Safety Card Ledger

Overview

Documents

The system cards, model cards, reports and posts our values come from, with the versions of each that we know about.

Data as of 26 Sep 2026 · Dataset v0.1 · Methodology v0.1 · Changelog

The documents at a glance

The dataset draws on 70 documents from 8 developers: 31 system cards, 22 model cards, 5 technical reports, 4 system card addenda, 3 launch posts, 2 Frontier Safety Framework reports, 2 safety reports and 1 policy post.

15 keep a changelog and 4 a partial one; 20 have none, and for the other 31 we have not established it or it does not apply.

24 have more than one version on record, but we hold copies of two versions for only two of them; the other earlier versions are known only by their date, from a changelog or our source registry.

“With a changelog” counts documents that keep a record of their own changes, fully or in part. “With recorded revisions” counts documents where we have recorded what changed between two versions, each change listed in the revisions ledger.

Versions we hold, and versions we only know of

A document can change after it is published. We record every version we know of, 126 in all, but we hold a copy of only some of them. Only where we hold two copies can we compare them value by value.

Copy retrieved70 versions
We downloaded this version ourselves and read it. Our values come from this copy unless they are marked otherwise.
Earlier copy read2 versions
An earlier version we read in a copy hosted somewhere other than the developer's site, after the developer replaced it.
Known from the changelog; no copy held31 versions
The document's own changelog lists a change on this date, but we have no copy of the document as it was then.
Known to exist; no copy held23 versions
A date we know from our source registry, such as the first publication of a document that was later revised, with no copy held.

No version has a file hash or an archived snapshot of our own yet. From dataset v0.2 each retrieved version carries both (Methodology §7).

All documents

By developer, newest first. A document's page lists its versions, every value recorded from it and any revisions.
