Introducing LightOn Suite! 🚀 Enterprise AI needs more than powerful models. It needs access to the right information, and a way to turn that information into useful applications. Today, we're launching LightOn Suite, bringing together two complementary products: 🔷 LightOn Core : transforms enterprise documents into structured, searchable knowledge that AI can use. From parsing and indexing to retrieval, with access permissions and traceability back to the original sources. 🔷 LightOn Apps : builds on Core to let teams create and deploy AI applications using their own company knowledge. From internal search and contract analysis to supplier comparisons and document workflows. Together, they provide a shared knowledge foundation that can support multiple AI applications, without rebuilding the document infrastructure for every use case. 🤝 And we're teaming up with @Scaleway to make it available on European cloud infrastructure. LightOn Suite is now available on @Scaleway 's French cloud, in SaaS and Managed VPC deployments. Scaleway is also making LightOnOCR-3 available through its Generative APIs, bringing our document intelligence models directly to developers. 👉🏻 Explore LightOn Core : lighton.ai/product/core 👉🏻 Discover LightOn Apps: lighton.ai/product/apps

🔎 Is one vector enough to capture everything that matters in search? Traditional single-vector search compresses information into a single embedding. But what happens to the context that's lost along the way? On October 19, our @AmelieTabatta , Head of Training & Inference at LightOn, will join @treygrainger and @TurnbullDoug for a technical session on Late Interaction in 2026, hosted on Maven. They'll explore: 🔹 Why token-level embeddings can improve retrieval quality 🔹 Where late interaction makes the biggest difference 🔹 How approaches like NextPlaid are making retrieval more efficient 🔹 What it takes to scale late interaction in production 📅 October 19, 2026 | 5 PM CEST 💻 Online | Free registration 👉 Join the discussion: maven.com/p/2f6bf9/beyond-si…

World-leading document recognition. Beyond text extraction. Introducing LightOnOCR-3, our new family of state-of-the-art AI models for document intelligence.

LightOn × @infocom94 : Rencontres du numérique territorial. Pour cette première édition, @infocom94 a réuni plus d’une centaine de participants, parmi lesquels des acteurs technologiques et des représentants des collectivités, pour partager leurs problématiques, échanger sur leurs pratiques et mutualiser leurs connaissances et outils technologiques. En tant que partenaire d’Infocom 94, notre Head of Customer Services & Solutions, Gauthier Zuppinger, a pris la parole lors de la table ronde sur la souveraineté numérique pour aborder ce que signifie concrètement disposer d’une technologie souveraine, ainsi que les risques et les enjeux liés à l’utilisation de technologies non souveraines. L’ambition d’Infocom 94 d’apporter aux collectivités des solutions réalistes, pragmatiques et frugales rejoint pleinement nos valeurs et l’ADN de LightOn. Merci à Vincent Kerbiquet, à @AmbroiseToin président d’Infocom 94, et à TerikSene pour leur confiance et leur invitation à cette première édition !

Building AI search is one thing. Maintaining it in production is another. 🔍 New formats, permissions, retrieval quality, infrastructure, maintenance... and what happens when the people who built it leave? 🧠 Our latest article looks at the real cost of building enterprise AI search in-house, and when it makes more sense to buy. With LightOn Console, the search infrastructure is already there. Your team can focus on the application. 👉🏻 Read the article: lighton.ai/lighton-blogs/bui… 👉🏻 Explore Console: console.lighton.ai/

