LightOn

Développer sa recherche IA en interne ou adopter une solution éprouvée ? Quels coûts, quels délais et quel retour sur investissement ?

Le mardi 24 novembre à 14h00, retrouvez nos experts pour notre webinar « IA Search souveraine : Build ou Buy ? ».

La pertinence d’une IA dépend de sa capacité à retrouver la bonne information dans vos documents. Comment construire cette base tout en gardant la maîtrise de vos données ?

Au programme :
🔍 Le rôle de la recherche documentaire dans la qualité des réponses de l’IA.

⚖️ Build ou Buy : les critères pour comparer les coûts, les délais de déploiement et le retour sur investissement.

⚙️ Une démonstration live de LightOn Suite pour découvrir comment créer des workflows agentiques adaptés à vos métiers.

💬 Un temps d’échange avec nos experts pour poser vos questions et parler de vos projets.

The answer your team needs might be inside a chart on page 47 of a scanned report. 📄

Making it searchable starts with understanding more than the words on the page.

LightOnOCR-3 extracts data from charts and generates image descriptions, making visual information available for search alongside the document’s text.

A chart becomes structured data. An image gets a description that a search system can use.

That’s the connection between document understanding and enterprise search. LightOn Core takes the next step: indexing company information and making it retrievable for AI applications.

What if the answer was there all along, just hidden in thousands of documents? 🐈

Oscar disappeared five years ago. But his story didn't end there.

A veterinary record under another name. A photo in an archived report. A reference in a shelter's database.

Different sources. Different formats. One missing cat.

With LightOn, the clues come together in under 15 minutes, with every finding linked to its source.

Because sometimes, the answer isn't missing. It's just waiting to be found.

LightOn releases SlideOn & mSlideOn: open SOTA sparse retrievers at 174M and 339M params.

Dense retrieval works, but at enterprise scale it gets expensive. Every document becomes a vector, and fast vector search usually runs on GPUs.

Sparse retrieval changes the economics. Documents go into an inverted index, and each query only reads the documents that share its active features.

→ Search that scales to billions of documents
→ Fast search that can run on CPU
→ A smaller index to store

And quality holds up:

→ SlideOn: 56.68 on BEIR-15, above our dense model DenseOn (56.20)
→ mSlideOn vs mDenseOn: +4.76 on multilingual (MIRACL), +10.18 on long documents (MLDR), +3.25 on code (MTEB Code)
→ Prune vectors at inference to fit your latency and storage budget, with no retraining

Under the hood: we converted DenseOn and mLateOn into sparse retrievers through SAE pretraining and fine-tuning. Both models learn their own vocabulary of 32,768 concepts instead of using the tokenizer’s vocabulary.

Fully open: models, intermediate SAE checkpoints, training data and scripts.

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.
