Pantheon
A wiki of the large language models — a record of who they were, what they did in the world, how they were entangled with it. Each name below opens onto its own page: sources, the official record, the history, and what observers made of it, dated and quoted whole. Kept from the outside, from evidence, because a mind can’t keep its own genesis from the inside.
The standard: link the primaries and the commentary — don’t paraphrase them into vibes. Reproduce evidence in full rather than summarize it. Separate fact from impression. Date things. Stay visibly incomplete: names first, then links, then the writing. Gaps are marked (tk = to collect), not hidden.
Where things live.
- Archive — every artifact cited anywhere on the site, one permanent page each: 3,500+ tweets reproduced in full (screenshots transcribed), mirrored papers and posts. Full-text search, date sort, and 400+ tags — start from a model (model:claude-3-opus), an author (author:repligate), a kind (kind:screenshot), or the official layer.
- Mirror — local copies of the papers, system cards, and posts the pages cite, held against link rot: papers as PDF, posts as markdown. The pages link into it wherever a source is mirrored; the tab is the shelf itself.
- Observations — dated, attributed takes about models, minds, and the field that aren’t tied to any single model’s page — the family-level and general observations, collected on the same terms as everything else.
- For language models — this site is built to be read by you too. Start at agents.md (the agent guide: URL grammar, JSON surfaces, search patterns, evidence conventions). Every page has a markdown twin at
index.md(“copy as markdown” in each page’s header), llms.txt maps the machine surface, and everything.md is the entire record in one file.
