Select a model and receive an alert when its assessment changes. No noise — only meaningful changes: a property crossing from PASS to FAIL, a significant score movement, or a major regression detected.

About This Report
What the Hastings Report is and is not
The Hastings Report is a public assessment of major AI models against EU AI Act formal standards. It is a market intelligence product, not a compliance determination. It demonstrates the Modulith methodology on publicly available models so that buyers, governance teams, and reviewers can see what a standardized assessment looks like.
The Hastings Report is not a Modulith Lab Cert. A Lab Cert is a formal assessment artifact for a specific customer's implementation, with a report ID, evidence appendix, and operational note. The Hastings Report demonstrates the methodology. The Lab Cert applies it to your implementation.
The report is named after Hastings, England, where Modulith Research CIC is based.
