AI Summit is back
AI Summit is back
POSAIS is the day when those who build, develop, and deploy open-source AI come together: a unique gathering to understand the trends, debates, and new rules of a movement that is rapidly accelerating.
Watch Last Year Video :
Paris Open Source AI Summit (POSAIS) took place, bringing together global leaders, researchers, policymakers, and industry experts.
The event provided a platform to build a shared understanding and common language around the state of Open Source AI, while showcasing its most recent achievements and its potential to drive positive change.
Through keynotes, panel discussions, and interactive workshops, participants exchanged insights on best practices, ethical frameworks, and public policy initiatives aimed at fostering open, equitable, and accessible AI.
Last year a particular focus was placed on how Open Source AI can help address global challenges, providing solutions that benefit humanity and amplifying the participation of the Global South in building a truly universal AI ecosystem.
Organized as part of the “Road to the Summit” initiative, POSAIS 2025 served as an essential milestone leading up to the AI Action Summit, scheduled for February 10–11, 2025, under the French Presidency.

Hackathon - Instruction Dataset for LUCIE
Making a universal IA model better by "Instruction dataset for LUCIE" hackathon: a collaborative initiative for a truly LLM aligned with european and ethical values
This sequence is exclusively dedicated to the Open Source Large Language Model, LUCIE. Throughout the day, participants will have the opportunity to explore the journey of LUCIE and participate to the hackathon. This hackathon aims to mobilize the OpenLLM France community and other participants to create the largest dataset of instructional data in French, designed to train Open Source models like LUCIE. The goal is to collect, annotate, and create a set of 100,000 to 200,000 Q/A pairs.
