arXiv: Operationalizing Document AI with microservice OCR/LLM pipelines

Researchers published a production architecture for document AI: a microservice pipeline combining OCR, classification, and LLM extraction processing thousands of multi-page documents per hour. Separates GPU-bound inference from CPU orchestration for cost efficiency.

WHY IT MATTERS

Blueprint for banks and insurers scaling document automation (KYC, claims processing, underwriting); open-source pattern may accelerate in-house document AI projects over vendor lock-in to platforms like Sardine.
