Source details and check notes Authors Jimmy Ba Version Dated post, retrieved on 2026-10-15 (SHA-256 f8f2acea6323476a08f23c79598dc5a70a3ccec730252add86c374ac303cccea) through X’s own syndication endpoint for the post’s text, which truncates long notes. Canonical address Open the canonical source ↗ Accessed 2026-10-15 Language English (en) Attribution Jimmy Ba, “Post of 11 February 2026 (UTC) on his last day at xAI (X)”, 2026-02-11. 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 (research/lab-genealogy). The paraphrase’s verbatim anchor “helped cofound” matched the retrieved text on 2026-10-15 and again in a fresh retrieval the same day. 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. A cross-family machine check (2026-10-16/17) re-read the record’s sources and agreed with the record. No human editorial review. Status and meaning Editorial status. Not reviewed by an editor . An exploratory record that no editor has accepted. This status does not say whether a person has read any linked passage. Each evidence record above shows how it was checked.
Relation. Participation in founding an organisation or research team. Neither sole founding nor legal incorporation is implied.
Date. Retrospective first-person statement; no founding date is given. See the July 2023 launch roster.
