Documents

5 documents, published 5 Apr 2025 to 10 Aug 2026. The chart runs from each document's publication to its latest known version; the table lists them newest first, each linking to its page.

Meta's documents and the versions we know of

One row per document, from its publication to its latest dated version. A tick marks each later version whose date we know, from a changelog, a date in the document or our source registry.

A copy we retrieved without knowing when that version was published has no tick: its only date is the day we read it. The table lists every version, with how its date is known. Versions known only from a changelog have no copy we hold yet.

Frameworks and versions used

A risk determination is a developer's formal decision on whether a model crosses a risk threshold (Methodology §8). They are counted here by the framework and version each one names, as recorded; each model's page shows the levels as printed. Levels are never mapped between frameworks.

6 determinations are recorded from Meta's documents. 1 of them names no framework.

Read this as a lower bound: some documents were not read to the end in version 0 (each document's page says how far), so families reported late in them may be undercounted. Values read off a figure, stated in words, or given as a category do not count.

Changelog practice

A document has a changelog when it keeps its own record of the changes made to it after publication. Where it keeps none, changes can only be found by comparing its versions (Methodology §7).

Of Meta's 5 documents, 1 has a partial changelog and for 4 a changelog does not apply.

How many of Meta's documents keep a changelog.

No restated values are recorded: no later Meta document is recorded as reporting an earlier model's result again.
