Operationalizing Document AI: A Microservice Architecture for OCR and LLM Pipelines in Production

In three linesMicroservice architecture for Document AI pipelines in production: classification, OCR, and structured field extraction via LLM. Processes thousands of multi-page documents per hour. Key findings: OCR dominates end-to-end latency (not LLM parsing), system saturation determined by shared GPU capacity. Concrete architectural patterns for production deployment.
