marks, apostrophes, dashes and Unicode compatibility forms, so the source’s typography can differ. The paraphrase is Selekoa’s; only the anchor is the source’s wording. No human editorial review.
