Paris Open Source AI Summit

The Paris Open Source AI Summit (POSAIS) returns to one of Europe's most prestigious stages on July 10th, 2026, bringing together the builders, engineers, and researchers who are actively shaping the future of open source artificial intelligence. This isn't a conference for spectators — it's a gathering for those who write the code, curate the datasets, publish the weights, and make the hard architectural decisions that define how AI systems actually work. Taking place at Studio 104 in the iconic Maison de la Radio et de la Musique, POSAIS occupies the same 800-seat legendary hall that has hosted Sting, Eric Clapton, and major international forums. The venue choice is deliberate: hosting this event in a public institution historically dedicated to the free sharing of knowledge reflects the open source belief that what deserves to be said deserves to be heard by everyone. ## Who Should Attend POSAIS is designed for three core audiences: CTOs, CIOs, and engineering leaders who chose open weights over proprietary APIs and are navigating sovereign infrastructure challenges; data scientists and ML engineers actively training and fine-tuning models in production; and researchers and academics who publish their weights, training logs, and yes, their failures — those who believe European AI sovereignty starts in a git repository. ## Five Critical Streams The day is structured around five no-filler tracks that address the most pressing challenges in open source AI: Geopolitics & Sovereignty examines why mastering open source AI is a strategic imperative rather than a tech preference, mapping the real power dynamics and Europe's position within them. State of the Art features live demos, honest benchmarks, and hard conversations about what actually works at scale — covering models, infrastructure, datasets, and deployment with hands firmly in the code. Building the Coalition tackles how we federate, fund, and sustain open source AI as a global commons, exploring viable economic models, necessary standards, and strategic alliances. Impact & Empowerment explores how open source AI redistributes power to the Global South, education systems, and communities traditionally excluded from the AI conversation. New Frontiers: Physical AI opens with a live demo of a Unitree humanoid robot on stage, then dives into embodied AI, open source VLA models, sim-to-real transfer, and the collision point where open source meets robotics.
