Production RAG API for developers: parse, extract and search documents with SOTA OCR and cited retrieval, cloud or on-prem.

What it does

LightOn offers a production-ready multimodal RAG API built on its open-source retrieval and OCR models. Three endpoints—parse, extract and search—turn documents into structured Markdown, pull fields into JSON, and return grounded answers with chunk-level citations. It is MCP-native, LLM-agnostic and supports enterprise deployment with SSO, ACLs and EU sovereign hosting.

How to use: Enterprises can use LightOn's platform to build custom AI tools, query GenAI models, enhance knowledge retrieval, and deploy AI solutions tailored to their specific needs. They can also leverage LightOn's support and consulting services for successful implementation.
