One of the central messages from THEMIS 5.0 is that trustworthiness cannot be reduced to technical performance alone. The Policy Brief highlights that concepts such as fairness, accuracy and robustness need to be understood in relation to the particular sector, use case and deployment environment. It also stresses the importance of governance, organisational readiness, user skills, operational practices and ethical and legal oversight.

Researchers and practitioners working on trustworthy AI gathered in Bremen on 15–16 August for TRUST-AI 2026, the Second European Workshop on Trustworthy AI, held as part of IJCAI/ECAI 2026.

Artificial intelligence is rapidly becoming part of everyday clinical practice. Across Europe, AI is now supporting radiologists in detecting lung nodules, identifying breast cancer, assessing stroke patients and prioritising imaging studies. These technologies promise earlier diagnosis, improved efficiency and reduced workload at a time when healthcare systems face increasing demand and workforce shortages. Yet despite remarkable advances in performance, one question continu

Before the creation of LLMs (Large Language Models) that converse in natural language, we humans have had little experience developing trust in complex relationships outside the confines of our own species. So far, we have only established trust with reasoning-subordinate species such as animals domesticated for agriculture and man’s best friend, the dog. Since these animals lack human-like reasoning skills and speech, the dimensions of and expectations associated with trust

As part of the New European Bauhaus Festival, THEMIS 5.0 was proud to be represented at the DIGISET Forum, a satellite event hosted by CollectiveUP and FARI – AI for the Common Good Institute in Brussels. Bringing together experts from across the fields of artificial intelligence, social economy, civic participation and innovation, the forum explored how AI can contribute to more inclusive, sustainable and democratic societies. Representing THEMIS 5.0, Adam Doulgerakis of

As the project enters its final phase, partners are focusing on integrating and validating the various components that make up the THEMIS platform. While each tool provides value on its own, the real strength of THEMIS lies in how these components connect and complement one another in our integrated platform for trustworthy AI.

As artificial intelligence becomes increasingly embedded in public services, ensuring that AI systems are not only efficient, but also trustworthy and accountable, is becoming a key challenge for organisations across Europe. This question was at the heart of the AI-Enabled Public Services: Building Resilience and Accountability webinar, held on 30 April 2026 and co-organised by the European-funded projects THEMIS 5.0, HumAIne, TANGO and AIXPERT.

Professor Mentzas highlighted several emerging risks associated with Agentic AI that existing governance frameworks were not originally designed to address. These include: Goal misalignment between human intentions and AI objectives Cascading failures across multi-agent systems Indirect prompt injection attacks Persistent memory poisoning Unpredictable interactions between autonomous agents As AI systems become more autonomous, these challenges create ne

For years, the conversation around artificial intelligence has revolved around a single, urgent question: can we trust it? In 2026, that question is starting to feel incomplete. A quieter, more complex issue is emerging beneath the surface, one that is far less discussed, and far less regulated. What happens when people trust AI too much?

The TRUST-AI 2025 workshop in Bologna, organised as part of the European Conference on Artificial Intelligence (ECAI) and supported by THEMIS 5.0 and its consortium partners, including SINTEF, University of Piraeus & ICCS, NTUA, University of Southampton, KU Leuven, Centre for IT & IP Law, ATC- Athens Technology Centre, Institute of Philosophy & Technology, and Engineering, offers one of the clearest windows into how researchers and practitioners across Europe are trying to

Europe is having a defining moment with artificial intelligence. Not because it is building the biggest models or attracting the most investment, but because it is trying to answer a harder question: can AI be trusted?

The EU AI Act correctly insists on human oversight. Its intention is clear and necessary: ensure that humans can analyse, intervene, and improve AI-driven decisions. However, this creates a paradox. Placing a human 'in the loop' does not automatically guarantee real judgment, real veto power, and real cognitive engagement. In fact, poorly designed oversight requirements can make organisations more fragile, because they rely on a form of human presence that is nominal rathe

On 28 January 2026, the THEMIS 5.0 project contributed to the online webinar “From Command to Collaboration: Reimagining the Human–AI Relationship”, jointly organised with the EU-funded projects THEMIS 5.0, TANGO, AI4REALNET, HumAInE, PEER AI and COMFORTage. The event brought together more than 50 participants from research, policy, and practice communities across Europe.

Recent UK research on traditional media in the age of AI, by OnePoll for 72point, shows something striking: about 44% of UK adults say they trust artificial intelligence to deliver more truthful and factual information than they trust the government (38%), and social media influencers (24%). While traditional news outlets remain the most trusted at 55%.

Every day, artificial intelligence becomes more woven into our decisions, in hospitals, ports, newsrooms, and beyond. Yet despite the promises of transparency and accountability, one question remains stubbornly open: do we actually trust AI?

Joan Meseguer Llopis from Fundación Valenciaport, recently participated as a speaker in the workshop “Artificial Intelligence from the Social Perspective,” organized by Forética at NTT DATA’s offices in Madrid, as part of the Responsible Artificial Intelligence Forum.

New policy brief AI, Your Way: Trusted, Scalable, and Ready to Deliver, which distills insights from the AI, Data and Robotics Forum (ADRF) 2025 workshop co-organized by five Horizon Europe projects: THEMIS 5.0, TANGO, AI4RealNet, PEER AI, and HumAIne.

As Europe takes a historic step toward regulating artificial intelligence with the adoption of the EU AI Act, a critical question is gaining attention: can we ensure fairness in AI systems without meaningful human oversight?

This week THEMIS project partners gathered in Copenhagen at the Democracy-X offices for a two-day project meeting, an important milestone marking the midway point (18 months) into our mission to create a system that helps professionals assess and improve the trustworthiness of AI.
