Developed by the Luxembourg Institute of Science and Technology (LIST) and the University of Luxembourg\u2019s Interdisciplinary Centre for Security, Reliability and Trust (SnT), the tool lets any organisation build a customised environment for testing if an artificial intelligence system is trustworthy and compliant. This tool lays the groundwork for a shared European infrastructure for AI assessment.<\/strong><\/p>\n\n\n\n<p>Artificial intelligence adoption is accelerating across Europe\u2019s economy and society, and with it the urgency of ensuring that AI systems can be trusted. Organisations cannot unlock the full value of AI unless people trust it: if users doubt every output, or avoid AI altogether, the expected gains never materialise. The EU AI Act and other regulations also impose clear obligations on AI providers to demonstrate trustworthiness. Meeting those obligations today is slow, costly and largely manual. The AI Assessment Sandbox Configurator aims to remove such bottlenecks and enable rigorous AI testing at scale for the growing number of AI agents that are being deployed by organisations.<\/p>\n\n\n\n<h2 class=\"has-text-align-left wp-block-unilux-blocks-heading\"        id=\"customised-ai-testing-environments-for-public-and-private-organisations\"\n    >\nCustomised AI testing environments for public and private organisations<\/h2>\n\n\n\n<p>Ensuring an AI tool is trustworthy and compliant with regulatory requirements involves converting policy requirements into controls and metrics, identifying the relevant tests available, integrating them, reporting test results and preparing for audits. All of this remains a painstaking, largely manual process. The AI Assessment Sandbox Configurator is open source, allowing any public or private organisation to accelerate the creation of customised AI testing environments that can be deployed anywhere \u2014 on premises, on private or sovereign clouds \u2014 making it suitable for organisations with strict data residency or security requirements, for example financial firms.<\/p>\n\n\n\n<p>With the AI Assessment Sandbox Configurator, users gain access to a curated and extensible catalogue of AI tests, controls and datasets, from which they can select those relevant to the specific requirements of their use case. The tool then generates a customised testing environment including a collaborative dashboard to visualise and assess the results, a report generator and temper-proof evidence for auditing.<\/p>\n\n\n\n<p>It is aimed at any organisation \u2014 large enterprises, public institutions, start-ups and SMEs \u2014 that wants to deploy AI responsibly in cooperation with Competent Authorities and notified bodies.<\/p>\n\n\n\n<h2 class=\"has-text-align-left wp-block-unilux-blocks-heading\"        id=\"built-on-years-of-hands-on-ai-testing-experience\"\n    >\nBuilt on years of hands-on AI testing experience<\/h2>\n\n\n\n<p>The Configurator is a natural next step in SnT\u2019s and LIST\u2019s work on AI assessment.<\/p>\n\n\n\n<p>For the University of Luxembourg\u2019s SnT, the Configurator builds on almost a decade of extensive research partnerships across industry and the public sector. These partnerships have resulted in research papers published in scientific journals and conferences for AI that are in the top ten percent globally. Since a partnership with BGL BNP Paribas that began in 2017, SnT has also worked with Spuerkeess, the Luxembourg Ministry of Digitalisation, and more recently the European Stability Mechanism (ESM). The research team is also currently collaborating with the National Bank of Greece on a Horizon Europe project, to assess selected AI systems. This industry perspective informed the creation of the AI Sandbox tool.<\/p>\n\n\n\n<p>Maxime Cordy, Assistant professor in Software Engineering for AI Systems and SnT\u2019s project lead, said:<\/p>\n\n\n\n<p><em>\u201cIn our work with partners we experienced first-hand the challenge to integrate cutting-edge technology <\/em><em>into business-critical operations<\/em><em>. This enabled us to produce breakthrough scientific research and in doing so we realised we could use our expertise to contribute an open-source tool to ease AI adoption. AI adoption requires both speed and control, and the AI Assessment Sandbox Configurator enables organisations to integrate AI in their processes in a trustworthy manner, supporting them in their global competitiveness.\u201d<\/em><\/p>\n\n\n\n<p>For several years, LIST has operated its own <a href=\"https:\/\/ai-sandbox.list.lu\/\">AI Sandbox,<\/a> a hands-on testing environment where organisations evaluate AI models for robustness, fairness, bias and regulatory compliance. That Sandbox has been put to work with organisations including Banque Internationale \u00e0 Luxembourg, the City of Luxembourg, and Mistral AI.<\/p>\n\n\n\n<p>Francesco Ferrero, Leader of the Flagship Initiative on Artificial Intelligence and Head of the Human-Centred AI, Data and Software Research Unit at LIST, said:<\/p>\n\n\n\n<p><em>\u201cWith the LIST AI Sandbox, we showed that rigorous, independent AI testing is achievable in practice. The Configurator is the logical next step: it packages that expertise into an open tool so that any organisation, anywhere, can stand up its own assessment environment without starting from scratch.\u201d<\/em><\/p>\n\n\n\n<p><strong>Made in Luxembourg, built for Europe\u2019s sovereignty<\/strong><\/p>\n\n\n\n<p>Luxembourg AI Factory sees the Configurator as the foundation of something bigger: a shared European resource, co-developed by regulators, researchers, certification bodies, and companies across Member States. The tool also positions Luxembourg as a hub for international companies, particularly in sectors such as finance that wish to deploy AI systems in Europe and need a trusted, sovereign environment in which to assess them.<\/p>\n\n\n\n<p>Over time, the library of tests and controls is expected to expand into specialised offerings for industries such as healthcare, finance, manufacturing and others. Several pilots are already underway across Europe, and the underlying research has been published in several peer-reviewed scientific papers.<\/p>\n\n\n\n<p>Stefano Pozzi Mucelli, Head of Ecosystem Innovation Projects at Luxinnovation, concluded:<\/p>\n\n\n\n<p><em>&#8220;AI adoption only delivers value when AI systems can be trusted. The AI Assessment Sandbox Configurator is a natural extension of Luxembourg AI Factory\u2019s service catalogue: while our services already guide companies from assessment through to deployment, this tool enables any organisation to map regulatory requirements to concrete assessment metrics and generate audit-ready reports on its own infrastructure. It allows us to better serve companies of all sizes, from SMEs to large enterprises, by making trustworthiness practical rather than theoretical. This is how Luxembourg is positioning itself at the forefront of AI in Europe: by treating trust not as a barrier, but as the enabler that helps AI innovation reach the market and its users.&#8221;<\/em><\/p>\n\n\n\n<p>The tool is available on Luxembourg <a href=\"https:\/\/aifactory.lu\/build-and-test\/testing-the-solution\/ai-sandbox-configurator\" target=\"_blank\" rel=\"noreferrer noopener\">AI Factory\u2019s website <\/a>and on <a href=\"https:\/\/github.com\/lux-ai-factory\/aisc\" target=\"_blank\" rel=\"noreferrer noopener\">GitHub<\/a>.<\/p>\n<\/div><\/section>\n","protected":false},"excerpt":{"rendered":"<p>Luxembourg AI Factory released an open-source tool, the AI Assessment Sandbox Configurator, on 10 June 2026.
