GPAI Ledger The public record of EU AI Act training-data summaries

GPAI Ledger › Muse Image (Meta)

Muse Image

Public summary of training content · Article 53(1)(d), Regulation (EU) 2024/1689

Provider: Meta — status: Published

Meta publishes a public summary of training content for Muse Image under the EU AI Act; every version this ledger has captured is archived below with its hash and timestamp proof.

AIAL metadata: summary dated 2026-07-06, model released 2026-07-07, eval page

Latest version differs from the previous one: 3 word(s) of extracted text changed between the captures of 22 Aug 2026 and 28 Aug 2026 (the comparison re-extracted both copies with one tool; the archived extracts on this site need not reproduce this count); both versions are archived below with their full text.

Version difference observed: the newest live copy and the archived third-party copy of this summary currently differ in content (text similarity 0.99). The rows below serve both — compare the extracted text of the two document versions to see the difference.

Document versions

Rows may capture the same summary from different sources or formats (the provider's site, AIAL's archived copy); sizes and hashes are comparable only within one URL.

Watch-surface captures

Captures of the page(s) where the document is published (portals, hubs, docs pages) — monitored for change detection; not the document itself.

Third-party evaluation

The AI Accountability Lab scores published summaries against the Commission's template and publishes the result. These are captures of their assessment, archived here because they are revised over time and a score is otherwise unrecoverable once changed. It is AIAL's research judgement, not a legal determination, and not the provider's document. Their assessment is archived here but not served on this site or in the dataset: each capture below proves what was published and when, and points to AIAL for the content. Attribution: aial.ie.
