LUMIÈRE : faire du calcul une infrastructure nationale, comme la France l’a fait pour l’énergie et les télécoms. Le consortium LUMIÈRE — Sesterce, @Core_Scientific et @AVAIO — annonce sa volonté d’investir 20 Md€ pour construire 2 GW d’infrastructures de calcul IA en France, réparties sur deux sites (2 campus de 1 GW). Hier et ce matin, nous avons présenté ce plan au Gouvernement et à l’Élysée. LUMIÈRE repose sur un modèle clair : une gouvernance majoritairement française et européenne, associée à des leaders américains du secteur pour exécuter en France avec des standards industriels de tout premier rang. LUMIÈRE : faire du calcul une infrastructure nationale, comme la France l’a fait pour l’énergie et les télécoms. C’est ce choix d’infrastructure — durable, mutualisé, structurant — qui a permis à la France de bâtir sa puissance industrielle. Et c’est par la même logique, appliquée au calcul, que la France éclairera encore le monde : en transformant l’innovation en capacité nationale, au service des usages critiques, de l’industrie et de la souveraineté. Nous nous réjouissons du dialogue engagé avec les équipes de l’État, afin de faciliter la coordination nécessaire à la sécurisation des conditions d’exécution (énergie, raccordements, foncier, autorisations), dans le respect des procédures. Nous remercions M. Emmanuel Moulin, Secrétaire général de la Présidence de la République, M. @RolandLescure , ministre de l’Économie, des Finances et de la Souveraineté industrielle, énergétique et numérique, Mme @ALehenanff, ministre déléguée chargée de l’Intelligence artificielle et du Numérique, ainsi que M. @matthieulandon1, conseiller du Président de la République (économie), et Mme @VVandeville, conseillère du Président de la République (attractivité & export), pour la qualité de leur écoute et l’opportunité de présenter ce plan pour faire rayonner la France sur l’IA. ---------------------------------------- LUMIÈRE: making compute a national infrastructure — just as France did for energy and telecommunications. The LUMIÈRE consortium — Sesterce, Core Scientific and AVAIO Capital — has stated its intent to invest €20bn to deliver 2 GW of AI compute infrastructure in France, across two sites (two 1 GW campuses). Yesterday and this morning, we presented the plan to the French Government and the Élysée. LUMIÈRE is built on a clear model: French & European majority governance, combined with US industry leaders to execute in France at world-class industrial standards. LUMIÈRE is about turning compute into national infrastructure — just as France did for energy and telecom networks. This is how France has historically transformed innovation into lasting national capability. Applying the same logic to compute is how France will keep lighting the way: by building durable, shared, strategic capacity for critical use cases, industry, and sovereignty. We welcome the constructive dialogue with public teams to help coordinate the conditions required for execution (power, grid connections, land and permitting), with speed, clarity, and full respect of due process. We thank Mr Emmanuel Moulin , Secretary General of the Presidency of the Republic, Mr @RolandLescure , Minister of the Economy, Finance and Industrial, Energy and Digital Sovereignty, Ms @ALehenanff, Minister Delegate for AI and Digital, as well as Mr @matthieulandon1, Economic Adviser to the President of the Republic, and Ms @VVandeville, Adviser to the President of the Republic (attractiveness & exports), for the opportunity to present the LUMIÈRE plan and strengthen France’s AI leadership. @_Adam_Sullivan1, @russellcann, Ryan dewar, @MMcC_gynonc, John Malone, Marie Jousset, @adrien_trl, Domitille Legrand, Julien Talagrand #Lumiere #Sesterce #CoreScientific #AVAIOCapital #AICompute #HPC #CriticalInfrastructure #DigitalSovereignty #France #Europe #IndustrialStrategy

From Energy Exporter to AI Powerhouse: Why France Holds the Cards. 🌍 In his latest op-ed for La Tribune, our chairman Anthony Tchakerian argues that France is at a strategic inflection point. With abundant, low-carbon, dispatchable nuclear power, the country faces a clear choice: keep exporting largely commoditized electricity—or convert that advantage at home into 21st-century value: compute, and the AI capabilities it enables. At Sesterce, we believe the highest value is created not by moving electrons across borders, but by turning them into processing power. That’s why we are building the critical infrastructure—AI factories—that transforms competitive energy into intelligence, jobs, and technological sovereignty, here in France. This requires a pragmatic partnership between the public sector and the tech industry: long-term visibility, stable and competitive energy pricing, and a clear commitment to high-performance computing as critical national infrastructure—on par with grids and telecom networks. 🔗 Read the full opinion piece: latribune.fr/article/la-trib… ------------------------------------- De l’export d’énergie à la puissance IA : pourquoi la France a les cartes en main. 🌍 Dans son nouvel article publié dans La Tribune, notre président Anthony Tchakerian défend une conviction simple : la France est à un moment charnière. Grâce à un parc nucléaire décarboné et pilotable, nous avons un choix stratégique : continuer à exporter une énergie peu valorisée, ou la transformer sur notre sol en valeur économique et industrielle — la puissance de calcul, au cœur de l’IA. Chez Sesterce, nous partons d’un principe : la valeur ne se situe plus uniquement dans les électrons, mais dans ce qu’ils permettent de produire. C’est pourquoi nous développons des infrastructures de calcul — de véritables “usines à IA” — capables de convertir une énergie compétitive en capacité d’innovation, en emplois, et en souveraineté technologique. Cette ambition suppose un alignement clair entre État, énergie et industrie : visibilité de long terme, prix stables et compétitifs, et reconnaissance du calcul haute performance comme une infrastructure critique, au même titre que les réseaux ou les télécoms. 🔗 Lire la tribune complète : latribune.fr/article/la-trib… #ArtificialIntelligence #EnergyInfrastructure #HPC #Sesterce #TechSovereignty

What an amazing few days we had in San Francisco! Sesterce team was right in the thick of things at the PyTorch Summit (Oct 22-23), and let me tell you, the energy was absolutely buzzing. The big takeaway? The future of AI isn’t just about creating larger models; it’s about making them faster, more efficient, and ready to deploy everywhere. Here are our three key takeaways from the summit: • Performance is the New Frontier: The spotlight has shifted from merely achieving model accuracy to optimizing performance. We delved deep into torch.compile and explored new techniques to significantly reduce inference latency and training costs—something we’re really passionate about in FinOps for AI. • GenAI in Production is Maturing: The discussions are evolving from "what if" scenarios to "how to" implement them. Sessions on scalable deployment, model sharding, and managing complex AI pipelines clearly show that the industry is committed to taking these powerful models from the lab to real-world applications. • The Rise of On-Device & Edge: There’s a strong push for more efficient models that can operate on the edge. This is a game-changer for data privacy and real-time applications, but it also brings a new challenge: managing a distributed, hybrid AI infrastructure. It’s evident that the next wave of AI innovation will hinge on the cloud infrastructure that supports it. Building, training, and deploying these models at scale demands a robust, high-performance, and cost-effective cloud strategy. It was fantastic to connect with so many developers and leaders who are shaping the future of AI. We’re heading back with a wealth of new ideas! #PyTorchCon #AI #PyTorch #SesterceGroup
