About — systemcards.org

systemcards.org is a public index of AI model documentation: model cards, system cards, and independent evaluation reports.

Catalogs documents from an allowlist of AI labs and independent evaluators.
Links the original of every document, and keeps an archived copy of every version it has captured, downloadable from each document's version history.
Fingerprints every document daily. Silent edits become recorded versions.
Shows provenance for every entry: when, how, and why it was added.

A deterministic monitor checks every link daily, re-fetches a rotating subset, and diffs publisher index pages for new documents.
An LLM agent triages candidates and proposes entries. A deterministic validator (allowlist, fetchability, dedup, caps) has the final say on every write.
The database is public SQLite in the GitHub repo; this site is a static export of it.

Every captured version is archived byte for byte and named by its SHA-256, so anyone can verify a copy. Edits and removals stay checkable after the publisher changes the page.
Download everything: the dataset (database, extracted text, manifest), the manifest of every version with its hash and link, and wget -i https://data.systemcards.org/urls.txt for all originals.
Archived copies are of publicly released documents; rights remain with their publishers. To request removal of a copy, write to [email protected].
