Public summary of training content · Article 53(1)(d), Regulation (EU) 2024/1689
Provider: Microsoft — status: Published
Microsoft published a public summary of training content for MAI-Image-2 under the EU AI Act. The copy this ledger tracked no longer resolves (see below); every version captured while it did is archived here with its hash and timestamp proof.
AIAL metadata: summary dated 2026-03-19, model released 2026-03-19, eval page
The provider's copy of this document no longer resolves. Confirmed on 28 Aug 2026 — checked from a second, unrelated network as well as this project's daily runner. The archived version(s) below, with their SHA-256 hashes and OpenTimestamps proofs, are unaffected; the address that stopped answering is https://microsoft.ai/pdf/MAI-Image-2-Data-Summary.pdf.
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.

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.
