Executive Architecture Summary

Enterprises in healthcare, banking, legal, and defense cannot risk sending confidential intellectual property, PII, or internal documents to external third-party AI APIs. i26 designs and deploys air-gapped Retrieval-Augmented Generation (RAG) and specialized reasoning pipelines directly within your dedicated AWS, GCP, or on-prem VPC.

The Enterprise Challenge & Cost Liabilities

Public commercial LLM APIs introduce profound compliance and security vulnerabilities: - Risk of corporate IP or confidential contract text being ingested into commercial foundation models. - Stringent regulatory barriers (HIPAA, GDPR, SOC2, PCI-DSS) that penalize cloud data transfer outside defined jurisdictions. - Expensive token pricing models that penalize high-throughput automated document parsing and internal tooling.

The i26 Engineering Solution & Blueprint

i26 implements an enterprise-grade, fully sovereign AI architecture: - **Quantized Open-Weights Engine**: vLLM and TensorRT-LLM serving Llama 3 70B and Mistral on dedicated GPU instances (NVIDIA H100 / A10G) with auto-scaling to zero. - **Tenant-Isolated Vector Store**: pgvector on self-hosted PostgreSQL or Qdrant cluster with role-based access control (RBAC) and row-level document security. - **Hybrid Retrieval Pipeline**: Dense embedding vector search combined with sparse lexical BM25 indexing and cross-encoder reranking to ensure verifiable citations with zero hallucinations.
