The Lucie-7B LLM and the Lucie training dataset: lessons learnt from training a true open source AI model

We will present both the Lucie Training Dataset and the Lucie-7B models, resources created by the OpenLLM-France community. The Lucie Training Dataset is a multilingual collection of textual corpora designed to offset anglo-centric biases in many LLM training datasets. It contains documents in French, English, Spanish, German and Italian, with French contributing the largest share. It also includes some code. The Lucie-7B models include the foundation model, Lucie-7B, and two instruction fine-tuned versions of this model, Lucie-7B-Instruct-v1.1 and Lucie-7B-Instruct-humandata. Lucie-7B is trained on equal amounts of data in French and English in an effort to better represent cultural aspects of French-speaking communities. The instruction models are intended asdemonstrations of the foundation model in use and figure in a larger effort to release aligned models in the near future. The Lucie resources are all open which makes it one of the first LLM compliant with the OSI definition. The datasets figuring in the Lucie Training Dataset are described and almost all datasets are redistributed in the form used for training on Hugging Face. Model weights for Lucie-7B and the Lucie instruct models, along with intermediate checkpoints for the former, are likewise published on Hugging Face under Apache 2 license, while model training and data preparation code is freely available on GitHub under AGPL v3.

Scaling Trustworthy and Responsible Machine Learning with Khiops: Automated, Interpretable, and Open Source

Unlike many AutoML solutions that focus solely on model selection and hyperparameter tuning, Khiops automates the entire pipeline, including feature engineering, variable selection, and model building, while ensuring results are interpretable and robust against overfitting—all without hyperparameter tuning. Khiops is particularly powerful for multi-table datasets, a common scenario in real-world applications such as fraud detection, risk assessment, and predictive maintenance. It natively processes relational data structures (e.g., customer transactions, logs, IoT data) and extracts the most relevant predictive patterns automatically, without requiring manual data transformations. By combining efficiency, interpretability, and ease of deployment, Khiops is an ideal solution for organizations looking to scale AI responsibly and effectively.

Small seeds – why funding new ideas matters

How do we fund technology in a sustainable way? While financing infrastructure and its maintenance is extremely important (no questions asked), in this talk we want to explore why a diverse funding landscape that also allows for supporting people and groups with new ideas, that have been under the radar before, can only be incredibly valuable to the field of open source. How can we use existing funding structures, bend and twist them to meet the real needs of communities? How can we make them more useful to projects and people who are not typically the recipients of their money? We want to talk about how to build support infrastructure that allows us to fund in ways that bring more diversity, more joy in experimenting, more novel ideas and more inclusivity to our communities - and we want to talk about how to do this in a sustainable way. With the Prototype Fund we have funded almost 400 projects by and for the civil society in the past eight years. This has taught us a thing or two about the different wants and needs of grantees, about what they value in funders and the importance of flexibility when funding inividuals and their innovative ideas. This talk is a call to government institutions, funders and other organisations with the power to distribute money to join forces, break down the barriers that might come with their traditional funding models and create a vibrant network of small, diverse and lightweight funds that meet the needs of different communities. It is an invitation to communities to come together and share their needs in order to help build structures that can actually support their work.

OCS Inventory: A key component of ITSM for complete IT asset control

OCS Inventory enables the collection and centralization of all information from the IT infrastructure by gathering detailed data on hardware (hardware configuration, components, peripherals) and installed software (versions, licenses, updates). It provides a comprehensive view of IT assets, essential for optimizing security, ensuring compliance, and enabling proactive IT management. Thanks to its API, integration with ITSM solutions is simplified, enabling advanced data utilization. We will explore several use cases, including proactive management through notifications, compliance enforcement by detecting configuration discrepancies, and cybersecurity through software version and patch control. This proactive data utilization can be enhanced by mechanisms such as: • Detecting configuration discrepancies (identifying deviations from reference configurations). • Automating alerts for anomalies in the infrastructure (outdated software, detected vulnerabilities). • Integration with security tools for equipment security and compliance. We will discuss several use cases, including network equipment discovery via SNMP, proactive data exploitation through alerting rules and behavioral analysis, compliance and cybersecurity with software version and patch control, and automating ITSM processes through integration with IT workflows.

France Numérique Libre: how local authority IT managers launched a national initiative.

