The Industrial Rag API
For Enterprise Developers
A production-ready search & retrieval API designed for organizations where data control, compliance, and deployment flexibility are non-negotiable.
RESTÂ API
OpenAPI V3
On-Premise
Private Cloud
Built in France
Buy vs. Build
You've Built Internal RAG
Now You Need It to Scale
Now You Need It to Scale
Parser maintenance. Model updates. Chunking edge cases. Vector DB scaling. That's infrastructure work, not product work.
Offload the plumbing. Keep the control.
Without Paradigm API
Your current reality
Ongoing Maintenance
Parsers, OCR, chunking logic...
Custom ACL Implementation
Synced with your IAM
GPU Scaling
And inference optimization
Model Upgrades
Regression testing
OpenAPI V3
With Paradigm API
Universal Ingestion Endpoint
PDF, Office, scans, HTML. We handle extraction and semantic chunking.
Native Workspace & Collection Isolation
SSO/SAML integration, audit logs out of the box.
Managed Pipeline
Optimized for low-footprint deployment (on-prem or private cloud).
Versioned API V3
Backward compatibility, controlled rollout.
Core Capabilities
A Full-Stack RAG Pipeline in a Few Endpoints
We expose the full power of the Paradigm platform through a versioned, stable API
Smart Collections
Smart ingestion & collections
Don't just dump text. Organize knowledge into Collections. Upload raw files (PDF, scans, Office) via API; our engine handles the cleaning, OCR, and semantic chunking automatically.
Hybrid Search
Semantic retrieval & reranking
Beyond keywords. Our backend orchestrates Hybrid Search (Dense + Sparse) and automatic Reranking to ensure the retrieval quality is production-ready.
Verified Output
Grounded generation with citations
The /chat endpoint returns answers grounded in your Collections, providing precise citations (source document + page number) in the JSON response for full UI transparency.
Private AI
Your IP is your competitive edge. Don't feed it to public models.
Don't Trust Promises
Trust Architecture
Most vendors ask you to trust their contracts. We rely on physics. Rather than promising we won't look at your data, we deploy where we technically can't access it.
Air-Gapped (Offline)
On-Premise
Sovereign Hybrid
The LightOn Garantee
We don't just promise privacy. We make data exfiltration technically impossible.
Hardware Efficiency
Maximum Intelligence
Minimum Hardware Footprint
Minimum Hardware Footprint
Enterprise AI shouldn't require a nuclear power plant.
Our Search is engineered to run on constrained infrastructures (On-Premise or Private Cloud), maximizing the "Performance per Token" ratio.

Optimized
We build and fine-tune specific Models to RAG tasks.
Quantization Mastery
High-speed inference with low VRAM usage.
Cost-Efficient Scaling
Scale your API usage without linearly exploding your GPU budget.
