LightOn announces highly successful IPO on Euronext Growth Paris

In Paris, on June 19, 2025, Lighton, a leading European provider of enterprise-grade generative AI for the public and private sectors, introduced secure artificial intelligence to the core of Sodern’s operations. In response to burgeoning demands for sovereignty and performance, Sodern has made the shrewd decision to deploy Paradigm, LightOn’s generative AI platform, across its organization. The result: the genesis of a deep transformation of its processes and operations, enhancing productivity while maintaining the highest standards of security.

The recent release of ModernBERT by LightOn and AnswerAI aims at providing the best base model that can be then used in different industry verticals. Today, Thomas Sounack from the Dana-Farber Cancer Institute in collaboration with researchers at Harvard University, LightOn, MIT, McGill University, Albany Medical College and Microsoft Research, used this capability and trained a new State-Of-The-Art (SOTA) medical encoder named BioClinical ModernBERT.

After the recent release of GTE-ModernColBERT exhibiting state-of-the-art results on long-context retrieval, LightOn announces a major leap forward in AI-driven knowledge discovery: Reason-ModernColBERT, an open-source multi-vector model purpose-built for Deep Research applications.