France Numérique Libre was born in April 2025 when local authority IT managers decided to get together and exchange information on free software solutions and services. Firmly rooted in the French opensource eco-system, it is supported by national associations and the French government, which is offering more and more open-source solutions to local authorities. Open to the world and to new developments in the field, France Numérique Libre aims to accelerate the opensource dynamic in France, which is definitively gaining momentum. France Numérique Libre is a demonstrator: by drawing on existing open-source resources, French local authorities can self-organize and create, without any associated budget or major effort, a network of players serving the residents and agents who serve them. By positioning itself as a new player, integrated from the outset into an already rich ecosystem, France Numérique Libre nourishes the hope of leading to new initiatives, potential opportunities for mutualization... and fruitful collaborations between local authorities and with economic partners.

Building digital commons with the public: it starts by reusing their projects

In the pursuit of fostering digital commons, collaboration with the public sector is essential. By reusing and contributing to open-source projects initiated by public administrations, we can create a robust ecosystem that benefits both the public and private sectors. This talk will explore how reusing public projects can lead to shared governance and a thriving open-source software (OSS) ecosystem. Key Points: **Decidim Case Study:** Decidim is an open-source platform designed for participatory democracy, enabling citizens to engage in decision-making processes. The project is a result of public investment from the city of Barcelona. It is now a vibrant open source ecosystems with more than 10 integrators, 150 contributors and instances running all around the Globe. **The sovereign workspace opportunity 🇪🇺 for the FLOSS ecosystem** With La Suite Numérique and OpenDesk we have the opportunity to create a credible alternative to internet giants' solutions at a moment in history where it is the crucial. If states cities and open source companies work together we'll get there faster and sooner. **From Reusing to Contributing to Shared Governance:** Often we see public entities adopting open source software, most of the time relationship with software editors go great but sometimes it gets harder. The path to true sovereignty is the one that leads to autonomy meaning, operating their infrastructure, contributing to the code and have a say on the roadmap. For large organization as budgets margins becomes thinner the licence models becomes less financially viable and slows down adoption of open source solutions. So what if we do it the other way around, public organization as editors, and businesses as reusers and contributors. We'll discuss the potential benefits of this approach. Conclusion: By reusing and contributing to public open-source projects, we can build a strong foundation for digital commons that benefits everyone. This talk aims to inspire attendees to engage with public sector initiatives and contribute to a shared vision of open, collaborative governance.

Generating SBOMs from binary applications

This talk will describe my work in extracting relevant information from an ELF binary in order to create a SBOM from an application within a deployed environment. It can identify features such as the dynamic libraries and the functions used within each dynamic library. It will also show that once the information has been extracted it can be combined with data produced by SBOM generators for deployed applications such as distro2sbom to create a more enriched SBOM. With regulations such as the EU Cyber Resilience Act (CRA) requiring applications to monitor and remediate, as necessary, vulnerabilities in the constituent components of an application, it is essential that an accurate inventory of the components within an application can be identified. Some of this work has been funded through the NGI0 Core Fund, a fund established by NLnet with financial support from the European Commission's Next Generation Internet programme, under the aegis of DG Communications Networks, Content and Technology under grant agreement No 101092990.

Le débat: sovereignty and OSS in Europe

Open source is a driver of innovation and a strategic lever for digital sovereignty, enabling technological independence and transparency through concrete initiatives and collaborative models. The debate highlights the importance of framing open source commons with ethical rules, appropriate licences and data governance, in conjunction with EU regulatory requirements. Despite the recognized benefits, there are still obstacles to community sharing, which need to be overcome through incentives and the structuring of best practices to pool efforts and ensure the long-term viability of projects. Cooperation between players, standardisation and interoperability are essential to strengthen the resilience of the ecosystem in the face of external dependencies and proprietary lock-in. Lastly, building awareness of open source and promoting collective contributions are essential to ensure the sustainability of initiatives and the development of skills among all stakeholders. Does open source guarantee sovereignty and technology independence? What role can it play? We will discuss about these topics during 40 minutes with concrete examples of initiatives and projects empowering digital sovereignty in Europe.

Forge Federation in the Context of Open Science and Research-Based Design

Originally created for developing the Linux kernel, Git has over time become the cornerstone of global digital development practices. Its popularity has truly exploded with the invention of GitHub, which has coupled Git with a web interface, thus spreading the use of collaborative development platforms today known as 'forges'. Today, the main use case of a forge is software development, but new types of forges are slowly emerging, such as educational forges or design forges. Considering the diversity of backgrounds and expectations of these new kind of users (teachers, researchers, designers, …), there's a real need for a more open and decentralized ecosystem of forges. In this presentation, we will particularly focus on challenges regarding forge federation and the constraints and expectations of forge users in the context of the “open science” movement, the rise of hybrid environments involving research-based design, and more broadly, 'citizen development'.