🤝 @eurodecision × @LightOnIO : allier science de la décision et IA générative. LightOn s’associe à @eurodecision , expert en Mathématiques Décisionnelles, Recherche Opérationnelle et IA, pour aider les organisations à mieux exploiter leurs données et leurs connaissances et à prendre de meilleures décisions grâce à l’IA. 🎯 L’objectif ? Combiner l’expertise d’EURODECISION en modélisation et optimisation avec celle de LightOn en IA générative pour développer des outils d’aide à la décision plus performants, plus rapides à déployer et plus simples à utiliser. Cette collaboration s’inscrit notamment dans la dynamique du PIIEC-IA, qui vise à accélérer l’intégration de l’IA dans l’industrie et à faire émerger une offre européenne d’IA à forte valeur ajoutée. Concrètement, plusieurs cas d’usage sont au cœur de cette collaboration : - Gestion des connaissances : analyser et exploiter des documents techniques, spécifications, normes, rapports de maintenance ou données métier. - Ingénierie logicielle : analyser les exigences et accompagner la rédaction de documentation technique et la génération de tests. - Modélisation & optimisation : identifier les modèles et approches adaptés à des problématiques de planification et d’optimisation sous contraintes. - Analyse & aide à la décision : expliquer les résultats des modèles en langage naturel et comparer différents scénarios « What-If ». Un partenariat pour transformer des problématiques complexes en décisions concrètes. 👉🏻 eurodecision.com/ 👉🏻 lighton.ai/ #IA #IAGenerative #AideALaDecision #RechercheOperationnelle #Optimisation

Your documents are not general-purpose, Your retriever should be good beyond these @tomaarsen recently fine-tuned mLateOn-unsupervised for medical retrieval using MIRIAD, a benchmark with 1,000 queries and 200,000 passages. Out of the box, mLateOn reached 0.8520 NDCG@10. After a short fine-tuning run on a single RTX 3090, mLateOn-medical reached 0.9139, outperforming every general-purpose retriever tested. Qwen3-Embedding-4B, the strongest dense model in the evaluation, reached only 0.7817, despite having roughly 33 times more active parameters. The difference comes down to how information is represented. Dense models compress an entire document into one vector. Late-interaction models preserve token-level representations, allowing them to capture signals that single-vector models may average away. This matters even more for long, specialized documents. In this evaluation, passages averaged 941 tokens. The conclusion is simple: strong retrieval is not only about building larger models. It is about choosing an architecture that can understand your documents and adapt to your domain. → Explore Tom Aarsen’s complete fine-tuning guide : huggingface.co/blog/train-mu… → Put advanced retrieval to work with LightOn Console console.lighton.ai

All your agent needs is search It gives them access to the right enterprise knowledge, grounds their responses in reliable evidence, and reduces hallucinations. But performance alone is not enough. For AI agents to operate at scale, they also need to make economic sense. An infinite context window is not an efficiency strategy. By retrieving only what matters, good retrieval reduces unnecessary context, lowers token usage, and makes every inference more cost-effective. Powerful agents are useful. Powerful and efficient agents are production-ready. 👉🏻 Start building with LightOn Console: console.lighton.ai

New State-of-the-art Retrieval Model / Новая передовая поисковая модель / 全新最先进检索模型 / 최첨단 검색 모델 / 最先端の新しい検索モデル / نموذج استرجاع جديد متطور One retriever family for the languages your data actually speaks. Multilingual retrieval, built for production. A few months ago, LightOn open-sourced DenseOn and LateOn, its 149M-parameter retrievers. A new BEIR state of the art for their size class, Apache 2.0. Today, the multilingual pair: mDenseOn and mLateOn. 307M parameters. SOTA on BEIR, MLDR, MIRACL and MTEB Code. Nine languages, one quality bar: English, French, German, Spanish, Italian, Portuguese, Swedish, Norwegian, Arabic. Late interaction compounds. mLateOn stays competitive retrieving in languages and scripts it never saw in training: Cyrillic, Japanese, Korean, Chinese. It breaks the ceiling of translate-train pipelines. Everything open: models, datasets, training code. 👨‍🍳Kudos to @raphaelsrty @antoine_chaffin @paulomouraj @AmelieTabatta 🔗Read the full story: lighton.ai/lighton-blogs/mde… ⚡️Try it now: console.lighton.ai/signup
