The public record of EU AI Act training-data summaries

Article 53(1)(d) of the EU AI Act requires every provider of a general-purpose AI model placed on the EU market — open-source models included — to publish a public summary of training content. Providers publish these documents on their own sites and can change, move, or remove them at any time — no official registry exists. The GPAI Ledger checks every known summary on a daily schedule and archives every version with a SHA-256 hash, an OpenTimestamps proof, and — where the URL permits — a Wayback snapshot, so what was published, and when, stays provable. What is a training-data summary?

Status legend — published: a summary document is located and captured. missing: no summary located — for AIAL-tracked models this reflects AIAL's research assessment that one is required (not a legal determination); for models added by this project's own monitoring, obligation has not been assessed. regulatory: official Commission documents, archived for reference. watch: pages we monitor because summaries or template changes may appear there first. Documents counts distinct document versions (byte- or text-identical copies, such as the provider's file and AIAL's archived copy, count once); Captures counts all stored snapshots including monitoring pages.