Using UniTime to build optimized academic schedules

UniTime is a comprehensive software solution that addresses a wide array of academic timetabling and scheduling needs, such as course and examination timetabling, student and instructor scheduling, and event management. It effectively balances the often competing objectives of various stakeholders and is currently utilized by over 100 institutions globally, ranging from small colleges to large universities with over 50,000 students. While UniTime doesn't employ AI in the conventional sense (machine learning and large language models), it leverages Constraint Programming techniques, a subfield of AI that focuses on problem-solving and complex decision-making. This approach offers flexibility and scalability in problem modeling and in the algorithms used to solve NP-hard problems, which are computationally challenging for all but the smallest instances. UniTime is an open-source project born from joint research by multiple universities, successfully bridging the gap between research and practical application in educational timetabling. The UniTime solver won the international timetabling competition ITC 2007. Furthermore, the data collected by UniTime and its course timetabling problem were used to organize the ITC 2019 competition, contributing real-world benchmark datasets back to the timetabling research community.

Exploring Chip Design with Open Source Electronic Design Automation

This talk will begin with an overview of Electronic Design Automation (EDA)—the essential workflow that enables chip designers to analyze, design, and verify semiconductor chips before fabrication. Despite its critical role, the EDA industry is dominated by a triopoly controlling nearly 90% of the market, creating a highly restrictive environment. The lack of open formats and the high cost of licenses pose significant barriers, particularly for newcomers, restricting innovation and limiting access to chip design exploration. Until recently, Open Source alternatives in EDA were nearly nonexistent—even foundational tools like hardware description language parsers and or chip data manipulation APIs were missing. However, a new Open Source ecosystem is emerging, offering a new approach. While these tools may not yet compete with proprietary solutions for cutting-edge chip manufacturing, they provide a viable path for learning, prototyping, and delaying costly licensing investments until necessary. This talk will explore the current landscape of Open Source EDA, covering available tools for each step of the design flow. It will also highlight the contributions of the KeplerTech.io team to this growing ecosystem, showcasing how Open Source is making chip design more accessible and fostering innovation beyond the traditional industry constraints.

Citizen-Dataset for fighting misinformation online. A new participatory dataset.

Collecting data is a crucial step for the development of AI tools. The most common approach to data creation is scraping contents and behaviours of users-generated contents mainly online, and use crowdsourcing platforms or relatives (colleagues, students, and so on) for the annotation. However, recently, some scholars advanced some alternative methods that involve people at different steps and levels during AI-based service development (Delgado et al., 2023). Following their proposal, we designed the Citizen-Dataset Lab, a laboratory with the purpose of creating datasets with people in order to involve them in the process of dataset creation used for training models, and guarantee that their opinions/decisions are embedded in the annotated dataset. Indeed, current technology is designed and delivered by W.E.I.R.D. researchers without consulting the real needs of citizens or including perspectives coming from disadvantaged communities (Dignum, 2023). The design of our lab is based on 5 principles: (1) Ensure diversity in dataset creation and annotation; (2) Promote participation, empowering people to decide which are the contents that must be included in a dataset, and explaining to them how technologies use data; (3) Consider subjectivities in the creation of schema of annotation and guidelines; (4) Democratize technologies co-shaping the service with people, collecting impressions about the annotation process and discussing the potential uses of the developed resource; and (5) Embrace Open Source. In fact, datasets and technologies resulting from this laboratory will be open source and available to the community. The first edition of Citizen-Dataset Lab (February-May) focuses on misinformation. The spreading of misinformation is strongly related with the growth of ideological polarization in the EU (Vasist et al., 2024). Communities of people exposed to opposed media diets become ever more conflictive in the online conversation, with worrying effects in the real world. Therefore, we believe that machines should not classify news as true or false, but support people in grasping the complexity of our media environment and in understanding other views of the world. In this context, Citizen-Dataset Lab will help us to shape the new features of Debunker-Assistant, an open source product for fighting misinformation (Capozzi-Lupi et al., 2023), building a multilingual dataset to make Debunker-Assistant better and fairer in supporting people against misinformation.
